Answer:
P and Q are two points on the line x-y+1=0 and are at the distance 5 units from origin. Find the area of the triangle OPQ. P and Q are two points on the line x-y+1=0 and are at the distance 5 units from origin. ... The area of PQR is 7*7/2 = 49/2 sq units.
Answer:
(-1, 5)
Step-by-step explanation:
Rearrange the the first equation to have y on one side and all other values on the other side
y = 1 - 4x
since both of the equations are equal to y, set them equal to each other an solve for x.
1 - 4 x = x + 6
-5 = 5 x
x = -1
plug this back into the second equation to get y = 5
the answer is a because the +2 is the why intercept.
2z−31=−9z+24
Add 9z to both sides.
2z−31+9z=−9z+24+9z
11z−31=24
Add 31 to both sides.
11z−31+31=24+31
11z=55
Divide both sides by 11.
11z/11=55/11
z=5
- A rectangular patio has a length that is 4 times its width.
- Area of rectangular patio is 5000 square feet.
Calculate the width of the patio.
Let the width be a.
Then,Length = 4a
<u>According</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>question</u><u>, </u>
<u>
</u>
Substituting the values of Length and width, we get..
