Answer
Step-by-step explanation:
The answer would be y=-x-3. 3x+3y=-9 is in standard form and you want it to be in y=mx=b form (slope-int) so subtract 3x by both sides. Now, you have 3y=-3x-9. Divide 3 to both sides, now you will get y=-x-3.

Answer:
[tex]\boxed {x = -2}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]-5x - 4 = 3x + 12[/tex]
-Take [tex]3x[/tex] and subtract it from [tex]-5x[/tex]:
[tex]-5x - 4 - 3x = 3x - 3x + 12[/tex]
[tex]-8x - 4 = 12[/tex]
-Add [tex]4[/tex] to both sides:
[tex]-8x - 4 + 4 = 12 + 4[/tex]
[tex]-8x = 16[/tex]
-Divide both sides by [tex]-8[/tex]:
[tex]\frac{-8x}{-8} = \frac{16}{-8}[/tex]
[tex]\boxed {x = -2}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]-2[/tex].
Suppose the average yearly salary of an individual whose final degree is a master's is $ 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 $ thousand. Find the average yearly salary of an individual with each of these final degrees. The average yearly salary for an individual whose final degree is a bachelor's is $ nothing thousand and the average yearly salary for an individual whose final degree is a master's is $ nothing thousand.
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

Option A= 36 + 27 pi is the correct answer
Area of square= 6*6 = 36
Area of the remaining circle = 3/4*pi*r^2
= 3/4*pi*6^2= 27*pi
Thus, total area = area of square+ area of circle
36 + 27pi
The first golfer had a score of +6 and the second golfer had a score of -3. How many more shots did the first golfer take. 1.The first golfer had a score of +6 and the second golfer had a score of -3. How many more shots did the first golfer take. 1.
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.
Answer:
9

if the radius of Circle A is 2 inches the radius of circle B is 3 1/4 inches and the radius of circle C is 1 inch what is the perimeter of ABC
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)
P= 2( 6 1/4)
P = 12 1/2

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?
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
5. Eighteen more than four times a number is 114. Write and solve the equation.
a. 18+ 4x = 114; x = 24
b. 18 - 4x = 114; x = -24
c. 18x + 4 = 114; x = 93
d. 18x - 4= 114; x = 6.5
Answer:
A.
Step-by-step explanation:
18 more than meaning addition
Four times a number meaning multiplying a number we don't know yet
Is 114, or equals 114.
Equation: 18 + 4x = 114; x = 24
18 + 4(24) = 114
18 + 96 = 114
How do i graph -7x-2y=-21???
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.)
