Answer:
Step-by-step explanation:
B i think
C
Step-by-step explanation:
You do 5 - 2 = 3 and -y = -x so the answer would be C.
Answer:
x = the first mystery number = 2
y = the second mystery number = 0.8
Step-by-step explanation:
Let
x = the first mystery number
y = the second mystery number
8*x + 10*y = 24
8x + 10y = 24
7*x + 10*y = 26
7x + 10y = 26
8x + 10y = 24 (1)
7x + 10y = 26 (2)
Subtract (1) from (2) to eliminate y
8x - 7x = 26 - 24
x = 2
Substitute x = 2 into (1)
8x + 10y = 24 (1)
8(2) + 10y = 24
16 + 10y = 24
10y = 24 - 16
10y = 8
y = 8/10
y = 0.8
x = the first mystery number = 2
y = the second mystery number = 0.8
Slope = -10
<span>pass through (2,-5)
y = mx + b
so
b = y - mx
b = -6 - (-10) (2)
b = -6 + 20
b = 14
equation
y = -10x + 14</span>
