Consider the equation −8x−5y=−10
A line parallel to the above line would have a slope of
A line perpendicular to the above line would have a slope of
Please Help!!
Answer:
Explanation :
The slope of the line with the equation -8x - 5y= -10 is -8/5 so the line parallel to it will have a slope of -8/5 because parallel limes have the same slope.
The line perpendicular to it will have a slope of 5/8. This is because the slopes of perpendicular lines add up to -1.
Hope this help
Find the equation of the line perpendicular line displayed below that passes through the point (-3,2). Explain your process. Express your answer in point-slope form

Answer:
y -2 = 1/4(x +3)
Step-by-step explanation:
Process: find the negative reciprocal of the slope of the line shown and put the appropriate values into the point-slope equation.
__
The slope of the given line can be found as the ratio of rise to run between the marked points.
m = rise/run = -8/2 = -4 . . . . counting grid squares
The desired line has a slope that is the opposite reciprocal of this:
m' = -1/m = -1/-4 = 1/4
The point-slope equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
Then the desired line with slope 1/4 through point (-3, 2) has equation ...
y -2 = 1/4(x +3)
Given: g(x) = -4x and h(x) = 4x +3
Find: g(h(x+1))
Answer:
-16x-28
Step-by-step explanation:
h(x+1)= 4(x+1)+3 = 4x+7
g(h(x+1))= -4[4x+7] = -16x-28

Answer:
d
Step-by-step explanation:
2*4.5=9
scale1:30
=9*30 =270
Convert to actual scale based on proportion of 1:30
4.5 x 30 = 135 inches
2 x 30 = 60 inches
135 x 60 = 8100 inches^2 though we need this in feet and because we solved for area we need to divide by 12in^2*12in*^2
8100/144 = 56.25 or roughly 56 ft^2

(18 - 3)2 = ?
show your work
help me pls ty
Answer: 30
Step-by-step explanation:
18 - 3 is in the parenthesis so you have to solve that first. it’s 15 so the equation would then become (15)2 which is equal to 15 times 2. 15 times 2 equals 30.

Prove: [tex]\frac{a}{b}[/tex] = \frac{c}{d}[/tex], then[tex]\frac{a+b}{b} = \frac{c+d}{d}[/tex]. show work pls :)
Step-by-step explanation:
[tex]\dfrac{a}{b} = \dfrac{c}{d}[/tex]
Add 1 to both sides of the equation:
[tex]\dfrac{a}{b} + 1 = \dfrac{c}{d} + 1[/tex]
Note that
[tex]\dfrac{a}{b} + 1 = \dfrac{a + b}{b}[/tex]
Likewise,
[tex]\dfrac{c}{d} + 1 = \dfrac{c + d}{d}[/tex]
Therefore,
[tex]\dfrac{a + b}{b} = \dfrac{c + d}{d}[/tex]

Using the Principle of Mathematical Induction, prove that . n ^2 − n is even for n ≥ 1
Base case: if n = 1, then
1² - 1 = 0
which is even.
Induction hypothesis: assume the statement is true for n = k, namely that k ² - k is even. This means that k ² - k = 2m for some integer m.
Induction step: show that the assumption implies (k + 1)² - (k + 1) is also even. We have
(k + 1)² - (k + 1) = k ² + 2k + 1 - k - 1
… = (k ² - k) + 2k
… = 2m + 2k
… = 2 (m + k)
which is clearly even. QED

A missile was fired from a submarine from 220 feet below sea level. If the missile reached a height of 10400 feet before exploding, what was the change in the altitude of the missile?
Answer:
10,620
Step-by-step explanation:
Since it reached a height of 10,400 before exploding and was 220 feet below sea level we need to add the two numbers together to get the total change in altitude.
You can think of it as sea level = 0 so 220 feet below sea level is -220 and 10,400 above sea level is +10,400 so what's the difference between the two.
Finding the Difference
10400 - (-220)
= 10400 + 220
= 10620

One more than twice a number is 11. What is the number?
hi <3
we can call the unknown number 'n'
lets form an equation
2n + 1 = 11
subtract 1 from both sides:
2n = 10
divide both sides by 2:
n = 5
the number is 5
