Answer:
the answer is D
Step-by-step explanation:
12 times 5 equals 60 1 times 15 eqauls 15 60+15=75
it's an equation so we got
For each t-shirt sold, which I'll call <em>t</em>, 8th grade makes $15.
For each hat sold, which I'll call <em>h,</em> 8th grades makes $5.
They want to raise $900
A: The equation to represent this situation is 15t+5h=900 because if 8th grade adds up all the profits from both hats and t-shirts, the goal is to make $900, so the total profit from shirts and hats should equal 900 dollars.
B: I'm just going to choose random numbers. Let's say nobody wanted to buy a hat from the 8th graders (h=0). You'd end up with
15t+5(0)=900
15t=900
t=60 - If they sold 0 hats they would have sold 60 shirts to raise $900
Now let's say it was the other way around - nobody wanted to buy t-shirts
15(0)=5h=900
5h=900
h=180 - If they sold 0 t-shirts they'd have to sell 180 hats to raise $900
Finally let's say they sold 30 t-shirts
15(30)+5h=900
450+5h=900
5h=450
h=90 - They'd have to sell 30 t-shirts and 90 hats to raise $900
Answer:
A
Step-by-step explanation:
Take any two points on the line
(-4,0) and (0,-1) find the slope
slope= y2-y1/x2-x1

y-y1 = m(x-x1)
![y-0=\frac{-1}{4}[x-(-4)]\\\\y=\frac{-1}{4}(x+4)\\\\y=\frac{-1}{4}*x+4*\frac{-1}{4}\\\\y=\frac{-1}{4}x-1](https://tex.z-dn.net/?f=y-0%3D%5Cfrac%7B-1%7D%7B4%7D%5Bx-%28-4%29%5D%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B4%7D%28x%2B4%29%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B4%7D%2Ax%2B4%2A%5Cfrac%7B-1%7D%7B4%7D%5C%5C%5C%5Cy%3D%5Cfrac%7B-1%7D%7B4%7Dx-1)
