Simplify: 11y-110/50-5y

alexandr1967 [171]

<h2>Answer:</h2> $\frac{11y-110}{50-5y}=-\frac{11}{5}$

<h2>Explanations:</h2>

Given the following expression show below;

$\frac{11y-110}{50-5y}$

Factor out the GCF from both the numerator and denominator

$\frac{11(y-10)}{5(10-y)}$

This can also be expressed as;

$\begin{gathered} \frac{11(-10+y)}{5(10-y)} \\ \frac{-11(10-y)}{5(10-y)} \end{gathered}$

Cancel out the common expression

$\frac{-11\cancel{(10-y)}}{5\cancel{(10-y)}}=-\frac{11}{5}$

Hence the simplified form of the expression is -11/5

I need help with this homework question

If you divide 64/16, that equals 4, then you multiply 4*3 and your answer is 12. It looks something like this (for "showing your work" purposes);

64/16=4
4 x 3=12
answer=16 cups of sugar for 64 bags of tea

Which equation is a point slope form equation for line AB ?

kap26 [50]

Answer:

$y-5=\frac{3}{4}(x-6)$

Step-by-step explanation:

we know that

The equation of a line in point slope form is equal to

$y-y1=m(x-x1)$

step 1

Find the slope m

we have the points

A(-2,-1),B(6,5)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{5+1}{6+2}$

$m=\frac{6}{8}$

simplify

$m=\frac{3}{4}$

step 2

Find the equation of the line

we have

$(x1,y1)=(6,5)$

$m=\frac{3}{4}$

substitute

$y-y1=m(x-x1)$

$y-5=\frac{3}{4}(x-6)$

Write an equation of the line passing through the points (4,6) and (-2, - 18).

olga_2 [115]

Answer:

y = 4x – 10

Step-by-step explanation:

slope formula: $m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

point-slope formula: $y-y_{1}=m\left(x-x_{1}\right)$

Use slope formula and plug in your numbers: $m = \frac{-18-6}{-2-4 }$
Solve for slope $m = 4$
Use the point-slope formula to solve for the equation: $y-6=4\left(x-4\right)$
Solve and find equation: $y=4x-10$

Note: When given two points you only need to pick one for the point-slope formula! Best to choose the positive one so you don't have to deal with the negatives!
