Answer:
6. The number is 
7. The two numbers are 
and 
Step-by-step explanation:
Question six can be re-worded to create the following expression:
Solve for x to find the number:
Question seven can be solved by first listing the constraints (assuming x is smaller than y):
- x and y are less than 20
To get the numbers, we can create a system of linear equations. First, solve for 
in each expression:
Solve for

Solve for :
The 3 angles form the straight line AB. A straight line equals 180 degrees.
The 3 angles when added together need to equal 180:
2x + 65 + (x + 65) = 180
Simplify by combining like terms:
3x + 130 = 180
Subtract 130 from both sides
3x = 50
Divide both sides by 3
X = 50/3
X = 16 2/3 (16.66667 as a repeating decimal)
Now you have x if you need to solve all the angles replace x with its value and sole:
2x = 2(16 2/3) = 33 1/3
X + 65 = 16 2/3 + 65 = 81 2/3
Answer:
Question 2 the answer is C) y = -3/2x + 2
Question 3 the answer is D) x = 4
Step-by-step explanation:
To solve either we first need to know that parallel lines have the same slope.
So in #2 we know that the new line will also have a slope of -3/2. Therefore, we can use that along with the point given in the problem in point-slope form to get the new equation.
y - y1 = m(x - x1)
y + 1 = -3/2(x - 2)
y + 1 = -3/2x + 3
y = -3/2x + 2
And for #3, we know that we have a vertical line due to the fact that it is expressed as x = a number. Therefore, we must have the same in the answer. D is the only one that has such an answer.
Answer:
the answer is 9 14
Step-by-step explanation:
it's correct so then nine times blah equals 9 / 14
Answer:
Yes.
Step-by-step explanation:
To find the point of intersection we solve the system:
y = x + 3
y = -x + 7 Subtract:
0 = 2x - 4
2x = 4
x = 2.
She is correct.
