Answer:

[tex]y=\frac{1}{2}x+\frac{3}{2}[/tex]

Step-by-step explanation:

Let's write [tex]-2x+4y=8[/tex] to slope-intercept form.

We do this by solving for [tex]y[/tex]

[tex]-2x+4y=8\\[/tex]

Add 2x to both sides

[tex]4y=8+2x[/tex]

Divide both sides by 4

[tex]y=\frac{1}{2} x+2[/tex]

Now that we have that equation in slope-intercept form, the question wants us to find a line that is parallel to it that passes the point (-5, -1).

A line is parallel to another line is they have the same exact slope.

The slope is [tex]\frac{1}{2}[/tex].

Slope-intercept form: [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.

So, let's see what we have here so far.

[tex]y=\frac{1}{2}x +b[/tex]

All we have to do is find [tex]b[/tex].

The question wants the line to pass the point (-5, -1).

Let's plug that point in.

[tex]-1=\frac{1}{2} (-5)+b\\-1=\frac{-5}{2}+b\\\frac{3}{2} =b\\[/tex]

We have all the information needed to finish this problem!

So, the line that is parallel to [tex]-2x+4y=8[/tex] and passes through the point (-5, -1).

[tex]y=\frac{1}{2}x+\frac{3}{2}[/tex]

Answer:

No

Step-by-step explanation:

Use 2/5...

2 times 2 is 4

5 is greater than four

but 4/5 and 2/5 cannot be replaced with 0

Hence this claim is busted

Answer:

  ∠E = 156°

Step-by-step explanation:

The sum of angle measures in a pentagon is 540°, so we have ...

  95 +(7x -4) +90 +(9x -6) +(3x +23) = 540

  19x +198 = 540

  19x = 342 . . . . . . . subtract 198

  x = 18 . . . . . . . . . . .divide by 19

Then the measure of angle E is ...

  ∠E = (9x -6)° = (9·18 -6)°

  ∠E = 156°

Answer:

Step-by-step explanation:

The slope is the ratio of "rise" to "run". The "rise" is the vertical distance between two points; the "run" is the corresponding horizontal distance.

Here, we see point A is (0, 3) and point B is (1, 2). Then the "rise" is 2 -3 = -1, while the "run" is 1 - 0 = 1. The slope is the ratio ...

  m = rise/run = -1/1 = -1

The slope of the line is -1.

__

The point A is the y-intercept, where the line crosses the y-axis. It tells us the value of y is 3 when x=0. So, we can write the equation in slope-intercept form as ...

  y = mx + b . . . . . where m is the slope (-1) and b is the y-intercept (+3)

  y = -x +3

Option D is the correct answer

Answer:

B: 7t(8s - 3)

Step-by-step explanation:

Method 1: check by expanding each of them

A: 7(8st - 3t)=56st-21t

B: 7t(8s - 3)=56st-2t

C: 3t ( 18s - 7)=54st-21t

D: 7s ( 8t - 3t)=56st-21st

Method 2: the common factors of 56st and 21t is: 7t

56st/7t=8s

-21t/7t=-3

56st-21t=7t(8s-3)

Answer:

Step-by-step explanation:

-8/32 = -1/4

The equation is : y = -1/4 x

Now they say, x = 28 so substitute x as 28 and solve

for when y = -5, substitute -5 as y and solve

Do this for all

Answer:

x = -10

Step-by-step explanation:

First, determine the slope of the answer. The x-axis is a horizontal line, thus the new line must be vertical. All vertical lines are represented by the equation x = a number. That number represents the x-value of all the points the vertical line passes through.

So, since the line passes through (-10, -1), take the x-value of that point and put it into that equation. Thus, x = -10.

Step-by-step explanation:

step 1. 10t + 15 - 3t < 16 (distributive property)

step 2. 7t +15 < 16 (combine like terms)

step 3. 7t < 1 (subtract 15 from both sides)

step 4. t < 1/7 ( divide both sides by 7.
