Answer: (4,2). Explanation: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable. The Elimination Method
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
variable equation. It is relatively difficult to determine the values of x and y without manipulating the equations. If one adds the two equations together, the x s cancel out; the x is eliminated from the problem. Hence it is called the "elimination method”.
The correct questions says 5% each year for Company 2.
The amount invested in companies A and B are; $10,000 and $2000 respectively.
<h3>Percentages on Investment</h3>
Let the amount in Company 1 be; x
Let the amount in Company 2 be; y
Hence, we have the equation;
Additionally, 6% is earned on company 1 and 50% on company 2.
Therefore, we have;
by solving the equation simultaneously;

Answer:
C. C only
Step-by-step explanation:
Well to determine if the given graphs are functions we need to do the vertical line test to all the graphs,
A. This fails the vertical line test because the vertical line could pass through 2 points on the lines.
B. this also fails because a vertical line could pass through 2 points.
C. This passes because the vertical line doesn’t touch 2 points.
The sum of all five angles is 540 degrees.
A) 4*congruent angles + 5th angle = 540
B) (5th angle) -30 = 2*cong angle
A) 5th angle = 540 -4*cong angle
B) 5th angle = 2*(cong angle) -30
Multiplying B) by -1
B) -5th angle = -2*(cong angle) +30 then adding to A)
A) 5th angle = 540 -4*cong angle
-2*(cong angle) +30 = 540 -4*cong angle
2*(cong angle) = 510
*****************************************
By trial and error I determined
each congruent angle = 95
5th angle = 160
