Step-by-step explanation:

So visually youre given the function

for h(-4) it can also be written as h(-4) = y

<em>what</em><em> </em><em>do</em><em> </em><em>you</em><em> </em><em>get</em><em> </em><em>for</em><em> </em><em>y</em><em> </em><em>when</em><em> </em><em>you</em><em> </em><em>substitute</em><em> </em><em>-</em><em> </em><em>4</em><em> </em><em>for</em><em> </em><em>x</em><em>?</em><em> </em>

All you have to do is trace the line until you get to x=-4 and then find the y that corresponds to it (looks like around y= - 1)

for the other one h(x) = - 5

<em>what</em><em> </em><em>do</em><em> </em><em>you</em><em> </em><em>get</em><em> </em><em>for</em><em> </em><em>x</em><em> </em><em>when</em><em> </em><em>you</em><em> </em><em>substitute</em><em> </em><em>-</em><em> </em><em>5</em><em> </em><em>for</em><em> </em><em>y</em><em>?</em><em> </em>

what you do is similar, trace the line along the y-axis and see what x-value you get for y =-5

Answer:

3 and x = 0

Step-by-step explanation:

To find the value of h(- 4)

Locate x = - 4 on the x- axis, go vertically up to meet the graph at (- 4, 3 )

Then the value of h(- 4) = 3

For h(x) = - 5

Locate y = - 5 on the y- axis. This is the point (0, - 5)

then the value of x for which h(x) = - 5 is x = 0

The larger of two numbers is five more than twice the smaller number. The sum of the two numbers is 38. Find the numbers.
White raven [17]

Answer:

11 and 16

Step-by-step explanation:

A good way to solve these is to work backwards.

X= larger and Y= smaller

if X is 5 more than 2Y than subtract 5 from the total

38 - 5 = 33

divide by 3

33/3 = 11

11 = Y and double that is 22 so add the five back into X and you get 16

A soundproofing tile is made of 8 identical solid right pyramids with square bases. The length of the whole tile shown is x inch
mylen [45]

Answer:

Option B ⇒ Area of base of each pyramid :

(\frac{x}{4})^2 in^2

Option A ⇒ Volume of pyramid :

\frac{1}{3} x^{2} \cdot y   cm3

Step-by-step explanation:

One side of tile consists of 4 pyramids and since length of whole tile is x,

So, the base length of each pyramid = \frac{x}{4}

⇒ Area of base of each pyramid = side²

⇒ Area =

(\frac{x}{4})^2 in^2

Volume of square based pyramid :

=(Area of base )\cdot \frac{h}{3}\\=\frac{x^2}{3} cm^3

For 1. The correct Option is B

For 2. The correct option is A
