Answer:
The y-intercept is at (0,8), so you can graph that point. Then the slope is -3/5. So the change in y coordinate divide the change in x coordinate is always -3/5. Thus 8-y/0-x=-3/5. You can choose any value for y and x as long as 8-y=-3. And 0-x=5. The point on the graph will just be (x,y) for the values you find.
Answer:
D) triangle
Step-by-step explanation:
The attached image may be helpful to visualizing what the cross section looks like. It is a triangle.
Answer:
x = - 5
Step-by-step explanation:
Using the rule of exponents
•
⇔ 
Given
= 32
= 32
= 
Since the bases are equal, both 5, equate the exponents
Hence x = - 5
Answer:
9.784
Step-by-step explanation:
remember this formula for right triangles (a^2+b^2=c^2)
so 7.4^2+6.4^2=c^2
54.76+40.96=c^2
95.72=c^2
this is where we do this

square root of 95.72 is around 9.784
