Answer: B. One solution
Step-by-step explanation: As you see, both of these lines intersect on the point (0, 3). The point where the lines intersect is the solution. Since these lines are perpendicular, they will only intersect one time. Therefore, there is only one solution, that being (0, 3).

Answer:
x = 29/8c
Step-by-step explanation:
2/3(cx+1/2) - 1/4+ 1/4 = 5/2+1/4
2/3(cx+1/2) = 11/4
1/3(cx+1/2) = 11/4 / 2
cx/3 + 1/2/3 = 11/4/2
cx/3 + 1/2*3 = 11/4/2
cx/3 + 1/6 = 11/4/2
cx/3 + 1/6 = 11/4*2
cx/3 + 1/6 = 11/8
cx/3 = 11/8 - 1/6
cx/3 = 29/24
cx = 29/24 * 3
x = 29/8 / c
x = 29/8c
Answer:
Step-by-step explanation:
(-3x + 2)(45x + 21) + (-4x + 25) = 50
-135x^2 - 63x + 90x + 42 - 4x + 25 = 50
-135x^2 + 23x + 67 = 50
-135x^2 + 23x + 67 - 50 = 0
-135x^2 + 23x + 17 = 0
quadratic formula : x = (-b ± √b^2 - 4ac)/2a
a = -135, b = 23, c = 17
x = -23 ± √23^2 - 4(-135)(17) / (2(-135)
x = (-23 ±√9709 )/ -270
x = 23/270 ± 1 / 270√9709/270
x = 0.4501 or x = - 0.2798 <=== these answers are rounded
Hello! :)
Let's use PEMDAS.

(5-2) = 3 Do parenthesis.
7 × 3 = 21 Multiply with what we got after doing the parenthesis.
9 + 21 = 30 Add with what we had left.
30
