What is the rate of change in y per unit change in x for this linear function?
A. -5
B. -2.5
C. -2
D. -0.4
Answers
B. -2.5
Step-by-step explanation:
This is asking for gradient. Pick any two points (x, y) then calculate the y change ÷ x change. example, (0, -5) and (-2, 0). with [0-(-5) ÷ -2-0] you get -2.5

What is the slope in the equation:
y = 3/2x + 32
Answers
Answer:
3/2
Step-by-step explanation:
Answer:
3/2
Step-by-step explanation:
To find the slope of a line given the equation of the line, first write it in slope-intercept form. Use inverse operations to solve for y so that it is written as y=mx+b. Then you can easily see the slope since it is the coefficient of the x variable, or the number in front of x.
)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.
Answers
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.

Answers
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.

What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
Given the coordinates of G are (2,-4), now if the point is translated 6 units to the left and 3 units up. The new coordinates of G' are:
G' = (2-6, -4+3)
G' = (-4, -1)
Hence, the coordinates of G' are (-4,-1).

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?
Answers
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).

-2(x-3)+4x = -(-x+1) SOLVE EQUATION AND SHOW STEPS ...NEED ANSWER NOW
Answers
Answer:
x=-7
Step-by-step explanation:
-2(x−3)+4x=−(−x+1)
Step 1: Simplify both sides of the equation.
−2(x−3)+4x=−(−x+1)
−2)(x)+(−2)(−3)+4x=x+−1(Distribute)
−2x+6+4x=x+−1
(−2x+4x)+(6)=x−1(Combine Like Terms)
2x+6=x−1
2x+6=x−1
Step 2: Subtract x from both sides.
2x+6−x=x−1−x
x+6=−1
Step 3: Subtract 6 from both sides.
x+6−6=−1−6
x=-7
