For which type of triangle below would a circumcircle whose diameter coincides with one
side of the triangle?
Answer:
right triangle
Step-by-step explanation:
A circumcircle of a polygon is a circle that passes through all the vertices of the polygon.
If the diameter of the circle is one side of the triangle, then the triangle is in the semicircle.
The angle at the circumference in a semicircle is a right angle.
Therefore, the answer is right triangle
3x+12y=-8 in slope intercept form
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!

y= -2x+4
y= 6x-20
Answer:
x = 3
y = -2
Step-by-step explanation:
Substitute -2x+4 for y:
-2x+4=6x-20
Subtract 6x from both sides
-8x+4=-20
Subtract 4 from both sides
-8x=-24
Divide both sides by -8

The table that represents the relationship between the number of meals the caterer prepares and the amount of money they charge is:
2 $50
4 $100
6 $150

What is the cost of one meal?In order to determine the correct answer, the average cost of the meal has to be determined.
Average cost = $250 / 10 = $25
Cost of 2 meals = $25 x 2 = $50 Cost of 4 meals = $25 x 4 = $100Cost of 6 meals = $25 x 6 = $150Cost of 8 meals = $25 x 8 = $200if you dig a hole 12ft deep and 6ft wide, how much dirt is in the hole?

A scientist had 3/4 L of solution use 1/6 of solution for an experiment how much solution did the scientist use for the experimen
Answer:
1/8 L
Step-by-step explanation:
In this context, "of" means "times."
1/6 of (3/4 L) = (1/6) × (3/4 L) = 3/24 L = 1/8 L
The scientist used 1/8 L of solution for the experiment.

Answer:
Their y-intercepts are equal
Step-by-step explanation:
The y-intercept is the y-value where the function crosses the y-axis. In this problem, functions are presented in 2 ways: algebraically and in a table.
1) Fortunately, the algebraic equation is written in slope-intercept form; this means that intercept is easy to find. The slope-intercept form is y=mx+b, where b is the y-intercept. In function 1, the b value is 10.
2) Another way to describe the y-intercept is the y-value when x=0. So, the y-intercept on a table is wherever the x-value is 0. In this case, the first row represents when x=0. The table says that when x=0, y=10. This means that the y-intercept for function 2 is 10.
Since the y-intercept for both of the functions is 10, it can be said that the 2 functions have equivalent y-intercepts.

Answer:
x = 35°
Step-by-step explanation:
The three angles in a triangle add up to 180°.
The little square in the corner of one angle means that is a right angle and is 90°.
90° + 55° + x = 180°
145° + x = 180°
Subtract 145° from both sides.
x = 180° - 145°
x = 35°

Credit cards are safer than cash, C. If a merchant does not hold up their end of an agreement, you can call the credit company and dispute the charges.
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.
Now, Credit cards are more safer than cash because A credit card requires a signature, so it is impossible for anyone other than you to use them.
But, A statement more convenient than this is,
If a merchant does not hold up their end of an agreement, you can call the credit company and dispute the charges.

Which function has a domain of x greater-than-or-equal-to 5and a range of y less-than-or-equal-to 3?.
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
