X+3y=14
-x. -x
3y=-x+14
Divide them all by 3
Y=-x/3+14/3
Y-intercept= 1/3
Answer:
2√2
Step-by-step explanation:
<u>By </u><u>using </u><u>trigonometry,</u>
sin 45° = x/4
x = 4sin 45°
x = 2√2
<u>By </u><u>using </u><u>Pythagorean</u><u> </u><u>theorem</u><u>,</u>
Since you know that it is an isosceles triangle and it's also a right-angled triangle,
4² = x² + x²
16 = 2x²
x² = 8
x = √8
= 2√2
Answer:3x+6=2x+21 base angle of isosceles triangle
3x-2x=21-6
X=15
<J=3×15+6=51
<k=2×15+21=51
,<I=180-51-51=78
Step-by-step explanation:
Y²(9y² + 4y - 9)
Simplify.
(y² · 9y²) + (y² · 4y) + (y² · -9)
Simplify.
9y⁴ + 4y³ - 9y²
