Simplify the following expression by combining like terms
4 + 5x + 2 =
Answer:
5x + 6
Step-by-step explanation:
4 + 2 is 6 and there is no other number with x so you leave the 5x alone

Select ALL equations that are functions.
functions can't be with exponents -
the correct answers are b,c,d
Answer:
These 3:
y = 2, y = 1/2x + 5, y = x
Step-by-step explanation:
Y can't be squared that would give a sideways function, that doesn't pass the vertical line test
A city bus collected $1,140 in fares on a given day. The regular fare is $1.50, and the reduced fare is $0.75. If 1,042 total fares were paid, which system of linear equations can be used to find x, the number of regular fares paid, and y, the number of reduced fares paid?
Answer:
x + y = 1042
1.50x + 0.75y = 1140
Step-by-step explanation:
If there was a total of 1,042 fares paid then x + y would be equal to that because x is the number of regular fares paid and y is the number of reduced fares paid.
If there was a total of $1,140 made from the fares then we can use 1.50x + 0.75y. We put the 1.5 in front of the x because each fare paid costs $1.50, same with Y each reduced fare paid is $0.75. So both of those need to be added up to get $1,140.

The middle number is -9 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -9
Multiply together to get 8
Can you think of the two numbers?
Try -1 and -8:
-1+-8 = -9
-1*-8 = 8
Fill in the blanks in
(x+_)(x+_)
with -1 and -8 to get...
(x-1)(x-8)
15. Let's solve your equation step-by-step.
(x−2)(x−3)=2
Step 1: Simplify both sides of the equation.
x2−5x+6=2
Step 2: Subtract 2 from both sides.
x2−5x+6−2=2−2
x2−5x+4=0
Step 3: Factor left side of equation.
(x−1)(x−4)=0
Step 4: Set factors equal to 0.
x−1=0 or x−4=0
x=1 or x=4

Find the distance between (1,1) and (13,6)
Answer:
The distance is 13 units
Step-by-step explanation:
13 - 1 = 12
6 - 1 = 5
12² + 5² = c²
144 + 25 = c²
√169 = c
c = 13
(I could have used the distance formula, but the pythagorean theorem is shorter for this problem)
Chris and Eric are competing on a game show. Together they answer 22 questions correctly. Chris’ score was 8 less than twice Eric’s score. How many did each of the guys answer correctly?
Answer:
eric = 15
chris 7
Step-by-step explanation:
Let the questions Chris answered correctly be represented by c
Let the questions Eric answered correctly be represented by e
They both got 22 questions right. This can be represented by this equation :
c + e = 22 --- eqn 1
Chris scored 8 less than Eric. This can be represented by this equation :
c = e - 8 --- eqn 2
Substitute for c in eqn 1
e - 8 + e = 22 .
collect like terms
2e = 30
solve for e
e = 15
Substitute for e in eqn 2
c = 15 - 8 = 7

Step-by-step explanation:
4x^4+12x^2+8 solve ✖➖➕➗
Step-by-step explanation:
Simplifying 4x4 + -12x2 + 8 = 0 Reorder the terms: 8 + -12x2 + 4x4 = 0 Solving 8 + -12x2 + 4x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4'. 4(2 + -3x2 + x4) = 0 Factor a trinomial. 4((1 + -1x2)(2 + -1x2)) = 0 Factor a difference between two squares. 4(((1 + x)(1 + -1x))(2 + -1x2)) = 0 Ignore the factor 4.
Subproblem 1
Set the factor '(2 + -1x2)' equal to zero and attempt to solve: Simplifying 2 + -1x2 = 0 Solving 2 + -1x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x2 = 0 + -2 -1x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1x2 = -2 Divide each side by '-1'. x2 = 2 Simplifying x2 = 2 Take the square root of each side: x = {-1.414213562, 1.414213562}
Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1
Subproblem 3
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1
Solution
x = {-1.414213562, 1.414213562, -1, 1}
