(5x +2) + (4x -5)
Remove the parenthesis:
5x + 2 + 4x -5
Now combine the like terms:
5x + 4x = 9x
2 - 5 = -3
Put the two terms back together to get: 9x-3

PLease answer this!!!
Answer:
the answer is -5
Step-by-step explanation:
simply put the slope is going down one unit so that would me that for every one year equals 5lb so the would make the ratio 5/1 and when we simply that we get -5 for the first year or range they want us to answer.(And its negative because the slope is going down for the range they give us)

How far is `75\%` of a `2,000`-kilometer trip?
Answer:
1,500 kilometers
Step-by-step explanation:
To find 75% of 2,000, multiply 2,000 by .75. That gets us 1,500. That means 75% of a 2,000 kilometer trip is 1,500 kilometers.
Answer:

Step-by-step explanation:
-2n divided by 3 + (4n - n), when n = 6
Step-by-step explanation:
Divisor = -2n = -2 * 6 = - 12
Dividend = 3 + ( 4 * 6 - 6) = 3 + 18 = 21
Now
21 / -12
dividing numerator and denominator by 3
= - 7 / 4
Step-by-step explanation:
= -2n
= -2×6
= -12
again,
=3+(4n-n)
= 3+4×6-6
=3+24-6
=21
now,
= -12
21

Answer:
Step-by-step explanation:
From the given information:
We learned that it is possible that all entities can be in one of two states i.e. 0 or 1. Thus, all 5 entities can either be 0 or 1 (2 states).
∴
Number of outcomes = 2 × 2 × 2 × 2 × 2
= 2⁵
= 32
b)
All the outcomes of W = {(1, 1, x₃, x₄, x₅) (x₁, x₂, 1, 1, x₅) (1, x₂, 1, x₄, 1)}
Using the equation ŷ = 2.6 − 3.1x, what is the predicted value if x is 4.3?
Select one:
a. −10.73
b. 10.73
c. 15.93
d. −15.93
e. 0.54
Work Shown:
Plug x = 4.3 into the equation given
ŷ = 2.6 − 3.1x
ŷ = 2.6 − 3.1(4.3)
ŷ = 2.6 − 13.33
ŷ = -10.73
Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.

If Y varies directly with X,
find Y when X=24, if Y = 5
when X= 30.
Answer:
Y=4 when X =24
Step-by-step explanation:
If Y varies directly with X, find Y when X=24, if Y = 5 when X= 30.
We can write:
[tex]Y\:\alpha\: X\\Y=kX[/tex]
Where k is known as constant of proportionality
Now, we are given: Y = 5 when X= 30.
We can find value of k
[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]
Now, we will find Y when X = 24
and k=1/6
[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]
So, Y=4 when X =24.

A label is twice as long as it is wide. If the length of the label is 10 cm, find the
area of the label.
O 20 square centimeters
O 50 square centimeters
O 60 square centimeters
O 70 square centimeters
Answer:
50 square centimeters
Step-by-step explanation:
Long means length, and we know the length of the label, 10 centimeters. That means the width is half of 10 centimeters, or 5 centimeters. Now, we multiply 10 and 5 to get 50. That means the area of the label is 50 square centimeters
y = -2x - 9
6x - 5y = -19
Hey there!
y = -2x - 9
6x - 5y = -19
We're going to label the first equation as "1" and the second equation as "2." Now, in order to find the values of "x" & "y," we need to even out the equations by placing their "x" and "y" markers on the same side of the equal sign.
Let's start off by adding 2x to both sides of equation 1.
1) y + 2x = -2x - 9 + 2x
Simplify.
Equation 1 is now: 2x + y = -9
Now, we need to multiply equation 1 equations by "3" in order to create "6x" in both equations. This helps us find the value of "y" because it cancels out the "x" in both equations.
1) (2x + y = -9) × 3
Simplify.
1) 6x + 3y = -27
2) 6x - 5y = -19
Now that our equations are lined up, we can subtract equation 2 from equation 1.
6x - 6x = 03y - (-5y) = 3y + 5y = 8y-27 -(-19) = -27 + 19 = -8Let's put this all together now.
8y = -8
Divide both sides by 8!
8y ÷ 8 = -8 ÷ 8
Simplify.
y = -1Now that we have the value of y, we can easily plug it into one of our equations to get our "x" value.
Equation 1: y = -2x - 9
Plug in "-1" for "y."
-1 = -2x - 9
Add 9 to both sides
-1 + 9 = -2x - 9 + 9
Simplify.
8 = -2x
Divide both sides by -2.
8 ÷ -2 = -2x ÷ -2
Simplify.
-4 = xTherefore, x = -4 & y = -1
(-4, -1)Hope this helped! :)
Answer:
x = - 4
y = - 1
Step-by-step explanation:
y = -2x - 9
2x + y = - 92x + y = -9 (× 3)
6x - 5y = -19
______________
Elimination
6x + 3y = - 27
6x - 5y = - 19
____________ _
8y = - 8y = - 8/8y = -1Solution for x :
Substitution
6x - 5y = -19
6x - 5(-1) = -19
6x + 5 = - 19
6x = - 19 - 5
6x = - 24
x = -24/6
x = -46x - 5y = - 19
6(-4) - 5(-1) = - 19
-24 + 5 = - 19
-19 = - 19
