Answer:

12.5% (I think)

Step-by-step explanation:

75 is the amount of money lost, and 75 is 12.5 percent of 600

Answer:

12.5 percent decrease

Step-by-step explanation:

Use the formula

new-old/old

525 is new price being sold

600 is old price being sold

525-600

-75/600

-1/8

-1/8= -0.125

0.125= 12.5 percent

so 12.5 percent decrease.

Answer:

-10/3 or -3 and 1/3

Step-by-step explanation:

you can do y1-y2 over x1-x2 of two points

or you can count the rise oiver run from (5,-5) to (2,5) which is 10/3

but its negative slope cause your going back 3 to the left

Answer:

No!!

Step-by-step explanation:

For every 1 pound it costs $2⁵⁰

For every 2 pounds it costs $5⁰⁰

For every 3 pounds it costs $7⁵⁰

and so on going by 2.50 each pound.

Answer:

67.5

Step-by-step explanation:

ok easy it cost $90

90/100=0.9

0.9*25=22.5

90-22.5

67.5

Thats insane tho!

Answer:

Please check the explanation.

Step-by-step explanation:

Part a)

Finding the slope of f(x)

Given the table of the function f(x)

x        f(x)

-1        -5

0        -1

1          3

Finding the slope using the formula

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)[/tex]

[tex]m=\frac{-1-\left(-5\right)}{0-\left(-1\right)}[/tex]

[tex]m=4[/tex]

Thus, the slope of the function f(x) = 4

Finding the slope of g(x)

We know the slope-intercept form of a linear function is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

Given the function

[tex]g(x) = 2x-7[/tex]

comparing with the slope-intercept form

y = mx+b

The slope of the function g(x) = 2

Thus, we conclude that:

Hence, the slope of f(x) is greater.

Part b)

Finding the y-intercept form of f(x)

We know that the y-intercept can be determined by setting x = 0 and determining the corresponding y-value.

From the table,

It is clear at x = 0, y = -1

Hence, the y-intercept of the function f(x) = -1

Finding the y-intercept form of g(x)

Given the function

[tex]g(x) = 2x - 7[/tex]

comparing with the slope-intercept form (y = mx+b)

[tex]y = mx+b[/tex]    

where b is the y-intercept

Hence, the y-intercept of g(x) = b = -7

Thus, we conclude that:

Hence, the y-intercept of f(x) is greater.

Answer:

$9.60

Step-by-step explanation:

0.40(6/0.25)

0.40(24)

9.6

Answer:

the correct answer is $2.40

Step-by-step explanation:

0.40= every 0.25miles

for 6 miles it will be 2.40 because u multiply 6 with 0.40 and u get the answer

Answer:

y=5x+12

Step-by-step explanation:

Starting with the components of slope intercept form y=mx+b

m is you rate of change and b represents your y intercept

This would give you in your case y=5x+b, but we still need to solve for b.

So given your (x,y) point you plug it into y=5x+b giving you:

-3 = 5 (-3) + b

then some easy multiplication and addition

-3 = -15 + b

get the constant on the oppisite side of your variable b

-3 + 15 = -15 + 15 + b

This results in b = 12

Now rewrite the formula with b = 12

Which TADA! gives you

y = 5x + 12

Answer:

A. 29

Step-by-step explanation:

Set 5x - 11 = to 3x + 5, and then solve for X, and substitute the x value (8) back into the equation to get 29.
