Answer:

5 significant figures

Step-by-step explanation:

looking at the last two digit of the numbers, it multiplication gives, 4*5=20

Remember that the general equation of a line is y=mx+b, where:
m is the slope, and b is the y-intercept; so to find the y-intercept, solve for y and identify b.
Now, to find the x-intercept, just replace y in your line equation with 0, and solve for x
Lets apply those procedures to our two questions:

1. - y-intercept:
-10x+5y=40
5y=10x+40
y= \frac{10x+40}{5}
y=2x+8
Notice that now we have our line equation in the form y=mx+b with m=2 and b=8; sine b is the y-intercept, we can conclude that the y-intercept of our equation is 8.

x-intercept:
First, lets replace y with 0:
0=2x+8
And then, we can solve for x to find our x-intercept:
2x=-8
x= \frac{-8}{2}
x=-4
We can conclude that our x-intercept is -4; thus the correct answer in your list is the fourth one: x-intercept is -4; y-intercept is 8.

2. y-intercept:
5x+4y=80
4y=-5x+80
y= \frac{-5x+80}{4}
y=- \frac{5}{4} x+20
We can conclude that our y-intercept is 20.

x-intercept:
0=- \frac{5}{4} x+20
- \frac{5}{4} x=-20
x=( \frac{4}{5} )(20)
x=16
We can conclude that our x-intercept is 16; thus the correct answer in your list is, once again, the fourth one: x-intercept is 16; y-intercept is 20.

What is the point-slope form of a line with slope that contains the point (-3, 6)?
coldgirl [10]
Point slope
y-y1=m(x-x1)
where you are given the point (x1,y1) and the slope is m

we are given the point (-3,6)
x1=-3
y1=6
y-6=m(x-(-3))
y-6=m(x+3) is the point slope form and we don't kn ow the slope yet

While looking at some reports, a store manager notes that televisions that retail for $475 and up costing customers $513 once th
Mekhanik [1.2K]

The sales tax percentage of the store manager report is 7.41%

<h3>How to solve for the sales tax percentage</h3>

Customers are subject to a charge known as sales tax when they buy goods and services.

It is a pass-through tax, which means you must collect it from clients and send the money to your state or local government. the seller do not contribute sales tax.

The sales tax is first calculated by

= price after tax - price before tax

= 513 - 475

= 38

sales tax percentage is calculated using the formula

= (Tax amount / Price before tax) × 100%

= (38 / 513) * 100

= 7.4074

= 7.41%
