Answer:
x = 5
Step-by-step explanation:
Step 1: Distributive property
Using this property means when you have something like the equation on the right side ( 4 ( x + 3 ) ) you multiply both the values in the parentheses by the number outside:
4 ( x + 3 )
( 4 x X ) + ( 4 x 3 )
4x + 12
8x + 2 = 2x + 4x + 12
Step 2: combine like terms
Combining like terms is when you find like terms with the same variables and such and add them together:
8x + 2 = 12 + ( 2x + 4x )
8x + 2 = 12 + 6x
Step 3:Using inverse operations
This means that you need to get a variable one one side and a constant on the other:
8x + 2 ( -2 ) = 12 ( -2 ) + 6x
8x = 10 + 6x
8x ( -6x ) = 10 + 6x ( -6x )
2x = 10
Step 4: solve for the variable
The last thing you need to do is divide both sides by the constant with the variable ( 2x ) to get x by itself:
2x ( /2 ) = 10 ( /2 )
x = 5
Answer:
x=5
Step-by-step explanation:
Step 1:Using the distributive property on the right side of the equation
8x+2=2x+4(x+3)
8x+2=2x+4x+12
Step2:Combining the like terms on the right side if the equation (Since there are no like terms on the left side) :
8x+2=6x+12
Step 3: Using the inverse operations to get the variables on the left side and the constants on the right side of the equation :
8x-6x=12-2
Step4: Using inverse operation to solve for the variable of interest which is 'x':
2x=10 (Dividing both sides by two sides by 2)
x=5

inches, what is the height of the cylinder?
Answer:
8 inches
Step-by-step explanation:
Height = Volume / Base Area = 301.44 / 37.68 = 8

15 Which line passes through the point (1.-4)? A x + y = 5 B.X + y = 5 c.xy=5 D.x-y=.5
Answer:
Step-by-step explanation:
A x + y = 5 1 + -4 = -3 Nope
B.X + y = 5 1 + -4 = -3 Nope same as A unless X is somehow not equal to x,
C. xy = 5 1(-4) = -4 Nope and does not even qualify as a line.
D. x - y = .5 1 - (-4) = 5 Nope unless you have a typo adding an unwanted decimal point
Solve for x - 5 - 3 * + 1 = - 45
Answer:
[tex]x = \frac{41}{2} [/tex]
Step-by-step explanation:
x - 5 - 3x + 1 = -45
-2x - 4 = -45
-2x = -45 + 4
-2x = -41
x = 41 ÷ 2
x = 41/2
Step-by-step explanation:
[tex]\tt{}x - 5 - 3x + 1 = - 45[/tex]
[tex]\tt{} - 2x - 4 = - 45[/tex]
[tex]\tt{}- 2x= - 45 + 4[/tex]
[tex]\tt{} - 2x = - 41[/tex]

Factor x⁴ + 3x² + 2 completely.
All factors in your answer should have integer coefficients.
Answer:
x = i, ~1.41i
Step-by-step explanation:
Assuming "integer coefficients" allows imaginary numbers:
(x^2 + 1)(x^2 + 2)
x^2 = -1 = i
x^2 = -2 = ~1.41i

Jessie made 15 sales calls yesterday. Clay made n calls. If clay made 3 times as many sales calls as jessie, choose the equation thats shows how many sales calls clay made yesterday
Answer:
n = (15)(3) = 45
Step-by-step explanation:
This problem is very simple, all we need to do is take the information we get and put it in equation form.
Jessie made 15 calls, Clay made 3 times as many as her. 15 times 3 is 45. Put in equation format it will look like:
n = (J) * (3)
n is how many calls Clay made, and J is how many calls Jessie made.
The cost of bananas, y, is directly
proportional to x, the pounds of bananas
purchased. If 2.5 lbs of bananas costs
$1.50, find the total cost of a lbs of
bananas.
The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The cost of bananas, y, is directly proportional to x, the pounds of bananas purchased. Then the relationship is given as,
y ∝ x
y = kx
Then the relationship between 'x' and 'y' will be linear. If 2.5 lbs of bananas cost $1.50. Then we have
1.50 = k (2.5)
k = 0.60
Then the equation is given as,
y = 0.60 x
Then the total cost of 9 lbs of bananas will be given as,
y = 0.60 (9)
y = 5.4 lbs
The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

the answer is 17x+20
Step-by-step explanation:
7x+10x+20
17x+20
hope it helps
mark me brainliest pls
Answer:
17x+20
Step-by-step explanation:
like terms= 7x and 10x so add= 17x
unlike term 20 it remains as it is.
so 17x+20 further cannot be simplified as both are unlike terms
given l m n find the value of x.
(9x+18) = (2x+19)
Answer:
Step-by-step explanation:
Not sure what "given l m n " means...
If you want the value of x in (9x+18) = (2x+19)
then
(9x + 18) = (2x + 19)
9x + 18 - 18 = 2x + 19 - 18
9x = 2x + 1
9x - 2x = 2x - 2x + 1
7x = 1
7x/7 = 1/7
x = 1/7
Are these functions inverses of each other?Be sure to explain how you know they are inverse or why they are not. Show all work necessary.
Answer:
Yes. f(x) and g(x) are inverses of one another
Step-by-step explanation:
[tex]f(x) = - \frac{1}{2} x - 2 \\ y = - \frac{1}{2} x - 2 \\ x = - \frac{1}{2} y - 2 \\ x + 2 = - \frac{1}{2} y \\ - 2(x + 2) = - \frac{1}{2} y \times - 2 \\ - 2x - 4 = y \\ {f }^{ - 1} (x) = - 2x - 4[/tex]
In step 1 we just copied the original function.
In step 2 we substituted y for f(x).
in step 3 we switched the variables.
in step 4 we added 2 to both sides.
in step 5 we multiply both sides by -2
In step 6 we solved for y.
In step 7 is just a fancy way of saying the inverse function f(x) = -2x - 4

Someone help!!
Answer:
A) 2
Step-by-step explanation:
The square root of 4 is 2 because 2 x 2 = 4.
The equation says x = 4, and what your trying to solve is the square root of that, not the root. The root to 4 would be 16 if it was reversed.

"keep-change-flip" is a strategy used to dividing fractions.
always change the mix fraction to a improper fraction and you slove.
I'll do the first one and the rest is basically done the same way.
for the last fraction equation I cross multiply the 4 divided into 4 gives you 1 and the 3 divided into 21 gives you 7.
