Can someone please tell me what the equation of the line is in standard form by using the graph? I need to sleep and this is due tomorrow. Whoever answers, I’ll mark you as brainliest!!

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.)

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

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

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

Simplify...

-3x=9

Divide by -3 to get

x= 9/-3

x= -3

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:  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

Answer: 15/17

Step-by-step explanation: I took the K12 Math test!

Based on the trigonometric calculations, the value of cosC is equal to: C. 15/17.

In Mathematics, there are six (6) types of trigonometry graph that are used to graphically represent a trigonometric function and these include:

Based on the right-angled triangle attached, we can deduce the following parameters:

Opposite side (BA) = 8 units.

Adjacent side (BC) = 15 units.

Hypotenuse (AC) = 17 units.

In trigonometry, cosine (cos) is given by this mathematical expression:

cosC = BC/AC

cosC = 15/17.
