Let X = the number of yards he needs to mow.

Each yard he gets $25, so you would multiply 25 by x to find the total amount he makes.

Now you have 25x.

He needs at least $400 total.

At least means the amount can either equal 400 or be greater than 400.

This would make the inequality:

25X ≥ 400

Now to solve, divide both sides by 25:

25x ≥ 400 =

x ≥ 400 / 25

x ≥ 16

He needs to mow at least 16 yards.

Which number line represents the solution to the inequality x - 3 > 2

Ivahew [28]

Answer: x > 5

Step-by-step explanation: To solve for <em>x</em> in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.

Since 3 is being subtracted from x, we add 3 to

both sides of the inequality to get x > 5.

When graphing x > 5, we have an open circle on 5 and the

open circle tells us that 5 is not part of our answer.

Then we draw an arrow going to the right to represent

all possible solutions to this inequality, any number greater than 5.

PLEASE HELP!! Write an equation of g(x) that represents an exponential base “e” parent function with the following transformatio

Montano1993 [528]

Answer:

$g(x) = 12 {e}^{ - x - 7}$

Step-by-step explanation:

The parent function is

$g(x) = e {}^{x}$

First it is asked to reflect over the y axis so using the rule

$g(x) = g( - x)$

Our function looks like

$g(x) = e {}^{ - x}$

Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule

$g(x) = g(x - h)$

When subtracting a 7 it looks like now

where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule

$g(x) = a \times g(x)$

where a is the vertical stretch. So now it would look like

$g(x) = 12 {e}^{ - x - 7}$

A certain corporation listed their sales in 100s as 20700. What was their actual volume in millions?

Mariana [72]

Answer: Their actual volume in millions is 207×10⁹.

Step-by-step explanation:

Since we have given that

A certain corporation listed their sales in 100s as 20700

We need to find their actual volume in millions,

According to question,

In 100s, their volume = 2070000

In 100000, their volume is given by

$207\times 10^5\\\\=2070000\times 10^5=207\times 10^9$

Hence, their actual volume in millions is 207×10⁹.

Tyshawn took a taxi from his house to the airport. The taxi company charged a pick-

Elza [17]

3.5m + 2.5 = 79.5 is the equation that could be used to determine m, the number of miles in the taxi ride.

Given in question,

Pick-up fee = $2.50

Fee per mile = $3.50

Total fare = $79.50

Let the no. of miles = m

Fee for m miles = 3.50m

Equation, 3.50m + 2.50 = 79.50.

Hence, the equation is 3.50m + 2.50 = 79.50.

Hayley has 272 beads.she buys 38 more beads. She will use 89 beads to make bracelets and the rest to make necklaces. She will us

STALIN [3.7K]

First, do 272 + 38 = 310
Secondly, do 310 - 89 = 231
Third, do 231 ÷ 9 = 25

The most number of beeds she can have is 25
