Answer:
u-shaped; y-intercept (0,6); symmetrical with respect to the y-axis
Step-by-step explanation:
Given that y = 2x² + 6
The graph would be the shape of that of a parabola. It can be u shaped or n shaped depending on the value of the coefficient of a comparing with the standard equation y = ax² + bx + c. If a > 0, it is u shape and if a < 0, it is n shape.
For this question, since a > 0 it would be u shaped and the intercept can be gotten by putting x = 0.
Therefore y = 0² + 6 = 0
The intercept is at (0,6) and is symmetrical with respect to the y-axis
Answer:
18:162
Step-by-step explanation:
1:9
1+9=10
(1×180)÷10= 18
(9×180)÷10=162
Hello wonderful person!!
Okay, so first of all, welcome to brainy
Second, you have to determine whether they are equal to each other and are the same. For example, if i say 2/4 is equal to 4/8, it's considered proportional.
Hope you understand this, and have a GREAT day!! :)
Answer:
20
Step-by-step explanation:
We are given the expression with two variables x and y and are asked to evaluate the expression 8x - y. We can complete this task by putting the values of x and y in that expression.
x = 2
y = -4
8x -y
= 8 (2) - (-4) //two negatives become positive
= 16 + 4 = 20
