Answer:
C
Step-by-step explanation:
Convert to slope intercept form:
y = mx + b
2x + y = 7
y + 2x = 7
y + 2x - 2x = 7 - 2x
y + 0x = -2x + 7
y = -2x + 7
Slope = -2
Y-intercept = 7
Answer:
+ 121
Step-by-step explanation:
A function f(x) divided by (x - h) has remainder f(h)
Given
f(x) = 2 - x - 5 divided by (x - 2) then remainder is f(2), thus
f(2) = 2 - 2 - 5 = 2(64) - 7 = 128 - 7 = 121
-12i * 3i
= -12*3 *i*i
= -36i² but i² = -1
= -36*-1
= 36
We know that cos A = 0.34.
We have to find the measure of ∠ A in degrees ( and to round it to the nearest hundredth ):
∠ A = cos^(-1) 0.34 = 70.12313° ≈ 70.12°
Proof: cos 70.12° ≈ 0.34
Answer:
∠ A = 70.12°
Answer:
x=7
Step-by-step explanation:
Starting with (x-2)² = 25
First, square root both sides to get rid of the square on the left. You'll get:
x-2 = 5
Add 2 to both sides to get x alone. You'll get:
x=7
Check your answer by filling in 7 for x:
(7-2)² = 25
(5)² = 25
25 = 25
