Answer:
x = -5
y = 2
Step-by-step explanation:
x = – 2y – 1
= -x - 2y - 1
-x - 2y = 1
x = – 5y + 5
= -x - 5y + 5
-x - 5y = -5
-x - 2y = 1
-x - 5y = -5
___________--
3y = 6
y = 6/3
<u>y = 2</u>
-x - 2y = 1
-x - 2(2) = 1
-x - 4 = 1
-x = 1 + 4
-x = 5
<u>x = -5</u>
If one element in the domain mapped with more then one element in the range, the mapping is called one-to-many relation. One-to-many relations are not functions. Example: Draw a mapping diagram for the function f(x)=2x2+3 in the set of real numbers.
Answer:
Graph B
Step-by-step explanation:
The <em>mass</em><em> </em>is independent, so it runs <em>horizontally</em>,<em> </em>and the <em>fuel</em> is dependent, so it runs <em>vertically</em>.

Answer:
The Blue box is your answer
Step-by-step explanation:
Multiply 4, 8, and 7 and you get 224. The problem states that it should not be over 250, and 224 is not over 250. So the blue box is your best go.
The slope intercept form of this would be y=*3x-1. The formula for slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. I this problem, the y-intercept is -1, so you would plug in -1 for b, so the equation is y=mx-1. The slope is -3, so you plug that in for m, so the equation now becomes y=-3x-1. Hope that helps!!
