What’s the
What triangle can be formed with angle measures of 32,126,and 32
Answer:
Yes.
Step-by-step explanation:
32 + 32 + 126 = 180
This means that a triangle can be formed, as the angles add up to 180°.

Write a real life scenario that could model the following relationship:
y=20x+60
Make sure to include what x and y represent in your description.
Answer:
You work for x hours and earn $20 for each hour. You get paid $60 before you come in each day. What is y when you work for x hours?
Step-by-step explanation:
x is the independent variable and can vary. You have to add the $60 in there, too. Adding them together gets you to y = 20x + 60 and this real life scenario works.
I’m having trouble with this, at first I got x=6 but it isn’t right, can anyone help?
Answer:
x=12

they are equal to each other, so you set 10x-48 equal to 6x and solve.
reflect triangle abc over the line x= -1 and then translate (x+2,y-5) determine the coordinates of B'
Answer:
below
Step-by-step explanation:
You didn't show the triangle, but we suppose the coordinate of B is (x,y)
when it reflect over the line x=-1, (x , y) - > (- (x - (-1)) , y) ==> (- (x+1) , y)
then translate (x+2,y-5) : (-(x+1) , y) -> - (-(x+1)+2 , y-5) ==> (-x+1 , y-5)
such as (5,3) -> (-6,3) -> (-4 , -2)
What is negative 9 divided by 2?
Answer:
-[tex]\frac{9}{2}[/tex] = -4.5
Step-by-step explanation:
-9 ÷ 2
Fraction [tex]\frac{-9}{2}[/tex] can be written as [tex]-\frac{9}{2}[/tex] by extracting the negative sign.
[tex]-\frac{9}{2}[/tex]
Factor:
[tex]\frac{(-1)x3^{2} }{2}[/tex] = -4.5
Steven deposits $200 in a savings account, and decides to increase the amount by $5 every month. Identify the function that describes the arithmetic sequence, and the amount he should deposit after 8 months.
possible answer: D = 8n + 200; $240
possible answer: D = −5n + 200; $160
possible answer: D = 5n + 200; $240
possible answer: D = −8n + 200; $160
The required equation is D = 5n + 200 and the amount deposited after 8 months is $240
Given the amount that steven deposited every month as $200
Let n be the number of months
If he decides to increase the amount by $5 every month, then the amount added after n months will be $5nThe function that describes the arithmetic sequence will be expressed as sum of the amount deposited and increment:D = 200 + 5n = 5n + 200
In order to get the amount deposited after 8 months, we will replace n by 8 to have:
D = 200 + 5(n)
D = 200 + 5(8)
D = 200 + 40
D = 240
Hence the required equation is D = 5n + 200 and the amount deposited after 8 months is $240

5 ( c+ 2) = -20
12a + 5 - 8a = -1
m - 3 - 6m = -27
please solve
c = -6
a = -3/2
m = -24/5
Step-by-step explanation:
#15(c + 2) = -20
5c + 10 = -20
5c = -20 - 10
5c = -30
c = -6
#212a + 5 - 8a = -1
4a + 5 = -1
4a = -1 - 5
4a = -6
a = (-6)/4
a = -3/2
#3m - 3 - 6m = -27
-5m - 3 = -27 → (times -1)
5m + 3 = 27
5m = 27 - 3
5m = 24
m = 24/5

What number makes the expression equivalent?
what do you have to do
Alegebra. Identify the vertex and axis of symmetry of each. Please answer and e0lain how and why you got your answers.
There is no information displayed.
Here is how to do it.
How to calculate axis of symmetry:
Plug your numbers into the axis of symmetry formula. To calculate the axis of symmetry for a 2nd order polynomial in the form ax 2 + bx +c (a parabola), use the basic formula x = -b / 2a. In the example above, a = 2 b = 3, and c = -1. Insert these values into your formula, and you will get:
How to calculate vertex:
The vertex form of a quadratic is given by
y = a(x – h)2 + k, where (h, k) is the vertex.
The "a" in the vertex form is the same "a" as
in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down. Think of it this way: A positive "a" draws a smiley, and a negative "a" draws a frowny. (Yes, it's a silly picture to have in your head, but it makes is very easy to remember how the leading coefficient works.)
In the vertex form of the quadratic, the fact that (h, k) is the vertex makes sense if you think about it for a minute, and it's because the quantity "x – h" is squared, so its value is always zero or greater; being squared, it can never be negative.
Suppose that "a" is positive, so a(x – h)2 is zero or positive and, whatever x-value you choose, you're always taking k and adding a(x – h)2 to it. That is, the smallest value y can be is just k; otherwise y will equal k plus something positive. When does y equal only k? When x – h, the squared part, is zero; in other words, when x = h. So the lowest value that y can have, y = k, will only happen if x = h. And the lowest point on a positive quadratic is of course the vertex.
If, on the other hand, you suppose that "a" is negative, the exact same reasoning holds, except that you're always taking k and subtracting the squared part from it, so the highest value y can achieve is y = k at x = h. And the highest point on a negative quadratic is of course the vertex.
