Answer:
missing value is 5
Step-by-step explanation:
Change them to all have the same denominator
8/12 + 3x/12 = 23/12
multiply all by 12
8 + 3x = 23
subtract 8
3x = 15
divide by 3
x = 5
y = 2x²- 5x + 2
determine the x value for the vertex and whether this value is a maximum or a minimum
a. maximum at x = -1.25
b. maximum at x = 1.25
c. minimum at x = -1.25
d. minimum at x = 1.25
Answer: D
Explanation:
Use the vertex formula, -b/2a. Because the quadratic formula is ax^2+bx+c, -b would be 5 in this case and a would be 2 in this case. Plug the numbers in and you get 5/4. The AOS or vertex would be 5/4 or 1.25. Because the a-value is a positive in this equation, the parabola would have a minimum.
Does anyone know the answer to this question. I already tried A and C.
I think the answer would have to be D. If the diameter, which is the distance from one point on the circle through the center to another point on the circle, is halved then the amount of concrete that will be needed will be multiplied by 4. I think that's right I am so sorry in advance if that was incorrect. Have a beautiful rest of your day. Stay safe. C O V I D - 1 9 IS REAL THIS COULD MEAN YOUR LIFE!!!
Expand and simplify
(3x + 2)(x - 1)
Can exponents be integers
Answer:
NO
Step-by-step explanation:
Exponents are expressed as numbers or variables in superscript above a base number. When the exponent is equal to or greater than 2, it directs how many times the base number is to be multiplied. The numbers 1 and 0 are special exponents, and negative integers as exponents stand for reciprocal values.
Answer:
It matters of what the whole number in front is.
Step-by-step explanation:
For example: 6 to the power of 2 = 36
if the first number is a decimal: 1.6 to the power of 2.56
Its NOT an exponent if the starting number is a decimal usually.
If DH = (4x + 10) in. and HI = (2x − 4) in., then x =_______ , HI =_______ , and ID = _________
Answer:
x = ∞ infinite solutions or 0
HI = infinite solutions
ID = infinite solutions.
Step-by-step explanation:
Oh okay I got this now!
ID + HI = DH
ID + 2x - 4 = 4x + 10 (subtract 2x on both sides)
ID - 4 = 2x + 10 (add 4 on both sides)
ID = 2x + 14
So now ID + HI = DH
2x + 14 + 2x - 4 = 4x + 10 (simplify)
4x + 10 = 4x + 10 (subtract 10 on both sides)
4x = 4x (minus 4x on both sides)
0 = 0
I would plug in 0 as x.
Hope this helps!

What is the first step in solving this expression? 28 - 11 + 6 ● 3 + 5
Thanks,
Answer:
First Step of solving this expression: Multiply
Answer for the expression: 40
Step-by-step explanation:
To find the first step you need to follow the order of operation
Parenthesis
Exponents
Multiplication and Division
Addition and Subtraction
Since there are not Parenthesis or Exponents then you may skip that step but there is a multiplication sign so the first step is Multiplication
To solve multiply 6 and 3
Which is 18
Now the expression looks like this:
28-11+18+5
Now simplify from left to right:
28-11=17
17+18=35
35+5=40
Hope this helps!
Answer: Multiply 6*3, then add 18+5, then subtract 28-11, then add them:

Rachel signed up for a frequent-flier program. She receives 4,300 frequent-flier miles for her first round trip and 1,900 frequent-flier miles for each additional round-trip. How many frequent-flier miles will she have after 5 round-trips?
Answer: 13800 frequent-flier miles
Step-by-step explanation:
From the question, we are informed that Rachael receives 4,300 frequent-flier miles for her first round trip and 1,900 frequent-flier miles for each additional round-trip.
The number of frequent-flier miles she will she have after 5 round-trips will be:
= 4300 + 1900(5)
= 4300 + 9500
= 13800 frequent-flier miles

How many miles can he run in 230 minutes? (solve and explain the steps)
Answer:
Joe will run 22.08 miles in 230 minutes.
Step-by-step explanation:
Given that Joe can run 12 miles in 125 minutes.so Joe running the miles in 1 minute is = 12/125 = 0.096 miles
unit rate = 0.096 miles/per minuteAs Joe runs 0.096 miles in one minute.
Thus, in 230 minutes, Joe will run = 0.096 × 230 = 22.08 miles
Therefore, Joe will run 22.08 miles in 230 minutes.
