Answer:
x= -7 and y=37
Step-by-step explanation:
substitute y=-26-9x in -2x-y=12
-2x-(-26-9x)=12
-2x+26+9x=12
-2x+9x=12-26
7x= -14
x= -14/2
x= -7
substitute x=-7 in y=26-9x
y= -26-9x
y= -26-9(-7)
y= -26+63
y=37
x= -7 and y=37

subtract (3x+5)-(x+2).
Answers
First, subtract “x” from “3x” to get 2x. Then, subtract 5-2. You should end up with an answer of 2x+3!
= (3x + 5) - 1 (x + 2) *we will be distributing -1 to x and 2.
= 3x + 5 - x - 2
= 3x - x + 5 - 2 (we have combined like terms)
= 2x + 3
So, in conclusion, the answer and expression for this problem is: 2x + 3.

Answer:
15x^2-14x-4
Step-by-step explanation:
(8x^2 * x-7x+2)+(7x^2 -7x-6)
you take out the parentheses
you add the common ones so -7x+-7x= -14x
8x^2 +7x^2 = 15x^2
and 2-6= -4
so in total it's 15x^2-14x-4
Answer: 11x^2 -16x-3
Step-by-step explanation:
Solution:
Your problem → (8x^2-7x+2) + (3x^2-9x-5)
(8x2-7x+2)+(3x2-9x-5)
=8x2-7x+2+3x2-9x-5

Answers
Answer:
x=0 y=-11 (0,-11)
Step-by-step explanation:
1. take what y equals (3x-11) and plug it in for y in the second equation
Should look like this: O= 6x-2(3x-11)-22
2. Then distribute O=6x-6x+22-22
3. Then combine like terms O= 0 the 22's cancel out as well as the x's
x= 0
4. plug 0 in for x in the first equation y=3(0)-11
5. y= -11
6. x=0 y=-11 (0,-11)
The value of a computer decreases with its age, until it is worth nothing. A computer that was purchased new (age 0 years) for

After type your answer.
years the computer will be worth nothing.
Answers
Answer:
v(x)=2200-N*110
the value of computer after 8 years is 1320
Step-by-step explanation:
at 0 years the value is 2200
after 6 years the value is 1540
we should calculate how much the value of the computer decreases in one year , so we can do an interpolation to determine the value of the computer after 1 year and it is 2090$ . so, 2200-2090=110$ that means in one year the value of computer decreases 110$ so the function is v(x)=2200-n*110
where n is number of years
so after 8 years : v(8)=2200-8*110=1320$

4.5 is 7.5% of what number?
Answers
Answer:
60
Step-by-step explanation:
The required number is 60.
What is percent?In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now the given expression is,
4.5 is 7.5%
Let x be the number.
Therefore, 7.5% of x is 4.5
⇒ 7.5% of x = 4.5
⇒ 7.5% * x = 4.5
⇒ 7.5/100* x = 4.5
⇒0.075 x = 4.5
Dividing both side by 0.075 we get,
x = 4.5 / 0.075
Solving we get,
x = 60
this is the required number.
Thus,the required number is 60.

Anybody know how to do these two? (Geometry) free Brainliest and points !!
Answers
Answer:
1) 80
2) 58
Step-by-step explanation:
180 - 112 = 68
180 - 68 + 32 = angle 2
180 - (63 + 59) = angle 1
Answer: The first one is 80, the second one is 58
Step-by-step explanation: a triangle adds up to 180. For the first one, you first find the degree for the last corner (the one that is not marked). Than angle would be 64, a straight line is 180 degrees, subtract that by 112 to get 64. Then you add this angle with 32, getting 100. Then subtract that by 180 and you'll get 80 as the answer. For the second one, just add the two numbers up and subtract that by 180.
