Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y = -1/6x + 5

Step-by-step explanation:

Slope is -1/6 and y-intercept is 5

Answer:

y=[tex]\frac{-1}{6}[/tex]x+5

Step-by-step explanation:

y=mx+b

m= slope

b= y-intercept

-1/6 is the slope because it is the unknown variable

5 is the y-intercept  because it hits a perfect point on the y-axis

to find the slope i used rise/run the rise is -1 and the run is 6

the rise is negative because it is going to the left and essentially on a full graph that would be negative

hopefully this helps :) have a nice day !!

Answer:

37

Step-by-step explanation:

20 + 13 = 33

so 70 - 33 = 37 so the answer is 37

Answer+explanation

so subtract the diffference of 20 and 13 from 70

so first we find the difference and then subtract that from 70

use parenthases so

difference of 20 and 13 is equal to (20-13)

subtract that from 70

70-(20-13)

so you would do the pemdas and get 7 for the inside parethasees then do

70-7=63

Answers

Answer:

  D.  (43 +60) +40

Step-by-step explanation:

The purpose of changing the grouping in addition problems is to simplify the mental effort required as much as possible. This will generally mean grouping ...

"complementary" numbers, numbers with the same number of leading or trailing zeros, numbers with the same sign, and fractions with the same denominator.

Analysis

A. Numbers ending in 0 are already grouped; no change is needed.

B. Fractions with the same denominator are already grouped; no change is needed.

C. Numbers with the same (negative) sign are already grouped; no change is needed.

D. Numbers ending in zero could be grouped to make addition easier:

  43 +(60 +40) . . . . regrouping would be useful

We also note that in A and D, the sum of numbers ending in zero is 100, so these numbers are "complements" of each other. This is another reason for grouping them together.

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

answer:

y=1x-50

step-by-step explanation:

y=mx+b

m=slope

b=y-intercept

x=unknown variable

to find the slope i used rise/run

my rise was 3 and my run was also 3

3÷3=1

the slope is going to the right making it positive

the y-intercept is -50 because that is where the line hits the y-axis

good luck :) hopefully this helps

Evaluate the given expression when x = 3.

Enter the number only.

Answers

3^3 + 6*3+ 5
27 + 6*3 + 5
27+ 18 + 5
The answer is 50

Answer:

50

Step-by-step explanation:

If x=3 then x^3 would be 3 with the exponent of 3. It would look like 3x3x3=27

6x would be 6 times 3 which is 18.

Then you have just an extra 5.

Then add them all together. 27+18+5=50.

Therefore, your answer is 50.
