Answer:
y = 2x +13
Step-by-step explanation:
when 2 lines are perpendicular, the product of the two gradients is -1
i.e. m x m1 = -1
so from 10y + 5x = 3, the gradient m is -0.5
m1 = -1 / -0.5 = 2
using m1 = 2 and pt(-7,-1),
the eqn is y = (m1)x +c
-1 = 2(-7) + c
c= 13
thus y = 2x +13
So what makes a function a function is that each input (x) only has one output (y).
Set A is not a function because when x = 2, y = -2 and 3.
Set B is not a function because when x = 9, y = 3 and -3.
In short, the correct option is "Neither A nor B".
Answer:
52
Step-by-step explanation:
You have 8 eight hours and 416miles, and you need to distribute those 416 miles to eight hours. so 416/8=52
Answer:
y = x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (4, 2 ) and (x₂, y₂ ) = (0, - 2 )
m = 
= 
= 1
the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2
y = x - 2 ← equation of line
The estimate of the percentage expression 66 2/3% of 2,600 is 1733.33
<h3>How to estimate the percentage expression?</h3>
The expression is given as:
66 2/3% of 2,600
Rewrite as:
66 2/3% * 2,600
Express the fraction as an improper fraction
200/3% * 2,600
Remove the percentage sign
200/300 * 2,600
Evaluate the product
1733.33
Hence, the estimate of the percentage expression 66 2/3% of 2,600 is 1733.33
