Answer:
y = -½x + 3
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + c
where m is the gradient (slope) and c is the y-intercept
We can find the gradient and intercept from the two points on the diagram
The points are:
(0, 3) and (4, 1)
The y-intercept is when x = 0
we are already given this point so
c = 3
now we can use our other point to find m. So:
1 = 4m + 3
-2 = 4m
-½ = m
Now we can put both variables into our slope-intercept form
y = -½x + 3

1 175
2 175
3 225
4 275
The domain is 1,2,3,4 it would be from 1 to 4 if the electrician bills for partial hours, or greater than 4, but this is not in the chart.
The range is 175,225,275. Again there could be other values in between or greater than 275, but it is not in the chart.
Step-by-step explanation: It is a function because for each x-value there is only one y-value, even if the y-value is the same for two of the x-valus
Every day, you buy your lunch for $4 at school. How much money will you spend if you buy your lunch from Monday through Friday for three weeks?
Answer:
She would spend $60
Step-by-step explanation:
First you would multiply 5 and 4 ,because there are five days in a week, to get $20. Next you would multiply 20 by 3, because you want to know the total of three weeks, and you would get $60.

5.) Consider a square with side lengths x.
Write an equation for the perimeter p of the square, then rearrange the equation to make x the subject
Answer:
The perimeter p of the square is:
[tex]p=4x[/tex]
And in terms of x:
[tex]\displaystyle x = \frac{1}{4}p[/tex]
Step-by-step explanation:
Part A)
We are given a square with side lengths x.
Recall that all four sides of a square are equivalent. Therefore, our perimeter is:
[tex]\displaystyle \begin{aligned} p & = x + x + x + x \\ \\ & = 4x\end{aligned}[/tex]
Part B)
To make x the subject of the equation, divide:
[tex]\displaystyle \begin{aligned} p & = 4x \\ \\ x & = \frac{p}{4} \end{aligned}[/tex]

Given the following formula, solve for r c=2rr
Answer:
[tex] \sqrt{ \frac{c}{2} } = r[/tex]
Step-by-step explanation:
c=2rr
c = 2r×r
c= 2r²
c/2= r²
[tex] \sqrt{ \frac{c}{2} } = \sqrt{ {r}^{2} } \\ \\ \sqrt{ \frac{c}{2} } = r[/tex]
Can two planes contain the same point
Answer:
SOLUTION: Postulate 2.5 states if two points lie in a plane, then the entire line containing those points lies in that plane. Therefore, the statement is always true. ... The intersection of two planes can be a point. SOLUTION: Postulate 2.7 states if two planes intersect, then their intersection is a line.

Please graph and table -4x+2y=-8
Answer:
x=1/2y+2
Step-by-step explanation:
−4x+2y=−8
Step 1: Add -2y to both sides.
−4x+2y+−2y=−8+−2y
−4x=−2y−8
Step 2: Divide both sides by -4.
−4x

Step-by-step explanation:
A manufacturer of game controllers is concerned that their controller may be difficult for left handed users. They set out to find lefties to test. About 13% of the population is left handed. If they select a sample of five customers at random in their stores, what is the probability of each of the following outcomes?
a. The first lefty is the fifth person chosen
b. There are some lefties among the 5 people
c. The first lefty is the second or third person
d. There are exactly 3 lefties in the group
e. There are at least 3 lefties in the group
f. There are no more than 3 lefties in the group
Answer:
a)0.074
b)0.502
c)0.2114
d)0.0166
e)0.01790
f)0.9987
Step-by-step explanation:
Probability of being left handed = 0.13
Probability of being not left handed = 1-0.13 =0.87
They select a sample of five customers at random in their stores
a. The first lefty is the fifth person chosen
Probability that first lefty is the fifth person chosen =[tex]0.87 \times 0.87 \times 0.87 \times 0.87 \times 0.13=0.074[/tex]
b)There are some lefties among the 5 people=[tex]1-P(x=0)=1-0.87^5=0.502[/tex]
c)The first lefty is the second or third person=[tex]0.87 \times 0.13 + 0.87 \times 0.87 \times 0.13 =0.2114[/tex]
d)
[tex]P(x=3)=^5C_3 (0.13)^3 (0.87)^2=\frac{5!}{3!2!}(0.13)^3 (0.87)^2=0.0166[/tex]
e)
[tex]P(x\geq 3)=P(x=3)+P(x=4)+P(x=5)\\P(x\geq 3)=\frac{5!}{3!2!}(0.13)^3 (0.87)^2+\frac{5!}{4!1!}(0.13)^4(0.87)^1+\frac{5!}{5!0!}(0.13)^5 (0.87)^0=0.01790[/tex]
f)
[tex]P(x\leq 3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)[/tex]
[tex]P(x\leq 3)=\frac{5!}{0!5!}(0.13)^0 (0.87)^5+\frac{5!}{4!1!}(0.13)^1(0.87)^4+\frac{5!}{2!3!}(0.13)^2 (0.87)^3+\frac{5!}{2!3!}(0.13)^3 (0.87)^2=0.9987[/tex]

Answer:
f(x) = x * -3
Step-by-step explanation:
so, you have x and you have f(x), as you can see -4 turns into 12... you basically have to divide, multiply, add or subtract for each value to see what they have in common, here it's easy since -4 * -3 is 12, -2 * -3 is 6, 0 * -3 is 0, etc etc. hope it helped : )

9. A company is looking to hire a painter. One painter states that their fee can be determined by
using the expression 50x + 100 where x is the number of hours it takes to paint. A second painter
states that their fees can be determined by using the expression 40x + 125. The company wants
to know when the fee would be the same for each painter. What number of hours makes the
equation 50x + 100 = 40x + 150 true?
