How do i graph -7x-2y=-21???
Answers
Answer:
-7/2 is the slope. -10.5 is your starting point on the y-axis. You go from -10.5, up 7 and over to the left 2 times because it's negative.
Step-by-step explanation:
-7x-2y=-21
-2y=7x-21
y=-7/2x-21/2
y=-7/2x-10.5
Hope this helps!
You might want to simplify the equation first. Basically, we'll use y = ax+b instead.
[tex]-7x-2y=-21\\-2y=-21+7x\\y=\frac{-21}{-2}+\frac{7x}{-2} \\y=\frac{21}{2}-\frac{7x}{2}\\y=\frac{21-7x}{2}[/tex]
Should have been like this then you are able to graph.
To graph, you need to find the x-intercept and y-intercept.
(1) Find x-intercept, substitute y = 0
[tex]0=\frac{21-7x}{2} \\0=21-7x\\7x=21\\x=3[/tex]
Thus, the graph has a x-intercept at (3,0). For those who are wondering where does the fractional 2 go, just multiply the whole equation by 2 to get rid of the fraction.
(2) Find y-intercept, substitute x = 0
[tex]y=\frac{21-7x}{2}\\ y=\frac{21-0}{2}\\ y=\frac{21}{2} \\[/tex]
Also 21/2 = 10.5, Thus the graph passes y-axis at (0, 10.5)
Now plot the graph, make a line from x-intercept and y-intercept and you should get like this (Picture below.)

Complete question :
Suppose the average yearly salary of an individual whose final degree is a master's is $55 thousand less than twice that of an individual whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn ?$116 thousand. Find the average yearly salary of an individual with each of these final degrees.
Answer:
Average salary of a bachelor's degree holder = $57,000
Average salary of a master's degree holder = $59,000
Step-by-step explanation:
Let:
Average salary of a bachelor's degree = b
Salary of a master's holder = 2b - 55000
Combined salary of both degrees :
b + (2b - 55000) = 116000
b + 2b - 55000 = 116000
3b = 116000 + 55000
3b = 171000
Divide both sides by 3
3b/3 = 171000/3
b = 57000
Hence,
Average salary of a bachelor's degree holder = $57,000
Average salary of a master's degree holder = 2(57000) - 55000 = 59,000

Answers
Answer:
9 more shots
Step-by-step explanation:
If the first golfer had a score of +6 and the second golfer had a score of -3, in order to know how many more shots the first golfer take, we will take the difference between both goals as shown;
= 6-(-3)
= 6+3
= 9
Hence the first golfer took 9 more shots than the second.

Jennifer invites her friends over for a party. Her mother buys a value pack of party favors. She removes 2 damaged pieces from the entire lot and divides the rest equally in 10 goody bags. If each bag contains 7 party favors, how many party favors were there initially?
Answers
Answer:
72
Step-by-step explanation:
Call the amount she started with, x
she removes 2
x - 2
then she divides it by 10
(x - 2)/10
each bag contains 7 pieces
(x - 2)/10 = 7
so now solve using inverse operations
(x - 2)/10 = 7
*10 *10
x - 2 = 70
+2 +2
x = 72

Answers
Answer: The perimeter of triangle ABC is 12 1/2 inches.
Step-by-step explanation: Each radius given is used twice in the diagram to connect to the radii of the adjacent circles to form the sides of the triangle.
So the perimeter of the triangle is found by adding twice the length of each radius.
P= 2( 2 + 3 1/4 + 1)
