How do I find B in y=mx+b?

1 answer:

3 0

If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.

An example of the equation would be

y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept

Bob traveled 90 miles which was 83 1 3 % of his trip.<br> How long was the trip?

lina2011 [118]

Total journey of bob was 108 miles .

<u>Step-by-step explanation:</u>

Here we have , Bob traveled 90 miles which was 83 1 3 % of his trip. We need to find How long was the trip .Let's find out:

According to question , Bob has traveled a distance of :

⇒ $Distance = 90miles$

Which is $83\frac{1}{3}\%$ of his journey . So , Let total miles be x , So we have following equation framed according to question as :

⇒ $\frac{83\frac{1}{3} x}{100} =90$

⇒ $\frac{83\frac{1}{3} x}{100}(100) =90(100)$

⇒ $\frac{83(3)+1}{3} x=90(100)$

⇒ $\frac{250}{3} x=9000$

⇒ $x=9000(\frac{3}{250} )$

⇒ $x=108miles$

Therefore , Total journey of bob was 108 miles .

(2x +1°) + (- 10°) = 90°<br>what are the measures of the 2 angles?

LenKa [72]

X-10 + 2x + 1= 90°
you combine like terms:
x+2x= 3x and -10 + 1 = -9
So,
3x - 9 = 90
+9 +9
3x=99
Divide by 3,
x= 33
First Angle: x-10 (plug in 33 for x)
33-10 = 23°
Second Angle: 2x + 1 (plug in 33 for x)
2(33)+1
66+1= 67°
To Check if it’s correct and make a 90° angle:
Add 67° plus 23° which equals 90°
First angle: 23°
Second angle: 67°
Hope that help!!

What is the solution to -41-2x + 6 = -24?

xeze [42]

Hello!

-41 - 2x + 6 = -24 <=>

<=> -35 - 2x = -24 <=>

<=> -2x = -24 + 35 <=>

<=> -2x = 11 <=>

<=> x = -11/2 or -5.5

Good luck! :)

Larry Mitchell invested part of his $36,000 advance at 7% annual simple interest and the rest at 2% annual simple interest. If h

The amount invested at each rate

Investment at 7% = $25000

Investment at 2% = $11,000

<h3>What is investment?</h3>

Investment definition is an asset acquired or invested in to build wealth and save money from the hard earned income or appreciation.

Given:

Larry Mitchell invested = $36,000 at 7% annual simple interest

the rest at 2% annual simple interest.

Total investment = 36000

let the investment at 7% is x

then, invested at 2% = 36000 - x

Total interest earned = $1,970

Simple interest = principal * rate * time

Investment at 4%:

(x * 0.07) + [(36000 - x) * 0.02] = 1970

0.07x + 720 - 0.02x= 1970

0.05x = 1970-720

0.05x = 1250

x= 25000

Hence,

Investment at 7% = $25000

Investment at 2% = $36,000 - $25000 = $11,000
