Answer:
(3, 0)
Step-by-step explanation:
The line through these points intersects the x-axis at x=3.
The x-intercept is (3, 0).
_____
The x-intercept can be computed from ...
x-intercept = x1 -y1(x2 -x1)/(y2 -y1)
= -3 -(-4)(6-(-3))/(2-(-4)) = -3 +4(9/6) = -3 +6
x-intercept = 3
__
Here, it is simple enough to plot the points and see where the line crosses the x-axis.
Answer: 0.194
Step-by-step explanation:
First step is to open the brackets.
7(19 - 9))/(4 * 5 * 18) = (133 - 63)/360
= 70 / 360
= 0.194
Answer:
G) y=3x+1
Step-by-step explanation:
1 would equal b = y-intercept
-3 is the slope = m
y-intercept form is y=mx+b
plug it in
y=-3x+1
Answer:
y=-3(x-1)^2+5
Step-by-step explanation:
The vertex form of a parabola is y=a(x-h)^2+k where (h,k) is the vertex.
We are given the vertex (h,k) is (1,5) so that makes the equation we have
y=a(x-1)^2+5.
We still need to find a.
We do have the point (0,2) on our parabola.
So replace (x,y) with (0,2) and solve for a.
2=a(0-1)^2+5
2=a(-1)^2+5
2=a(1)+5
2=a+5
-3=a
So the equation is
y=-3(x-1)^2+5
Answer:
6 buckets
Step-by-step explanation:
Look at the ratio:
1/3 cup kernels : 2 quarts popcorn
2/3 cup kernels : 4 quarts popcorn : 1 bucket . . . . multiply by 2
2 cups kernels : 3 buckets . . . . . . . . . . . . . . . . . . . . .multiply by 3
4 cups kernels : 6 buckets popcorn . . . . . . . . . . . . multiply by 2
