Answer : x = 20
Explanation :
3x + 2x +20 + 4x - 20 = 180
(3+2+4=9)
9x + 20 - 20
The 20s cancel each other out because one is positive and the other is negative
9x = 180
9x/9 = 180/9
X = 180 divided by 9
X = 20
Answer:
-4
Step-by-step explanation:
y=-4x-9
y=mx+b
m=slope
Answer:
downwards
Step-by-step explanation:
the equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
• if a > 0 then parabola opens upwards
• if a < 0 then parabola opens downwards
for
f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then
the parabola opens downwards
Answer:
24x^7 = 24x^7
Step-by-step explanation:
Left side of equation: 3 times 8 times X = 24x
Then you raise it to the 7th power
Right side of the equation: 6 times 4 times X = 24x
Since the exponent is the same, you keep it as the 7th power
