Hey there,

This is a two-step problem and two equations are involved in figuring out the problems.

Looking at the points you know the y-intercept of both equations but you would need to solve for the slope.

First Step:

  • \frac{0-(-3) }{1-3 } = \frac{3}{-2}

The slope of the first equation would be -\frac{3}{2} now we write it in slope intercept form and get y = -\frac{3}{2} x + 1.

Second Step:

Perpendicular lines have slopes that are the negative reciprocal of the original line. So the perpendicular line would have the slope as \frac{2}{3} .

The equation would be: y = \frac{2}{3} x - 2

Hope I helped,

Amna

Mr. Hayden's Bible class collected $11
ki77a [65]

This is the only way I can think of this mathematically. This took a good 20 minutes for me. You need to guess and check. Like try 17 quarters, 50 nickels, and 37 dimes etc. until you get 11.00. My numbers are mathematically correct but we both know you cant have 18.909 quarters so. lol

Answer:

Quarters: 18.909

Nickels: 49.818

Dimes: 37.818

Somewhere around those numbers.

Step-by-step explanation:

$11.00 total in coins

Nickel = $0.05

Dime = $0.10

Quarter = $0.25

(n*0.05) + (d*0.10) + (q*0.25)

Solve the equation for q.

q=\frac{1}{2} d

(n*0.05) + (d*0.10) +( \frac{1}{2} d *0.25)

Simplify the expression.

9d + 2n = 440

d - n = -12

Multiply both sides of the equation by -9.

-9d + 9n = 108

9d + 2n = 440

Sum the equations vertically to eliminate at least one variable.

11n = 548

n=\frac{548}{11}

Substitute the given value of n into the equation d - n = -12

d-\frac{548}{11} =-12

d=\frac{416}{11}

Substitute the given value of n into the equation q=\frac{1}{2} d

q=\frac{1}{2} *\frac{416}{11}

q=\frac{208}{11}

Finally

d=\frac{416}{11}        d = 37.818

n=\frac{548}{11}        n = 49.818

q=\frac{208}{11}        q = 18.909

Answer:

-2

Step-by-step explanation:

If x=0

-3(0)+2y=-4

-0+2y=-4

We can say

2y-0=-4

2y=-4

Dividing both side by 2,

y=-2
