What is the equation of the line that passes through the point (2, -4) and has a
slope of 2
Answer:
y = 2x - 8 OR 4 - 2x = -4 - y
Step-by-step explanation:
Use the point-slope form m(x₁-x₂) = (y₁-y₂); m means slope
plug in your numbers:
2(2-x₂) = (-4-y₂)
4 - 2x = -4 - y
or to put it into Y=mx + b:
y = 2x + 8

Which translation vectors could have been used for the pair of figures?
select EACH correct answer
Answer:
The translation vector can be drawn on the coordinate grid or written as
\vec{v}=\langle a,b\rangle
v
=⟨a,b⟩
. For example, a translation vector that moves a figure
3
3
units right and
2
2
units down can be represented mathematically as
\vec{v}=\langle3,-2\rangle
v
=⟨3,−2⟩
, or graphically as
It doesn’t matter where the vector is positioned in the plane. In this figure, the vector starts at
(1,1)
(1,1)
and ends at
(4,-1)
(4,−1)
. But the initial point and terminal point of the vector are irrelevant. What matters is the length of the vector and the direction in which it points, so all you have to look at is how many units the vector moves in the
y
y
-direction and how many units the vector moves in the
x
x
-direction.

5(1+2x)= 5 +10x =10x + 5
Answer:
Yes, they are eqivelant.
Step-by-step explanation:
5(1+2x) and 10x+5
The first step is to set them equal to each other, to see if they are equivelent.
5(1+2x) = 10x+5
Distribute the 5 to both terms in the parentheses by multiplying.
5(1) + 5(2x) = 10x +5
5 + 10x = 10x +5
The communative property of addition proves that these are equal.

Answer:
Image result for 44. Consider all rectangles with an area of 182 square feet. Let's Be the length of one side of such a rectangle a) Express the perimeter as a function of b) Use the graphing calculator to find the dimensions of the rectangle that has the least perimeter. What is the least perimeter?
Divide the area of the rectangle by the width in order to find the length of 14 feet. The perimeter is the sum of the side lengths, which in this case is 14 feet + 4 feet +14 feet + 4 feet, or 36 feet.

13) Rylee had a negative balance of $23 in her bank
account. Her cell phone bill charged this month's balance
of $56. What is Rylee's new balance?
Answer:
-$79
Step-by-step explanation:
If i read that correctly, Rylee had -$23 in her account.
Then, she was charged $56, meaning we have to subtract $56 from -$23. When we do -23 - 56, we get -79. Meaning, Rylee now has a balance of -$79.
Answer:
Step-by-step explanation:
The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Hello there!
We are given the equation:
[tex] \displaystyle \large{ |4x - 1| = 1}[/tex]
Definition/Property
[tex] \displaystyle \large{ |a| = \sqrt{ {a}^{2} } } \\ \displaystyle \large{ |a| = b \longrightarrow a = \pm b} \\ \displaystyle \large{ |a| = \begin{cases} a \: \: (x \geqslant 0) \\ - a \: \: (a < 0) \end{cases}}[/tex]
First, cancel the absolute value sign and write plus-minus beside 1.
[tex] \displaystyle \large{ |4x - 1| = 1} \\ \displaystyle \large{ 4x - 1 = \pm 1} \\ [/tex]
Break in two cases.
[tex] \displaystyle \large{ 4x - 1 = \begin{cases} 1 \\ - 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 1 + 1 \\ - 1 + 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 2 \\ 0 \end{cases}} \\ \displaystyle \large{ x = \begin{cases} \frac{2}{4} \\ \frac{0}{4} \end{cases}}[/tex]
Therefore, x = 0 or 1/2

|3x-8|+7=2
Answer:
No solution
Step-by-step explanation:
To solve first you need to isolate the absolute value sign. Do this by subtracting 7 from each side.
|3x-8| = -5Now an expression inside absolute value bars is set to a negative. Since absolute value makes terms and expressions positive, there is no x-value that could make this true. Therefore, there are no solutions.
[tex]\\ \tt\Rrightarrow |3x-8|+7=2[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=2-7[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=-5[/tex]
Because of absolute vale there is no solution

Write each decimal number as a fraction or mixed number in simplest form?
You're letting x = 0.325325325…, which means
1000x = 325.325325325… (or 325.325, but pretend the underline is actually an overline)
Then the next box you'd fill in with 0.325325325… (or 0.325).
Subtracting these, you have
1000x - x = 325.325325325… - 0.325325325…
999x = 325
Finally, solving for x gives
x = 325/999
What is an equation of the line that passes through the points (1, 8) and (-1, -2)
Answer:
Step-by-step explanation:
(1,8) (-1,-2)
Slope: (-2-8)/(-1-1) = -10/-2 = 5
y -8 = 5 (x - 1)
y - 8 = 5x - 5
y = 5x +3
Find ""k"" so that the 58 unit diagonal of a rectangle can have an aspect ratio of 15:8. Then find the length and width of the rectangle and find its area.
Step-by-step explanation:
The area of any 2-d quadrilateral is equal to the base of the shape times the height, though we can just sub in length and width here. The key bits of information here is the aspect ratio (4:3) and the given area (300 in^2).
So far this gives us L∗W=300in2
Now, the aspect ratio given implies for every 4 inches in length, there will be 3 inches in width. This allows us to factor out a 4 and a 3 from the Length and Width respectively and give them the same constant variable, like so:
4x∗3x=300in2
Now, some might be tempted to go ahead with 12x here, but let’s expand the left side out to see what’s really going on:
4∗x∗3∗x=300in2
From here, let’s resolve like terms Our constants will multiply together and give us 12, and x * x of course gives us x^2 to give us the following:
12x2=300in2
From here, simply divide through by 12 to isolate x on one side,x2=25
And finally take the square root of both sides to work out what your common factor is,
x=5
Now that we have out common factor, let’s plug it back into our original formula to find our Length and Width, like so.
(4∗5)in∗(3∗5)in=300in2
20in∗15in=300in2
Therefore, the Length of our rectangle is 20in, and the Width of our rectangle is 15in
