Answer:
when x=-3 y=10
when x=0 y=4
when x=3 y=-2
Step-by-step explanation:
all you have to do is plug in -3 0 and 3 for x
-2(-3)=6
6+4=10 so when x=-3 y=10
-2(0)=0
0+4=4
so when x=0 y=4
-2(3)=-6
-6+4=-2
so when x=3 y=-2

Answer:
Perimeter = 54
Step-by-step explanation:
Since AC = RP, then the following also applies:
AB = RB
CB = PB
So, in order to determine this, you first need to find a common ratio in order to find the missing side of PB which you need for the perimeter.
To determine the ratio you do the following:
AB = 21 (14 + 7)
RB = 7
21: 7 = 3: 1
This means in finding a smaller side you can divide by the value 3 to find it.
It also means that side CP is 2/3 of the value of CB which means that we need 1/3 of the value left in order to determine PB:
CP = 10 = 2/3, which means 1/3 is 5, so
PB = 5
Therefore: CB = 15
Perimeter = CB + AC + AB
15 + 21 + 18 = 54

What is the area of the following circle?
Either enter an exact answer in terms of T or use 3.14 for it and enter your answer as a decimal.
d = 8
Step-by-step explanation:
The area of the circle is 50.24 square units. To get the area of the circle you have to multiply π × r². When doing the conversion it would be Area = 3.14 × 4 × 4 = 50.24
how to change decimals to percentages
You move the decimal point over 2 spots to the right.
For example, the value 0.03 becomes 3%
Another example: 0.789 turns into 78.9%
Moving the decimal over 2 spots to the right is the same as multiplying by 100

Answer:
F=90
D=37
E=53
f=18.3
d=11
e=14.6
Step-by-step explanation:
Triangle Sum Theorem means 180-37-90=E. So, E=53 degrees.
Sin(37)=[tex]\frac{11}{f}[/tex]
fsin(37)=11
f=[tex]\frac{11}{sin(37)}[/tex]
f=18.3
Tan(37)=[tex]\frac{11}{e}[/tex]
etan(37)=11
e=[tex]\frac{11}{tan37}[/tex]
e=14.6

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of −0.91 is calculated. What would this imply about the football team winning at home?
A The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
B The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.
C The scatter plot would not be represented by a line of best fit with a negative slope.
There is a weak correlation between the football team playing at home and winning.
D There is no causation and almost no correlation between the football team playing at home and winning.
Using correlation coefficients, it is found that the correct option is:
B The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.It also is the slope of the line of best fit.In this problem, the correlation coefficient of −0.91, meaning that there is a strong inverse relation between the location of the game and the team's winning percentage, that is, the team is more likely to win on the road, hence, option B is correct.

Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
Answer:
(2, 0 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 4 → (1)
3x - 7y = 6 → (2)
Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x
6x + 9y = 12 → (3)
- 6x + 14y = - 12 → (4)
Add (3) and (4) term by term to eliminate x
0 + 23y = 0
23y = 0
y = 0
Substitute y = 0 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(0) = 4
2x = 4 ( divide both sides by 2 )
x = 2
solution is (2, 0 )

increase a length of 24m so that the ratio of the new length to the old length is 11:8.
Answer:
33m
Step-by-step explanation:
If the ratio of the new length to the old length is 11:8 (simplified ratio)
I like to set up a proportion, like this,
x/24 = 11/8, where x is the undefined new length
x*8 = 24*11 (cross multiply)
8x = 264 (multiply)
x = 33 (divide 8 by both sides)
The new length is 33m.
Hope I helped! Good Luck!
Answer:
33m
Step-by-step explanation:
The 8 part of the ratio refers to the old length 24m
Divide by 8 to find the value of one part of the ratio
24m ÷ 8 = 3m ← value of 1 part of the ratio, then
11 parts = 11 × 3 = 33m
Thus
33m : 24m = 11 : 8

Answer:
1. 144 2. 16 3. 1 4. 3x-6
Step-by-step explanation:
So think of this as a function in a function. So you work from the inside to the outside. So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).
Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]
so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)
So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144

Answer:. 38 and 52
It is given here that
angle FKY = 90.
we know angle. FKG + GKY. = FKY
so,. (7c + 24) + (5c + 42) = 90
12c + 66 = 90
12c = 90 - 66
12c = 24
c= 24/12
c = 2
then angle is
7*2+24 = 38
5*2 + 42 = 52
