Answer:
y = -7
Step-by-step explanation:
Put x = 2 in any one of the equation
5x +2y = -4
5*2 + 2y = -4
10 +2y = -4
2y = -4 -10
2y = -14
y = -14/2
y = -7
Answer:
x ≈ 11.7
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = 
= 
( multiply both sides by 13 )
13 × cos26° = x , then
x ≈ 11.7 ( to the nearest tenth )
Answer: -5 x -5
The exponent two means the other number multiplied 2 times, so the equation is -5 x -5. The answer to the equation is -25.
