Write equations to solve these problems

Mathematics
1 answer:
dangina [55]2 years ago
6 0

Answer:

Step-by-step explanation:

a) 60 = 50x

x = 60 / 50 = 1.20

1.20(100) = 120%

b 50 = 60x

x = 50/60 = 0.83333....

0.83333(100) = 83.333... % or 83⅓%

what equation in slope intercept form for the line that passes through point (8,-3) and has a y intercept of -2
JulijaS [17]

Answer:

y=-8x-2

Step-by-step explanation:

The formula for slope is y2-y1/x2-x1. Take coordinate (0,-2), which is the y-intercept. We'll call that (y2,x2). Coordinate (8,-3) is (y1,x1). Put that into the formula you get, 0-8/-2-(-3). You get -8/1 which is negative 8. We now have the slope. Slope intercept form equation is y=mx+b. M is slope, so we put our slope in the equation and get, y=-8x+b. B is the y-intercept which is given. So we know that the equation to this line in slope-intercept form is y=-8x-2.

Which table represents a linear function? Which quadratic function is represented by the graph?
IgorC [24]

The first table is a quadratic function while the second table is a linear function.

<h3>How to Interpret Function Tables?</h3>

1) For the first table, we have;

x y

0 5

1 0

2 -3

3 -4

4 -3

x = 2  and x = 4 have same value of y = -3  and as such it will be a Quadratic Function.

y = x²  - 6x + 5

2) For the second table, we have;

x y

2 5

5 14

6 17

8 23

10 29

This table is a Linear function because  slope is same and equal to 3 all through. Thus, the equation is y = 3x - 1  

3) For the third table, we have;

x y

-3 8

-2 4

-1 2

0 1

1 0.5

This is an exponential function because equation can be modelled by;

y = 2⁻ˣ

A decimal number which ends after a finite number of digits after the decimal point is called a _______ decimal. Example: 6.875
AysviL [449]
This kind of decimal is called a terminating decimal, meaning it ends rather than repeating on forever like this one: 4.5555555555...... or the fraction 2/3 when you turn it into a decimal.
