Answer:
-8/5
Step-by-step explanation:
The thing that makes lines different from other kinds of curves is their <em>constant rate of change</em>. We call this rate of change <em>slope</em>, and you usually see it represented with the letter <em>m</em>. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.
We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate <em>increases </em>by 5, while our y-coordinate <em>decreases </em>by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as
m = -8/5

Answer:
option C 2*x + 3*y = 7.20
4 *x + 2*y = 8.80
1.4
Step-by-step explanation:
PART A
Steve
2lbs of grapefruit
3lbs oranges for $7.20
kennedy
4lb grapefruit
2lb oranges for $8.80
price 1 pound grapefruit x
1 pound oranges y
Then for steve
2*x + 3*y = 7.20
for kennedy
4 *x + 2*y = 8.80
PART B
now we have to find y from above equations
2x + 3y = 7.20 multiply by 2 on both sides 4x + 6y = 14.4
4x + 2y = 8.80
next by substracting the above two equations we get
6y - 2y = 14.4 - 8.80
4y = 5.6
y = 1.4
Answer:
870
Step-by-step explanation:
the equation is S=30w+450
to find the answer just replace the w by 14
multiply 30 by 14 to get 420 and add 450 to it to get 870
Step 1. Collect like terms
(9y + 7y) + (11z - 4z)
Step 2. Simplify
16y + 7z
