Step-by-step explanation:
21
Answer:
3
Step-by-step explanation:
the slope of an equation (y=mx+b) is always "m", or the coefficient right infront of x. in this case, y=3x-7, 3=m, -7=b. m is the slope, so the slope is 3.
Answer and explanation:
Statement - If the difference of two numbers is even then so is their sum.
Let the two even numbers be '2m' and '2n' with m and n are integers.
The difference of two number is

Now, The sum of the numbers is

Let
where k is an integer
Then,
which is also an even number as 2 is multiplied with it.
So, If the difference of two numbers is even then so is their sum.
For example -
Let two even number 2 and 4.
The difference is
, 2 is even.
The sum is
, 6 is even.
The criteria to find out the x-intercept of the line is we find out the result when
y = 0
- 2x + 5y = -20
- 2x + 0 = -20
x = -20 / -2
x = 10

Answer:
D. scalene triangle
Step-by-step explanation:
This triangle has sides that all have different lengths. Therefore, this triangle is a scalene triangle.
Tips:
Isosceles triangle - two sides have equal lengths
Equilateral triangle - all three sides have equal lengths
