Answer:
y=2x+13
Step-by-step explanation:
Gradient of parallel lines are equal and in the equation,y=2x-5, 2 represents the gradient.
Therefore the gradient of the other line will also be 2.
Introduce another point (x,y) and then equate using the gradient as follows:
y-1/x--6=2
y-1/x+6=2
Cross multiplication;
(y-1)=2(x+6)
y-1=2x+12
y=2x+12+1
y=2x+13
Answer:
-7
Step-by-step explanation:
y=-7x+9
y=mx+b
m=slope
y=y-intercept
Answer:
(9, 6)
Step-by-step explanation:
<u>Midpoint formula is:</u>
- x = (x₁ + x₂)/2
- y = (y₁ + y₂)/2
<u>Having coordinates of one end- and midpoint </u>(-5, 12) <u>and</u> (2, 9)<u>:</u>
- x₁ = -5, y₁ = 12
- x = 2, y = 9
<u>we get the coordinates of the missing endpoint with coordinates</u> (x₂, y₂):
- x₂ = 2x - x₁ = 2*2 - (-5) = 4 + 5 = 9
- y₂ = 2y - y₁ = 2*9 - 12 = 18 - 12 = 6
<u>So the missing point is</u>: (9, 6)
Cathy and Iris have 259,459,200 ways to skip countries.
Data;
- Number of countries they are planning to visit = 9
- Number of countries they would like to visit = 13
<h3>Combination</h3>
To solve this problem, we would have to use a mathematical procedure known as combination.
Let us calculate the number of countries that would have to skip.
To decide which country they have to skip, it would be 4 out of 13.
Let's solve this
