Hannah factored the expression 24xy + 15y. Her work is shown below. 1. GCF (24xy, 15y) = 3y 2. 24xy/3 = 8xy, 15y/3 = 5y 3. 3(24x

y + 15y) What are the errors in Hannah's work? Check all that apply. She divided by 3 instead of the GCF. She found the wrong GCF. She divided wrongly. She didn't complete step 4 and use the distributive property to be sure the expressions are equivalent. She didn't undistribute the GCF from the original expression.

Marc mows lawns for $25 each lawn, plus $5 for every hour he spends mowing. The equation for his total earnings per lawn is y =
Mila [183]

Answer:

<h2>The flat pay $25 represents the intercept</h2>

Step-by-step explanation:

To answer this question we need to first understand and compare it with the equation of straight line.

i.e y= mx+c  which is the equation of line

where m= slope

           y= dependent variable

           x= independent variable

          c= intercept

Given

y= 25+5h

comparing both expression we can see that

25 corresponds to c which is the intercept

Four brothers each bought two hotdogs and a bag of chips at the concession stand.if the bag of chips was $1.25,and the total was
ahrayia [7]

Answer:

  $1.65

Step-by-step explanation:

The total purchase can be described by ...

  4(2h +1.25) = 18.20 . . . . where h is the price of a hot dog

  8h = 13.20 . . . . . . . . . . . subtract 5.00

  h = 1.65 . . . . . divide by 8

The price of a hot dog was $1.65.

A pebble is tossed into the air from the top of a cliff. The height, in feet, of the pebble over time is modeled by the equation
Charra [1.4K]

Answer:

96

Step-by-step explanation:

The maximum height reached by the pebble modeled by the quadratic function,

h(t)=-16t^2+32t+80, can be found by finding the vertex.

Let's first find the t-coordinate of the vertex . The max height will correspond to this value of t which means we have to find the h(t)-coordinate.

When comparing h to at^2+bt+c, we see that:

a=-16

b=32

c=80

We need to evaluate the following to find the t-coordinate of the vertex:

t=\frac{-b}{2a}

t=\frac{-32}{2(-16)}

t=\frac{-32}{-32}

t=1

So now to find the correspond h(t)-coordinate, we will need to replace t in -16t^2+32t+80 with 1:

-16(1)^2+32(1)+80

-16(1)+32+80

-16+32+80

16+80

DanielleElmas [232]
Well, 9 billion = 9,000,000,000 so in scientific form it would be 9 x 10^9 To get the exponent, just count the number of zeros, which for 9 billion we have 9
