Answer:

x=4 y=0

Step-by-step explanation:

3x+5y=12

-(x-3y=4)

3x+5y=12

3(-x+3y=-4)

3x+5y=12

-3x+9y=-12

14y=0

y=0

Then, substitute the y into the equation to find x

x-3(0)=4

x=4

Challenge A bag contains pennies, nickels dimes, and quarters. There are 50 coins in all of the
vova2212 [387]

Answer:

The bag contains $5.14

Step-by-step explanation:

18% of 50 = (.18)(50) = 9 pennies

40% of 50 = (.40)(50) = 20 dimes

2 more nickels than pennies = 9 + 2 = 11 nickels

40 coins so far, so 50 - 40 = 10 quarters

Total value:

9 x ($0.01) = $0.09  for pennies

20 x ($0.10) = $2.00 for dimes

11 x ($0.05) = $0.55 for nickels

10 x ($0.25) = $2.50 for quarters

Grand total value = $5.14

Line segment st is dilated to create line segment s't' using the dilation rule dq,2.25. point q is the center of dilation. line
astra-53 [7]

The value of x when the line segment st is dilated to create line s't' about point q is 2.5 units

<h3>How to determine the value of x?</h3>

The given parameters are:

qs = 2

qt = 1.2

tt' = 1.5

ss' = x

To calculate the value of x, we make use of the following equivalent ratio

ss' : qs = tt' : qt

So, we have:

x : 2 = 1.5 : 1.2

Express as fractions

x/2 = 1.5/1.2

Multiply both sides by 2

x = 2 * 1.5/1.2

Evaluate the product

x = 2.5

Hence, the value of x is 2.5 units

Identify an equation in point-slope form for the line parallel to y = -
inessss [21]
It wouldn’t be any of those- because its in point-slope form ( y-y1=m(x-x1) ) the slope is -2/3, then the -5 (y) turns to +5 because there’s 2 negatives- since the x is positive it stays subtraction

The Correct equation would be y+5=-2/3(x-4)

Hope that helps :)
