6 0

Step-by-step explanation:

The +7 is the y-intercept

It is where the line starts in your example and is 7 units away from 0

Since the line is decreasing the 3 is negative

It will be understood that population 6,000 billion (6*10^12) in 2017.
If this is not the case, follow the logic and the final number can be adjusted easily.

Mathematical answer:
In 2017: 6,000 billion=6000*10^9 =6*10^12
rate of increase = 1.3% per year (assumed constant)
final year = 2100
Population estimate in 2100
=6*10^12*(1.013^(2100-2017))
=6*10^12*(1.013^(83)
=6*10^12*(2.921352509198383)
=17.528*10^12
=17,528 billion.

Write the slope-intercept form of the line that passes through (-10,17) and (5,-4)
luda_lava [24]

Answer:

y = 7/5 x + 31

Step-by-step explanation:

To find the slope, we need to use the formula

m = (y2-y1)/(x2-x1)

m =(-4-17)/(5- -10)

   = -21/(5+10)

  = 21/15

Divide the top and bottom by 3.

  = 7/5

The slope is 7/5.


Using the point slope form of the equation,

y-y1 = m(x-x1)

y-17 = 7/5 (x--10)

y-17 = 7/5(x+10)

Distribute the 7/5 ths.

y-17 = 7/5 x + 7/5*10

y-17 = 7/5 x +14

Add 17 to each side

y = 7/5 x + 14 + 17

y = 7/5 x + 31


This is in slope intercept form, with the slope  being 7/5 and the y intercept of 31

What would be the answer to x + 22 - 13x greater than or equal to 118
Fynjy0 [20]

Answer:.

x greater than or equal to -8

Step-by-step explanation:

x+22-13x≥118

Collect like terms

x-13x≥118-22

-12x≥96

Divide both sides by -12

-12x/12≥96/-12

x≥96/-12

x≥-8

The answer is x greater than or equal to -8
