Let:
T = Total money they have
Dc = Dog collar
x = Number of bags of food
Let's solve the inequality:
This means that they can buy 12 bags of food at most.
Since they plan to buy 2 bags of food:
This means they can do it and have $ 11.5 to spare
Answer: B
Step-by-step explanation:
The slope-intercept is usually written as y = mx + b form, where m is the slope, and b is the y-intercept. The y-intercept is the y value when x is equal to 0.
We can first eliminate C, because the y-intercept of the graph is 1.
To solve for slope, which is the m, choose two points, (-1, 5) and (1, -3).
Slope = (y2 - y1) / (x2 - x1)
= (-3 - 5) / (1 - (-1))
= (-3 - 5) / (1 + 1)
= -8/2
= -4
Plug in the slope and y-intercept, we get y = -4x + 1
Hi there!
Use slope formula to solve for the slope of the line:
Plug in points into the equation. We can use the points (0, -10) and (25, -5):
Step-by-step explanation:
g(x)= -16x² + 72x + 80
Plug 2 in to check if it's correct.
g(2)= -16(2)² + 72(2) + 80
-16(4)+128+80
-72+128+80
= 136
