Answer:
1/3
Step-by-step explanation:
Slope = ( y₂ - y₁ ) ÷ ( x₂ - x₁ )
y₂ = 9
y₁ = 7
x₂ = 4
x₁ = -2
y₂ - y₁ = 9 - 7 = 2
x₂ - x₁ = 4 - -2 = 6
2 ÷ 6 = 1/3
Each pair of numbers gives a value then another value that is 1/2 of the first. So the answer would be
6 = 3
1. Alternate exterior angles
So, C
2.
180 = 76 + 2x
104 = 2x
52 = x
So, B
4.
4a. No
4b. Yes
4c. No
4d. Yes
5.
180 = 35 + 35 + 2x
180 = 70 + 2x
110 = 2x
55 = x
So, C.
7.
12/8 = 30/y
Cross multiply
12y = 240
y = 20
So, C
8. Alternate interior angles
So, A
9.
A C and D
Step-by-step explanation:
ab
= (5⁹⁹ * 2⁹⁸) * (5⁷² * 4³⁸)
= 2⁹⁸ * 2⁷⁶ * 5⁹⁹ * 5⁷²
= 2¹⁷⁴ * 5¹⁷¹
= 2³ * (2¹⁷¹ * 5¹⁷¹).
The 2¹⁷¹ * 5¹⁷¹ will give 171 ending zeroes as 2 * 5 = 10.
And there is a 8 infront as 2³ = 8.
Hence altogether there are 171 + 1 = 172 digits.
X=3. 33x-21x equals 12x. 24+12=36. 12x divided by 36 equals 3
