Can someone please solve this before my mom takes away my phone?
4(3+2x) + 2 = 46 , solve for x I need help I'm a bit confused
Answer:
x=4
Step-by-step explanation:
4(3+2x)+2=46
12+8x+2=46
12+8x=44
8x=32
x=4
Answer:
4
Step-by-step explanation:
You need to start with the 2x inside the parenthesis
If you put 4 in place of x you get 8
8+3=11
then because there isnt any sign between 4 and the parenthesis you multiply
4x11=44
then its easy
44+2=46
Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.
y = 3x −24y = 3x −24
y = 3x + 24
y = -3x + 24
y = -3x - 24
Step-by-step explanation:
let eqn be y = mx + b.
3y = x - 15
y = 1/3x - 5
perpendicular means product of grad = -1
hence m = -3.
sun (8, 0):
8 = -3(0) + b
b = 8
therefore, equation if the line is y = -3x + 8

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
(x, y) → (x + 5, y – 3)
(x, y) → (x + 5, y + 3)
(x, y) → (x – 3, y + 5)
(x, y) → (x + 3, y + 5)
Answer:
Omg the picture is so funny but the first one describes the translation
(x,y)> (x + 5, y - 3
Step-by-step explanation:
I hope this helped!
Answer:
Its C. (x, y) → (x – 3, y + 5)

Convert the equation from standard form to slope-intercept form.
Answer:
y=x-1
Step-by-step explanation:
The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.
First, subtract 1 from both sides
x-y-1=1-1
x-y-1=0
Then, add y to both sides
x-y-1+y=0+y
x-1=y
So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.
Answer:
y=x-1
Step-by-step explanation:
It is y=x-1 because first when we do ANYTHING first. We leave the y on the left side of the equation, since the slope y=mx+b has the y always on the left side. So we subtract x from both sides and we get -y=-x+1. We are NOT DONE yet, so after this, we divide both sides by -1. Why? This is because you cannot have a negative y. Dividing both sides by -1 you finally get y=x-1. If this is trouble some to read, I will also put how to solve the problem down below. :)
Let's solve for y.
x−y=1
Step 1: Add -x to both sides.
x−y=1+−x
−x
−y=−x+1
Step 2: Divide both sides by -1.
−y/ −1 = −x+1 /−1
y=x−1
Answer:
y=x−1

i-solve the fraction 315+79 (show all steps)
Answer:
Step-by-step explanation:
step 1 Address input parameters & values.
Input parameters & values:
The fraction number = 315/79
step 2 Write it as a decimal
315/79 = 3.9873
3.9873 is the decimal representation for 315/79
For Percentage Conversion :
step 1 To represent 3.9873 in percentage, write 3.9873 as a fraction
Fraction = 3.9873/1
step 2 multiply 100 to both numerator & denominator
(3.9873 x 100)/(1 x 100) = 398.73/100
398.73% is the percentage representation for 315/79

Step-by-step explanation:
3x + 4 = 8x – 11 does anyone know how to do this
Answer:
x = 3
Step-by-step explanation:
Subtract 8x from both sides.
3x+4−8x=8x−11−8x
−5x+4=−11
Subtract 4 from both sides.
−5x+4−4=−11−4
−5x=−15
Divide both sides by -5.
−5x
−5
=
−15

Grades 1 through 6 at Eastwood Elementary School raised $5,492 towards repairs for the gymnasium floor.
How much did each grade raise if they each collected about the same amount of money? Choose the best estimate. this was not answered correctly the first time...
Answer choices:
A. About $1,100
B. About $900
C. About $550
D. About $500
Answer:
b
Step-by-step explanation:
If you divide 5,492 by 6 on a calculator you get 915.333333333 . So if you estimated it each grade raised about $900
these two polygons are similar
Answer:
y=5
Step-by-step explanation:
you can see yellow on the top left it has a 6 and on the red it has a 2.So 6/3=2and you can do that with to bottom 15/3=5

Find the difference 10 - ( – 25 )
Answer:
35
Step-by-step explanation:
In such cases where there are two minuses, you join them and turn it into a plus sign. So therefore...
= 10 - ( -25 )
= 10 + 25
= 35

If AD = 8 and AC = 2y - 10 , find the value of y. Then find AC and DC.
Answer:
y=13
Step-by-step explanation:
AD is identical to DC so if half of AC is AD which is 8, AC must be 16
2y - 10 = 16
2y = 26
y = 13

Thomas and Sydney have a combined age of 57. Thomas is 13 years older than triple Sydney’s age. How old is Thomas? You must create a system of equations and use substitution to solve.
57-13=44. If Sydney is 11, then Thomas is 46. 11x3=33, and 33+13=46. To check our answer, we will add 46+11. 46+11=57.
