It is the line in the top right corner. I figured this out using a graphing calculator and also because it would be a solid line because it's greater than or equal to.
Answer: about 78 mL
Step-by-step explanation:
When you see the liquid in a curved shape, you want to look at the very bottom of the curve. The bottom shows that our answer will be in the 70 mL, but close to 80. If you look at the lines in between, we can see that there are 5 lines, meaning each line represents 2 mL. Now, we count up and reach 78 mL.
Answer:
x=4, y=-4/3. (4, -4/3).
Step-by-step explanation:
8x+9y=20
x=-3y
---------------
8(-3y)+9y=20
-24y+9y=20
-15y=20
y=20/-15
simplify
y=-4/3
x=-3(-4/3)=12/3=4
(-1,1) is a solution to y=3x+4 but is not a solution to 4y-3x=-7
4y-3x=-7
Plug in the points
4(1)-(3(-1)) =-7
4+3 does not equal -7
