The graph of a function is shown:
Answer:
D) {-2, 1, 2, 5}
Step-by-step explanation:
The "output" of a function will never be an ordered pair, so we can immediately eliminate options A and B.
In this case, the output refers to the y-values of the function.
Since the ordered pairs are: (-2, 5), (-1, 1), (2, -2), and (5, 2), we see that the output of this function is: 5, 1, -2, 2.
Thus, choice D is correct.

Answer:
a = 6
Step-by-step explanation:
120 = 3 + 3(7a - 3) (by PEDMAS, expand parentheses first by distributive property)
120 = 3 + 7a(3) - 3(3)
120 = 3 + 21a - 9
120 = 21a - 6 (add 6 to both sides and rearrange)
21a = 120 + 6
21a = 126 (divide both sides by 21)
a = 126/21
a = 6
Step-by-step explanation:
120-(3+3*(7*a-3))=0
Step by step solution :
STEP

:
Equation at the end of step 1
120 - (3 + 3 • (7a - 3)) = 0

Pulling out like terms :
3.1 Pull out like factors :
126 - 21a = -21 • (a - 6)
Equation at the end of step

:
-21 • (a - 6) = 0
STEP
4
:
Equations which are never true:
4.1 Solve : -21 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : a-6 = 0
Add 6 to both sides of the equation :
a = 6
One solution was found :
a = 6
3. Your neighbor has a large tree on his property, and he's worried that the next serious storm will knock the tree onto his house. However, tree removal is an
expensive service. Since your neighbor's budget is limited, you offer to help him determine how high the tree is. If the distance from the house to the tree is
greater than the height of the tree, then the house should be avoid damage should the tree ever fall.
Answer:
ok we dont know the height of the tree

The Salinas brothers, Juan and Carlos, have collected pledges for a bike rally they plan to have to raise money for their boy scout troop. Carlos's pledges total $11.50/mi and Juan's pledges total $9.75/mi. Carlos can peddle 10 mi/hr and Juan can peddle 12 mi/hr. If they plan to start and stop at the same time, how many hours will they have to bike if they want to raise at least $1000 together?
Answer:
5 hours
Step-by-step explanation:
Given that :
Juan:
Rate = 12mi/hr
$9.75/mi
Carlos :
Rate = 10mi/hr
$11.50/mi
To raise atleast $1000 altogether :
Let number of hours = h
Distance = rate * time
[(12*h) * 9.75] + [(10*h) * 11.50] ≥ 1000
[117h + 105h] ≥ 1000
222h ≥ 1000
h ≥ 1000/222
h ≥ 4.504
To earn atleast $1000 altogether, they must work for atleast 5 hours (nearest whole number).
what is the measure of the missing angle?
Answer:
137 degrees
Step-by-step explanation:
By using the fact that a triangle contains 180 degrees and angles made by the same lines are congruent we can find out that the top angle in the first triangle is 45 degrees. We can then figure out that the missing angle in that same triangle is 75 degrees by adding 45 and 60 and subtracting that from 180. Then we add that 75 degrees to 68 degrees to get 143 degrees which we can use to discover that the corner of the triangle that connects to the other triangle is 37 degrees. From there we know that triangles contain 180 degrees, so the remaining value is 43 and with this we can discover that the value of the asked for angle is 137 degrees.

Answer:
x=-2
Step-by-step explanation
1) Remove () and Rewrite
13x+13+2x=1/2x2(5x-7)2) Collect Like Terms
15x+13=5x-73) Move Terms
15x-5x=-7-134) Divide Both Sides
10x=-20ANSWER IS x=-2
Answer:
0=−20
Step-by-step explanation:
Distribute
Combine like terms
Combine multiplied terms into a single fraction
Multiply by 1
Subtract from both sides of the equation
Two straight lines have equations y = p x + 4 y = p x + 4 and p y = q x − 7 p y = q x − 7 , where p p and q q are constants. The two lines meet at the point ( 3 , 1 ) ( 3 , 1 ) . What is the value of q q ?
Answer:
q = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
The point of intersection (3, 1 ) is the solution to both equations
Using
y = qx - 7 and substituting x = 3, y = 1
1 = 3q - 7 ( add 7 to both sides )
8 = 3q ( divide both sides by 3 )
[tex]\frac{8}{3}[/tex] = q
Write 14 more then a number (pre algebra)
Answer:
x + 14
Step-by-step explanation:
Let's break it down to key terms:
14
more (+)
a number (x)
So 14 more than a number is just adding 14 to x.
x + 14

If x=3m-4 and y=6-m, which of the following expresses y in terms of x
Answer:
What you want to do is solve for m in whichever equation it's easier to so in, then substitute that in to the other equation. For instance:
X=3m-4
Y=6-m
Solve the 2nd equation to get m=6-y
Plug that into the first equation to get x=3(6-y)-4
X=18-3y-4
X-14=-3y
14-x=3y
Y=(14-x)/3

What is the value of x in the equation below
6(x-8)=72
Answer:
x = 20
Step-by-step explanation:
6(x-8)=72
6x-48=72
6x-48+48=72+48
6x=120
6x/6=120/6
x = 20
hope it's helpful ❤❤❤❤❤❤
THANK YOU.
#
Answer: x=20
Step-by-step explanation:
Distribute the 6 to the values in the parentheses
6x - 48 = 72
Add 48 to each side
6x = 120
Divide each side by 6
x = 20
)Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:
Year Lawn Care Fee
2000 $750
2010 $1350
A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.
Answer:
Rate of change = (1350 - 750)/(2010 - 2000) = 600/10 = $60
Initial value = $750
Equation is y = 60x + 750; where y is the amount charged to customer and x is the number of years from 2000.

takes 16 what??
if u tell me i can help u x
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
If there are 4 floors and each classroom takes 1/6 of a floor, there are 6 classrooms per floor. Then, since there are 4 floors, you do 6 classrooms X 4 floors, which equals 24 classrooms.

What transformation is this?
Answer:
Translation (x, y) → (x + 5, y + 7)Step-by-step explanation:
It seems the translation:
(x, y) → (x + 5, y + 7)R(-4, -1) → R'(-4 +5 = 1, -1 +7 = 6)
S(-6, 3) → S'(-6 + 5 = -1, 3+7 = 10)
help meee will give brainly! Find the domain of the function f(x)=5x−9 .
DONT SAY I DONT KNOW
Answer and Step-by-step explanation:
[tex]\frac{5}{x-9}[/tex]
The domain is all real numbers except 9 (positive)
This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.
