Answer:

y = 11/5x + 64/5

Step-by-step explanation:

Slope=(4 - - 7)/(-4 - - 9) = (4+7)/-4+9)

= 11/5

y-intercept: -7-(11/5)(-9)

= -7 - - 99/5

= - 7 + 99/5 = (-7*57+99/5)

= 64/5

Which statement is true about the function f(x)= √x?
AlexFokin [52]

Answer:

The range of the graph is all real numbers greater than or equal to 0.

Step-by-step explanation:

we have

y=\sqrt{x}

using a graphing tool

The graph in the attached figure

step 1

Find the domain

we know that the radicand of the function must be greater than or equal to zero

so

The domain is the interval ------> [0,∞)

x\geq0

All real numbers greater than or equal to zero

step 2

Find the range

The range is the interval -----> [0,∞)

y\geq0

All real numbers greater than or equal to zero

Wewaii [24]

Answer:

Step-by-step explanation:

Given that

The generator rents for 6 hours and the total cost is $48

And, for another job The generator rents for 4 hours and the total cost is $40

We need to find out the hourly rates

For the first one

= $48 ÷ 6 hours

= $8

For the second one

= $40 ÷ 4 hours

= $10

Hence, the hourly rates are $8 and $10 respectively

Write an equation of the line and interpret the slope ​
Bess [88]

Answer:

Step-by-step explanation:

Slope of this line will be= m= (600-200)/(1-5)

m = 400/-4 = -100

Eq of line will be:

(y-y1)=m(x-x1)

y-200=-100(x-5)

y-200+100x-500=0

100x+y-700 = 0

To write equation in slope-intercept form

y=mx+c

just seperate "y"

y=-100x+700
