Answer:
x=5
Step-by-step explanation:
isolate the x on one side of the equal sign so move the 2 over by adding 2
4x=x+15 ( add 2 to both sides )
then move the x over
3x=15 ( subtract x from both sides )
then divide by 3
x=5
Answer: Hope it helps, have a nice day :)
x=5
Step-by-step explanation:
So you can only have x on one side, so first you move an x to the other side of the equal sign.
so, 4x-2=x+13, you can move either x, but I'm moving x instead of 4x
-x -x
Your new equation is 3x-2=13, because the x's cancel out
Then you add 2 on both sides 3x-2=13
+2 +2
___________
3x=15
then you divide by 3 on both sides
3x divided by three leaves x by itself, and 15 divided by three is 5.
3x=15
3 3
x=5
A 3 inch by 5 inch photograph is enlarged so that the longer side is 15 inches.
What is the length of the shorter side of the enlarged photograph
Answer:
the length of shorter side is 9 inches.
longer side is enlarged 3times

Which graph represents the solution set for the quadratic inequality x^2 + 2x + 1 > 0?
Answer:
The answer you selected is correct.
Step-by-step explanation:
The answer has to be greater than 0 so the bottom graph is correct.
The graph that represents the solution set for the quadratic inequality is option (C) is the correct answer.
What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal. It is used most often to compare two numbers on the number line by their size.
For the given situation,
The quadratic inequality is x^2 + 2x + 1 > 0
[tex]x^2 + 2x + 1 > 0[/tex]
⇒ [tex](x+1)(x+1) > 0[/tex]
Plot this function on the graph as shown below.
From the graph, the function extends in both positive and negative direction at x = -1.
On number line, we can denote it as x = -1 and extends up to infinity on both sides.
Hence we can conclude that the graph that represents the solution set for the quadratic inequality is option (C) is the correct answer.

A retailer sends scratch-off coupons to registered customers; 30% of the coupons will reveal a discount of 50%. Before mailing, a manager selects 10 coupons at random from the stack of printed coupons and scratches to reveal the discount.
What is the probability that none of the coupons reveal a discount of 50%?
Upper P (Upper X = k) = (StartBinomial n choose k EndBinomial) (p) Superscript k Baseline (1 minus p) Superscript n minus k
Round to 3 decimal places.
The probability that none of the coupons reveal a discount of 50% is 0.28.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Binomial distribution states that,
P = [tex]^nC_kp^k q^{n - k}[/tex]
Now,
30% of the coupons will reveal a discount of 50%.
This means,
p = 30% = 0.3
q = 70% = 0.7
Now,
Select 10 coupons:
n = 10
Now,
The probability that none of the coupons reveal a discount of 50%.
[ None means k = 0 ]
So,
P(k) = [tex]^nC_kp^k q^{n - k}[/tex]
P(0) = [tex]^{10}C_0(0.3)^0 (0.7)^{10 - 0}[/tex]
P(0) = 10 x 1 x 0.028
P(0) = 0.28
Thus,
The probability that none of the coupons reveal a discount of 50% is 0.28.

Answer:
No
Step-by-step explanation:

2 goes into 6 3 times so it would be the same as 1 going into 3 3 times.
[tex]\frac{1}{3} \frac{5}{3}[/tex]
Since 3 doesn't go into 5 at all (and by that I mean a whole number) you don't change it.
Multiplying 1/3 and 5/3, you would get 5/9.
Multiplying 2/3 and 5/6, you would get 10/18, which simplifies to 5/9.

In the figure below, m || n and p II q. Find the values of y and x.
Answer:
x= 33
y= 106
Step-by-step explanation:
4x-58=74
+58 +58
4x=132
4x/4=132/4
x=33
If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
It is known that the If two parallel lines intersect another two parallel lines then all corresponding angles will be the same.
Therefore, 74 = 4x - 58
4x = 132
x = 33.
Since 74° and the adjacent angle of y° are made by two parallel lines on the same line thus both will also same.
The adjacent angle of y = 74°
Since, adjacent angle + y = 180°
y = 180 - 74 = 106°.
Hence "If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°".

Write a linear function f with f(2)=−2 and f(1)=1.
Answer - the answer should be: -3x+4
down below is how i did it,
Step-by-step explanation:
use the formula mx+b=y
y is f(x)
m = -3
x = x
b = 4
so,
mx+b is -3x+4
A linear function is the function of a straight line.
The linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]
The given parameters are:
[tex]\mathbf{f(2) =-2}[/tex]
[tex]\mathbf{f(1) =1}[/tex]
Calculate the slope (m)
[tex]\mathbf{m = \frac{f(b) - f(a)}{b -a}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{-2-1}{2 -1}}[/tex]
[tex]\mathbf{m = \frac{-3}{1}}[/tex]
[tex]\mathbf{m = -3}[/tex]
The linear function is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
This gives
[tex]\mathbf{y = -3(x - 1) + 1}[/tex]
[tex]\mathbf{y = -3x + 3 + 1}[/tex]
[tex]\mathbf{y = -3x + 4}[/tex]
Rewrite as:
[tex]\mathbf{f(x) = -3x + 4}[/tex]
Hence, the linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]

The given equation has one solution which is the variable x = -27.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.
The equation is given in the question,
0.4(5x – 15) = 2.5(x+3)
Multiply both sides by 10
0.4(5x – 15) × 10=25(x+3) × 10
Refine
4(5x–15) =2.5(x+3)
Expand 4(5x-15): 20x-60
Expand 25(x+3): 25x+75
20x-60 = 25x+75
Add 60 to both sides
20x-60+60 = 25x+75 +60
Simplify the above equation,
20x=25x+135
Subtract 25x from both sides
20x-25x = 25x+135-25x
-5x = -135
Divide both sides by -5
-5x / -5 = -135/5
x = -27
Therefore, the given equation has one solution which is the variable x = -27.
