Answer:
y = x^2 + 14x + 62
Step-by-step explanation:
y = (x + 7)^2 + 13 is to be rewritten in the form y = ax^2 + bx + c.
Note: Use " ^ " to denote exponentiation.
Expand y = (x + 7)^2, holding the constant term to be added on later:
y = x^2 + 14x + 49 + 13
Combining the constants, we get:
y = x^2 + 14x + 62 (which matches Answer D).

Answer:
The equation 7h=63 can be used to find how many hours h a person needs to work to earn $63 at $7 per hour. How many hours does a person need to work to earn $63?
Step-by-step explanation:
The equation 7h=63 can be used to find how many hours h a person needs to work to earn $63 at $7 per hour. How many hours does a person need to work to earn $63?
Answer:
9 hours
Step-by-step explanation:
7h=63
divide both sides by 7 to get 9
7h/7=h
63/7=9
h=9
A bag contains 42 red, 45 green, 20
yellow, and 32 purple candies. You
pick one candy at random. Find the
probability that it is green or yellow.
Answer:
65/139 fraction form
0.47 decimal form
Answer:
Step-by-step explanation:
Total sample space , n (s) = 139
no of green candies , n (g) = 45
no. of yellow candies , n (y) = 20
Probability that is green or yellow is
P( g or y) = P(g) + P(y)
= n(g) / n(s) + n (y) / n(s)
= 45 / 139 + 20 / 139
= 65 / 139
hope it will help :)

It angle relationship and show work??
Answer:
m<x=146
Step-by-step explanation:
its a supplementary angle, meaning both angles add up to 180.

Step-by-step explanation:
How far up the house would a ladder be resting if it is 25 ft long and 3 ft
away from the house? Round to the nearest tenth if necessary.
5.3 ft
21 ft
24.8 ft
25.2 ft
Answer:
C
Step-by-step explanation:
The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.
Givens
a = 3
b = ?
c = 25 feet
Formula
a^2 + b^2 = c^2
Solution
3^2 + b^2 = 25^2
9 + b^2 = 625 Subtract 9 from both sides.
b^2 = 625 - 9
b^2 = 616 Take the square root of both sides.
b = sqrt(616)
b = 24.8

Step-by-step explanation:
Carla e Ana foram tomar sorvete e gastaram r$ 23,00 dividido a conta em partes iguais, quanto cada uma pagou ? Gente me explica como faz a conta não só resposta por favor
Answer:
each of them has to pay $11.5 individually
Step-by-step explanation:
The computation of the amount paid by each one is shown below:
As carla and Ana gone for an icecream and the bill is $23 that should be divided equally
So here the carla should pay
= $23 ÷ 2
= 11.5
And, Ana should pay
= $23 ÷ 2
= $11.5
Hence, each of them has to pay $11.5 individually
