Answer:
C
Step-by-step explanation:
time is directly proportional to the number of problems in the set
=> x = ky
k = constant of proportionality
when k = 12
x = 12y
by making y the subject, we divide both sides by 12
=> y = x/12
)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.
If 2x - 3 = 3x - 7, what is the value of x?
Answer:
x=4
Step-by-step explanation:
2x-3=3x-7
Subtract 2x from both sides of the equation
-3=x-7Add 7 to both sides of the equation to isolate x

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.

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.

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.
A cube of length 7 cm is painted on all its faces. What is the total surface area of the
painted surfaces?
Answer:
294
Step-by-step explanation:
To find the surface area of a cube, first we need to realize that a cube, on its surface, is made up of 6 squares forming a box. That means that all we need to do is find the surface area of one of those squares, and multiply it by 6. So what we do is take side length 7, and square it, giving us 49. Then, we multiply that by 6 giving us 294. The formula for this, in short, is y=6a^2, y being the total surface area and a being a side length, in this case 7.

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

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.

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).

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
