The descending numbers are as follows : 5.4>5.34>-1.8>-3.216>-3.62
Answer:
A.
Step-by-step explanation:
A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.
Choice B contradicts the previous statement.
Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.
Choice D is wrong because the y-intercept is where x = 0.
I hope this helps!
Answer:
see below
Step-by-step explanation:
do long division
for example 42/8 = 5 2/8 =5 1/4 =5.25
2x + y = 4
2x - y = 8
-------------add
4x = 12
x = 12/4
x = 3
2x + y = 4
2(3) + y = 4
6 + y = 4
y = 4 - 6
y = -2
okay....so x = 3 and y = -2
3x - y = ?
3(3) - (-2) = ?
9 + 2 = 11....so ur answer is 11
