Answer:
y = -1/2 x + 2
Step-by-step explanation:
Which of the following equations describes the line shown below? Check all
that apply.
(-4, 4)
(2, 1)
The standard equation of a line is y = mx,+b
m is the slope
b is he y-inttercept
Get the slope
Slope m = y2-y1/x2-x1
Substitute the coordinate
M = 1-4/2-(-4)
M = -3/6
M = -1/2
Substitute m= -1/2 and (2,1) into y = mx+b
1 = -1/2(2)+b
1 = -1+b
b = 1+1
b=2
Get the equation
Recall y =mx+b
y = -1/2 x + 2
Answer:
$20.60
Step-by-step explanation:
Price before discount = $21
Discount rate = 10% or 0.1
Discount in dollars = 0.1* 21 = $2.1
Price after discount = $21 -$2.1 = <em>$18.90</em>
If sales tax is 9% or 0.09
amount of tax will be = 0.09 * 18.90 = <em>$1.701</em>
Total price of the phone including taxes = Price before tax + tax amount;
Total price = 18.90 +1.701
= 20.601
Therefore total price will be $20.60
Answer:
option C
15 14
-1 9
Step-by-step explanation:
Given in the question a 2x3 and 3x2 matrix
Since, the column of first matrix and row of second matrix is of equal integer, 3, so we can multiply them.
The resultant matrix will be of 2x2
We will use dot product
1(2) + 3(3) + 1(4) 1(-2) + 3(5) + 1(1)
-2(2) + 1(3) + 0(4) -2(-2) + 1(5) + 0(1)
15 14
-1 9
