Answer:
0
Step-by-step explanation:
-4, -2, 0
the 3rd number is always a 0 so if you do the sequence 78 times the 78th term will be a 0
Answer:
True, false, true, true.
Step-by-step explanation:
The roots zeros of a quadratic function are the same as the factors of the quadratic function. This is true because your roots are your factors—>(x-3) is a factor, x=3 is the root.
The roots zeros are the spots where the quadratic function intersects with the y-axis. No! Those are called y-intercepts!
The roots zeros are the spots where the quadratic function intersects with the x-axis. True. X-intercepts are your solutions. (x-3) graphed would the (3,0). That’s a solution.
There are not always two roots/zeros of a quadratic function, True. No solution would be when your quadratic doesn’t intersect the x-axis. One solution would be when your vertex would be on the x-axis. Two solutions is when your quadratic intersects the x-axis twice. Can there be infinite solutions? No. It’s either 0, 1, or 2 solutions.
Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>
Answer:
30
Step-by-step explanation:
10×7/10=21×10
7÷7=210÷7
answer=30
Step-by-step explanation:
I'll help you darling
a. B
b. 2.6 + x = 10.4
c. x = 10.4 - 2.6
= 7.8
d. This is to say before mia added the 2.6 litres of what the pitcher contained 7.8 litres of water already
