Answer:
-7 and 21
Step-by-step explanation:
y-2y=7 (sub x=7 to the equation)
-y=7
y=-7 (not sure of its correct)
if y=-7,
x-2(-7)=7 (sub y=-7 into equation)
x-14=7
X=7+14
X=21
Answer:
c² = 34
Explanation:
Pythagorean Theorem: a² + b² = c²
- Insert 3 and 5 into the equation
3² + 5² = c²
3² = 9
5² = 25
9 + 25 = 34
34 = c²

Answer: Y= 67
Step-by-step explanation:
The equation says;
Y= 15x + 7

We have Y= 15(4)+7 by substituting the value of x for the equation. So, we have
Y=60+7
Y= 67
