solve for x. please?
Help please. Solve the system of equations using substitution. Show your work in the workspace provided below.
y=3x - 11
O=6x-2y-22
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)
Cassie wants to mount an 18 cm x 18 cm square picture on a square board that is four times the area of the picture.
What is the area of the picture?
What is the area of the board?
What are the dimensions of the board?
9514 1404 393
Answer:
picture: 324 square cmboard: 1296 square cmboard dimensions: 36 cm squareStep-by-step explanation:
a) The area of the picture is the product of its dimensions:
(18 cm)² = 324 cm²
__
b) The area of the board is 4 times that:
board area = 4×324 cm² = 1296 cm²
__
c) The dimensions of the square board are the square root of its area:
√1296 = √(4×324) = (√4)(√324) = 2×18 = 36 . . . . cm
The board is 36 cm square.

What is the surface area of the square pyramid represented by the net below?
A: 48 cm
B: 96 cm
C: 64 cm
D: 112 cm
Answer: C: 64 cm
Step-by-step explanation:
The square has a a side of 4 centimeter meaning the area would be 16 cm. The area of the triangle is determined by half of the area of the base times the height. This mean that 4 x 6 = 24 and then 24/2 = 12. 4 x 12 = 48 (due to four triangles). 48 + 16 = 64. It is C: 64 cm

express x^2 -8x+5 in the form (x-a)^2 -b where a and b are integers
Answer:
(x - 4)² - 11
Step-by-step explanation:
Given
x² - 8x + 5
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
= x² + 2(- 4)x + 16 - 16 + 5
= (x - 4)² - 11
Anybody know how to do these two? (Geometry) free Brainliest and points !!
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.
Nathan bikes every 2 days and swims every 5 days. He started biking on October 2nd and started biking on October 5th. On what day will he bike and swim on the same day. Here are the options for the answers: October 4th, October 8th, October 10th, October 12th, 15th, or 20th.
PLEASE HELP!!
Answer:
October 10, hope this helps.
Step-by-step explanation:
If Nathan started biking on October 2nd, and he started swimming on October 5th, then since October 10 is the closest day to them that he will be swimming and biking, but also because their both even numbers so he will be biking and swimming on October 10th.
multiply: (x+a)^2-(x-b)^2+x^2+(a-b)x-ab by (a+b)
Answer:
Step-by-step explanation:
Step-by-step explanation:the answer is =−a2b2y−ab3y+a2+3ax−b2+bx+x2 how did i get answer:Distribute:
=a2+2ax+x2+−b2+2bx+−x2+x2+(a)(x)+(−b)(x)+−a2b2y+−ab3y
=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y
Combine Like Terms:
=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y
=(−a2b2y)+(−ab3y)+(a2)+(2ax+ax)+(−b2)+(2bx+−bx)+(x2+−x2+x2)
=−a2b2y+−ab3y+a2+3ax+−b2+bx+x2

David lost 15 dollars from his pocket. Write a signed number to represent this change.
Answer:
-$15
Step-by-step explanation:
Here, we want to write a singles number that can represent this change
From the question, there is a loss of 15 dollars
When something is loss, it is negative

-15
Step-by-step explanation:
Find the slope between of (-17,11) and (4,11)
Answer:
y=11
Step-by-step explanation:
The y is the same which means they're on the same line. Tell me if I'm wrong.
Do not solve the system below. Its solution is (x, y)
= (1, 1). Instead, answer the questions.
3x + 4y = 7
5x + 10y = 15
If you were going to solve the system above, what
would be the best first step according to the
strategy you just learned?
Solve for x in the first equation.
Solve for y in the first equation.
Solve for x in the second equation.
Solve for y in the second equation.
explain your reasoning .
Answer:
The answer is C
and the second answer is
Solving for x in the second equation produces a coefficient of 1 or –1. This choice avoids fractions. Each term in the second equation can be divided by 5. That makes x easy to isolate.

The value of a computer decreases with its age, until it is worth nothing. A computer that was purchased new (age 0 years) for
$2200 is worth $1540 after 6 years.
The linear function V(x) that expresses the value of the computer as a function of the age (x) in years is V(x)= type your answer_
The value of the computer after 8 years is $ type your answer...
After type your answer.
years the computer will be worth nothing.
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$

HELP ME PLEASEE THIS IS FOR MY GRADEE! ILL MARK BRAINLEST
where do the numbers go and explain how you decided where to place the numbers
Answer:
Between 0 and 1 goes 1/4 then after that is 5/8 then between the 1 and the 2 put 1 and 3/8/
Step-by-step explanation:
The reason for this is simply smallest to biggest. Which is bigger 1/4 or 5/8? Well if you want you can put it into a decimal: 1/4 = 0.25 and 5/8 equals 0.625. So 0.25 is closer to 1 and then 5/8 is the next closest to 1 but it is closer to 2. And lastly 1 and 3/8 is more then 0 and it's more then 1 so it goes in between 1 and 2 This is how it goes: 0 1/4 5/8 1 1 and 3/8 2
