To choose the graph, we must make sure that it satisfies both equations of the system simultaneously.
We have then:
a line includes points 0 comma 4 and 3 comma 5
Verifying:
(0, 4)
(0) - 3 (4) = -12
0-12 = -12
-12 = -12
(3, 5)
2x - y = 1
2 (3) - (5) = 1
6-5 = 1
1 = 1
answer
The graph that matches the system of equations is
a line includes points 0 comma 4 and 3 comma 5
The slope-intercept form:
m - slope
b - y-intercept
We have the slope 
and point (9, 7). Substitute:
<em>subtract 3 from both sides</em>
Answer: 
Answer:
$30
$90
Step-by-step explanation:
Given parameters:
Selling price of belt = $120
Percentage discount = 25%
Unknown:
Discount = ?
Sale price of the dress = ?
Solution:
Discount is a reduction in the price of a commodity.
Discount = percentage discount x selling price of belt
Input the parameters and solve;
I. Discount = 
x 120 = $30
II. Sale price of the dress;
= selling price - discount amount
= $120 - $30
= $90
Okay, well for a right triangle with legs a and b and hypotenuse c we have:
a2+b2= c2
since we know the hypotenuse (c), we have:
a2+b2= 25
since the short leg is 1 inch shorter than the longer leg,
we can say that a = b-1
So now we have:
(b-1)2+ b2 = 25
b2 - 2b +1 +b2 = 25
2b2-2b -24 = 0
2(b2-b-12) = 0
b2-b-12 = 0
(b-4)(b+3) = 0
Because you can't have a negative length, b = 4
If b = 4, then a = 4-1 = 3
So,
b=4
a=3
