Answer:
E
Step-by-step explanation:
Given
y = 2x² - kx + 3
with a = 2, b = - k and c = 3
Since the curve touches the x- axis at one place then the roots are real and equal and the discriminant for this condition is
b² - 4ac = 0, that is
(- k)² - (4 × 2 × 3) = 0
k² - 24 = 0 ( add 24 to both sides )
k² = 24 ( take the square root of both sides )
k = ± 
= ± 2
k = 2 or k = - 2 → E
Answer:The graph of F is shifted 3 to the left and 1 up
Step-by-step explanation:
On the x axis, negative is left, positive is right. On the y axis, negative goes down, positive goes up. X is negative, it goes to the left, and y is positive, it moves up. Hope this helps and good luck!
Slope = (9 + 3)/(-1 + 2) = 12/1 = 12
answer
12
Answer:
0.0425
Step-by-step explanation:
Since NS bisects QNR, the angles SNQ and SNR will be congruent.
They are congruent that means they are equal to each other. We will set them equal to each other and find the value of x first.
6x - 57 = 2x + 15
6x = 2x + 72
4x = 72
x = 18
Now we will substitute 18 for x in each angle measure and find measure of them.
Angle SNQ = 6(18) - 57 = 51
Angle SNR = 2(18) + 15 = 51
Now we will add both angles to find the total measure of angle QNR.
51 + 51 = QNR
102 = QNR
Hope this helps :)
