y=4x+2. eq1
y=5x. eq2
4x=2-y
x=(2-y) /4
substitute in equation 2
y=5(2-y) /2
y=(10-5y)/2
4y=10-5y
9y=10
y=10/9
substitute in equation 2 or 1
substituting in equation 2
10/9=5x
x=10/45
x=10/45 y=10/9
you can verify it also.

The mean, because data distribution is skewed to the right. You answer is correct
Answer:
For this system of equations there is infinitely many solutions.
Step-by-step explanation:
Given the equations: -4x + 4y = 32 and 3x + 24 = 3y, we need to first get them both in standard form (Ax + By = C) in order to complete the method of elimination to solve. The first equatoin is already in standard form, however, in order to convert the second equation, we will need to use inverse operations to move the '3x' to the other side of the equation by subtraction of this term from both sides: 3x - 3x + 24 = 3y - 3x or 24 = -3x + 3y. Rearranging the equation gives us: -3x + 3y = 24. In order to use elimination to solve, we must first multiply the first equation be a factor of 3 and the second equation by a factor of -4 in order to have opposite coefficients:
3[ -4x + 4y = 32] = -12x + 12y = 96
-4{-3x + 3y = 24] = 12x - 12y = -96
You can see that if we add these too equations together, we get 0 = 0, which indicates that they are both the same line, making our answer infinitely many solutions.
To work out the surface area of a triangular prism:
Base: l x w
= 4 x 7
= 28 feet
Top: l x w
= 5 x 7
= 35 feet
Two sides: 1/2 x b x h
= 1/2 x 4 x 3
= 6 + 6 (for the other side)
= 12 feet
Left side: l x w
= 3 x 7
= 21
Add all of them up:
= 28 + 35 + 12 + 21
= 96 square feet
Answer:
Team tackle scored 9 points.
Team Sack scored 6 points.
Step-by-step explanation:
9+6=15 and 9 is three more than 6.
