Step-by-step explanation:
let the 1st number be x
and,
2nd number = 2x
3rd number = 2x + 6
their sum = 66
so, after inserting the values we got
→ x + 2x + 2x + 6 = 66
→ 5x + 6 = 66
→ 5x = 66 - 6 = 60
→ x = 60/5 = 12
→ x = 12
therefore,
1st number = x = 12
2nd number = 2x = 12 × 2 = 24
3rd number = 2x + 6 = 24 + 6 = 30

Answer:
Domain is 3 <x>_-2
Range is 6 <x>_-3 (the lines are supposed to be under the >. it means equal to)
Step-by-step explanation:
First look on the x-axis, is goes from 3 to -2. now look at the colored in dot. that means more than or equal to. So the sign of -2 is x >_ -2. put the 3 on the other side. It stops at three so the sign is > 3. so 3<x>_ -2
Do the same with the y-axis except look up and down instead of left and right. so the numbers are 6 and -3. Use the same method above. this is set builder notation.

why is math so hard like 23/24 × 34/56 in simplest form I just whish math was never a thing
Hey there! :)
[tex]\frac{23}{24} *\frac{34}{56}[/tex]
Let's reduce our fraction:
We can divide 24 and 34 by 2:
[tex]\frac{23}{12} *\frac{17}{56}[/tex]
Now it's a little easier. All we have to do is multiply 23 times 17 and 12 times 56.

Which one of the following values of k makes the trinomial 9x^2 + kx + 64 a perfect square
a 24
b 48
c 16
d 42
Answer:
it is C 16
Step-by-step explanation:
x² - kx + 64
Since we are looking for a perfect square, then we need to take the square root of 64 to find the factors: √64 = 8
So, the factors are: (x - 8)(x - 8)
Foil (or distribute) to get: x² - 16x + 64 The k-value is 16
Which answer is an equation in point-slope form for the given point and slope?
Point: (5, 9); Slope: 2
y-5= 2 (2 +9)
y-9=2(x+5)
y+9= 2(2-5)
y-9=2(x – 5)
Answer: y-9=2(x-5)
Step-by-step explanation: The point (5,9) satisfies the equation:
y-9=2(x-5) for (5,9)?
9-9=2(5-5) ?
0 = 0 YES
Slope of 2? Rewrite:
y-9=2(x-5)
y = 2(x-5)+9
The slope is 2 YES

-7 + 8x2 - 4x
Answer: 8x^2 -4x -7
Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7
so it would be 8x^2 -4x -7
The polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.
To write the polynomial -7 + 8x² - 4x in descending order, we arrange the terms from highest degree to lowest degree.
Here's how to do it step by step:
Step 1: Identify the degree of each term:
The term -7 has a degree of 0 (since it is a constant).
The term 8x² has a degree of 2 (since it has a variable raised to the power of 2).
The term -4x has a degree of 1 (since it has a variable raised to the power of 1).
Step 2: Arrange the terms in descending order based on their degrees:
Start with the term with the highest degree and proceed in decreasing order. In this case, we have only three terms, so we start with the highest degree term:
8x² (degree 2)
Next, we consider the next highest degree term:
-4x (degree 1)
Finally, we have the constant term:
-7 (degree 0)
Step 3: Write the polynomial in descending order:
Putting the terms together in descending order, we have:
8x² - 4x - 7
So, the polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.

x=
solve, x − 5y = 6 for x.
Answer:
Step-by-step explanation:
To solve for x you have to move the -5y to the other side of the equals sign. Since the opposite of subtracting is adding, we will add 5y to both sides to get
x = 5y + 6
