Consider the following expression 3(4+1)(2y+5). Select all of the true statements below.

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

8

Step-by-step explanation:

5+3=8

Arithmetic

-3-2=5

because

-3-2

=

-3 + -2

3 negatives + 2 negatives = 5 negatives

-3/4+1 1/4 = 1/2

3/4 - 2 1/2 = 3/4 - 10/4 = -7/4 = -1 3/4

-9+6= -3

8 - 4 = 4

-1.5+1.9 = .4

Answer:

A.) -3/4 + 11/4 = 2

-3/4 = -0.75

11/4 = 2.75

-0.75 + 2.75 = 2

B.) 3/4 + (-21/2) = -9.75

-21/2 = -10.5

3/4 = 0.75

-10.5 + 0.75 = -9.75

C.) -9 + 6 = -3

D.) 8 + (-4) = 4

E.) -1.5 + 1.9 = 0.4

Answer:

second answer: y = 5x + 120; $180

Step-by-step explanation:

he starts with $120.

so, whatever else he does per month, there will always be the $120 starting amount to be added.

so, the third and the fourth answers are out.

then think : $5 every month.

that is how much after 2 months ? 2×5 = $10.

how much after 3 months ? 3×5 = $15.

so it has to be an equation that contains 5x (5 times the number of months).

combining both thoughts :

y = 5x + 120

now let's use x = 12 (for 12 months = 1 year).

5×12 + 120 = 60 + 120 = $180.

yes, it is that simple. no hidden "hocus pocus" is needed. just common sense.

1) Last year, Maria spent $2093.75. Here's the equation to find that answer:

(a ÷ b) × c

(15,000 ÷ 24) × 3.35

2) Same equation. (15,000 ÷ 32) × 3.35. The answer of this equation is 1570.3125, but that rounds to $1570.31.

3) This part represents a simple difference/subtraction problem. Since she spent $2093.75 last year, and will spend $1570.31 with a new car, she will save 523.44.

4) Using percent of change, the percent decrease Maria will realize in one year is 33.333%, or \(\frac{1}{3}\).

1) 2093.75

2) 1570.31

3) 523.44

4) 33.333%

Answer: 2,369.25 cm3

Step-by-step explanation:

Hi, to answer this question we have to use proportions:

X has volume of 64 cm3 and s surface area of 208 cm2

The proportion is = volume / surface area = 64/208

Y has volume of 729 cm3

Volume / surface area = 729/ s (surface area of y)

64/208 = 729/ s

Solving for s:

s = 729 / (64/208)

s = 2,369.25 cm3

Answer:

r = 1

Step-by-step explanation:

The equation is,

→ 6r - 1 + 6r = 11

Now the value of r will be,

→ 6r - 1 + 6r = 11

→ 12r = 11 + 1

→ r = 12/12

→ [ r = 1 ]

Hence, the value of r is 1.
