Answer:
x = 7
Step-by-step explanation:
Remember that the axis of symmetry (a vertical line that passes through the vertex) is exactly halfway between the two x-intercepts. Thus, the x-coordinate of the vertex is 7.
Answer:
3.5 Inches of snow left on Friday Night
Step-by-step explanation:
On Monday there was no snow
On Tuesday there was 3 inches
On Wednesday 3 - 0.5 inches= 2.5 inches of snow
On Thursday 2.5 + 2.5 inches= 5 inches
On Friday 5 - 1.5 inches=3.5 inches
Therefore the answer is that the was 3.5 inches of snow Friday night
Let's remember that 1 pound equals 0.0005 tons, so if we multiply 0.0005 x 20,000 the answer is 10, so 20,000 pounds equal 10 tons.
Y = mx + c
If y = 4, and x = 0, then:
4 = -1 (0) + c
c = 4
If c = 4:
y = -1 (2) + 4
y = -2 +4
y = 2
If you plug in the different values of x in each equation, the answer should be:
2,0,-2
(2, 6) because it is halfway between both endpoints
