Hi there! :)
Answer:
x = -7.
Step-by-step explanation:
Starting with:
3(2x + 2) = 3x - 15
Begin by distributing '3' with the terms inside of the parenthesis:
3(2x) + 3(2) = 3x - 15
Simplify:
6x + 6 = 3x - 15
Isolate the variable by subtracting '3x' from both sides:
6x - 3x + 6 = 3x - 3x - 15
3x + 6 = -15
Subtract 6 from both sides:
3x + 6 - 6 = -15 - 6
3x = -21
Divide both sides by 3:
3x/3 = -21/3
x = -7.
Sigma 960(1/4)^(i-1)
Since r^2<1, the sum is convergent and has a value of
960/(1-1/4)
960/(3/4)
4(960)/3
1280
6 x 9 x i = 54i
4(i) x 2(i) = 8i^2
54i +8i^2= 8i^2 +54i
Answer:
a). Point A
b). 90°
c). Anticlockwise
Step-by-step explanation:
As it's clear from the picture attached,
Triangle XYZ has been rotated about a point A to form an image X'Y'Z'.
Angle of rotation is 90° about a point A.
a). Point which is the center of the rotation → point A.
b). Angle of rotation → 90°
c). Direction of rotation → Anticlockwise
The answer would be C because 24-3=21 then you would do 21/1.50=14
