Hello!

We can solve this by using substitution

we can plug y = x - 1 into the other equation

So 2x - 3( x - 1) = -1

We can distribute the -3 to (x - 1)

2x - 3x + 3 = -1

Combine like terms

-x + 3 = -1

Subtract 3 from both sides

-x = -4

Since x is negative we can multiply both sides by -1

x = 4

We can plug x into the first equation

y = (4) - 1

y = 3

The answers are x = 4 and y = 3

Hope this helps!

2x-3(x-1)=-1. (Plug in equation for y into the first equation). 2x-3x+3=-1. -x=-4. x=4. y=x-1 y=4-1. Y=3. X=4.

The difference of two numbers is 40. Their sum is 66. Find the numbers.
Margaret [11]
First of all, x>y
x-y=40
and
x+y=66
add them equations together to eliminate

x-y=40
<u>x+y=66 +</u>
2x+0y=106

2x=106
divide by 2
x=53

sub back
x-y=40
53-y=40
minus 53 both sides
-y=-13
y=13


the numbers are 53 and 13

Ilya [14]
Hey there!


840 = 100%

x = 17%

840/x = 100%/17%

(840/x) * x = (100/17) * x 840 = <span>5.8823529411765
</span>
<span>= 840/5.8823529411765 = 142.80

The correct answer to your question is option C.

The tip Christian should leave is $142.80.

Hope this helps you.

A circle has a center of (5,-5) and goes through (6,-2). What is the radius?
azamat
Let O(5, -5) be the center of the circle, and P(6, -2) be a point on this circle.

The distance between points O and P, that is |OP|, is the radius of this circle, 

We use the distance between 2 points formula:

|OP|=\sqrt{ (x_2-x_1)^{2} + (y_2-y_1)^{2} }=  \sqrt{ (6-5)^{2} + (-2-(-5))^{2} }
= \sqrt{ 1^{2}+ (-2+5)^{2}} = \sqrt{1+9}= \sqrt{10} (units)

Answer: \sqrt{10} units
