Answer:
There is no solution I think. I am probably wrong...
Step-by-step explanation:
y=-2x+8
y=x-1
Solve y=-2x+8 for y
Substitute -2x+8 for y in y =x-1
y=x-1
-2x+8=x-1
Add -x to both sides
-2x+8+-x=x-1+-x
-3x+8=1
Add -8 to both sides
-3x+8+-8=1+-8
-3x=-9
Divide both sides by -3
-3x/-3=-9/-3
x=3
Substitute 3 for x in y =-2x+8
y=-2x+8
y=(-2)(3)+8
Simplify both sides of the equation
y=2
Answer : y=2 and x=3

I hope that's help !
Answer:
15 + 5w ≥ 75
Step-by-step explanation:
Let the number of weeks be represented as w.
We are told from the question that:
Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn.
The word "at least" in mathematics means equal to or greater than and it is represented by the sign ≥
Therefore, our inequality equation is written as:
15 + 5w ≥ 75
Your equation is 3(8-4)+2*5.5
you want to follow PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtaction
so first you will solve the parenthesis (8-4) = 4
put it into your exquation
3(4)+2*5.5
now the next thing we have is multiplication
3(4) = 12
2*5.5 = 11
now plug it into the equation
12+11=?
now you just do the addition
your answer should be
A. 23
The answers to the questions are as follows:
- The value of the empty box in the diagram is 10
- The probability that the number is in AnB = 1/5
<h3>How to solve the Venn diagram</h3>
We have E = {1, 3,5, 7, 9, 11, 13, 15, 17, 19}
A= { 3, 7, 9, 11, 15}
B = {5, 7, 11, 13}
We have A n B = numbers that are contained in both of the sets
= 7, 11
a.) We have to count the total number in the dataset. That is the total number of odd numbers that are less than 20.
Hence total numbers in the set = 10
b. The probability that the number is in set AnB
= 7, 11
= 2/10
= 1/5
We can conclude that the probability that the number is in A intersect B = 1/5
