Answer 1

Answer:

See the explanation

Explanation:

Hello! Your figures are missing, so I could help you in a general way. The Slope-intercept form of the equation of a line is given by the form:

$y=mx+b \n \n \n m:Slope \n \n b=y-intercept$

Case 1:

$m>0$

If the slope is positive, we will have a line as the form illustrated in figure 1. So as x increases y also increases.

Case 2:

$m<0$

If the slope is negative, we will have a line as the form illustrated in figure 2. So as x increases y decreases.

Case 3:

$m=0$

If the slope is zero, we will have a line as the form illustrated in figure 3. here we have a constant function.

Case 4:

m: undefined

If the slope is undefined, we will have a line as the form illustrated in figure 4.

Best Method using system of equations

x=4y+8
2x-8y=-3

Answers

In this case, since one equation is in the form of x=, substitution would be best for this problem. Simply plug in 4y + 8 in place of x in the second equation, solve for y, then plug that value into the first equation to find x.

X=4y+8
2x-8y=-3

lets use the substitution method
2x-8y=-3
2(4y+8)-8y=-3
8y+16-8y=-3
16 is not equal to -3 so lets try elimination

x=4y+8
2x-8y=-3

xhange the 1st equation to standard for
x-4y=8
2x-8y=-3

multiply the 1st equation to remove x
2x-8y=8
2x-8y=-3
0 is not equal to 11

therefore we cannot solve using both equations so te question's answer is undefined

First, evaluate 200+78÷ 4x2. Which equals 239. Now, 10% of 239 = 23.9

What is the percent of increase for a population that changed from 438,000 to 561,000?

Answers

To get the answer we can use proportion. We know that 438000 its 100% and we want to know how much its 561000.
438000 ------------ 100%
561000 ------------ x
Crossmultiply now
438000*x=561000*100%
438000x=56100000 /:438000 (divide both sides by 438000)
x=128%
Finally we have to subtract 128%-100%=28% to get percent of increase.
The answer is 28%.

find out how much 561000 goes over 438000, which would be 123000. then you divide to find out the ratio or percentage of the increase from 438000 would be. 123000/438000=.2808219178 so .28 so 28%.

The measure of an angle is 176.9°. What is the measure of a supplementary angle?

Answers

Here, it is easier to add to 176.9 to get to 180 degrees. First, make it a whole number by adding 0.1, which gives you 177. Then it takes 3 degrees to get to 180, so the answer is 3.1 degrees.

Hope this helps.
