Step-by-step explanation:
Graph is not a function, so B and D are false.
y = 0 is a horizontal line, not a vertical line, so C is false.
This leaves only A.

What is the difference of the polynomials? (9x^2 + 8) = (2x^2 + 3x)?
Answer:
7x^(2) - 3x + 8
Step-by-step explanation:
(9x^(2) + 8) - (2x^(2) + 3x)
distribute the "-" sign.
9x^(2) + 8 - 2x^(2) - 3x
Now combine like terms; (an "x^(2)" goes with an "x^(2)", not with an "x")
9x^(2) - 2x^(2) -3x + 8
7x^(2) - 3x + 8

kilometers to the mountain's peak. How tall is the mountain?
Answer:
4.3068
Step-by-step explanation:
so what you do is 1.48 x 2.91
Answer:
= 4.39km
Step-by-step explanation:
Camp distance = 1.48Km
Distance travelled afterwards = 2.91km
Mountain Height = total distance travelled
So total distance = 1.48 + 2.91
= 4.39km -----------> final answer

A mixture of paint calls for 1/3 cups of red paint and 3/4 cups of yellow paint. If there were 4 cups of red paint added to the mixture, how many cups of yellow paint would need to be added to keep a constant rate of proportionality? (Hint: You can use your answer from the first question to help you solve this!)
Answer:
9 cups of yellow paint
Step-by-step explanation:
A mixture of paint calls for 1/3 cups of red paint and 3/4 cups of yellow paint.
From the above question
1/3 cups of red paint = 3/4 cups of yellow paint
1 cup of red paint = x cups of yellow paint
Cross Multiply
1/3 × x = 3/4 × 1
x = 3/4 ÷ 1/3
x = 3/4 × 3/1
x = 9/4
x = 2 1/4 cups of yellow paint
Hence, 1 cups of red paint requires 2 1/4 cups of yellow paint
If there were 4 cups of red paint added to the mixture, how many cups of yellow paint would need to be added to keep a constant rate of proportionality?
1 cups of red paint = 2 1/4 cups of yellow paint
4 cups of red paint = x cups of yellow paint
Cross Multiply
x cups of yellow paint = 4 × 2 1/4 cups of yellow paint
= 4 × 9/4 cups of yellow paint
= 9 cups of yellow paint
Therefore, 4 cups of red paint requires 9 cups of yellow paint
2 4/5 divided by 2 1/5 plz answer corectly ps this is mixed number ones
Answer:
The correct answer is 1.27.
Step-by-step explanation:
Step 1: Turn the mixed numbers into improper fractions.
2 4/5 = 14/5
2 1/5 = 11/5
Step 2: Turn the improper fractions into decimals.
14/5 = 2.8
11/5 = 2.2
Step 3: Divide the fractions.
2.8 ÷ 2.2 = 1.27 when rounded to the nearest hundred.
Hope this helps! :D

A rock is thrown from the top of a ladder. The function
h(t) = –16t2 + 120t + 10 gives the height of the rock t seconds after it is
thrown a certain number of feet.
What is the height of the rock at 5 seconds?
Answer:
h'(t)=88
Step-by-step explanation:
h'(t)=d/dt (-16t x 2 + 120t + 10
h'(t)=d/dt (-32t + 120t + 10)
h'(t)=d/dt (88t + 10)
h'(t)=d/dt (88t) + d/dt (10)
h'(t)=88 + 0

Step-by-step explanation:
Step 1: Define
4h = 92
Step 2: Solve for h
Divide both sides by 4: h = 23Step 3: Check
Plug in h into the original equation to verify it's a solution.
Substitute in h: 4(23) = 92Multiply: 92 = 92Here we see that 92 does indeed equal 92.
∴ h = 23 is the solution to the equation.
