Answer:
(-2,-5)
Step-by-step explanation:
y = 2x-1
3x-y = -1
We can use substitution
3x - (2x-1) = -1
Distribute the minus sign
3x -2x+1 = -1
x +1 =-1
Subtract 1 from each side
x+1-1 = -1-1
x=-2
Now we need to find y
y = 2x-1
y = 2(-2) -1
y = -4-1
y = -5
(-2,-5)
None of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.
<h3>Properties of an Isosceles Triangle</h3>
- An isosceles triangle has two base angles having equal angle measure.
- The side lengths that are opposite each of the equal base angles are also congruent to each other.
Thus, none of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.

1. Multiply 10 and 1, then add 9. Then the fraction will be 19/10.
2. Multiply 19/10 and (-5/9). That will give you -95/90, which reduces to -19/18
3. Add -19/18 and 7/3.
4. The answer is 23/18
Answer:
x - 24 > 9
x > 33

Answer:
y = 4/5 x - 2 1/5
Step-by-step explanation:
1. Find the slope:
<u>1 - 5 </u> = <u> -4 </u> = <u> </u><u>4 </u>= m
4 - 9 -5 5
2. Find b by plugging in the slope you just found and one of the points given into y = mx + b
1 = 4/5 ( 4) + b
1 = 16/5 + b
- 2 1/5 = b
3. Plug in the m and the b you found into y = mx + b
y = 4/5 x - 2 1/5
