What is an equation of the line that passes through the points (-7, -5) and
(-7, -2)?

Answer:

\(y = \dfrac{1}{2}x -5\)

Step-by-step explanation:

The slope intercept form of a linear equation is
y = mx + b

where m = slope and b = y-intercept

Since these are given, simply plug in to get

\(y = \dfrac{1}{2}x -5\)

Answer:

V = 27

Step-by-step explanation:

62 = −19 + 3v

Swap sides so that all variable terms are on the left-hand side.

−19 + 3v = 62

Add 19 to both sides.

3v = 62 + 19

Add 62 and 19 to get 81.

3v = 81

Divide both sides by 3.

v = 81/3

​Divide 81 by 3 to get 27.

v = 27

Answer: \(y = -\frac{1}{2} x -8\)

Step-by-step explanation:

Going to build the equation in slope-intercept form, let me know if you need another form :)

Slope intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Simply plug in the slope for m to get: y = -1/2x + b.

Then simply plug in the point to get:

-6 = -1/2(-4) + b

-6 = 2 + b

b = -8

y = -1/2x -8

Hope it helps :)

Answer:

y=2/3

Step-by-step explanation:

2y+4y=6-3y

⇔ 2y+4y+3y=6

⇔ 9y=6

⇔ y=6/9=2/3

The answer is:

y = 2/3

Work/explanation:

For now, I focus on the left side and combine the like terms:

\(\bf{2y+4y=6-3y}\)

\(\bf{6y=6-3y}\)

Add 3y to each side

\(\bf{6y+3y=6}\)

Combine like terms

\(\bf{9y=6}\)

Divide each side by 9

\(\bf{y=\dfrac{6}{9}}\)

\(\bf{y=\dfrac{2}{3}}\)

Hence, the answer is 2/3.

Answer:

Step-by-step explanation:

You want the coordinates of the vertices of QRST after it has been translated right 2 units, then reflected across the y-axis. The original coordinates are Q(1, 5), R(3, -1), S(0, 0), T(-2, 3).

The problem statement is written as a composition of the transformations Ry and T(2,0). A composition of functions is generally executed right to left, meaning the translation will be done first, then the reflection.

The numbers in the translation vector are added to the coordinates:

  (x, y) ⇒ (x+2, y+0)

Reflection over the y-axis changes the sign of the x-coordinate:

  (x, y) ⇒ (-x, y)

Then the composition of transformations is ...

  (x, y) ⇒ (-(x+2), y)

  Q(1, 5) ⇒ Q'(-3, 5)

  R(3, -1) ⇒ R'(-5, -1)

  S(0, 0) ⇒ S'(-2, 0)

  T(-2, 3) ⇒ T'(0, 3)

ANSWER:

B. (8 * 4) + (2 * 4) + 2

STEP-BY-STEP EXPLANATION:

We have the following expression

If we operate this expression we can know which one it is equivalent to, therefore we would have:

Therefore the correct answer is option B.

Answer:

Step-by-step explanation:

(-1,7), (0,5), (1,3)

and

(0,-3), (2,5), (4,13)

Step 1: Isolate the Sin Operator

\(8 sin(\frac{\pi }{6} x)=2\\sin(\frac{\pi }{6} x)=0.25\\\\\)

Step 2: Use Inverse Sin(arcsin) to isolate the term with the x variable

Note that since trig functions have 2 general solutions, this will give us one of our general solutions.

\(x=\frac{6 arcsin(0.25)}{\pi } =0.48\)

x₁= 0.48

Solving for x₂

Use the period identity for Sin Functions

\(sin(x)=sin(\pi -x)\)

X in this case is arcsin(0.25)

\(\frac{\pi }{6} x=\pi -arcsin(0.25) = 5.52\)

So our two general solutions are 0.48 and 5.52

Step 3: Period

Trig Functions have periodic behavior and this function period is

\(\frac{2\pi }{1} (\frac{6}{\pi } )= 12\)

So our general solutions are

0.48±12k, where k is an integer

5.52±12k, where k is an integer

Let k=1, and we get our next set of solutions:

12.48 and 17.52

So our answer is 0.48,5.52,12.48,17.52

The sine ratio of angle θ is 4/5 because sin is the ratio to opposite to the hypotenuse.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

We have a right angle triangle showing in a picture.

