Answer:
there's no solution.
Step-by-step explanation:
if y = 3x -4 then use this instead of y in the second equation
9x -3(3x+4) = 14 ➡9x-9x -12 = 14 9x will eliminate -9x and -12 can't be = 14 so there's no solution

Answer:
25π/4 square meters
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius of the circle.
The radius is half the diameter, so is (1/2)(5 m) = 5/2 m. Using this in the area formula, we find the area to be ...
A = π(5/2 m)² = (25/4)π m²
The area of the circle is 25π/4 square meters.
__
As a decimal, that is 6.25π square meters.
Find 33% of 185:
0.33 * 185 = 61.05
Subtract this from the regular price:
185 - 61.05 = 123.95
So the sale price is $123.95
Answer:
ABC is not a right triangle
Step-by-step explanation:
The computation is shown below:
AC is
= Perimeter - (AB + BC)
= 22 - (8+5)
= 22 - 13
= 9
Now
= 9^2 + 13^2
= 81 +169
= 250
And, the perimeter is
= 22^2
= 484
Since the amount are not equivalent therefore ABC is not a right triangle
