Solve systems of equations by graphing. A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.
Answer:
y = -2x + 1
Step-by-step explanation:
First, find the slope with rise/run (y2 - y1) / (x2 - x1)
We can use the points (-1, 3) and (0, 1)
Plug in the points:
(1 - 3) / (0 + 1)
-2/1
= -2
The y-intercept is (0, 1) because that is the point where the line intercepts the y axis. So, we can plug in the slope and y-intercept into the equation:
y = mx + b
y = -2x + 1
Answer:
D. $66.23
Step-by-step explanation:
The sale discounts your purchase by half the price of a pair of pants, so you pay for 2.5 pairs of pants. The sale price of the pants is then ...
$24.99 × 2.5 = $62.48
The added tax multiplies this value by 1.06, so you pay ...
1.06 × $62.48 = $66.23
_____
<em>Comment on the answer</em>
Whether you pay $66.23 or $66.22 depends on how the discount is calculated. If you get the benefit of the half-penny (the discount is rounded up), then the sale price is $62.47 and the total is $66.22.
Answer:
In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign "=".[2][3][4] The word equation and its cognates in other languages may have subtly different meanings; for example, in French an équation is defined as containing one or more variables, while in English, any equality is an equation.[5]
