POQ AND KLJ
They are the only alternate exterior angles
Answer:
(1,4)
Step-by-step explanation:
The two lines intersect at 1,4 when you graph them
The first equation is already in slope intercept from, so you know the y-int. is 7 and the slope is 3. However, the second equation must be put in slope int. form.
5x+2y=3
move the y to the other side
5x=3-2y
move the 3 to the other side, so the y variable is by itself
5x-3=-2y
divide by -2 to the equation is equal to y
(-5x/2)+(3/2)=y
you now know the y int. of the second equation is 3/2 and the slope is -5/2
know that you know the slop int. formulas for both equations you can graph them
A rectangular garden has a length of 5ft and a width of 8 ft. The length is increased by 2 feet. By how many square feet does the area increase?
Step 1. Area of a rectangle is given as A=length * width
Step 2. Then, A1=5*8=40 square feet of original area of rectangular garden.
Step 3. Then, A2=(5+2)*8=56 square feet since the length is increased by 2. feet.
Step 4. Difference = A2 - A1 = 56 - 40 = 16 square feet.
Step 5. ANSWER: The area increased by 16 square feet.
-- The x-intercept is the point where the line crosses the x-axis.
So y=0 there.
<u>-2x - 4y = 8</u>
-2x - 4(0) = 8
-2x = 8
Divide each side by -2 : x = -4 => the x-intercept is (-4, 0)
-- The y-intercept is the point where the line crosses the y-axis.
So x=0 there.
<u>-2x - 4y = 8</u>
-2(0) - 4y = 8
-4y = 8
Divide each side by -4 : y = -2 => the y-intercept is (0, -2)
Now you have two points on the graph ... the points where the line crosses each axis.
Mark little dots at both points, then lay your ruler across both dots, and draw
the line along the edge of the ruler, as far as you want to in both directions.
