Which value of x makes the equation -5x-(-7-4x) =-2(3x-4 true?
Answer:
x = 1/5
Step-by-step explanation:
Step 1: Write equation
-5x - (-7 - 4x) = -2(3x - 4)
Step 2: Solve for x
Distribute: -5x + 7 + 4x = -6x + 8Combine like terms: -x + 7 = -6x + 8Add 6x to both sides: 5x + 7 = 8Subtract 7 on both sides: 5x = 1Divide by 5 on both sides: x = 1/5Step 3: Check
Plug in x to verify it's a solution.
-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)
-1 - (-7 - 4/5) = -2(3/5 - 4)
-1 - (-39/5) = -2(-17/5)
-1 + 39/5 = 34/5
34/5 = 34/5
The IQ scores for students at a certain school follow a bell-shaped distribution with mean 102 and standard deviation
10. Kyla, a student at this school, had a standardized IQ score of 1.2. What was her actual IQ score?
104
107
111
114
120
Answer:
104
Step-by-step explanation:
If the standard deviation is 10, multiply it by .2 to get 2. Add 102 and you get 104.
y=1/2(x+4)(x-2) vertex
Answer:
(-1, -4.5)Step-by-step explanation:
[tex]y=\frac12(x+4)(x-2)\quad\implies\quad x_1=-4\,,\ \ x_2=2[/tex]
vertex is (p, q) where:
[tex]p=\dfrac{x_1+x_2}2=\dfrac{-4+2}2=\dfrac{-2}2=-1\\\\q=f(p)=\frac12(-1+4)(-1-2)=\frac12(3)(-3)=-\frac92=-4.5[/tex]
So the vertex is: (-1, -4.5)
At a sale, the $39.97 original price of the shirt was marked down to $15.99. About
what percent of decrease is this?
What’s the answer??????
Answer:
720 gallons
Step-by-step explanation:
First, find how many gallons are cleaned per hour.
You can use a ratio:
36 gallons = x gallons
1/4 hour 1 hour
Cross multiply:
36 (1) = 1/4x
36 = 1/4x
(36 = 1/4x) (4/1)
144 = x
x = 144
Then, use this info to find how many gallons per 5 hours.
You can use a ratio:
144 gallons = y gallons
1 hour 5 hour
Cross multiply:
144 (5) = 1y
720 = y
y = 720
There are 720 gallons cleaned per 5 hours.
A frozen yogurt shop offers a rewards system for frequent customers. The graph below represents how much a rewards customer pays based on the number of ounces of frozen yogurt purchased.
A graph titled Customer Rewards. The horizontal axis shows ounces of yogurt purchased, numbered 2 to 22, and the vertical axis shows Total Spent (dollars) numbered 1 to 11. A line begins at 0, extends to 5 dollars spent at 10 to 12 ounces, and ends at 9 dollars spent at 20 ounces.
Which statement describes the total amount a rewards customer pays for 10 ounces and 12 ounces of yogurt?
A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.
A rewards customer pays $5 per ounce because the total amount paid is always increasing.
A rewards customer pays $20 for 10 or 12 ounces of yogurt because the total amount paid is increasing.
A rewards customer earns 5 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.
Answer:
A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.

What is the range of this quadratic function?
Answer:
(negative infinity, 4]
Step-by-step explanation:
Reminder: the range is all the possible y values the function can get by plugging in x values.
Since this is a downward opening parabola, it won't have a lower boundary, which means that the answer must be (negative infinity, 4]
We can further check that's correct by seeing that the parabola has its vertex at 4, which is written in the answer.
That means the correct answer must be (negative infinity, 4]

Find the measure of each angle. Assume the lines are parallel.
Answer:
2 = 67
3 = 113
4 = 67
5 = 113
6 = 67
7 = 113
8 = 67
Step-by-step explanation:
opposite angle have to equal 180 because if you combine them they just become the line.
since the lines are parallel, measurements will be the same for the bottom set of angles as they are the top set of angles.
How many solutions does a system of equations have when solving results in the statement 3 = 5?
A. One solution, x = 3
B. No solution
C. Infinitely many solutions
D. One solution, x = 5
Answer:
B. No solution
Step-by-step explanation:
Given that the result of the equation is 3 = 5
Therefore the results of the equation is impossible to be correct, and therefore, there are no values that can be given to the variables to make the equation true.
The characteristics of an equation with no solution is one whose result makes a statement that is false, such as given in the question, and the equations are said to be contradictory or not compatible.

Jill says 12.6¯¯¯ is less than 12.63. Explain her error.
P.S: The line is supposed to be over the 6
Answer:
Her error is 12.6¯¯¯ being more than 12.63
Step-by-step explanation:
The bar above the 6 means repeating so 12.6¯¯¯ would be 12.666 and 12.666 is more than 12.63.

What is the measure of angle 1 in degrees?
Answer:
73 degrees
Step-by-step explanation:
The interior angle equals to 180. 73+37+ m<2 = 180. That means angle 2 is 70 degrees.
m<1 and m<C and equal due to alternate interior angles. That means angle 1 is 37 degrees.
We know angles 1 and 2 equal to 37 and 73. That means the angles are equal to the interior triangle. 70+37= 107. 180-107= 73 Degrees

Stephen rolls a fair dice 300 times.
How many times would Stephen expect to
roll a two?
Answer:
50 chances to roll a 2
Step-by-step explanation:
Since Stephen is most likely rolling a 6 sided dice, divide 300 by 6 because all sides have an equal change of being rolled.
300/6 = 50
i need help with this also. (homework due tomorrow)
Answer:
Using Pyhagoras theoram,
(H)^2 = (B)^2 + (P)^2
B = 13 in
P = 5 in
[tex](h)^{2} = (13)^{2} + {(5)}^{2} \\ = > (h)^{2} = 169 + 25 \\ = > (h)^{2} = 194 \\ = > h = \sqrt{194} \\ = > h = 13.92[/tex]
Hence, the missing side is 13.92 inhes.
Answer:
13.93
Step-by-step explanation:
[tex]5^{2} + 13^{2} = c^{2}[/tex]
[tex]25 + 169 = 194 = c^{2}[/tex]
[tex]\sqrt{194} = c^{2}[/tex]
[tex]13.92838827718 = c[/tex]
then round up to 13.93
