Step 1: Define Systems
4x - 3y = -20
-x - 8y = 5
Step 2: Rewrite Systems
-x - 8y = 5
[Addition Property of Equality] Add 8y on both sides: -x = 8y + 5[Division Property of Equality] Divide -1 on both sides: x = -8y - 5Step 3: Redefine Systems

x = -5
y = 0
Step-by-step explanation:
4x-3y=-20
-x-8y=5 then x = 8y-5
substitute for x
4(8y-5)-3y = -20
32y-20-3y = -20

3x + 2(4x - 4) = 3
Anyone know the answer?
Answers
Answer:
x=1
Step-by-step explanation:
3x+2(4x-4) = 3
3x+8x-8 = 3
11x-8 = 3
11x = 11
x = 11/11 = 1
The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1
The given expression is,
⇒ 3x + 2 (4x- 4) = 3
We can simplify by apply distributive property and combine like term,
⇒ 3x + 2 (4x- 4) = 3
Apply distributive property,
⇒ 3x + 8x - 8 = 3
Combine like term,
⇒ 11x - 8 = 3
Add 8 both side,
⇒ 11x = 3 + 8
⇒ 11x = 11
Divide by 11,
⇒ x = 11 / 11
⇒ x = 1
Therefore, The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1

bob wants to sub 3x + y = 13 into 4x +3y = 6 he needs to do what to get this
Answers
Answer:
x = 6.6, y = -6.8
Step-by-step explanation:
Subtract 3 x from both sides of the equation.
y = 13 - 3x
4x + 3y = 6
Replace all occurrences of y with 13 − 3 x in each equation.
-5x + 39 = 6
y = 13 - 3x
Solve for x in the first equation.
x = [tex]\frac{33}{5}[/tex] or 6.6
Replace all occurrences of x with 6.6 in each equation.
y = [tex]-\frac{34}{5}[/tex] or - 6.8

Why is it easier to use regression to predict the behavior of an index versus an individual stock?
Answers
Hello, I am BrotherEye
Answer:
Regression models are predictive tools. If you want to use them to predict the behavior of an individual, you must set "behavior" as your dependent variable, and you must have indicators and measures for such. You must also identify your explanatory or independent variable likewise you must have indicators and measures for such.
If you have built your model on the basis of collected data, you will be able to predict the value of behavior given a value of the explanatory variable.

Answer:
40 ft by 85 ft
Step-by-step explanation:
The total length of the three "vertical" partitions is ...
3x = vertical partitions
The total length of the horizontal sides is ...
2(x +(x +5)) = 4x +10
Then the perimeter is ...
P = vertical partitions + horizontal sides
290 = 3x +4x +10
280 = 7x
x = 40
2x+5 = 85
The overall dimensions are 40 ft by 85 ft.
The time, t, for am ice cube to melt. is inversely proportional to the temperature, T, of the water the ice cube is placed. If it takes an ice cube 2 minutes to melt in 75f water, how long will it take an ice cube of the same size to melt in 80f water?
Answers
Answer:
15/8 minutes
Step-by-step explanation:
The inverse relationship implies the following equation.
[tex]t=\frac{k}{T}[/tex]
where k is a constant.
You are given a t and T that go together, so
[tex]2=\frac{k}{75}[/tex]
This implies that k=150. Now you know that the relationship is
[tex]t=\frac{150}{T}[/tex]
Now substitute 80 for T to get the answer.
[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]
minutes.
It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

6x²-12x-25=-7

Answers
Vertex: (1, -24)
Explanation:
6x²-12x-25=-7
6x²-12x-18=0
a=6, b=-12, c=-18
Formula of axis of symmetry: x=-b/2a
x=-b/2a
x= -(-12)/2(6)
x= 12/12
x= 1
Vertex: (1,?)
Sub x= 1 into the equation,
6(1)² - 12(1) - 18 = y
6 - 12 - 18 = y
y = -24
Answer:
Step-by-step explanation:
-b
The axis of symmetry can be calculated using this formula: x = ------
2a
-(-12)
which in this case is x = ---------- = 1. The axis of symmetry is the vertical
2(6) line x = +1
Thus, x = 1 is the x-coordinate of the vertex. Normally we'd find the y-coordinate by evaluating the function at x = 1. Unfortunately your
6x²-12x-25=-7 does not have the form of a quadratic function; such a function does not have the " = " sign in it.
Example: Suppose we have 6x²-12x-25 = f(x) and we evaluate this function at x = 1: f(1) = 6(1)^2 - 12(1) - 25 = -31, which (in this example)
leads to the vertex (1, -31).
