Answer:
y=a right angle triangle
y=50
Step-by-step explanation:
140-90
=50
if u add 90 and 50 it totals up to 140
they are vertically opposite triangles hope that helps
Answer:
<h2>
y = 4x - 9 </h2>
Step-by-step explanation:
The equation in point-slope form with slpope of m and including point (x₁,y₁) is:
y - y₁ = m(x - x₁)
m = 4
(3, 3) ⇒ x₁ = 3, y₁ = 3
So:
y - 3 = 4(x - 3) ← the point-slope form
y - 3 = 4x - 12 {add 3 to both sides}
y = 4x - 9 ← the slope-intercept form
Answer:
2048
Step-by-step explanation:
Time to use recursive formula :)
Since a of 1 = 4 and -the recursive formula is
-2(a of n-1) We know that the r = -2
Convert that to explicit is
f(n) = -2 * 4^n-1
Let's use that to get the value for a of 6.
f(6) = -2 * 4^6-1
= -2 * 4^5
= -2048
