Answer: F(2)=23

Step-by-step explanation:

Answer:

23

Step-by-step explanation:

f(x)= 4(2)^2 +7

f(x)= 4(4) +7

f(x)= 16+7

f(x) = 23

Answer:

1. 7x

2. x+15

3. 18/x

Step-by-step explanation:

Assume the number is x because we don’t know what it is.

1. Product means multiplication so x * 7 equals 7x.

2. More means addition so x+15.

3. This one is easy. 18 divided by x = 18/x

Answer:

8

Step-by-step explanation:

In order to find the length and width necessary to find area, we need to look at the chart. By exmaining, we can see that the length is two units from top-to-bottom. We can also see that the width is 4 units from left-to-right. We can now multiply 4 times 2 to get our answer of 8.

Answer:

B. 8.0

Step-by-step explanation:

To figure out the area you just do length times width, and you find the two by counting the amount of squares they take up. The length is two, and the width is 4; therefore the area is 8

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Since those two angles are corresponding that means they are equal to each other so we write an equation like this...

[tex]7x+9=8x+2[/tex]

Now we solve for x...

[tex]7x+9=8x+2\\9=x+2\\x=7[/tex]

And that's it x will equal 7.

Answer:

You are simply dividing a by 3 to reach y each time!

Step-by-step explanation:

The required equation is y = -(3/2)x + 3 in slope-intercept form.

A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.

For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.

The equation is given in the question, as follows:

12x + 8y = 24

Isolate the variable of y for the above equation,

8y = - 12x + 24

Divided both sides by 8 into the equation,

y = - (12x)/8 + (24)/8

y = -(3/2)x + 3

This equation is in slope-intercept form.

Step-by-step explanation:

First,, we should subtract the vacation price from her savings to get the base. That is 1835-1540=295. Then we can do 295/65,, and then we get 4  7/13. So,, she can only afford 4 weeks of these deductions in order to have enough money for her vacation.

Answer:8

Step-by-step explanation:

Area = Length x Width.

simple room measurement

Measure the length using the distance from one wall to the opposite wall.

Measure the width from wall to wall.

Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.

Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.

Repeat this process for each room.

Answer:

- 17/10

Step-by-step explanation:

Answer:

29 and 31

Step-by-step explanation:

Let

x = the first odd number

x + 2 = the second odd number

seven times the smaller number is 17 more than six times the larger

7*x = 17 + 6(x + 2)

7x = 17 + 6x + 12

Collect like terms

7x - 6x = 29

x = 29

x + 2 = 29 + 2

= 31

Check:

7*x = 17 + 6(x + 2)

7*29 = 17 + 6(29 + 2)

203 = 17 + 6(31)

203 = 17 + 186

203 = 203

Therefore, the two consecutive odd numbers are 29 and 31

Answer: B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]

Step-by-step explanation:

you need to get B alone so that would be subtracting everything around it

ab = -c + d

then you need to get that a away from it by dividing both sides by A

B = [tex]\frac{-c}{a}[/tex] + [tex]\frac{d}{a}[/tex]
