Answer:
Step-by-step explanation:
The slope formula is M=y2-y1
______
X2-X1
Ex. (-1,1) and (1,-2)
x1,y1 x2,y2
-2+1 -3
_____= ____
1+(+1) 2
Graph:
Any linear function can be quickly graphed using the form: y=mx+b
X: independent variable
y: dependent variable
M: slope
b: y-intercept
(When you don't have a denominator for M put a 1 Ex. 4--> 4/1)
Ex. y=-1/2x + 4
M= 1/2
B: 4
Rise/Run = -1/2 "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).
Answer:
12/5
Step-by-step explanation:
I did study island.
<span>If 43% of adults say cashews are their favorite kind of nut, then if you ask 12 adults the result should be: 12 adults x 43%= 5.16 adults.
If you round the result, you will get 5 of 12 adults saying that cashews are their favorite nut. Then the right option would be </span><span>(b) at least four</span>
Answer:
Step-by-step explanation:
The way in which terms are grouped in a sum is immaterial; the sum will be the same no matter where each added appears.
Answer: x = 8
<u>Step-by-step explanation:</u>
4x + 18 + 5x = 90
9x + 18 = 90 <em>Added like terms</em>
9x = 72 <em>Subtracted 18 from both sides</em>
x = 8 <em>Divided both sides by 9</em>
BONUS: The sum of these two angles is 90°, which means these angle are complementary.
