[tex]\boxed{x_1 = \frac{2}{3} ~~or~~x_2 = 1}[/tex]
.
Step-by-step explanation:
[tex](3x - 2)(5x - 4) = (3x - 2)^2[/tex]
[tex]15x^2 - 12x - 10x + 8 = 9x^2 - 12x + 4[/tex]
[tex]15x^2 - 22x + 8 - 9x^2 + 12x - 4 = 0[/tex]
[tex]6x^2 - 10x + 4 = 0[/tex] → divide both segment by 2
[tex]3x^2 - 5x + 2 = 0[/tex]
[tex](3x - 2)(x - 1) = 0[/tex]
[tex]3x - 2 = 0[/tex]
[tex]3x = 2[/tex]
[tex]x = \frac{2}{3}[/tex]

If c=g-4f, find trinomial that represents C when F=2x^2-5 and G=5x^2+x-3
Answer:
c = -3x² + x + 17
Step-by-step explanation:
c = g - 4f
f = 2x² - 5
g = 5x² + x - 3
c = (5x² + x - 3) - 4(2x² - 5)
c = 5x² + x - 3 - 8x² + 20
c = -3x² + x + 17

What is 116.52 plus 8% as tax
Answer:
125.84
Step-by-step explanation:
116.52(0.08)=9.32
116.52+9.32=125.84
Answer:
The total is $125.84.
Step-by-step explanation:
The total is equal to the original value (100%) + the tax amount (8%) which equals 108%. To multiply it, we move the decimal two to the left to get our figure (1.08) then multiply that times 116.52. So, 116.52x1.08=125.8416; for dollars I rounded to the nearest cent: $125.84.

20 pointssssss............
Answer:
The answer you have clicked is correct
Step-by-step explanation:
To get x alone you need to get rid of the 4 so you subtract it from both sides
so then you have
x + 4 - 4 = 24 - 4
the fours on the left cancel out
x = 24 - 4
subtract
x = 20
and there's the answer and steps :)
how do u add really big fractions
Answer:
It depends on your situation
Step-by-step explanation:
If you have a mixed fraction, for example: 5 23/3000 + 101 777/3000 you would have to make them irrational numbers and add them. Like so: 3000x5 = 15000. 15000+23 = 15023. 15023/3000. Same process but this time you get 303777/3000. You then add the numerators (top numbers) and you'll get the sum over 3000.
For regular fractions you simply add the numerators. If your denominators are not the same, you need to find a common term that both can fit into. If the denominators are not the same, no matter the size of the fraction, you cannot add it.

Ade is baking mini-loaves of bread. How many mini-loaves could he make with 10 cups of flour?
Answer: 25
Step-by-step explanation:
Since Ade uses 2 cups of flours for 5 mini loaves, it simply means that 1 cup of flour will be used for:
= 5/2 = 2.5 mini loaves
Therefore, the number of mini-loaves that he could make with 10 cups of flour would be:
= 10 × 2.5
= 25 mini loaves

If it takes 9 3/4 yards of material to make curtains for 3 windows, how much material is needed?
Answer:
3.25 yards of materials will be needed for 1 window
Answer:
3 1/4 (Verified) ✅Step-by-step explanation:
This is a rate problem, so we will write rate as a proportion and write the desired rate with x for the unknown value we need to find.
9.75/3 = x/1
Cross-mulitply
3x = 9.75
Divide by 3
x = 3.25 or 3 1/4
Another great thing with proportions is that we can check them to ensure we got the correct answer. All we do is substitute our determined value in for x
9.75/3 = 3.25/1
9.75 = 9.75 ✅
The answer of x = 3 1/4 is correct.

A little girl standing next to a telephone pole at 10 AM. The little girl is 4'6" tall and the telephone pole is 40 feet high. If the telephone pole cast 8 32 foot shadow, how long is a little girl shadow?
Answer:
The shadow of the pole is 1.2 feet long
Step-by-step explanation:
A little girl standing next to a telephone pole at 10 AM.
From the above question
Height of the girl = 4'6" tall = 4 feet and 6 inches tall
We convert to feet
= 12 inches = 1 foot
6 inches = x
Cross Multiply
12 × x = 6 × 1
x = 6/12 = 1/2 = 0.5 feet
Hence, the total height of the girl =
4 feet + 0.5 feet = 4.5 feet
The height of the telephone pole = 40 feet high.
The shadow of the telephone pole
= 8' 32 foot shadow
= 8 feet, 32 inches
We convert the inches to feet
12 inches = 1 foot
32 inches = x
Cross Multiply
12 × x = 32 × 1
x = 32/12 = 8/3 = 2.67 feet
Total length of the pole = 8 feet+ 2.67 feet = 10.67 feet
how long is a little girl shadow?
This is calculated using proportion
Shadow/Height
Shadow of the girl = x
Hence:
Shadow of the girl/Height of the girl = Shadow of the pole/Height of the pole
x/4.5 feet = 10.67 feet/40 feet
Cross Multiply
40 × x= 4.5 × 10.67
x = 4.5 × 10.67/40
x = 1.200375 feet
Approximately = 1.2 feet
Hence, the shadow of the pole is 1.2 feet long

-4x -2y = -12
4x + 8y = -24
x= 6 and y= -6
Step-by-step explanation:
Answer:
x = 6, y = -6
Step-by-step explanation:
After adding the equations together, the 4x and -4x cancel each other out. This makes our new equation:
6y = -36
Divide both sides by 6
y = -6
Plug -6 into y in one of the equations
4x + 8y = -24 =
4x + 8(-6) = -24 =
4x - 48 = -24
Add 48 to both sides
4x = 24
Divide both sides by 4
x = 6

Find the slope of the line.
Answer:
C
Step-by-step explanation:
Well You can tell right away its a positive line since its rising from left to right so the answer has to be positive
If the slope were to be 4 the line would be a Little more titleted becuasea slope of 4 is going up 4 and going tot he right 1.
ANd you can’t heck from any given point and just try all the positivw possibilties.
Or you can just use rise over run, start form a point, rise which means go up until you reach the second layer of the line and just run (go To The right) until you hit a point.

Which of the following visual representation correctly displays a relationship between sets of real numbers
PLEASE HELP
Answer:
d. J
Step-by-step explanation:
Real numbers are the vast set of numbers that broadly categorize into Rational and Irrationals (and also the Transcendentals, which are irrational too). Every rational number and every irrational number are characteristicly different from each other. Following this order, all rationals and irrationals are real numbers. This order is best represented in the Figure J.
Answer:
J
Step-by-step explanation:
Real numbers are classified into two types,
(i) Rational numbers - A number which can be expressed as fraction, ratio or percentage is called as rational number
(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.
Since there are no common numbers in rational and irrational, they cannot be expressed as "G" option.
Real numbers are formed by the union of rational and irrational numbers.
Write the equation of the line passing through the points (2,-5) (3,-1)
Answer:
they give you two points... so use the point slope formula with one on the points
y - y1 = m ( x - x1)
Step-by-step explanation:
find the slope m
m = y2 -y1 / x2-x1
from the given.. x1=2 and y1 = -5
x2 = 3 and y2 = -1 then,
m = -1 -( -5) / 3 - 2
m = 4/1
m = 4
now plug in to the point slope formula either of the points... I'll use the 1st point
y - 2 = 4(x -(-5))
y -2 = 4(x +5)
y -2 = 4x +20
y = 4x +22
