Step-by-step explanation:
1. You can remember the name by just looking at their positions- they alternate and they're on the exterior
2. They are supplementary meaning they add to 180°, set the angle measures up to 180 and solve for x!
76 + 2x = 180
2x = 104
x = 52
3. Equilateral trinagles have these qualities
4. Those hashes on the sides of the triangles signify those sides are the same length- that means the angles opposite of those sides share the same angle measure. If you know two angles are 35, and the last angle is 2x, you can set up an equation:
35 + 35+ 2x = 180
70 + 2x = 180
2x = 110
x = 55
5. That square means a right angle which equals 90°, like question 4, you set up an equation!
90 + 5x + 5x = 180
90 + 10x = 180
10x = 90
x = 9
6. Set up a proportion.
12 : 30 // 12(x) = 30, x = 2.5
8 : y // 8(2.5) = y, y = 20

About 16 weeks ago, there were 59 mold spores found in a garden. After a few weeks of observation, it is determined that the number of mold spores in the garden is tripling every 8 weeks.
The number of mold spores, M, at any given time in the garden is equal to the product of the initial amount of spores, I, and 3 to the power of n, where n is the number of times the amount of mold spores has tripled.
How many mold spores are in the garden today?

y=−2x+4 missing value ( - , -2)
30 points
Answers
Answer: Y=4
Step-by-step explanation:
Answer:
The missing value is 3.
Step-by-step explanation:
I plugged in -2 as y.
-2 = -2x+4
-2 -4 = -2x -4
-6 = -2x
-6/-2 = -2x/-2
3 = x
So the point is (3, -2)
The sum of 6.7 and a number is negative. What is a possible value for that number? Explain.
Answers
Answer:
The number must be greater than 6.7. Thus, the sum will be negative.
For example, the number could be 7.
6.7 - 7 = -0.3
The number can be in the range - x ∈ (- ∞ , - 6.7)
We have - the sum of 6.7 and a number is negative.
We have to determine the possible value of that number.
For what range of values of x, the given function is equals to a negative value -y = f(x) = 2x + 10For f(x) to be negative -
f(x) < 0
2x + 10 < 0
2x < - 10
x < - 5
x ∈ (- ∞ , - 5)
According to the question, we have - the sum of 6.7 and a number is negative.
Now -
6.7 + x < 0
x < 6.7
x ∈ (- ∞ , - 6.7)
Hence, the number can be in the range - x ∈ (- ∞ , - 6.7).

Answer:
First distribute (8x + 3) into (2^2+ 8x +9)
16x^3 + 64x^2 + 72x + 6x^2 + 24x +27
Then we'll order the pairs from highest to lowest degree
16x^3 + 64x^2 + 6x^2 + 72x + 24x + 27
Then we'll add up the like terms
16x^3 + 70x^2 + 96x + 27

Answers
Answer:
∠p= 15° , ∠q = 108° , ∠r = 57° Is the Answer
Step-by-step explanation:
, (x -12)° + (5x-27)° + (2x + 3)° = 180°
or, 8x° -36° = 180°
Or x =
So, x = 27°
∴ ∠P = 27° -12° = 15°
∠q = (5 × 27)° -27° = 108°
∠r = (2 × 27)° + 3° = 57°

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [
Answers
Answer:
y = 4x+3
Step-by-step explanation:
The equation in point slope form is expressed as y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
If a line is parallel to y = 4x + 1, the slope of the line m = 4
Substitute m = 4 and the point (-2, -5) into the equation above;
y - (-5) = 4(x - (-2))
y+5 = 4(x+2)
y+5 = 4x+8
y = 4x+8-5
y = 4x + 3
Hence the equation of the line is y = 4x+3

solve 2x+6=34 i have no idea pls exsplain and help me :)
Answers
First subtract 6 from both sides so you get 2x=28
Then divide both side by 2 so you get x=14 which is your answer :)
ANSWER: x=14
Answer:
14
Step-by-step explanation:
okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this
so you’re gonna start off by separating the 2x from the 6=34.
now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)
now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.
2 x 14 + 6 = 34?
2 x 14 = 28 + 6 = 34.
34 = 34
so, x is 14. hope this helped!
