Answer:
Slope (m)= 0
Step-by-step explanation:
There is no slope due to a vertical line
x= 7
How do you graph the equation f(x)=10x+40??
1 answer:
Ok so linear equations come in the form
y = mx + b
B is the y-intercept. In this equation the y intercept is 40. A y- intercept is where the graph crosses the y axis so at the point (0,40) the graph crosses the y axis.
M is the slope which is rise over run so if the slope was 10 (which it is) 10 is equivalent to 10/1 so you move up 10 units for every 1 unit you move across.
So to graph this equation, you would draw your first point at (0,40). For your next point, you would move right one unit, and up 10 units. Draw a point there which would be (1, 50). Hopefully you understand. For going left from the y intercept point, you would move left 1 and down 10.
Actual graph above.

Answer:
Surface area of larger solid is = 25 square feet.
Step-by-step explanation:
Given that,
Volume of smaller solid = 8 cubic feet
Volume of larger solid = 125 cubic feet
We know that,
Volume is the function of cube of dimensions.
and area is the function of square of dimensions.
So,
8 = 2³
125 = 5³
Ratio of sides = 2 : 5
Ratio of surface area = 4:x (let surface area of larger solid x)
So,
x = 25 sq ft
surface area of the larger solid = 25 sq ft
That's the final answer.
