Assignment name: solving angles pairs
Answer:
x = 26
Step-by-step explanation:
Alternate exterior angles are always congruent
3x - 8 = 70
Add 8 to both sides;
3x = 78
Divide both sides by 3;
x = 26
Can someone please help me with this last one. I am totally lost and don’t understand
Answer:
g(-4) = -1
g(-1) = -1
g(1) = 3
Explanation:
If you are given a function that is defined by a system of equations associated with certain intervals of x, just find which interval makes x true, and then substitute x into the equation of that interval.
For example, given g(-4), this is an expression which is asking for the value of the equation when x = -4. So -4 is not ≥ 2, so ¼x - 1 will not be used. -4 is also not ≤ -1 and ≤ 2, so -(x - 1)² + 3 will not be used either. So in turn, we will just use -1 which is always -1 so g(-4) will just be -1, right because there is no x variable in -1 so it will always be the same.
Using the same idea as before g(-1) is g(x) when x = -1 so -1 will not be a solution because -1 is not less than -1 (< -1). -1 is not ≥ 2 either so we will be using the second equation because -1 is part of the interval -1≤x≤2 (it is a solution to this inequality), therefore -(x - 1)² + 3 will be used.
As x = -1, -(x - 1)² + 3 = -(-1 - 1)² + 3 = -(-2)² + 3 = -4 + 3 = -1.
It is a coincidence that g(-1) = -1.
Now for g(1), where g(x) has an input of 1 or the value of the function where x = 1, we will not use the first equation because x = 1 → x < -1 → 1 < -1 [this is false because 1 is never less than -1], so we will not use -1.
We will use -(x - 1)² + 3 again because 1 is not ≥ 2, 1≥2 [this is also false]. And -1 ≤ 1 < 2 [This is a true statement]. Therefore g(1) = -(1 - 1)² + 3 = -(0)² + 3 = 3

amount she should spend each day. $________?
I’m confused
Answer:
The most she can use in a day is $4.55.
Step-by-step explanation:
The explanation is simple.
22.75 divided by 5 = 4.55
Mark as Brainliest!
Answer:
$4.55
Step-by-step explanation:
All you do is take the total amount Sadie has right now and divide it by how many days it needs to last.
$22.75/5=$4.55
So Sadie can only spend $$.55 a day for the 5 days.
Two similar triangles are in the ratio 2:3. If the sides of the bigger triangle are 15 units, 12 units and 9 units, then the length of the shortest side of the smaller triangle is
a. 8 units
b. 6 units
c. 9 units
d. 5 units
It is 6 units because if you divide 9 by 3 you get 3 and you multiple that by 2 to make it 6:9 which is equal to 2:3

Answer:
-3x
Step-by-step explanation:
Subtract 2 from 5
Hope this helped, Have a great day!!
Answer:
-3x
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of variables. Note that both terms (2x & -5x) both have one x in all.
Subtract the coefficients:
2x - 5x = -3x
-3x is your answer.

General Formulas and Concepts:
Pre-Algebra
Distributive PropertyAlgebra I
Combining like termsStep-by-step explanation:
Step 1: Define
f(x) = 4x - 8
g(x) = x - 2
(f - g)(x) is f(x) - g(x)
Step 2: Find
Substitute: (f - g)(x) = 4x - 8 - (x - 2)Distribute negative: (f - g)(x) = 4x - 8 - x + 2Combine like terms: (f - g)(x) = 3x - 6Evaluate the expression (10 x 7} + (10 - 6).

Li is making beaded necklaces. For each necklace, she uses 34 spacers, plus 7 beads per inch of necklace length. Write an equation to find how many beads Li needs for each necklace, where x is the length, in inches, of the necklace. The equation that represents this situation is y =
Answer: Y = 7x+34
Explanation : if there are 7 beads per inch that means that for every inch there are 7 more beads. and the 34 for is an unchangeable factor that stays the same throughout the equation

A 52kg person walks from the ground to the roof of 78.52m tall building. How much gravitational potential energy is there?USE GRESA METHOD
Answer:
P = 40013.792 J
Step-by-step explanation:
Given that,
Mass of a person, m = 52 kg
The height of the building, h = 78.52 m
We need to find the gravitational potential energy at this point. It is given by the formula as follows :
P = mgh
Where g is acceleration due to gravity
P = 52 kg × 9.8 m/s² × 78.52 m
P = 40013.792 J
So, the gravitational potential energy is 40013.792 J.
