Step-by-step explanation:
For number 1.
If x = -2.
y = 4x + 3 = 4(-2) + 3 = -8 + 3 = -5
If x = 3
y = 4x + 3 = 4(3) + 3 = 12 + 3 = 15
If x = -4
y = 4x + 3 = 4(-4) + 3 = -16 + 3 = -13
If x = -5
y = 4x + 3 = 4(-5) + 3 = -20 + 3 = -17
If x = 5
y = 4(x) + 3 = 4(5) + 3 = 20 + 3 = 23
For number 2.
If x = -2
[tex]y = x^{2} + 4 + 2x = (-2)^{2} + 4 + 2(-2) = 4 + 4 - 4 = 4[/tex]
If x = 3
[tex]y = x^{2} + 4 + 2x = (3)^{2} + 4 + 2(3) = 9 + 4 + 6 = 19[/tex]
If x = -3
[tex]y = x^{2} + 4 + 2x = (-3)^{2} + 4 + 2(-3) = 9 + 4 - 6 = 7[/tex]
If x = 4
[tex]y = x^{2} + 4 + 2x = (4)^{2} + 4 + 2(4) = 16 + 4 + 8 = 28[/tex]
If x = -4
[tex]y = x^{2} + 4 + 2x = (-4)^{2} + 4 + 2(-4) = 16 + 4 -8 = 12[/tex]

Answers
Answer:
-3.33333
Step-by-step explanation:
-3w - 4 = 3 + 3
Combine like terms
-3w - 4 = 6
Add 4 on both sides
-3w - 4 + 4 = 6 + 4
-3w = 10
Divide by -1 to isolate the variable
-3w/-3 = 10/-3

Suzy has a collection of quarters and dimes. Together she has 34 coins worth $6.40. How many quarters and how many dimes does Suzy have?
Please show your work :)
Answers
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14

What is the sum of the measures of the interior angles of a 7-gon?
Answers
Answer:
900°
Step-by-step explanation:
What is the sum of the measures of the interior angles of a 7-gon?
The formula to measure the interior angles of a polygon
= (n- 2) × 180 °
Where,
n = number of sides
We are given 7 - gon
This means it has 7 sides = Heptagon
Hence,
The measure of the interior angle is given as:
(7 - 2) × 180°
= 5 × 180°
= 900°
The sum of the interior angles of a 7-gon is 900°

Let x represent the maximum and minimum time.
|x-20|=35
|x+20|=35
|x+35|=20
|x-35|=20
Answers
B. |x+20|=35
This is because 20 is the minimum time, so you have to add that to whatever x is. since x can be the minimum or maximum, this further proves this statement. You can also know this is correct because the final product (35) was the maximum time shown in the world problem

In-center of a triangle,In-center of a triangle defines the center of a circle inscribed in the triangles (touching all sides),Perpendicular drawn from in-center to the sides of the are equal in measures (radii of the inscribed circle).Use the hint → Area of the large triangle = sum of the small triangles inside the larger triangle
Area of ΔABC = [tex]\frac{1}{2}(AB)(AC)[/tex]
Area of ΔADC = [tex]\frac{1}{2}(AC)(x)[/tex]
Area of ΔBDC = [tex]\frac{1}{2}(BC)(x)[/tex]
Area of ΔADB = [tex]\frac{1}{2}(AB)(x)[/tex]
Since, Area of ΔABC = Area of ΔADC + Area of ΔBDC + Area of ΔADB
[tex]\frac{1}{2}(AB)(AC)=\frac{1}{2}(AC)(x)+\frac{1}{2}(BC)(x)+\frac{1}{2}(AB)(x)[/tex]
[tex](AB)(AC)=[(AC)+(BC)+(AB)](x)[/tex]
[tex]x=\frac{(AB)(AC)}{AC+BC+AB}[/tex]
Therefore, expression representing the length 'x' will be [tex]x=\frac{(AB)(AC)}{AC+BC+AB}[/tex].
