11PTS Can Anyone Help Me With These 2 Questions.

Answers

Answer 1

Answer:

N.14: No Solution for both N.15: x=17, LP=34, and LN=34

Step-by-step explanation:

N.14:

2x+12=2x-64 (subtract 2x from both sides)

12=-64

Therefore No Solution Because 12 doesn't equal -64

N.15:

4x-34=2x (subtract 4x from both sides)

-2x=-34 (Divide both sides by -2)

x=17

LP=4(17)-34 (Substitute x for 17)

LP=68-34

LP=34

LN=2(17) (Substitute x for 17)

LN=34

Find the equation of the line that contains the points (-5, 0) and (-3, 4)

Answers

Answer:

y = -1/2x - 5/2

Step-by-step explanation:

With points (-5,0) and (-3,4), we need to find the slope first.

[Find slope of points]

Using slope formula m = (Y2 - Y1) / (X2 - X1)

Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2

[Use point-slope formula]

(y-y0) = m(x-x0)

Using points: (y - 0) = -1/2(x - -5)

Finally: y = -1/2x -5/2

The measure of angles in a triangle are in a ratio of 2:3:4. What are the measures of the angles?

Answers

Answer:

The angle measures are 40°, 60°, and 80°.

Step-by-step explanation:

When we are given this problem, we need to know that

There are three angles in a triangle.These angles add up to equal 180°.

With this ratio, these angles must add up to equal 180°. Therefore, we can set up an equation and add an x-variable to each of the numbers. We then set this equal to 180.

[tex]\text{2x + 3x + 4x = 180}\\\\\text{9x = 180}\\\\\text{x = 20}[/tex]

Now, we need to find the measures of the angles. The angles are the parts of the ratio multiplied by the value of x.

[tex]\text{2(20) = 40}\\\\\text{3(20) = 60}\\\\\text{4(20) = 80}[/tex]

So, our three angles measures should be 40°, 60°, and 80°. We can check this by adding up these three values and seeing if the sum equals 180°.

[tex]\text{40 + 60 + 80 = 180}\\\\\text{100 + 80 = 180}\\\\\text{180 = 180}[/tex]

Because this is true, our angle measures are 40°, 60°, and 80°.

Answer:

summary

Step-by-step explanation:

Answer: Choice C

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)

============================================

Explanation:

The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.

The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,

slope = rise/run = (change in y)/(change in x)

Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.

I forgot about this one! Sorry... As always, I will give brainliest, five stars thanks, and everything! DUE TODAY!! Please help!

Answers

Answer:

the slope is -1/4

Step-by-step explanation:

Calculate the slope using this formula: y2-y1/x2-x1

There are two points indicated on the graph; use them

those points are:

(-8,7) and (8,3)

now, label the points

x1=-8

y1=7

x2=8

y2=3

now, plug the numbers into the equation

3-7/8-(-8)

-4/16

-1/4=m (slope)

(Other: Use a pencil and paper. Find the integer that would represent the change in the amount if Miriam deposits $13 into her bank account once each day for five days. Explain the difference between the integer for the withdrawals and the integer for the deposits.)

Answers

Answer: $-65 and $65

Difference=130

Step-by-step explanation:

You just multiply 13 and 5 because it is 13 dollars for 5 days. It’s the same answer for both problems except one is a negative and one is a positive. To find the difference between both integers you add 65 and 65 to get an integer of 130.

Answer:

Answer:

x= 29/11 or y= 25/11

Step-by-step explanation:

2x - y= 3 ...........equation 1

x + 5y= 14 ............equation 2

Make x the subject of the formula in equation 2

x= 14 - 5y ..............equation 3

Substitute x=14 - 5y in equation 1

2(14- 5y) - y=3

28 - 10y - y=3

Collect like terms

-10y - y=3 - 28

-11y= -25

divide both sides by coefficient of y

-11y/-11 = -25/-11

y= 25/11

Substitute y= 25/11 in equation 3

x=14 - 5(25/11)

x= 14 - 125/11

x= 29/11

Step-by-step explanation:

Answer:
x= 29/11 or y= 25/11
Step-by-step explanation:
2x - y= 3 ...........equation 1
x + 5y= 14 ............equation 2
Make x the subject of the formula in equation 2
x= 14 - 5y ..............equation 3
Substitute x=14 - 5y in equation 1
2(14- 5y) - y=3
28 - 10y - y=3
Collect like terms
-10y - y=3 - 28
-11y= -25
divide both sides by coefficient of y
-11y/-11 = -25/-11
y= 25/11
Substitute y= 25/11 in equation 3
x=14 - 5(25/11)
x= 14 - 125/11
x= 29/11

The vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of the vertical line is undefined, therefore there is no point slope form as such.
