Answer:
25%
Step-by-step explanation:
4 days of 16 days is 25% or 1/4
Hope this helps! ;-)
Answer:
x=-5, y=-11
Step-by-step explanation:
When approaching systems of equations, you must either solve via subsitution or through manipulation to get one term aglebraically; either way, you want to solve for one variable at a time. So, we have
Multiply line A by (3) and then add it on to Line B. From there break it down and sub in what you get for y into either equation.
Answer:
J
Step-by-step explanation:
h = 1.32t + 1.56
Replace t with 4 (days):
h = 1.32(4) + 1.56
Multiply:
h=5.28 + 1.56
Add:
h=6.84
The correct choice is J

When you're graphing a line in slope-intercept form (y = mx + b), your first step is to look at b, which is your y-intercept. The y-intercept is where your line touches the y-axis.
Slope-intercept form is y = mx + b, but for y = -5x doesn't have a b, so you have to add one. You can do this by adding + 0 to the end, since it won't change your equation.
y = -5x + 0
b = y-intercept = 0
m = slope = -5
So, your line will start at 0 on the y-intercept, which will be at the origin point (0,0).
Your slope is -5, or , so you'll go down 5 and then to the right 1.
A few points on your line should be (0,0), (1,-5), and (-1,5).
