Answer:
Step-by-step explanation:
1) Solve for 2x - y = 9
A. Solve for y.
2x - y = 9
B. Subtract 2x from both sides.
-y = 9 - 2x
C. Multiply both sides by -1.
y = -9 + 2x
D. Regroup terms.
y = 2x - 9
2) Substitute y = 2x- 9 into 4x² + 3y² - 2x + y = 16
A. Start with the original equation.
4x² + 3y² - 2x + y = 16
B. Let y = 2x - 9.
4x² + 3(2x - 9)² - 2x + 2x - 9 = 16
C. Simplify.
16x² - 108x + 234 = 16
3) Solve for x in 16x² - 108x + 234 = 16
A. Solve for x.
16x² - 108x + 234 -= 16
B. Move all terms to one side.
16x² - 108x + 234 - 16 = 0
C. Simplify 16x² - 108x + 234 - 16 to 16 x² - 108x + 218
16 x² - 108x + 218 = 0
D. Use the Quadratic Formula.
,
E. Simplify solutions.
4) Substitute into y = 2x - 9.
1) Start with the original equation.
y = 2x - 9
2) Let x =
3) Simplify
Answer:
they all have the same lengths , angles, size, shape.
Step-by-step explanation:Hopefully this helped, u dont need zoom-just HMU and I will help u
<em>-Have a great day! :)</em>
I am assuming that you will need to do Pythagorus Theorem to find the 3rd side length. If thats the case then you will need to do the following formula : a^2 + b^2 = <span>√(c)
So 15^2 + 30^2 = </span>√(c)
= 33.5 inches
The third angle would be 115 because 180 - 45 - 20 = 115
I hope this helped.
