Which of these function has a greater rate of change than the function graphed bean why
Marrrta [24]

Answer:

The 2nd option is correct.

i.e.

y = 10+1, because the rate of change of the graphed function is 3.

Step-by-step explanation:

From the graph,

Taking two points

  • (0, 0)
  • (3, 9)

Finding the rate of change or slope between (0, 0) and (3, 9)

Using the formula

Rate of change = Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [9 - 0] / [3 - 0]

               = 9 / 1  

               = 3

Thus, the rate of change or slope of the line = m = 3

The slope-intercept form of the line equation

y = mx+b

where

  • m is the rate of change or slope
  • b is the y-intercept

Considering the function in 2nd option

y = 10x+1

Comparing with the slope-intercept form of the line equation y = mx+b

The rate of change or slope = m = 10

Conclusion:

The rate of change or slope of the graphed line: m = 3

The rate of change or slope of y = 10x+1 is: m = 10

Thus, the rate of change of y = 10x+1 i.e. m = 10 is greater than the rate of change of the graphed line i.e. m = 3.

Hence, the 2nd option is correct.

i.e.

y = 10+1, because the rate of change of the graphed function is 3.

Can someone help me with this question plzzzzz
Ann [662]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

7d + d - 4d - 7 = 5d

8d - 4d - 7 = 5d

4d - 7 = 5d

5d = 4d - 7

Subtract sides 4d

- 4d + 5d =  - 4d + 4d - 7

d =  - 7

Thus the correct answer is Option three.

Michelle borrows a total of $2500 in student loans from two lenders. One charges 4.4% simple interest and the other charges
Inessa [10]

The amount borrowed from the  the lender that charges 4.4% interest is $1000.

The amount borrowed from the  the lender that charges 5.7% interest is $1500.

<h3>What are the linear equations that can be derived from the question?</h3>

a + b = $2500 equation 1

0.088a + 0.114b = $246 equation 2

Where:

a = amount borrowed from the lender that charges 4.4% interest

b =  amount borrowed from the lender that charges 5.7% interest

<h3>How much was borrowed from the lender that charges 5.7% interest?</h3>

Multiply equation 1 by 0.114

0.114a + 0.114b = 285 equation 3

Subtract equation 2 from equation 3

39 = 0.026b

b = $1500

<h3>How much was borrowed from the lender that charges 4.4% interest?</h3>

Substitute for b in equation 1

a + $1500 = $2500

a = $2500 - $1500

a = $1000
