6. Equilateral
7. Scalene

Please answer the following questions 1 2 and 3 with showing your work fully!
Answers
Answer:
1. Point of intersection = (4, 360)
2. (4, 360) number of hours and the total cost of the repairs is the same for both repair shops
3. Amy's Auto Repair: $280
Step-by-step explanation:
1. y = 100 + 65x and y = 40 + 80x
Equate the equations and solve for x:
y = y ⇒ 100 + 65x = 40 + 80x
subtract 65x from both sides ⇒ 100 = 40 + 15x
subtract 40 from both sides ⇒ 60 = 15x
divide both sides by 15 ⇒ 4 = x
Therefore, x = 4
Substitute x = 4 into either of the equations to find y:
⇒ y = 40 + (80 x 4) = 40 + 320 = 360
Point of intersection = (4, 360)
2. The two lines intersect at (4, 360)
In this context, the point of intersection is where the number of hours and the total cost of the repairs is the same for both repair shops.
3. Substitute x = 3 into the equations and compare:
Mike's repair shop: y = 100 + (65 x 3) = 295
Amy's auto repair: y = 40 + (80 x 3) = 280
Therefore, Amy's Auto Repair is the cheapest (as 280 < 295) and the cost is $280.

8 meters is equivalent to the fraction 2/5 of 20 meters.
Given that:
Given part, 8 meters
And whole part, 20 meters
To express 8 meters as a fraction of 20 meters, simply divide the given part by the whole.
The formula is given below,
Fraction = (Part) / (Whole)
Put the given values in above formula and calculated as:
Fraction = (Part) / (Whole)
Fraction = 8 m / 20 m
Now, simplify the fraction by canceling out the common factor of 4:
Fraction = (8 m / 4) / (20 m / 4)
Fraction = 2 m / 5 m
So, 8 meters is equivalent to the fraction 2/5 of 20 meters.

What multiplies to give you 15 and adds to give you -8?
Answers
Answer:
-5 and -3 because if you multiply both the answer is 15 and if you plus both the answer is -8.
Step-by-step explanation:
Take one number as x.
Given,
x + ? = -8
? = - 8 - x
So, second number is -8 - x
Now,
x ( -8 - x) = 15
-8x - x² = 15
-8x - x² - 15 = 0
-x² - 8x - 15 = 0
(-x² - 3x) + (5x - 15) = 0
x (-x - 3) + 5 (-x - 3) = 0
(- x - 3)(x + 5) = 0

(SAT Prep) If the lengths of two sides of a triangle measure 8 and 13 what could the length of the third side measure
(A) 6
(B) 21
(C) 3
(D) 4
Hint its not D.
Answers
Answer:
A)6
Step-by-step explanation:
Use the triangle inequality theorem, which states that the third side of a triangle can not be greater than or equal to the sum of the other two sides, and can be no less than the or equal to the difference of the two other sides.
The sum is 8+13=21
The difference is 13-8=5
So if we call our third side x, then
[tex]5
If the lengths of two sides of a triangle measure 8 and 13 units, using triangle inequality theorem, the length of the third side could be 6 units.
What is triangle inequality theorem?The triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.
Given the two sides be 8 and 13 units.
Let the third side be x units.
First,
8 + 13 > x
21 > x
x < 21
Second,
8 + x > 13
x > 5
Third,
13 + x > 8
True for all values of x.
So,
5 < x < 21
From the given options, only 6 satisfies our condition.
