Answer:

The y-intercept of the line is -4.

Step-by-step explanation:

y-y=m(x-x¹)

y-(-2)=-1(x-(-2))

y+2=-1x-2

-2 -2

y=-1x-4

Answer:

the slope of a parallel line is m=2.

Step-by-step explanation:

this equation is in standard form. convert to y=mx+b to find the slope

m=slope

4x - 2y = -12

subtract 4x on both sides

-2y = -4x - 12

divide by -2

y = 2x + 6

the slope of this line is m=2.

since the question is asking if a line parallel to this line, the slopes are the same.

the slope of a parallel line is m=2.

Answer:

y=2x+6

Step-by-step explanation:

y=mx+c

-2y=-4-12

y=(-4x/-2)-12/-2

y=2x--6

y=2x+6

By dividing both sides by (A - a), we obtained p = A / (A - a). Therefore, the correct answer is (B) p = A / (a + H).

To solve the equation A = aP + pH for p, we need to isolate the variable p. Let's go through the steps:

A = aP + pH

To isolate p, we will rearrange the equation:

A - aP = pH

Next, we can factor out p:

p(A - a) = pH

Now, we divide both sides of the equation by (A - a):

p = pH / (A - a)

Lastly, we can divide both numerator and denominator by H:

p = (pH / H) / (A - a) = p(H / H) / (A - a) = p / (A - a)

Therefore, the equation is simplified to:

p = A / (A - a)

Hence, the correct answer is (B) p = A / (a + H).

Answer:

First, we can write:

x = 2 . ¯ 3

Next, we can multiply each side by  10 giving:

10 x = 23 . ¯ 3

Then we can subtract each side of the first equation from each side of the second equation giving:

10 x − x = 23 .¯ 3 − 2 . ¯ 3

We can now solve for  x  as follows:

10 x − 1 x = ( 23 + 0 . ¯ 3 ) − ( 2 + 0 . ¯ 3 )  ( 10 − 1 ) x = 23 + 0 . ¯ 3 − 2 − 0 . ¯ 3  

9 x = ( 23 -2 ) + ( 0 . ¯ 3 − 0 . ¯ 3 )  

9 x = 21 + 0

9 x = 21

9 x /9 = 21 /9

9 x /9 = 3 × 7 /3 × 3

x = 3 × 7 /3 × 3

x = 7 /3

Step-by-step explanation:

Step one:

given data

we are told that the uber charges $1.25 per mile

and that Leo also gave a tip of $5

the function for the total charge is given as

y=mx+c

Step two:

we will use the notation m for the number of miles traveled

given that the total trip is $16.25

16.25=1.25m+5

solving for m we have

16.25-5=1.25m

11.25=1.25m

divide both sides by 1.25

m=11.25/1.25

m=9

So he travelled 9miles

Yes because (50)(0.25) and (50)(1 - 0.25) are both at least 10. This means we can use the normal distribution to model the distribution of sample portions.

What is a Normal distribution in statistics?

Data in a normal distribution are symmetrically distributed and have no skew. The majority of values cluster around a central region, with values decreasing as one moves away from the center. In a normal distribution, the measures of central tendency (mean, mode, and median) are all the same.

25% = 0.25

Then (50)(0.25) > 10 and also (50)(1 - 0.25) > 10.

Hence, we can use the normal distribution to model the distribution of sample portions.

Trapezoid:

A trapezoid, also known as a trapezium, is a flat closed shape having 4 straight sides, with one pair of parallel sides. The parallel sides of a trapezium are known as the bases, and its non-parallel sides are called legs.

Here we have to find the area of the trapezoid.

Formula to find the area:

Area = 1/2 ( sum of the parallel base ) height

Here we are provided with two bases 16.2m and 10.8m

Height = 9.6m

Area = 1/2 ( 16.2 + 10.8) 9.6

        = 1/2 × 27 × 9.6

        = 27 × 4.8

        = 129.6m²

Step-by-step explanation:

Answer:

≈ 3.9 miles

Step-by-step explanation:

The third angle in the triangle is

180° - (53 + 78)° = 180° - 131° = 49°

Using the Sine rule in the triangle with distance from 2 being x, then

\(\frac{3}{sin49}\) = \(\frac{x}{sin78}\) ( cross- multiply )

x × sin49° = 3 × sin78° ( divide both sides by sin49° )

x = \(\frac{3sin78}{sin49}\) ≈ 3.9 ( to the nearest tenth )

The formula for the monthly loan payment is given as

Where

P = loan amount ( initial principal) = $15000

A= Payment amount per period = ?

r = interest rate per period = (5/12) x (1/100) =0.0041667

n = total number of payments or periods = 4 years = 4 x 12 = 48 months

Substituting all these into the above equation gives

So each month he pays $345.44 to the nearest cent

B)

The total interest for the loan is given by

Total amount paid over the total period of time - Original amount borrowed

Total amount paid over the total period of time = 345.44 x 48 months = $16581.12

The total interest of the loan hence = $16,581.12 - $15,000 = $1,581.12

The total loan interest to the nearest cent = $1,581.12

The equivalent equation for a two-input XOR gate is y = ab’ + a’b.

