Answer: A>7

Step-by-step explanation:

Answer:

y= -3x + 5

Step-by-step explanation:

negative reciprocial of the slope:

m=1/3

m=-3

Subsitube the point (1,2) into y=mx+b with new slope and solve for b:

y=mx+b

2=-3(1)+b

b=5

Equation:

y=-3x+5

Answer:102.22

Step-by-step explanation:

Answer:

2.22%

Step-by-step explanation:

Recall that year 1, the base year, has a CPI of 100.

From question 1, we know that the CPI of year 2 is 102.22.

To find the rate of inflation, find the percent change from year 1 to year 2:

102.22-100= 0.0222, or 2.22%

Step-by-step explanation:

Answer: 2509.8 i think that is the correct answer

Step-by-step explanation:

Answer:

y=3/4x-2

a=(8/3,0)

b=(0,-2)

m=3/4

Step-by-step explanation:

STEP 1

3x-4y =8 substract 3x from both sides

-4y=-3x+8 divide -4 to everything

y=3/4x-2

STEP 2

substitute 0 for y and solve for a (x-intercept)

Answer:

Step-by-step explanation:

the 2 shaded rows on the top are both 10 and the bottom shaded row is 5 so the equation would be 2×10+5

Answer:

0.25

Step-by-step explanation:

The model represents one whole number (1)

Each square represents .01 of the whole number.

So if you add all the shaded squares together, you would get 25 shaded, which means the answer would be 0.25

Answer:

2 1 ÷ 2

Step-by-step explanation:

Given that

The kitchen of Amita would be a rectangular area contains 3 and 3 ÷ 4 square meters

And, the width of her kitchen is 1 and 1 ÷ 2 meter

So based on the above information, the length of Amita kitchen is

Here you divide the rectangular area by the width

= (3 and 3 ÷ 4) ÷ (1 and 1 ÷ 2)

= 2 and 1 ÷ 2

Hence, the  length in meters of Anita's kitchen is  2 and  1 ÷ 2

Answer:

30,240 ways

Step-by-step explanation:

This question is bothered on permutation. Permutation has to do with arrangement.

If there are 10 computers and 5 students, the number of ways students will sit at the computers if no computer has more than one student can be expressed as;

10P5 = 10!/(10-5)!

10P5 = 10!/(5)!

10P5 = 10*9*8*7*6*5!/5!

10P5 = 10*9*8*7*6

10P5 = 30,240

Hence the number of ways is 30,240 ways

Answer:

[tex] y = \frac{3}{4}x - \frac{1}{4} [/tex]

Step-by-step explanation:

First, find the slope using the points (3, 2) and (-1, -1):

Slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - 2}{-1 - 3} = \frac{-3}{-4} = \frac{3}{4} [/tex]

Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.

-1 = ¾(-1) + b

-1 = -¾ + b

Add ¾ to both sides

-1 + ¾ = b

(-4 + 3)/4 = b

-¼ = b

Substitute m = ¾ and b = -¼ in y = mx + b.

The equation would be:

✅[tex] y = \frac{3}{4}x - \frac{1}{4} [/tex]

Answer:

-1,6<-4/3<2/3<4/5<0.9

Step-by-step explanation:

Answer:

12.5

Step-by-step explanation:

The 20 lbs on the left side time the 5 feet is equal to 100.

You need the weight on the right side to equal 100 when it is multiplied to it's length from the fulcrum, which is 8.

All you need to do is divide 100 by 8, to get 12.5.

The amount of interest earned by Jason is $78.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.

Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.

Given that Jason invests $325 in a bank account. The bank has an annual interest rate of 24%.

The interest will be calculated as:-

SI = ( P x R x T ) / 100

SI = ( 325 x 24 x 1 ) 100

SI = $78

Hence, the simple interest is $78.
