Answer:
Yez
Step-by-step explanation:
Yes
Answer:
C
Step-by-step explanation:
4x+3y=-24
eq. of any line perpendicular to given line is
3x-4y=a
4y=3x-a
y=3/4x -a/4
where a is an arbitrary constant.
A.) We know, sum of the complimentary angles is equal to 90.
So, Equation: 15 + x = 90
B.) Solving: 15 + x = 90
x = 90 - 15
x = 75
In short, Your Answer would be 75
Hope this helps!
Answer:
Step-by-step explanation:
y=-3x²-4x+7...(*)
3x+2y=18...(**)
use (*) put the value of y in (**) :
3x +2(-3x²-4x+7)=18
3x-6x²-8x +14 -18 = 0
-6x²-5x- 4 = 0
6x²+5x+4 = 0
delta = b² - 4ac a = 6 b=5 c =4
delta = 5² - 4(6)(4)= 25 -96= -71 negatif
so no reals solution
4.5 (4-x)+36=202-2.5(3x+28)
45 (4-x)+360=2020-25(3x+28)
-45x+540=-75x+1320
-45x+540-540=-75x+1320-540
-45x=-75x+780
-45x+75x=-75x+780+75x
30x=780
30x/30= 780/30
x=26 the anser