A two-input XOR gate is a logic gate that outputs a high or 1 signal only when the two inputs are different. In other words, the output of an XOR gate is 1 when one input is 0 and the other input is 1, and vice versa.

To represent an XOR gate with an equation, we can use Boolean algebra. The Boolean expression for an XOR gate is y = ab’ + a’b, where y is the output, a and b are the two inputs, and a' and b' represent the complement (or NOT) of a and b, respectively.

This equation can be derived using the laws of Boolean algebra. For example, we know that the product of a variable and its complement is always 0, i.e., a a' = 0. Using this property, we can simplify the equation y = ab’ + a’b as follows:

y = ab’ + a’b
 = ab’ + ab’’ + a’b     (adding a' and b')
 = ab’ + a’b + ab’’    (rearranging terms)
 = ab’(1) + a’b(1)     (using a a' = 0 and b b' = 0)
 = ab’ + a’b            (simplifying)

Suppose x is the number of times a woman is selected when 3 people are randomly chosen from a group of 2 women and 2 men, the possible values of x are 0, 1, 2, and 3.

When 3 people are randomly chosen without replacement from a group of 2 women and 2 men, there are a total of 4C₃ = 4 possible outcomes, which we can list as follows:

WWx (two women and one of either gender)

WMx (one woman, one man, and one of either gender)

MWx (one man, one woman, and one of either gender)

MMx (two men and one of either gender)

In each of these outcomes, x represents the number of times a woman is selected. We can see that the possible values of x are 0, 1, 2, and 3, depending on which outcome occurs.

In outcome 1 (WWx), a woman is selected twice, so x = 2.

In outcomes 2 (WMx) and 3 (MWx), a woman is selected once, so x = 1.

In outcome 4 (MMx), no women are selected, so x = 0.

Therefore, the possible values of x are 0, 1, 2, and 3.

AB is congruent to BC given BE bisects DBC and BE is parallel to AC is proved .

What is congruent ?

Congruent refers to having the same shape and size. In mathematics, two objects are said to be congruent if they are identical in shape and size, and can be superimposed onto one another. The symbol used to represent congruence is ≅. Congruence applies to various geometric objects, such as triangles, rectangles, circles, and more. When two objects are congruent, they have all corresponding angles equal and all corresponding sides equal in length.

Step 1: Statement: \($\angle DBE = \angle EBC$\)

Reason: Given that overline BE bisects \($\angle DBC$\)

Step 2: Statement: \($\angle DBC + \angle EBC = 180^\circ$\)

Reason: Angle sum property of a straight line.

Step 3: Statement: \($\angle ABC + \angle EBC = 180^\circ$\)

Reason: Angles on a straight line sum to \(180^\circ$, and $\overline{BE} || \overline{AC}$\) implies that \(\angle ABC$ and $\angle EBC$\) are co-interior angles.

Step 4: Statement: \($\angle ABC = \angle DBC$\)

Reason: From step 2 and step 3, \($\angle ABC + \angle EBC = \angle DBC + \angle EBC = 180^\circ$\). Thus, \($\angle ABC = \angle DBC$\).

Step 5: Statement: \($\triangle ABE \cong \triangle CBE$\)

Reason: By the angle-angle-side congruence criterion, since \($\angle DBE = \angle EBC$\) (from step 1) and \($\angle ABC = \angle DBC$\) (from step 4), and \($\overline{BE}$\) is common to both triangles.

Step 6: Statement: \($AB = BC$\)

Reason: By step 5, \($\triangle ABE \cong \triangle CBE$\), so corresponding sides are congruent, including \($\overline{AB} \cong \overline{BC}$\).

Therefore, AB is congruent to BC given BE bisects DBC and BE is parallel to AC is proved .

Answer: Save it

Step-by-step explanation:

The angle with (6x-23) and (9x-67) together make a straight line, so their sum is 180:

    (6x-23) + (9x-67) = 180

So you need to solve that for x.

For z, z and (6x-23) are vertical angles, so their angle measures are the same.

    z = 6x-23

\(\\ \sf\bull\dashrightarrow 9x-67+6x-23=180\)

\(\\ \sf\bull\dashrightarrow 9x+6x-67-23=180\)

\(\\ \sf\bull\dashrightarrow 15x-90=180\)

\(\\ \sf\bull\dashrightarrow 15x=180+90=270\)

\(\\ \sf\bull\dashrightarrow x=18\)

Now

\(\\ \sf\bull\dashrightarrow z=6x-23\)

\(\\ \sf\bull\dashrightarrow z=18(6)-23\)

\(\\ \sf\bull\dashrightarrow z=108-23\)