As we know, the sin is the ratio to opposite to the hypotenuse.

Sinθ = 4/5

Thus, the sine ratio of angle θ is 4/5 because sin is the ratio to opposite to the hypotenuse.

Answer:

The coordinates of the point are (-4.5,-1).

Step-by-step explanation:

We want to find point T(x,y).

I am going to say that out points are A(-8,-2) and B(6,2)

Since it partitions the segment in a 1:3 ratio, we have that:.

\(T - A = \frac{1}{1+3}(B-A)\)

\(T - A = \frac{1}{4}(B-A)\)

We apply this to both the x-coordinate and y-coordinate of T.

x-coordinate:

x-coordinate of A: -8

x-coordinate of B: 6

x-coordinate of T: x.

So

\(T - A = \frac{1}{4}(B-A)\)

\(x - (-8) = \frac{1}{4}(6-(-8))\)

\(x + 8 = \frac{14}{4}\)

\(x = \frac{14}{4} - 8\)

\(x = \frac{14}{4} - \frac{32}{4}\)

\(x = -\frac{18}{4}\)

\(x = -4.5\)

y-coordinate:

y-coordinate of A: -2

y-coordinate of B: 2

y-coordinate of T: y.

\(T - A = \frac{1}{4}(B-A)\)

\(y - (-2) = \frac{1}{4}(2-(-2))\)

\(y + 2 = 1\)

\(y = -1\)

The coordinates of the point are (-4.5,-1).

Answer

1.5/4

Step-by-step explanation:

Based on the information, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.

It should be noted that to prove the commutativity of the logical connectives ∧ (conjunction) and ∨ (disjunction), we need to show that they satisfy the commutative property

From the truth table, both P ∧ Q and Q ∧ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∧ Q ≡ Q ∧ P, and ∧ (conjunction) is commutative.

In order to prove P ∨ Q ≡ Q ∨ P, we construct a truth table for both expressions. Both P ∨ Q and Q ∨ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∨ Q ≡ Q ∨ P, and ∨ (disjunction) is commutative.

Hence, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.

Here, we are required to judge Gary's calculation as portrayed in the question above.

Gary's calculation is correct according to the calculation.

Ultimately, 48.026/6.49 = 7.4.

The question asks that 48.026 is divided by 6.49.

By first considering the whole numbers on the left hand side of the decimal point in each number,

We can conclude that 48 divided by 6 equals 8, i.e 48/6=8.

However, the calculation becomes much easier by shifting the decimal points in both numbers two spaces to the right as indicated in the diagram (i.e multiply both numbers by 100).

This leaves us with 4802.6 to be divided by 649.

Dividing 4802.6 by 649 yields 7 with a remainder of 259.6 (this is so because 7 × 649 = 4543).

259.6 can have it's decimal point shifted one space right to yield 2596.

And, 2596/649 = 4.

The condition above is hypothetical, and there's a need for the decimal point to be shifted one space back to the left, which leaves us with 0.4.

Ultimately, 48.026/6.49 = 7.4.

Therefore, Gary's calculation is correct using the work shown in the question above.

The difference in volume between the two boxes would be = 156in³

To calculate the difference in volume between the boxes is the find the individual volume of the boxes using the formula ;

Volume = length×width×height.

For box 1 = length = 12in, width = 7¾in, height= 2in

Vol = 12×7¾×2 = 186in³

For box 2; length = 3⅔in, width = 3½in, height= 2⅓in

Volume = 3⅔×3½×2⅓ = 30

You want the sequence of steps to solve the system of equations by substitution.

To solve the system by substitution, the first step is writing an expression for one of the variables. Here, the x-variable has a coefficient of 1 in the second equation, so that is a good place to start for getting an expression for x.

Additional comment

It is also convenient to subtract the first equation from the second to solve this system by "elimination".

  (x -2y) -(-7x -2y) = (11) -(-13)   ⇒   8x = 24   ⇒   x = 3

Then the second equation can be used to find y:

  3 -2y = 11   ⇒   -2y = 8   ⇒   y = -4
