Answer:
68 ≥ t ≤ 770
Step-by-step explanation:
<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>1</u><u> </u><u>:</u>
replace x and y by their value 1 and 3
3 = 4(1) - 1 = 4-1 = 3
2(1) + 3 = 2 + 3 = 5
correct
<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>2</u><u> </u><u>:</u>
y = 4x - 1
2x + y = 5
y = 4x - 1
y = -2x + 5
y - y = 4x - 1 - ( -2x + 5 )
0 = 4x - 1 + 2x - 5
6x - 6 = 0
6x = 6
x = 6/6 = 1
y = 4x - 1
y = 4(1) - 1
y = 3
correct
Answer:
Step-by-step explanation:
Triangle 1,
Sum of the squares of the shorter lengths = 13² + 17²
= 169 + 289
= 458
Square of the longest length = 19² = 361
Since, sum of longest side is less than sum of squares of the smaller sides,
13²+ 17² > 19²
Therefore, it's acute triangle.
Triangle 2,
Sum of squares of the shorter lengths = 10² + 24²
= 576
Square of the largest length = 26² = 576
Since, sum of squares of the shorter lengths = square of the largest length
Therefore, it's a right triangle.
