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.)

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

Ingredient 8 servings
Dried split peas: 2 and 1/4 c.
Water: 2 qt
Chopped onion: 3/4 c.
Chopped celery: 1 c.
Ham shank: 2 lb.
The basic recipe for split pea soup serves 8 people. Find the amount of each ingredient needed to serve 32 people.
Answer:
Dried split peas: 9 cups
Water: 8 quarts
Chopped onion: 3 cups
Chopped celery: 4 cups
Ham shank: 8 pounds
Step-by-step explanation:
Since the basic recipe serves 8 people and you need to serve 32 people, you just multiply each ingredient by 4. (32÷8=4)
Dried split peas: 2 1/4 c. x 4 = 9 cups
Water: 2 qt x 4 = 8 quarts
Chopped onion: 3/4 c. x 4 = 3 cups
Chopped celery: 1 c. x 4 = 4 cups
Ham shank: 2 lb. x 4 = 8 pounds

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

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
