8x + 5x what is it simplify
Answer:
13x
Step-by-step explanation:
you would just add the 2 numbers together and then keep the variable. if you know the variable (if there’s a sheet to go off of) then multiply and add but otherwise it’s just 8 + 5 then add an x. 13x
=====================================================
Explanation:
x is a placeholder for a number. Think of it like a box holding a number. Conveniently, the letter 'x' is in the word 'box', so its naturally fitting to use x here.
Writing 8x could represent the idea of us having 8 boxes that are identical. Adding on 5x means we add on 5 more boxes. This leads to 8+5 = 13 boxes in total.
This is one way to see how 8x+5x = 13x
Another way is to write it like this: 8x+5x = (8+5)x = (13)x = 13x. I used the distributive property here.
Combining these terms is possible because 8x and 5x are like terms. They have the same variable and same exponent. We're adding two of the same type of object together.

Answer:
35.228
Step-by-step explanation:
Answer:
b=21
Step-by-step explanation:
For this problem we need to use Pythagorean theorem (a^2+b^2=c^2):
20^2+b^2=29^2
Simplify the squares:
400+b^2=841
Subtract 400 from both sides:
b^2=441
Take the square root of both sides:
b=21

What is 3/4 x 6 , simplified .
Answer:
9/2
Step-by-step explanation:
3/4 x 6 can be thought of as multiplying 3/4 x 6/1
When multiplying fractions, multiply the numerator (top number) with the numerator, and the denominator with the denominator.
3/4 x 6/1 = (3x6)/(4x1)
3/4 x 6/1 = (18)/(4)
3/4 x 6/1 = 9/2

What is the slope of the line that passes through the points
(

,
−
2
)
(4,−2) and
(
24
,
−
17
)
?
(24,−17)? Write your answer in simplest form.
Answer:
-3/4Step-by-step explanation:
Given the coordinates (4, -2) and (24, -17), we are to find the slope of the line passing through the points
Slope = y2-y1/x2-x1
Slope = -17-(-2)/24-4
Slope = -17+2/20
Slope = -15/20
Slope = -3/4
Hence the required slope is -3/4

5 2/5 divided by 9/10
Answer:
Step-by-step explanation:
5 2/5 = [(5*5)]+2 / 5 = (25+2) / 5 = 27/5
(27/5)/(9/10) = 27/5 * 10/9
cross cancel 27 becomes 3 and 9 becomes 1, 5 becomes 1 and 10 becomes 2
= 3/1 * 2/1 = 6/1 = 6
a quadratic function that fits the points (0,5) (2,3) (4,9)
Answer:
Step-by-step explanation:
y=ax^2+bx+c we are given point (0,5) so if x=0, y=c, so c=5. We have two other points
(2,3)(4,9) which gives us
4a+2b+5=3 and 16a+4b+5=9
Subtracting twice the first from the second
16a+4b+5-8a-4b-10=9-6
8a-5=3
8a=8, so a=1, so using 4a+2b+5=3 we get
4(1)+2b+5=3
2b+9=3
2b=-6
b=-3 so our quadratic is
y=x^2-3x+5

Mary needs to buy 4 concert tickets and one parking pass. If parking is $12, and she can spend at most $80, what ticket prices can she afford? (set up an inequality, do not solve)
Answer:
4t + 12 [tex]\leq[/tex] 80
Step-by-step explanation:
Set up an inequality where t is the cost of one ticket
Since her budget is $80, a less than or equal sign needs to be used.
4t will represent the total cost of the tickets, since she needs to buy 4. Add 12 to this to represent the parking cost:
4t + 12 [tex]\leq[/tex] 80 is the inequality.

b= 16 mm
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2= c^2, so-
12^2 +b^2= 20^2
144+b^2=400
b^2=400-144
b^2= 256
b= 16
Answer:
16 mm
Step-by-step explanation:
A²+B²=C²
12²+x²=20²
144+x²=400
x²=400-144
x²=256
√x = √256
x = 16

Given that f(x) = x + 3/2
a) Find f(2)
b) Find f^-1(x)
c) Find f^-1(12)
Step-by-step explanation:
f(x) = x + 3/ 2
For a
f(2) = 2 + 3 / 2
= ( 4 + 3 ) /2
= 7/2
For b
f(x) = x + 3/2
f^-1(x) = ?
Let y = f(x)
y = x + 3/2
Interchanging the roles of x and y we get,
x = y + 3 / 2
y = x - 3 / 2
Therefore f^-1(x) = x - 3 / 2
For c)
f ^ -1(12) = 12 - 3 / 2
= (24 - 3) / 2
= 21 / 2

Evaluate the following expression: 8x - 6 - 7y + 3 use x=3 and y=6
Answer:
-27
Step-by-step explanation:
8x - 6 - 7y + 3
X = 3 Y = 6
8(3) - 6 - 7(6) + 3
8 x 3 = 24
7 x 6 = 42
24 - 6 - (42 + 3)
(24 - 6) - 45
18 - 45 = -27
