Answer:
X=7
Step-by-step explanation:
8x-2y=48
8x-2(4)=48
8x-8=48
8(7)-8=48
56-8=48
Answer:
x = 10.9
Step-by-step explanation:
Since the triangle is right, use the tangent ratio to find the value of x
tan36° = 
= 
= 
Multiply both sides by 15
15 × tan36° = x
⇒ x = 10.9 ( to nearest tenth )

Answer: (5, -2, -3)
Answer:
y = 1/2 x²
Step-by-step explanation:
The coefficient of the first term in a quadratic, in our case here, x², will tell us how the graph stretches. This is akin to the slope within the linear graph. Similar to the slope, the smaller the coefficient value, or value of slope m, the shallower the angle.
When discussing quadratics, the larger the coefficient of our x² term, the steeper, and skinnier the graph. If we want to look for a graph that is wider than y = 2x², then we need to find a graph with a coefficient that is less than 2.
Our only option then is
y = 1/2 x²
