Answer: (x,y) = (-1, 1)
This means that x = -1 and y = 1
========================================================
Explanation:
The first equation says that y is the same as 2x+3
That allows us to substitute y for 2x+3 in the second equation like so:
2x+5y = 3
2x+5( y ) = 3
2x + 5(2x+3) = 3 .... y replaced with 2x+3
2x+10x+15 = 3
12x+15 = 3
12x = 3-15
12x = -12
x = -12/12
x = -1
Then we'll substitute this into the first equation to find y
y = 2x+3
y = 2(-1) + 3 .... x replaced with -1
y = -2+3
y = 1
Together x = -1 and y = 1 pair up to form the ordered pair solution (x,y) = (-1,1)
If you were to graph y = 2x+3 and 2x+5y=3 on the same xy grid, then you should see that the two lines intersect at the location (-1,1). This is a visual way to determine the solution quickly through use of a graphing calculator.
p = unknown number
p ≥ -12 ["p" is any number greater than or equal to -12]
The only value that can make this true is 0, because all the other numbers are less than -12.
0 ≥ -12 [0 is greater than or equal to -12]
Answer:
I think the answer is ten
solve for x.
4x−5=7+4y
Add 5 to both sides.
4x−5+5=4y+7+5
4x=4y+12
Divide both sides by 4.
4x/4=4y+12/4
x=y+3

Answer:
258 ft²
Step-by-step explanation:
This shape is represented as a rectangle with dimensions of 18ft by 21 ft and a portion of it that has been cut out.
Let's find the area of the original rectangle:
Now let's find the area of the part cut out:
- 12 ft x (18ft - 8ft)
- 12 ft x 10ft
- 120 ft²
Subtract the part cut out from the original rectangle:
