The answer is is 17x. I hope this helps
Answer:
See the attachment for the appropriate choice.
Step-by-step explanation:
Both equations are in slope-intercept form. Both have a y-intercept of -2, so only a graph where the lines cross at (x, y) = (0, -2) is a viable choice.
In both cases, the inequality requires that values of y be "less than (or equal to)" those described by the line. Hence, the shading will be below both lines.
Let n = the number of nickels that Ari has.
Let p = the number of pennies that Ari has.
The total number of coins she has is 22.
n + p = 22
We have our first equation... But we another one to solve this.
Each penny is going to be $0.01 and a nickel is work $0.05.
And the total is $0.54
Our second equation. 0.05n + 0.01p = 0.54
n + p = 22
0.05n + 0.01p = 0.54
Multiply the top by -0.05
-0.05n - 0.05p = -1.1
0.05n + 0.01p = 0.54
The n terms cancel out.
-0.04p = -0.56
p = 14
Substitute p back into the top equation.
n + 14 = 22
n = 8
So, Ari has 8 nickels and 14 pennies.
Answer:
-2 & 3/2
Step-by-step explanation:
=> -4x - 2y = -3
=> -4x + 3 = 2y
=> (-4/2)x + (3/2) = y
Compare this to y=mx+c
m=slope = -4/2 = - 2
y-intercept = c = 3/2
