Answer:
C
Step-by-step explanation:
Lines that are parallel AND have different y-intercepts will never intersect each other, therefore will have no solutions.
The only correct choice is C as the lines are parallel and have different y-intercepts which means they'll never intersect each other. All the other choices will have their lines intersect each other at some point.

For each equation, determine if x = 2 is a solution. Explain or show your reasoning.
a.
-2(x – 4) = 4
b.
26

C.
-3.8x = -7.4
4(x - 1) – 3(x - 2) = -8
d.
Answers
B. Yes because 26/2 does equals = 13
C. No because -3.8(2) equals -7.6 and not -7.4
D. No because 4(2-1)-3(2-2) equals 4 and not -8
x=2 is a solution of equations -2(x – 4) = 4 and 26/x=13
What is Equation?Two or more expressions with an Equal sign is called as Equation.
-2(x-4)=4
-2(2-4)=4
4=4
Hence, x=2 is the solution
26/x=13
Now x=2
26/2=13
13=13
Hence, x=2 is the solution
-3.8x=-7.4
Now x=2
-3.8×2=-7.4
-7.6=-7.4
x=2 is not a solution of -3.8×2=-7.4
4(x - 1) – 3(x - 2) = -8
4(2-1)-3(2-2)=-8
4=-8
x=2 is not a solution of -3.8×2=-7.4
Hence, x=2 is a solution of equations -2(x – 4) = 4 and 26/x=13

A company that makes hair-care products had 9,000 people try the new shampoo. Of the 9,000 people, 36 had a mild allergic reaction. Wht percent of the people had a mild mild allergic reaction?
Answers
Answer:
0.4% of the people had a mild allergic reaction.
Step-by-step explanation:
You can find the percent of the people that had a mild allergic reaction using a rule of three as you know that 9,000 people tried the new shampoo which would be the 100% and you can find the percent that represents 36 people:
9,000 → 100%
36 → x
x=(36*100)/9,000
x=0.4%
According to this, the answer is that 0.4% of the people had a mild allergic reaction.

Cameron is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. Let C represent the total cost of the gym membership over t months.
The graph of the function C = 100 +25m is given,
the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
C= 100+25t
Where C represents the total charge,
t represents the number of months as of 25 per month,
And 100 represents the one-time chargeable fee to join.
Thus, the y-intercept of the function is 100 which represents a one-time fee to join.

Round 5949.69836527 to the nearest hundredth.
rounding numbers
Answers
Answer:
It would be 5949.70
Step-by-step explanation:
The hundreds place is the first two number after a decimal point. In this case it would be 6 and 9. Now if were rounding to the hundredths, you would look at the number right after 9 to see if you could round up. That number happens to be an 8, and if that number is greater than 5, than it will round up the number before it. Now since 8 would round up nine, that would make it a 10, but that can not happen, so you would have to round up the first number as well, which would give you .70.

Hence, the highest recorded temperature was 38 degrees.
A hair stylist knows that 87% of her customers get a haircut and 40% get their hair colored on a regular basis. Of the customers who get their hair cut, 24% also get their hair colored. What is the probability that a randomly selected customer gets their hair cut and colored?
0.10
0.21
0.35
0.40
Answers
Answer:
Okay so!
Step-by-step explanation:
for a cut that's .87 and for a color that is .24 so you multiply them together to get the probability for the color which is
.35 or C on edge
The probability that a randomly selected customer gets their hair cut and colored is .
What is probability?Probability is the chance of happening an incident or event. A probability is calculated by the ratio of the possible outcomes to total number of outcomes.
Given, the probability of he customer get a hair cut is = P(A) = 87% = 0.87.
The probability of he customer get their hair colored is = P(B) = 40% = 0.4.
Therefore, the probability of a randomly selected customer get hair cut and hair color is = P(A) × P(B) = 0.87 × 0.4 = 0.35
Therefore, 35% of the total customer get hair cut and color.

Sandy charges each family that she babysits a flat fee of $10 for the night and an extra $5 per child. Which a y = 10x + 5 b y = 5x + 10 c y = -5x + 10 d y = -10x -5
Answers
Answer: B. y = 5x + 10
Step-by-step explanation:
Based on the scenario in the question, you didn't really say what you'll like to calculate but I guess you want to know the equation that can be used to represent the above information.
Let x = the number of children babysit
The amount charged by Sandy can then be written as:
y = 10 + 5(x)
y = 10 + 5x
y = 5x + 10
Therefore, the correct option is B.

x + 2x + 12y + 4 I don't know the answer can someone help me please
Answers
Answer:
The asnwer is 3x + 12y + 4
Answer:
I think you wrote it wrong but if not here
Step-by-step explanation:
Simplifying
2x + -12y = 4
Solving
2x + -12y = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12y' to each side of the equation.
2x + -12y + 12y = 4 + 12y
Combine like terms: -12y + 12y = 0
2x + 0 = 4 + 12y
2x = 4 + 12y
Divide each side by '2'.
x = 2 + 6y
Simplifying
x = 2 + 6y

Luis le dice a su amiga: "Yo tengo ahora el triple de edad que tú tenías, cuando yo tenía la edad que tú tienes ahora". Si entre los dos suman 50 años, ¿cuántos tiene cada uno?
Answers
Answer:
Luis tiene 30 años de edad y su amiga tiene 20 años edad.
Step-by-step explanation:
Cuando Luis tenia 20 años de edad (hace 10 años), su amiga tenia solamente 10 años de edad. Si multiplicamos 10 x 3 nos da como resultado 30, que es la edad actual de Luis.
L + A = 50
3(A - x) = L
L = 50 - A
3A - 3x = 50 - A
4A = 50 + 3x
en este punto podemos probar diferentes alternativas para x:
x = 5, entonces 4A = 50 + 15
A = 16.25 no es factible porque estamos buscando numeros enteros
x = 6, entonces 4A = 50 + 18
A = 17
al reemplazar, nos da una edad de 3(17 - 5) = 36 para Luis, pero 36 + 17 = 53
x = 8, entonces 4A = 50 + 24
A = 18.5 no es factible porque estamos buscando numeros enteros
x = 10, entocnes 4A = 50 + 30
A = 20
al reemplazar, nos da una edad de 3(20 - 10) = 30 para Luis, y 30 + 20 = 50
