Answer:
1. 3
2. -2
3. (1, 2)
Step-by-step explanation:
y axis is the numbered line that looks like the |
x axis is _
so the y int is 3 because A intercepts the y axis at 3
the y int for B is -2 because it intercepts the y axis at -2
the intersection of both lines is (1, 2) because you look and the point is at 1 for x and 2 for y
I think it might be the 3rd option
Step-by-step explanation:
The answer is d, 80 degrees
Answer:
Yes: A, B, F
No: C, D, E
Step-by-step explanation:
2(x + 7) = 36
First divide both sides by 2
(x + 7) = 36/2
x + 7 = 18
Or
2(x + 7) = 36
2x + 14 = 36
Or,
2(x) + 2(7) = 36
422₅ - 143₅ = 224₅
We convert each number to base 10.
So 422₅ = 4 × 5² + 2 × 5¹ + 2 × 5⁰
= 4 × 25 + 2 × 5 + 2 × 1
= 100 + 10 + 2
= 112₁₀
143₅ = 1 × 5² + 4 × 5¹ + 3 × 5⁰
= 1 × 25 + 4 × 5 + 3 × 1
= 25 + 20 + 3
= 48₁₀
So 422₅ - 143₅ = 112₁₀ - 48₁₀ = 64₁₀
We now convert 64₁₀ to base 5
64 ÷ 5 = 12 r 4,
12 ÷ 5 = 2 r 2
2 ÷ 5 = 0 r 2
Counting upwards,
So, 65₁₀ = 224₅
So, 422₅ - 143₅ = 224₅
