Answer:
0Step-by-step explanation:
The slope of the line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(-2, 8) ⇒ x₁ = -2, y₁ = 8
(-22, 8) ⇒ x₂ = -22, y₂ = 8
So, the slope:
[tex]m=\dfrac{8-8}{-22-(-2)}=\dfrac{0}{-20}=0[/tex]

Write an equation for the line that is perpendicular to Y=-3/7x+4 and passes through (-4,-5)
9514 1404 393
Answer:
y = 7/3x +13/3
Step-by-step explanation:
The equation of the given line is in slope-intercept form (y=mx+b), so we can see the slope (m) is -3/7. The slope of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/(-3/7) = 7/3
The y-intercept of the perpendicular line can be found from ...
b = y -mx
b = -5 -(7/3)(-4) = -15/3 +28/3 = 13/3
Then the slope-intercept equation of the perpendicular line is ...
y = mx +b
y = 7/3x +13/3
_____
Additional comment
You can get there a little faster using the point-slope form of the equation of a line. For slope m and point (h, k) that form is ...
y -k = m(x -h)
For our perpendicular line, the equation is ...
y +5 = 7/3(x +4)

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
Answer:
14.76 cm
Step-by-step explanation:
Use the pythagorean theorem:
a² + b² = c²
Plug in the side lengths and solve for c:
7² + 13² = c²
49 + 169 = c²
218 = c²
14.76 = c
So, the hypotenuse is approximately 14.76 cm

Find the total package price from each store and then calculate how much you"lol save if you purchase the less expensive package
Complete Question:
You're planning to buy a new computer, monitor, and printer for your office. You've received the following prices from two stores:
Store 1 Store 2
Computer: 2,500 Computer: 2,350
Monitor: 595 Monitor: 435
Printer: 398 Printer: 349
Find the total package price from each store and then calculate how much you'll save if you purchase the less expensive package.
Answer:
[tex]Total = 3493[/tex] --- Store 1
[tex]Total = 3134[/tex] --- Store 2
[tex]Saved = 359[/tex]
Step-by-step explanation:
From store 1, the total cost is:
[tex]Total = 2500 + 595 + 398[/tex]
[tex]Total = 3493[/tex]
For store 2, the total cost is
[tex]Total = 2350 + 435 + 349[/tex]
[tex]Total = 3134[/tex]
By comparison: It is cheaper to buy from store 2
Because [tex]3134 < 3493[/tex]
Amount saved is calculated by subtracting the cheaper cost from the expensive cost:
i.e.
[tex]Saved = 3493 - 3134[/tex]
[tex]Saved = 359[/tex]
Perform the operation.
(x^2 + 8x + 8) + (-10x2 + 5x)
Answer:
-9x^2+13x+8
Step-by-step explanation:
Combine like terms-
(x^2 + 8x + 8) + (-10x^2 + 5x)
8x+5x = 13x
(x^2 + 8x + 8) + (-10x^2 + 5x)
-10x^2+x^2 = -9x^2
(x^2 + 8x + 8) + (-10x2 + 5x)
and 8 is just left over, so we put that all together and get...
-9x^2+13x+8

Mr. Turney wrote the value statement "x = 2" on the whiteboard. He asked his students to create an equation or inequality with this value as a solution.
Answer:
Some of the equations can be written as-
1. 2x = 4
2. 3x + 9 = 15
3. x + 5 = 7
4. 5x - 2 = 8
Step-by-step explanation:
Given - Mr. Turney wrote the value statement "x = 2" on the whiteboard.
To find - He asked his students to create an equation or inequality with
this value as a solution.
Proof -
Given that, The value statement is ''x = 2''
We have to find out that equation in such a way that if we solve the equation , we get the value x = 2
There can be infinite many equation that give the value statement '' x = 2''
Some of the equations can be written as-
1. 2x = 4
2. 3x + 9 = 15
3. x + 5 = 7
4. 5x - 2 = 8
And many more.
Verification -
1. 2x = 4
⇒x = [tex]\frac{4}{2}[/tex]
⇒x = 2
Verified
2. 3x + 9 = 15
⇒3x = 15 - 9
⇒3x = 6
⇒x = [tex]\frac{6}{3}[/tex]
⇒x = 2
Verified
3. x + 5 = 7
⇒x = 7 - 5
⇒x = 2
Verified
4. 5x - 2 = 8
⇒5x = 8 + 2
⇒5x = 10
⇒x = [tex]\frac{10}{5}[/tex]
⇒x = 2

What is the value of n?
Please help quick
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15

Find the exact value of the expression: -6 3/5 - (-7 4/15) + 2 1/5
Answer:
Step-by-step explanation:
-6 3/5 - (-7 4/15) + 2 1/5
Combine the first and third terms first
-6 3/5 + 2 1/5 = - 4 2/5
Now deal with the second term
- (- 7 4/15) = 7 4/15
7 4/15 - 4 2/5
7 4/15 - 4 6/15 Add 15/15 to 7 4/15 Subtract 1 from the 7
6 19/15 - 4 6/15
2 13/15

Two parallel lines are cut by a transversal as shown below.
Suppose m∠5 = 104°. Find m∠2 and m∠4.
m∠2 = _°
m∠4 = _°
Answer:
Angle 2 = Angle 4 = 76
Step-by-step explanation:
Here, we want to get the measures of angle 2 and angle 4
From what we have in the diagram, angle 2 and angle 5 are supplementary (meaning they add up to 180)
The reason for this is because both angles are same side interior angles
Thus,
angle 2 + angle 5 = 180
angle 2 = 180 - angle 5
angle 2 = 180 -104
angle 2 = 76
Furthermore, we can see that angle 2 equals angle 4 as they are vertically opposite angles
Thus, angle 2 = angle 4 = 76
