Answer:

x=0

y=-14

Step-by-step explanation:

If the equation is y=2x-14,

If x=0,

enter x into the equation

y=2(0)-14

y=0-14

y=-14

find the equation of a straight line passing through the point(4,5) and equally inclined to the lines 3x = 4y +7 and 5y= 12x +6

galina1969 [7]

<span>First we have to determine the slope of each lines by transforming to the slope-intercept form:

y=(3x-7/)4; m2= ¾y=(12x+6)/5, m3 = 12/5

The formula to be used in the proceeding steps is a=tan^-1(m1-m2)/1+m1m2=tan^-1(m1-m2)/1+m1m2
substituting, a=tan^-1(m1-3/4)/1+3m1/4=tan^-1(m1-12/5)1+12m1/5) =>(4m1-3)/(4+3m1)=(5m1-12)/(5+12m1)m1 = -1applying this slope

y -y1 = m(x-x1)
when y1 = 5 and x1 = 4 then,
y - 5 = -1(x-4)
y = -x +4+ 5 ; y = -x +9</span>

Find the slope of the line that passes through (2, 5) and (6,4).

ElenaW [278]

Answer:

The slope of the line is $\frac{1}{-4}$ .

Step-by-step explanation:

We use the formula change in y over change in x to find the slope:

$\frac{5-4}{2-6}$

Then we simplify:

$\frac{1}{-4}$

The slope of the line is $\frac{1}{-4}$ .

4x + 7 = 23slove this

Juli2301 [7.4K]

Given:

4x + 7 = 23

Let's solve for x.

First Step:

Subtract 7 from both sides

4x + 7 - 7 = 23 - 7

4x = 16

Next Step:

DIvide both sides by 4

$\begin{gathered} \frac{4x}{4}=\frac{16}{4} \\ \\ x\text{ = 4} \end{gathered}$

ANSWER:

x = 4
