Answer:

y =14

Step-by-step explanation:

we know that <a = <b since it is an isosceles triangle

<a = <b = 50

the triangle add to 180 degrees

<a + <b + <c =180

50 + 50 + <c = 180

add like terms

100 + <c = 180

subtract 100 from each side

<c = 180-100

<c = 80

<c = 5y+ 10

80 = 5y+10

subtract 10 from each side

80 -10 = 5y+10-10

80-10 = 5y

70 = 5y

divide by 5

70/5 =5y/5

14 = y

What is an equation of the line that passes through the points (-6, -2) and

den301095 [7]

Answer:

The equation of line is: $\mathbf{4x-3y=-18}$

Step-by-step explanation:

We need to find an equation of the line that passes through the points (-6, -2) and (-3, 2)?

The equation of line in slope-intercept form is: $y=mx+b$

where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding Slope

Slope can be found using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We have $x_1=-6,y_1=-2, x_2=-3, y_2=2$

Putting values and finding slope

$Slope=\frac{2-(-2)}{-3-(-6)}\\Slope=\frac{2+2}{-3+6} \\Slope=\frac{4}{3}$

So, we get slope: $m=\frac{4}{3}$

Finding y-intercept

Using point (-6,-2) and slope $m=\frac{4}{3}$ we can find y-intercept

$y=mx+b\\-2=\frac{4}{3}(-6)+b\\-2=4(-2)+b\\-2=-8+b\\b=-2+8\\b=6$

So, we get y-intercept b= 6

Equation of required line

The equation of required line having slope $m=\frac{4}{3}$ and y-intercept b = 6 is

$y=mx+b\\y=\frac{4}{3}x+6$

Now transforming in fully reduced form:

$y=\frac{4x+6*3}{3} \\y=\frac{4x+18}{3} \\3y=4x+18\\4x-3y=-18$

So, the equation of line is: $\mathbf{4x-3y=-18}$

0.18 in standard form

slamgirl [31]

Answer:

Well.. its already in standard form..

but even if u want u can write it as 8 X 10^(-1)

Step-by-step explanation:

Standard form is used for quite big decimal numbers

like : 0.2356

We can write it as 2.4 X 10^(-1)
