Answer:

This formula can also be written as $y - {y}_{1} = m\left(x - {x}_{1}\right)$. The standard form of the straight line equation is $y = mx + c$ where $m$ is the gradient and $c$ is the $y$-intercept.

In ΔWXY, if m∠W is five less than three times m∠Y and m∠X is 8 more than m∠W, find the measures of each angles?

yulyashka [42]

Answer:

∡W = 73°

∡X = 81°

∡Y = 26°

Step-by-step explanation:

let 'y' = measure angle Y

let '3y - 5' = measure of angle W

let '3y + 3' = measure of angle X

add all together and set equal to 180

y + 3y + 3y - 2 = 180

7y = 182

y = 26

substitute 26 for y in '3y+3' to find measure of angle X

substitute 26 for y in '3y-5' to find measure of angle W

1. What is the total cost of a $95.00 item with a sales tax of 6%?

Reptile [31]

Since the sales tax is 6%, the object will cost 1.06 (100% + 6%) times the original value.

1.06 × $95.00 = $100.70

The object will cost $100.70.

Let me know if you need any clarifications, thanks!

3ab - 2bc = 12 solve for b

Nikitich [7]

(3ab/b)-(2bc/b)=12/b
3a-2c=12b^-1
(3a-2c)/12=(12b^-1)/12
(3a-2c)/12=b^-1
12/(3a-2c)=b

Write the equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3

Inga [223]

Answer:

The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:

$\mathbf{y=-\frac{2}{3}x+1}$

Step-by-step explanation:

We need to write equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3.

The equation for slope-intercept form is: $y=mx+b$

where m is slope and b is y-intercept.

We are given slope m = -2/3 and we need to find y-intercept i.e b to write equation of line.

Using point (3,-1) and slope m=-2/3 we can find y-intercept i.e b

$y=mx+b\\-1=-\frac{2}{3}(3)+b\\-1=-2+b\\b=-1+2\\b=1$

So, y-intercept b = 1

The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:

$y=mx+b\\\mathbf{y=-\frac{2}{3}x+1}$
