Answer:

x = -1 when h(x) = -4

Step-by-step explanation:

Solve for x when h(x)= -4

h(x) = -3x - 7

-3x - 7 = -4

     +7    +7

-3x = 3

divide -3 by 3

-3x/3 = 3/-3

x = -1

You can check this by plugging the -1 into x

-3x - 7

-3(-1) - 7

3 - 7 = -4

Answer:

x=−3x−7whatish(−4)

Step 1: Flip the equation.

28ah2istw−3x=x

Step 2: Add 3x to both sides.

28ah2istw−3x+3x=x+3x

28ah2istw=4x

Step 3: Divide both sides by 28h^2istw.

28ah2istw

28h2istw

=

4x

28h2istw

a=

x

7h2istw

Answer:

a=x7h2istw

The volume of a sphere is 5,000pi m3. What is the surface area of the sphere to the nearest square meter?
lyudmila [28]
To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =  \frac{4}{3}π r³
5000πm³ = \frac{4}{3} π r³
5000m³ = \frac{4}{3} r³
5000m³ x 3 = 4r³
\frac{15000m³}{4} = \frac{4r³}{4}<span>
</span>∛3750 = ∛r³

r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²

(please explain each step) <br><br>Find the m&lt;QRP if m&lt;PRS=35° and m&lt;QRS=85°  
iragen [17]
You have to find x (QRP), so just subtract the entire angle(QRS) with the given angle (PRS) to get your missing angle(QRP).

Hope this helps.

6 out of 10 students completed their homework. What is the ratio of students who did not do their homework to those who did?
ludmilkaskok [199]

Answer:

2/3 or 2:3

Step-by-step explanation:

If 6 out of 10 students completed the homework then 4 out of 10 students did not complete the homework.

So the answer is 4/6 but we are not done yet.

The 4 comes from people who didn't do it and the 6 comes from people who did.

Since its asking the ratio of students who did not do their homework to those who did the 4 comes first.

As I said we are not done yet since we have to simplify.

4/6=2/3

So the answer is 2/3 or 2:3
