Answer:
2s-?
Step-by-step explanation:
s0rry if its wr0ng but i think y0u d0 6s-4=2s.
They are equal because
1 yd=3ft
25 yds= x feet
x= 25*3
feet=75
Answer:
-14
Step-by-step explanation:
a(3)=a(2)-17=a(1)-17-17=20-17-17=-14
Answer:
1. -2, 2. -23, 3. 25
Step-by-step explanation:
1. -2+5x8/-12= step 1: add -2+5
-2+5=3 step 2: 3(8)
3x8= 24 step 3: 24/-12
24/-12= -2
2. -2(9-4)+3=? step 1: combine like terms -2(9) and -2(-4)
-18-8+3=? step 2: combine like terms
-26+3=? step 3: combine like terms
-23=?
3. 2x + 130=180 step 1: -130 on both sides
2x = 50 step 2: /2 on both sides
x = 25
Answer:
x = 0
Step-by-step explanation:
The argument x+3π/2 shifts the sine function 3π/2 to the left, making it equivalent to -cos(x). Then the equation becomes ...
-2cos(x) = -2
cos(x) = 1
On the interval [0, 2π), cos(x) is only 1 at x=0.
