Answer:
let x and y be two integers then this number line can be represented as linear equation with two variable
2x-3.1y= -1.1
here x and y could be 1
Answer:
m = - 1/4
Step-by-step explanation:
When two line is perpendicular to each other the product of them is - 1
So let the other line be B
Gradient of B = t
Gradient of A = 4
therefore m = - 1/4
First find the slope using (y1-y2)/(x1-x2)
(-2-4)/(5+16) = -6/21 or -2/7
Then plug in one of the points into y-y=m(x-x)
y + 2 = (-2/7)(x - 5)
Distribute the slope.
y + 2 = -2x/7 + 10/7
Subtract 2
y = -2x/7 - 4/7
So the answer is A.
First you would want to figure out how much tax would be
127 × 0.08 = 10.16
Then you add the tax to the original price
10.16 + 127 = 137.16
And now you have the total cost of the product
137.16
