Answer:
Look at steps
Step-by-step explanation:
STATEMENT REASON
1. AB = CD; AD = CB 1. Given
2. AC = AC 2. Identity property
(AC is the common side of the two triangles)
3. Triangle ABC = Triangle ADC 3. SSS (Side-Side-Side)
4. ∠1 = ∠4 4. Alternative interior angles are equal (Two lines are parallel and cut by transversal)
5. DC || AB 5. Since alternative interior angles are (Two lines are parallel and cut by transversal)
equal, the lines DC and AB are
parallel by transversal property.
Thank you:)
Answer:
1) (2, 3)
2) (2, -5).
Step-by-step explanation:
2x – y = 1
2x +2y = 10 Subtract to eliminate the 2x:
2x - 2x - y - 2y = 1 - 10
-3y = -9
y = 3.
Plug this into the first equation:
2x - 3 = 1
2x = 4
x = 2.
2)
5x – y =15
x + y = -3 Adding to eliminate y:
5x + x - y + y = 15 + -3
6x = 12
x = 2
Plug this into the first equation:
5(2) - y = 15
-y = 15 - 10 = 5
y = -5.

(where m is miles)
Step-by-step explanation:
He can go a maximum of 250 miles on a tank of gas (25 miles per gallon * 10 gallons), and this can be expressed as follows:
m ≤ 250
