Let p represent her present test point total, and t represent the necessary average on the next two tests.
.. p +2t ≥ 450 . . . . she wants an A grade after the next two tests
.. t ≥ (450 -p)/2 . . . her required average on the next two tests
Answer:
y = 2x - 6
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The y-intercept is already given and is -6.
By c intercept, I am assuming you meant x-intercept. With an x-intercept of 3, the point is (3,0). With a y-intercept of -6, the point is (0,-6).
Use the two points to find the slope using the following equation.

Plug the points into their respective positions and solve.

The slope is 2.
Your equation is y = 2x - 6.
5.6 gallons of paint are needed to cover 1,960 square feet.
two gallons are needed for 700, so divide 700 by 2 to get square feet per gallon.
then divide 1,960 by 350 to get the gallons of paint needed
5.6 gallons
Hope this helps!
