Answer:
1 no
2 I don't know
3 no
4 yes
5 2.5 is the slope
6 -0.5
7 no slope
Step-by-step explanation:
1 no because the y overlaps
2 not sure
3 it over laps
4 it never overlaps
5 y=2.5x-3
6 y=-0.5x+1
7 no slope it's just x=-2
for the 5-7 you can type that into demos and get more info
y=mx+b
m is the slope and b is y intercept
Answer:
(-2, -4)
Step-by-step explanation:
You can complete the square of the equation to get
y+(4/2)^2 = x^2+4x+(4/2)^2
y+4 = x^2 + 4x + 4
y+4 = (x+2)^2
y = (x+2)^2 - 4
This gives the form y = a(x-h)^2 + k where (h, k) is the vertex of the equation. You can also arrive at the same conclusion by making some observations of the equation. (x+2)^2 minimum value is going to be 0 since and negative values resulting from x+2 is going to become positive because of the square. So the minimum value is when x+2 is 0 or when x is equal to -2 and when it's at that minimum value of 0 it's going to have 4 subtracted from it which gives the vertex of (-2, -4)
Answer:
2 * 0.75 + 0.50 + 4 * 1.25
$7.00
Step-by-step explanation:
Expression
2 * 0.75 + 0.50 + 4 * 1.25
Evaluate
1.50 + 0.50 + 5.00
$7.00
The distance from the park to the grocery store is 0.9 mile.
Ezra runs 8 tenths of that distance and walks the rest of the way. The distance
ezra runs can be solve by multiplying 8/10 to the total distance.
X = 0.9(8/10)=0.72 mile
No because it would be 7/6 which is not proportional.
