c is 2 6
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1) Slope = rise over run. You can pick any two points on a line to calculate the slope. You can double check your answer by trying different points on the line. If the line is going up, from left to right, the slope is positive.

A sales item is 20% off. If the final price of the item was $560.00, what was the original price of the item?
Answers
Answer:
700
Step-by-step explanation:
price x .80 (100%-20)=560
price=560/.8
price=700
The item's initial cost before taxes is $700.
What is the percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, A sales item is 20% off. If the final price of the item was $560.00
Let "x" be the original price of the item
Since If the final price of the item was $560.00
Thus,
x(1 - 20%) = 560
x(1- 20/100) = 560
x(80/100) = 560
x = 700
therefore, The original price of the item without tax will be $700.

the diagram shows an isosceles triangle. all measurements are in cm.
3x-5 19-x
2x
work out the perimeter of the triangle
Answers
Answer: 38
Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6
Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12
Two equal sides are 13 and base 12
Perimeter is 13 + 13 + 12 = 38 units
Answer is: 38
The perimeter of the given isosceles triangle is 38 cm.
What is the perimeter of an isosceles triangle?The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;
We can say that the perimeter of an isosceles triangle is:
P = 2a + b
where;
a = sides of the base anglesb = third side3x - 5 = 19 - x
3x + x = 19 + 5
4x = 24
x = 24/4
x = 6
The perimeter of the isosceles triangle is:
= 3x - 5 + 19 - x + 2x
= 3(6) - 5 + 19 - 6 + 2(6)
= 18 + 8 + 12
= 38 cm

do I add multiply, add, subtract ? I need help!
Answers
Answer:
x=35
Step-by-step explanation:
you are going to want to subtract. the best thing about triangle angles is that they all add to equal 180º no matter what. so what you can do is subtract the given angles from 180. so 180-80-65. which gives us 35.
Hope this helps!
Answer:
I believe you add, degrees in triangles are 180 so 80+65= 145. 180-145 is 35

f(x) = 4x2 + 5x - 3
g(x) = 4x2 – 3x2 + 5
Find (f +g)(x).
Answers
Answer:
5x + 12
Step-by-step explanation:
simplify f(x) and g(x)
g(x) = 4*2 -3*2 +5
g(x) = 8 -6 + 5
g(x) = 7
and
f(x) = 4*2 + 5x -3
f(x) = 8 + 5x - 3
f(x) = 5x + 5
So (f + g)(x) = f(x) + g(x)
(f + g)(x) = (5x + 5) + (7)
(f + g)(x) = 5x + 12
