Multiply. Your answer should be a monomial in standard form. (-b7)(7b4) =​

Step-by-step explanation:

a. For any function, in order for a vertical stretch to happen, a must be greater than 1 so the answer to a is

a>1.

b. For b, the graph will compress when a is between 0 and 1 but not equal to both.

So the answer to. b is

0<a<1.

c.A vertical stretch happens when a>1, a horinzontal compression also happens when a>1, if you confused let me explain

Consider the graph above. Let say we have a quadratic function

[tex](x - 3) {}^{2} [/tex]

Let that be the parent function, if we stretch the function, a must be greater than 1 as we established in a.

In the fist picture, let say a=2.7

The function is stretched in the vertical direction

Now, let say if we affect x.

Here, let a=2.7 we know have

The function is being compressed when a>1, so that means that

we stretched vertically or compressed horizontally when a>1. It depends on the location of a. If a is outside the parenthesis, we will stretch by a factor of a. If a is I side the parenthesis, we will compress by a factor of a.

d. A must be negative or a<0

Answer:

3/10,  8.9%,  0.113,  3/10,  5/16

Step-by-step explanation:

we can change each one to a percent to make it easier:

0.113 = 11.3%

8.9%

5/16 = 0.3125 = 31.25%

0.03 = 3%

3/10 = 30/100 = 30%

Least to Greatest:

3/10,  8.9%,  0.113,  3/10,  5/16

Answer:

250%

Step-by-step explanation:

an easy way for doing this is look at the 1/2 part because 1 divided by 2 is 0.5 yo move the decimal 2 spaces to the right and you have 050 which is 50 and then you just add the 2 in front of the 50 and you have 250 which in this case is 250%

Answer:

40%

Step-by-step explanation:

Percent markup = new price - original price/original price

Do the subtraction first.

58.80 - 42.00 = 16.80

Now do the division

16.8/42 = 0.40

Change the decimal to a percent by moving the decimal two place to the right.

0.40 = 40%

Answer:

.065

Step-by-step explanation:

6 1/2 %

=6.5%

=.065

When changing a percent to a decimal, move the decimal point two places to the left.

OR,

percent means per hundred.

(6 1/2)/100

= (13/2)/100

= 13/2 × 1/100

= 13/200

= .065

OR

6 1/2 %

= 6.5/100

=.065

The missing data values of the linear function are: B. missing x: 0 missing y:1

The equation, y = mx + b represents a linear function, where m is the slope and b is the y-intercept of the function.

Find the slope using two given pairs of points from the table, (-9, 3) and (-6, 2):

Slope (m) = change in y/change in x = (3 - 2)/(-9 -(-6))

Slope (m) = 1/-3 = -1/3.

Find b by substituting (x, y) = (-9, 3) and m = -1/3 into y = mx + b:

3 = -1/3(-9) + b

3 = 3 + b

3 - 3 = b

0 = b

b = 0

Plug in m = -1/3 and b = 0 into y = mx + b

y = -1/3x

Use the equation to find the missing data values:

When y = 0, x would be:

0 = -1/3x

x = 0

When x = -3, y would be:

y = -1/3(-3)

y = 1

The missing data values are: B. missing x: 0 missing y:1

let's recall that d = rt, distance = rate * time.

we know that Steve is twice as fast as Jill, so say if Jill has a speed or rate of "r", then Steve is traveling at 2r fast, now we know they both in opposite directions have covered a total of 120 miles, so if Jill covered "d" miles then Steve covered 120 -d, check the picture below.

Answer:

2141.7 gallons of regular gasoline were sold

1771.7 gallons of premium gasoline were sold

Step-by-step explanation:

in this question you need to make two equations one for total price and the other for total gallons. assume R is for gallons of regular gasoline and P is for gallons of premium gasoline sold.

[tex]3.3R +3.45P=15733.5[/tex]

[tex]P = R-370[/tex]

then substitute one of them at the other:

[tex]3.3R +3.45(R-370)=15733.5[/tex]

by solving the equation R = 2520

substitute R in equation P = R-370:

P = 2520-370 = 2150

A 2155 gallons of premium gasoline and 2525 gallons of regular gasoline were sold.

Let's use a system of equations to solve this problem.

Let:

R = Number of gallons of regular gasoline sold

P = Number of gallons of premium gasoline sold

given the following information:

Regular gasoline price: $3.30 per gallon

Premium gasoline price: $3.45 per gallon

Total sales: $15,733.50

Relationship between regular and premium sales: R = P + 370

create two equations based on the information:

Sales equation: 3.30R + 3.45P = 15733.50

Relationship equation: R = P + 370

Now substitute the second equation into the first equation:

3.30(P + 370) + 3.45P = 15733.50

Distribute and solve for P:

3.30P + 1221 + 3.45P = 15733.50

6.75P = 14512.50

P = 2155

Now that we know P,  find R using the relationship equation:

R = P + 370

R = 2155 + 370

R = 2525
