Solve the system of linear equations by elimination. Write your answer in the form (x,y)
-7x-8y=9
-4x+9y=-22
Answer:
Solution: (1,-2)
Step-by-step explanation:
System of Equations
Given the equations:
[tex]-7x-8y=9\qquad\qquad [1][/tex]
[tex]-4x+9y=-22\qquad\qquad [2][/tex]
We'll solve it by elimination. It means eliminating one of the variables by equating their coefficients. We select the variable y. To eliminate it, multiply the equation [1] by 9 and the equation[2] by 8:
-63x-72y=81
-32x+72y=-176
Adding up both equations:
-95x=-95
Solving:
x=-95/(-95)=1
x=1
Now to eliminate x and find y, multiply [1] by 4 and [2] by -7:
-28x-32y=36
28x-63y=154
Adding up both equations:
-95y=190
Solving:
y=190 / (-95) = -2
y=-2
Solution: (1,-2)

You find a pair of jeans on a clearance rack that originally cost $64. They were marked down 50%. The clearance price sign says an additional 50% off. Johnny says that you do not need to pay anything for the jeans. Do you agree? Why or Why not? Make sure that your answer is given with at least four sentences.
Answer and explanation:
Original cost of jeans =$64
Markdown by 50%= 0.50*64= $32
Additional discount by clearance sign 50% =0.50*32= $16
Therefore I disagree with Johnny. First the original price $64 was reduced by half of the price 50% of $64 =$32. Secondly the new price $32 is then also reduced by half of it 50% giving us $16. Therefore the discounts did not wipe off all the price as suggested by Johnny.

What are the definitions and properties of a parallelogram?A parallelogram is a rectangle with two pairs of parallel sides. The lengths of the opposite sides of the parallelogram are equal, and the angles of the opposite sides are the same. Also, the internal angles on the same side of the transversal are complementary. The sum of all internal angles is 360 degrees.
A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The lengths of the opposite or opposite sides of the parallelogram are equal, and the angles of the opposite sides of the parallelogram are equal.

-2k+13=-8k-35
What’s k
Answer:
k = -8
Step-by-step explanation:
-2k+13=-8k-35
Add 8k to each side
-2k+8k+13=-8k+8k-35
6k +13 = -35
Subtract 13 from each side
6k+13-13 = -35-13
6k = -48
Divide by 6
6k/6 = -48/6

The radius of the circle shown below is 3 inches.
What is the area of this circle, in square inches?
Answer:Multiply Pi (3.1416) with the square of the radius (r) 2. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Calculated out this gives an area of 28.2744 Square Inches.

help meeeeeee ASAP A triangle has side lengths of (r−10s) centimeters,(3r+2t) centimeters, and 2t−6s) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
−8s+4r−4t
−14st+6rt
4r+4t−16s
5rt−9rs−4st
The expression that represents the perimeter in centimetre of the triangle is 4r - 16s + 4t
Perimeter of a triangle
Perimeter of a triangle is the sum of the whole sides. The triangle has three sides. Therefore, the perimeter is the sum of the three sides.
The side length are as follows;
r - 10s3r + 2t2t - 6sTherefore,
perimeter = r - 10s + 3r + 2t + 2t - 6s
combine like terms
perimeter = r + 3r - 10s - 6s + 2t + 2t
perimeter = 4r - 16s + 4t

help I will crown brainliest!!!!
Answer:
Step-by-step explanation:
c. y = (x^2 + 3)(x + 4)
y = x^3 + 4x^2 + 3x + 12
d. y = (x^2 + x) / √x
y = (x^2 + x) / x^1/2
y = x^2/ x^1/2 + x / x^1/2
y = x^(2 - 1/2) + x(1 - 1/2)
y = x^3/2 + x^1/2
or x = √(x^3) + √x
e. y = 5 /x^2
y = 5x^(-2)
Need help finding the missing side of each triangle?
Answer:
x ≈ 11.6 m
Step-by-step explanation:
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² + 10.7² = 15.8²
x² + 114.49 = 249.64 ( subtract 114.49 from both sides )
x² = 135.15 ( take square root of both sides )
x = [tex]\sqrt{135.15}[/tex] ≈ 11.6 m ( to the nearest tenth )

The Answer is 1 over 7 times 7 times 7 times 7 times 7 times 7
Step-by-step explanation:
All you have to do is multiply the exponents.
[tex]7^{3*(-2)} =7^{-6}[/tex]
and the rule says :
[tex]x^{-a} = \frac{1}{x^{a} }[/tex]

1 over 7 times 7 times 7 times 7 times 7 times 7 is equivalent to (73)−2.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
Here we have,
(7^3)(−2)
=7^(-6)
=1/7^6
=1/7*7*7*7*7*7
Hence, 1 over 7 times 7 times 7 times 7 times 7 times 7 is equivalent to (73)−2.
