Answer:

C

Step-by-step explanation:

Put the equation in the form y = mx + b where m is the slope and b is the y-intercept

First, find the slope by doing the change in y divided by the change in x for the two points. This would be [tex]\frac{2-(-3)}{0 - 20} = -\frac{5}{20} = -\frac{1}{4}[/tex]. m = -1/4 in the equation.

So far, the equation is y = -1/4x + b

This means the slope is -1/4. Since it give you the y intecept, (0, 2), you know that b is 2 and the equation would be C. y = -1/4x + 2

Answer:

85%

Step-by-step explanation:

21.25 divided by 25 gives you 0.85, which is 85%

Answer:

slope is the rise over run. so for the first one you have to go up 1 and over 3 then plot the point. the y intercept is the point on the vertical line. so you should then have two points the one on the vertical line and the rise over run.

Answer:

Step-by-step explanation:

6.

if the slope is 8 , y-intercept is 2

use the general equation for slope intercept y= mx+b where m is slope and b is y-intercept

y= 8x +2

7.

slope is 0, y- intercept  is -3

y= 0*x -3  the equation is y= -3

8. (same steps for 9)

slope is 5, and (2,7) on the line

use the point slope equation (y-y1) = m( x-x1)

y-7 = 5 (x-2)

now transform it into the slope intercept form y= mx+b

y = 5x - 10 + 7; y = 5x -3

5.

between the points (0, -2) and ( 2, 0 ) the slope is m = (y2-y1)/(x2-x1) =(-2-0)/(0-2) = 1, and the y-intercept is -2

y= 1*x -2 ; y=x-2

13.

a. y= 18x +10 because the distance y is 18 for each x hour plus the extra 10 miles that she had at the start

b. the y-intercept is where the graph intersects the y-axis so is 10 and represents the starting point at 10 miles , and the slope is 18 and represents how fast is moving

c. after 2 hours means x=2

y= 18*2 +10 = 36+10 = 46 miles

Step-by-step explanation:

1.0835 ≅ 1.84

The digit in the 4th place is 5 (greater than equal to 5). Therefore, we add 1 to the previous digit 3.

Round off 1.0835 at Thousandths (3 decimal place) = 1.84

Answer:

4.662 feet

55.944 inches

Step-by-step explanation:

Pablo's height = 1.11 x 4 feet = 4.44  feet

Michaela's height = 1.05 x 4.44feet = 4.662 feet

1 foot = 12 inches

To convert 4.662 to inches, multiply by 12

4.662 x 12 = 55.944 inches

Answer:

$280

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 2800 × 0.02 × 5 = 280

I = $ 280.00

The simple interest accumulated

on a principal of $ 2,800.00

at a rate of 2% per year

for 5 years is $ 280.00.

The simple interest earned on a deposit of $2,800 that earns 2% annual interest after 5 years is $280

An interest is the amount of money gained by investing in a business.

The simple interest is gotten using the formula:

I = PRT

Where I is the interest, P is the principal, R is the rate, T is the time.

Given that P = $2800, r = 2% = 0.02, T = 5 years, hence:

I = PRT

I = 2800 * 0.02 * 5 = $280

The simple interest earned on a deposit of $2,800 that earns 2% annual interest after 5 years is $280

Answer:

Reflection over both y and x axes

Step-by-step explanation:

So we can see that all points have become their negative. If this only applied to x coordinates, this would have been a relfection over the y axis. If it only applied to x, it would be a reflection over the x. But since it applies to both, the answer is that it was a reflection over both axes.

Answer: 1:3

Step-by-step explanation: for 4 toads you have 12 frogs so the ratio is 4 to 12. But you can simplif, divide each side by 4 so it’s 1 to 3

The ratio is 1: 3.

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in proportion to the other. The dividend or number being divided is referred to as the antecedent, and the divisor or number that is dividing is referred to as the consequent. A ratio compares two numbers via division.

Given that, Mr. Boylan collected 12 frogs for every 4 toads he found. so the ratio of toads to frogs will be 4: 12. which can be further noted down as 1: 3

Therefore for every toad, Mr. Boylan collected 3 frogs.
