5x + 25 + x + 5 = 90
6x + 30 = 90
6x = 90 - 30
6x = 60
x = 10
Solution:
We can see that the 90° angle is divided into two angles. Thus, the sum of two angles must equal 90°.
=> 90 = 5x + 25 + x + 5Combine like terms:
=> 90 = x(5 + 1) + 5(5 + 1)=> 90 = x(6) + 5(6)=> 90 = 6x + 30Subtract 30 both sides:
=> 90 - 30 = 6x + 30 - 30=> 60 = 6xDivide 6 both sides:
=> 60 = 6x=> x = 60/6 = 10The value of x is 10.

Which function has a domain of x greater-than-or-equal-to 5and a range of y less-than-or-equal-to 3?.
Answers
Function's domain is the set of values on which it is defined. One such function having domain x≥ 5 and range y ≤ 3 is: [tex]y = 3 - \sqrt{x-5}[/tex]
What is domain and range of a function?Domain is the set of values for which the given function is defined.Range is the set of all values which the given function can output.There can be actually infinite functions having same domain and range.
We need to find one function whose domain is x≥ 5 and range is y ≤ 3
Let the function be [tex]y = f(x)[/tex]
For keeping the function not defined for values of x < 5, we need to make such condition such that for values x < 5, the values of the function becomes undefined.
We can use some trick which keeps one sided interval undefined. One such function is the square root function which needs the input to be non-negative,
If we input x-5 to the square root function, then x can't go below 5, as square root of negative values is not defined(if not using complex numbers).
Thus, [tex]\sqrt{x-5}[/tex] is one part of f(x).
Next, we need the output to be limited by 3.
Since the quantity [tex]\sqrt{x-5}[/tex] is never negative, so 3 - [tex]\sqrt{x-5}[/tex] is never going to be bigger than 3.
Thus, [tex]y = 3 - \sqrt{x-5}[/tex] is one such needed function, having domain x≥ 5 and range y ≤ 3

Substitute -2x+4 for y:

3x+12y=-8 in slope intercept form
Answers
y= -1/4x - 2/3
Step-by-step explanation:
You subtract the 3x on both sides. Then you would get 12y=-3x-8. From there, you would divide both sides by 12. Your finally answer would be above. Hope this helps
Answer:
[tex]y=-\frac{1}{4}x - \frac{2}{3}[/tex]
Step-by-step explanation:
Hi there!
We are given the equation 3x + 12y = -8 and we want to convert it into slope-intercept form
The equation is currently in standard form, which is ax+by=c, where a, b, and c are free integer coefficients
Slope-intercept form is y=mx+b, where m is the slope and b is the y intercept
Notice that in standard form, the terms containing x and y are both on the same side, but in slope-intercept form, the expression is set equal to y (x is on the other side)
So first, we'll need to subtract 3x from both sides to remove it from the left side.
3x + 12y = -8
-3x -3x
_______________
12y=-3x-8
Now divide both sides by 12, since we want to isolate y by itself (it's a bit like solving the equation for y)
12y=-3x-8
÷12 ÷12
___________
y=-3/12x -8/12
We can simplify the fractions to get:
[tex]y=-\frac{1}{4}x - \frac{2}{3}[/tex]
This is our final answer.
Hope this helps!

What is a credit card?A credit card is a small, rectangular piece of plastic or metal that is issued by a bank or other financial institution and enables its holder to borrow money to pay for products and services at businesses that accept credit cards.
Credit cards impose the need that cardholders repay the borrowed funds, plus any applicable interest and any other agreed-upon charges, in full or over time, either by the billing date or at a later date.
