How do I convert standard form to point slope

Fittoniya [83]

The point-slope form:

$y-y_1=m(x-x_1)$

$(x_1,\ y_1)$ - given point

$m$ - given slope

The standard form:

$Ax+By=C$

$y-y_1=m(x-x_1)$ <em>use distributive property</em>

$y-y_1=mx-mx_1$ <em>add $y_1$ to both sides</em>

$y=mx-mx_1+y_1$ <em>subtract $mx$ from both sides</em>

$-mx+y=-mx_1+y_1$ <em>change the signs</em>

$mx-y=mx_1-y_1$

Write 2350 million in standard form

AleksAgata [21]

we know that

<u>Standard Form</u> is also known as Scientific Notation, is a method of writing numbers that accommodates value excessively large or small to be suitably written in Standard Decimal Notation

in this problem we have

$2,350\ million$

Remember that

$1\ million=1,000,000$

so

$2,350\ million=2,350*1,000,000=2,350,000,000$

<u>convert to standard form </u>

$2,350,000,000=2.35*10^{9}$

therefore

<u>the answer is</u>

$2.35*10^{9}$

Answer for: -10 = 10 = 7m. m =<br><br> •0<br> •7 <br> •10<br> •11

wel

Answer:

Ok so your answer should be m = 0

Step-by-step explanation:

the explanation is to Rewrite the equation as − 10 +7 m = − 10 .− 10 + 7 m = − 10

Move all terms not containing m

to the right side of the equation.

7 m = 0

Divide each term by 7

and simplify.

m = 0

i hope this can help

The height of a trapezoid is 8 inches and its area is 48 in.² one base of a trapezoid is 6 inches longer than any other base wha

Mkey [24]

A = (B+b)·h/2 = 48 and B=b+6

2·48 = (b+6+b)·8
12 = 2b + 6
6 = 2b
b = 3 <span>inches
B = 9 </span><span>inches</span>
