First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.

What is -2(5+6m) + 16 = -90 ?<br> Can you please show with detail

GarryVolchara [31]

Answer:

m = 8

Step-by-step explanation:

-2(5 + 6m) + 16 = -90

Start by distributing -2 inside the parentheses. This means you will multiply everything inside the parentheses (5 + 6m) by -2.

-10 - 12m + 16 = -90

Simplify the left side of the equation by combining like terms.

6 - 12m = -90

Subtract 6 from both sides of the equation to isolate the term containing the variable m and to move all other terms to the other side (right) of the equation.

-12m = -96

Divide both sides of the equation by -12 to isolate and solve for m.

m = 8

(5,12) with a slope m=10 the equation of the line is

motikmotik

Answer:

y= 10x-38

Step-by-step explanation:

Equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.

Given that m=10,

y= 10x +c

Now substitute the coordinates into the equation.

When y=12, x=5,

12= 10(5) +c

12= 50 +c

c= 12 -50

c= -38

Thus the equation of the line is y= 10x -38
