Answer: She mixed up the slope and y-intercept when she wrote the equation in step 3.
Step-by- explanation:
Hope this helps :)
Answer:
n = 5.4
Step-by-step explanation:
Equation: 4n = 21.6
To solve this equation for n, divide both sides by 4 to get n by itself.
<u />
<u>Step 1: Divide both sides by 4</u>
4 * n / 4 = 21.6 / 4
n = 5.4
Answer: n = 5.4
Answer:
f(-1) = 0 and f(4) = 0
Step-by-step explanation:
look at graph to see what point(s) is/are intersecting the y-axis, then use the y-value of the ordered pair
3 = 379.25
4 = 1587.50
5 = 198.88
6 = 1217.50
7 = 1788.20
8 = 1408
9 = 205
10 = 1516
11 = 2034
12 = 880
13 = 1994.57
14 = 1157.77
15 = 38812.50
remember to round the numbers, and also write random numbers everywhere so it looks like you did it.
Answer:
No solution
Step-by-step explanation:
-3x + 3y = 4
-x + y = 3
<u>Solve the equation for x:</u>
<u>Move the variable to the right side and change its sign</u>
-x + y = 3
-x = 3 - y
<u>Change the signs on both sides of the equation</u>
-x = 3 - y
x = -3 + y
<u>Substitute the given value of x into the equation -3x + 3y = 4</u>
-3x + 3y = 4
x = -3 + y
-3(-3+y)+3y=4
<u>Solve the equation for y</u>
-3(-3+y)+3y=4
y = 0
There is no solution for y.
And since there's no solution for y, the system has no solution.
