Write an equation of the parabola that passes through the point (62,−490) and has x-intercepts −8 and 72. Then find the average rate of change from x=−8 to x=2.
Answer:
y = 0.7(x^2 - 64x - 576)
Average rate of change = -49.
Step-by-step explanation:
As the x intercepts are -8 and 72 we can write the equation
y = a(x + 8)(x - 72) where a is some constant to be found.
As it passes through point (62, -490) we have, substituting:
-490 = a(62+8)(62-72)
-490 = - 700a
a = 0.7
So the equation of the parabola
y = 0.7(x + 8)(x - 72) or
y = 0.7(x^2 - 64x - 576).
Average rate of change between x = -8 and x = 2
= [0.7(2+ 8)(2 - 72) - 0.7(-8+8)(-8-72)] / (2 - -8)
= -490 - 0 /10
= -49

Mrs. Phillips bought 1.5 pounds of ground beef from Kroger. She paid a total of $6.75 for the ground beef. What was the price per pound?
Answer:
Price per pound is $4.50
Step-by-step explanation:
Price per pound = $6.75 / 1.5lb = $4.50/lb
Answer:
Price per pound of ground beef is $4.5
Step-by-step explanation:
Price of 1.5 pounds of ground beef = $6.75
We need to find price per pound of ground beef.
Solving:
For finding cost of 1 pound of apples, we will divide cost of 1.5 pounds of ground beef by 1.5. i.e
Price of 1.5 pounds of ground beef = $6.75
Price of 1 pounds of ground beef = $6.75/1,5
= $ 4.5
So, price per pound of ground beef is $4.5

4. Elena's account balance with her parents is
-$5.50. She adds a certain amount of
money to her balance by mowing the lawn.
Elena now has an account balance less than
$20. Determine a possible amount she
earned mowing the lawn. Then interpret the
solution. (Example 1) moll end to bi
Answer:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Step-by-step explanation:
Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.
Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.
All they give us is that Elena has less than $20 in her bank account.
So your answer may look like this:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Elena earned, amount more than -$5.50 and less than $20 by mowing the lawn.
What is Inequality?If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.
For example, x>3 (x should be greater than 3)
Given,
Account balance of Elena with her parents = -$5.50.
Which means she is in debt of $5.50.
Elena then adds a certain amount of money to her balance by mowing the lawn,
which may have paid off her debt, that is not sure.
But,
Account balance of Elena after mowing the lawn is more than - $5.50 less than $20.
Let the money Elena earned by Elena earned mowing the lawn = x
Then,
Possible amount she earned mowing the lawn = -$5.50 < x <$20.
Hence, Possible amount Elena earned mowing the lawn is
between -$5.50 and $20 = -$5.50 < x < 20.

Answer:
74
Step-by-step explanation:
did school asignment
The measurement of ∠ B = 74°
What are Supplementary angles?Two Angles are Supplementary when they add up to 180 degrees.
Given that ∠ A and ∠ B are Supplementary and ∠ A = (3x−23),
∠ B = (2x−12)
According to definition of Supplementary,
∠ A + ∠ B = 180°
(3x−23) + (2x−12) = 180°
5x - 35 = 180°
5x = 180° + 35
5x = 215°
x = 43°
Putting x = 43° in ∠ B = (2x−12)
∠ B = (2*43−12)
∠ B = 86 - 12
∠ B = 74°
Hence, The measurement of ∠ B = 74°
