The answer is A because the two points have the same value. Then it would not pass the state of the line test. your answer is A
Answer:
y-intercept: (0,-3)
Step-by-step explanation:
- Y-intercepts mean that the x-value has to be equal to 0. When plugging in 0 for the x-value, we receive:
- Therefore, the point is (0,-3).
Step-by-step explanation:
1. No: angles add to more than 180 deg.
2. Yes: each side's length is between the sum and difference of the lengths of the other two sides.
3. No: not every side's length is between the sum and difference of the lengths of the other two sides.
4. Yes: for example, place the 50 deg angle between the two given sides. Another side will then make the triangle.
5. Yes: for example, use 3 cm as the short leg in a 30-60-90 right triangle.
Answer:
144 cm^3
Step-by-step explanation:
The formula for the volume of a rectangular prism is <em>l x w x h. </em>
Here, the length is 4, the width is 4, and the height is 4.
4 x 4 x 9 =
16 x 9 =
144 cm^3
So y+x=2
x-y=4
one way is subsituteion where yousubisutte one of the number for another exg
x-y=4
add y to both sides
x=y+4
subsitute y+4 for x in x+y=2
y+4+y=2
2y+4=2
subtract 4 from both sides
2y=-2
divide both sides by 2
y=-1
subsiutte
x+y=2
x-1=2
x=3
or elimination
x+y=2
x-y=4
add the two equations and cancel the y terms
x+x+y-y=2+4
2x=6
divide both sides by 2
x==3
subsitute
x+y=2
3+y=2
y=-1
so x=3
y=-1
