Answer:
No Solution
Step-by-step explanation:
Let us see the various conditions to check the number of solutions for a pair of linear equations.
Let our linear equations are
ax+by=c
px+qy=r
i) for Unique Solution
≠ 
= 
≠ ≠
ii) For No Solution
= ≠
iii) For many Solutions
≠ =
Let us see what ratio we have for our linear equation s
here
a=1 , b=-2 , c= 4
p=-3 , q = 6 , r = 12
= 
= - 
= 
= -
= 
=
- = - ≠
Hence it satisfies the second condition of No solution
Answer:
The values of y is -4 and 6
Step-by-step explanation:
Solve by factoring y^2 -2y=24
We need to factorize the term y^2 -2y=24.
Rearranging:
y^2 - 2y -24 =0
For factorizing we need to break the middle term such that their sum is equal to -2y and product is equal to -24y^2
We know, -6y*+4y = 24y^2 and -6y + 4y = -2y
y^2 -6y +4y -24 =0
y(y-6) +4(y-6) = 0
(y+4)(y-6)=0
Now, y+4 =0 and y-6 =0
Finding value of y,
y = -4 and y =6
So, the values of y is -4 and 6
(12,0) and (1250,0) only promblem is on the test since im doing it to there is no place to but (1250,0)
Answer:
a
Step-by-step explanation:
The answer is the second choice, or B; 240 ft^2.
You have to find the area of all four triangles and just add those all together.
Two of the triangles have an area of
5*16=80
Multiply that by two
80*2=160
The other two smaller triangles have an area of
8*5=40
Multiply that by 2 also
40*2=80
Add 160+80 and the answer is 240.
