Answer:
See image below:)
Step-by-step explanation:
Explanation:
x + 3y = 2
<u>Converting it to slope intercept form</u>:
y = mx + b [where m is slope, b is y-intercept]
<u>Make y the subject</u>:
<u>which reveals slope</u>:
Answer:
Option D In step 4 Keith should have subtracted 5 from each side
Step-by-step explanation:
step 1
we have
f(x)=7x+5 -----> given
step 1 is correct
step 2
Change f(x) to y
y=7x+5
so
step 2 is correct
step 3
Exchange x for y and y for x
x=7y+5
so
step 3 is correct
step 4
Subtract 5 each side
x-5=7y+5-5
x-5=7y
<u><em>step 4 is not correct</em></u>
step 5
Divide by 7 each side
(x-5)/7=y
step 6
Change y to g(x)
(x-5)/7=g(x)
step 7
switch sides of the equation
g(x)=(x-5)/7
therefore
In step 4 Keith should have subtracted 5 from each side
14. The answer is A; 8 is the opposite reciprocal of -1/8, which is what you need for perpendicular slope.
15. The answer is C; you can guess and check by plugging points into the equation.
By choosing n = 2 you were able to show that they were the "equal to" part of the inequality.
2! = 1
× 2 = 2
Try using n = 3
