Answer:
x = -1, y= -5
Step-by-step explanation:
y=-x-6
y=x-4
Since both equations are equal to y we can set them equal to each other
-x-6 = x-4
Add x to each side
-x-6+x = x-4+x
-6 = 2x-4
Add 4 to each side
-6+4 = 2x-4+4
-2 =2x
Divide by 2
-2/2 = 2x/2
-1 = x
now find y
y = x-4
y = -1-4
y = -5
(100/15)x493=$3286.67 (rounded to 2 decimal places)
The one above is wrong.
This is the correct way:
(100/85)×493=580
Correct answer is $580
Answer:
See attachment :D
Step-by-step explanation:
y = 2/3x + 2
This is in slope-intercept form, y = mx+b. m is the slope, 2/3, and b is the y- intercept, 2. So you know the line intersects with the y-axis at (0,2). The slope is 2/3. So you can move up two points, then over three. Because it's a positive slope, you move right. This leaves you at point (0,3). Connect a line between these two points.
The line intersects with points (-3,0) and (0,2).
Hope this is helpful ^^ Good luck with your test :D
Answer:
A
Step-by-step explanation:
Use Pythagorean Theorem, which is for side lengths of right triangles.
a^2 + b^2 = c^2 (c is the hypotenuse)
Common combination is 3-4-5. Just by looking at the answers, I can see A is 3-4-5 except everything is multiplied by 2.
B is wrong. It would be 5-12-13 if it were a RT.
C is wrong. 3-4-5
D is wrong. 4 + 25 = 49 is not an equation.
