3x+y=15
First convert the equation into slope intercept form. y=mx+b
Where m is the slope and b is the y-intercept.

3x+y=15
Subtract 3x from both sides
y=-3x+15
Here slope, m=-3

Answer: Slope is -3.  Option C is correct

Slope intercept form is y = mx + b

so you must isolate the y first by moving the x (and anything attached to it) to the other side

3x (-3x) + y = (-3x) + 15

y = -3x + 15

The slope is m, which is next to x

-3x is what you are looking at

-3 is your slope

C. is your answer

hope this helps

leva [86]

Answer:

SUE: (18-x)-5

TONY: (18+x) / \frac{1}{2}

Sue has 18 sweets

Tony also has 18 sweets

Sue gives x sweets to Tony

Sue then eats 5 of her sweets

Tony then eats half of his sweets

(18-x)-5=(18+x)/ 1/2

x= -7.6

PLSSSSSSSSSS URGENT I NEED HELP!!!
Novosadov [1.4K]

Answer:

The values of a and b are:

  • a = 2
  • b = 2

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = ax+b

where

  • a is the slope
  • b is the y-intercept

From the diagram of the line graph, we can fetch the two points

  • (0, 2)
  • (-1, 0)

Determining the slope between (0, 2) and (-1, 0)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:2\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)

a=\frac{0-2}{-1-0}

a=2

Thus, the value of a = 2

We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept b = 2

now substituting a = 2 and b = 2 in the slope-intercept form of the line equation

y = ax+b

y = 2x + 2         ∵ a = 2 , b = 2

Thus, the line of equation is:

y = 2x+2

now comparing with y = ax+b

Here:

a = 2

b = 2

Therefore, the values of a and b are:

  • a = 2
  • b = 2

7x - 12 - 3x = 2(2x + 5)<br><br> Solve for 15 Points
emmainna [20.7K]

Answer:

x = Ø

Step-by-step explanation:

7x - 12 - 3x = 2(2x + 5)

4x - 12 = 4x + 10

4x = 4x + 22

0x = 22

x = Ø

Hope this helps dude

.8787... as a fraction
LuckyWell [14K]

Step-by-step explanation:

Write 0.8787 as

0.8787/1

Multiply both numerator and denominator by 10 for every number after the decimal point

0.8787 × 10000

1 × 10000

=

8787/10000

Reducing the fraction gives

8787/10000
