Answer:
Pic 1: y=(-3/5)x+4
Pic 2: y=(1/4)x-4
Step-by-step explanation:
Answer:
5 4/9
Step-by-step explanation:
9 * 5 = 45
49 - 45 = 4
Inequality 1: y ≤ 5x + 1
Inequality 2: y > x - 2
#1. The slope is 5, the y-intercept is 1, the shaded area is below the line and the line is solid, which means that y is less than or equal to the equation. (you add the "equal to" because the line is a solid line)
#2. The slope is 1, the y-intercept is -2, the shaded area is above the line and the line is dotted, which means that y is greater than the equation
1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
Answer:
Step-by-step explanation:
Volume of a cone=1540
, Radius=7cm.
The height of a cone=h
When we need to find the height of a cone, we can use the formula of the volume of a cone, which is 
to find the height of a cone.
Put the pi value=22/7 and the value of radius which is 7 cm into the formula.
Move 
to another side. 1540 divided by to calculate what is the value of h, h is the height of a cone. Like this.
Rearrange the h.
