One thing that is beneficial about using estimation is that if your answer is wrong, estimating the 2 numbers would give you a reason to know that this answer you found is nowhere close to your estimated answer. Then you are able to change your answer and the reason you did that was that because of estimating.

sergij07 [2.7K]

Answer:

m = -10

Step-by-step explanation:

0.61m - 1.51m = 9

-0.90m = 9

mutiply both sides by -1.111111111111, twelve 1's after the decimal point

also to find what number u need to multiply to make -0.9m to m, divide 0.9 by 1 and that equals 1.111111111111 so yea a lot of ones haha

A line passes through (5,-2) with a slope of 1/4. Write the equation in slope-intercept<br> form.

trapecia [35]

Answer: y = $\frac{1}{4}$ x - 3 $\frac{1}{4}$

Step-by-step explanation:

Slope-intercept form is in the form of y=<em>m</em>x + <em>b</em> where m is the slope and b is the y-intercept.

We are given the slope, so we will plug this in.

y = <em>m</em>x + <em>b</em>

y = ( $\frac{1}{4}$ )x + <em>b</em>

<em />

Now, we will solve for the y-intercept by plugging in the point they give us.

y = ( $\frac{1}{4}$ )x + <em>b</em>

(-2) = ( $\frac{1}{4}$ )(5) + <em>b</em>

-2 = 1.25 + <em>b</em>

-3 $\frac{1}{4}$ = <em>b</em>

<em />

Lastly, we will plug this variable into the equation we wrote above for our final answer.

y = $\frac{1}{4}$ x - 3 $\frac{1}{4}$

R 2x-6+3=6x-5 please help

frozen [14]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$2x - 6 + 3 = 6x - 5$

$2x - 3 = 6x - 5$

$6x - 5 = 2x - 3$

Add sides 5

$6x - 5 + 5 = 2x - 3 + 5$

$6x = 2x + 2$

Subtract sides 2x

$- 2x + 6x = - 2x + 2x + 2$

$4x = 2$

Divide sides by 4

$\frac{4x}{4} = \frac{2}{4} \\$

$x = \frac{1}{2} \\$

_________________________________

CHECK :

$2( \frac{1}{2} ) - 3 = 6( \frac{1}{2} ) - 5 \\$

$1 - 3 = 3 - 5$

$- 2 = - 2$

Thus the solution is correct....
