Answer:
21=3/7
Step-by-step explanation:
if you divide 21 by 7, you get 3. if you multiply 7x3 or 3x7, you get 21
Answer:
First and Second option
Step-by-step explanation:
The prediction is reasonable
No data is given in the scatterplot for a height of 80 inches, but a shoe size can still be predicted
Are the correct answers
M= 6- -9 / 2- -1 = 6+9 / 2+1 = 15/3 = 5
y-6=5(x-2)
y-6=5x-10
y=5x-4
-9=5(-1)-4
-9=-5-4
-9=-9
6=5(2) -4
6=10-4
6=6
Step 1: find the slope using the formula m=y2-y1/x2-x1
Step 2: plug the slope and one point into the point-slope formula and solve to find the equation of the line in y=mx +b form.
Step 3: test both points to see if the equation works.
Factor out it by 2.
2(b² - 13b + 40) = 0
b<span>²</span> - 13b + 40 =0
This equation can be solved using the quadratic formula. If you know what a quadratic formula is, then you can get the two values for b. For instance,
(b - 8)(b - 5) = 0
Separate the two "roots", you will get:
b - 8 = 0
b = 8
and
b - 5 = 0
b = 5
Therefore the two values of b are 8 and 5.
