5x+ 10= -4x -17
⇒ 5x+ 4x= -17 -10
⇒ 9x= -27
⇒ x= -27/9
⇒ x= -3

Final answer: x=-3~

Can someone explain this I dont understand it

Y = mx + b

m is your slope AKA rate of change
b is the y intercept.

from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)

slope is rate of change. to figure this out remember slope = rise over run:

slope = \frac{rise}{run}

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1

Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2

Now plug these numbers into the rise over run formula:

slope \: = \frac{1}{2}

Now we have everything we need to put into our formula for a line:

y = mx + b
y = \frac{1}{2} x + 18

For number 16 you should get:

y = \frac{1}{5} x + 3

after you do the same steps again yourself

2x+5=3(x+5)-x
WARRIOR [948]

Answer:

There are no solutions

Step-by-step explanation:

Simplify both sides of the equation.

2x+5=3(x+5)-x\\2x+5=(3)(x)+(3)(5)+-x\\Distribute\\2x+5=3x+15+-x\\2x+5=(3x+-x)+(15)\\CLT\\2x+5=2x+152x+5=2x+15\\

Subtract 2x from both sides

2x+5-2x=2x+15-2x\\5=15

Subtract 5

5-5=15-5\\0=10
