Mathematics
1 answer:
AVprozaik [17]3 years ago
4 0

Answer:

y = 2x + 7

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Slope-Intercept Form: y = mx + b

We are only focusing on the line of best fit.

Step 1: Find 2 coordinates

(0, 7) y-intercept

(2, 11) random

Step 2: Find slope <em>m</em>

m = (11 - 7)/(2 - 0)

m = 4/2

m = 2

y = 2x + b

Step 3: Rewrite linear equation

y = 2x + 7

Jessica assembles a product that requires the insertion of 3 aluminum pins. She can assemble approximately 15 products per hour.
larisa [96]
If she can make 15 per hour that would mean that each hour she is making 15 cans.

She has 6 hours that means that she will make 90 products.

How To Do The Math: 15<span>×6=90

Since we are finding out how many pins she need and not haw many products we will have to check how many pins she will need per product.

She needs 3 pins per product.

Since she will be making 90 products all we have to do is multiply 90 by 3 which will equal 270.

How To Do The Math:90</span><span>×3=270

Your Answer will be 270 Pins.</span>

One angle has five times as many degrees as another angle. The greater angle has 120 degrees more than the lesser angle. How man
jok3333 [9.3K]

Answer:

b = 30 degrees

a = 150 degrees

Step-by-step explanation:

Let's call <em>a</em> to the first angle and <em>b</em> to the second one. So we have:

a = 5*b  (1)

and it says that the greater angle has 120 degrees more than the lesser angle. So It will be:

a = 120+b (2)

We just need to solve both equations. We can equal both of them.

5b = 120+b

4b = 120

b = 30 degrees

Therefore a = 5*30 = 150 degrees

a = 150 degrees

I hope it helps you!
