Answer:
see below
Step-by-step explanation:
6 tens = 6 * 10 = 60
9 tens =
9* 10 = 90
12 tens=
12 * 10 = 120
10 elevens=10 * 11 = 110
It would be 150 miles
equation: y = 30x
Answer:
a) Upwards
b) x = -1
c) (-1,-9)
d) x intercepts; (2,0) and (-4,0)
y intercept is (0,-8)
Step-by-step explanation:
a) As we can see, the parabola faces upwards
b) To find the axis of symmetry equation, we look at the plot of the graph and see the point through the vertex of the parabola that exactly divides the parabola into two equal parts
The x-value that the line passes through here is the point x = -1 and that is the equation of the axis of symmetry
c) The vertex represents the lowest point of the circle here,
As we can see, this is the point through which the axis of symmetry passes through to make a symmetrical division of the parabola
We have the coordinates of this point as
(-1,-9)
d) The intercepts
The x-intercept are the two points in which the parabola crosses the x-axis
We have this point as 2 and -4
The x-intercepts are at the points (2,0) and (-4,0)
For the y-intercept; it is the y-coordinate of the point at which the parabola crosses the y-axis and this is the point (0,-8)
Answer:
x=8
Step-by-step explanation:
normally it would be 2x-1=
x+9 so now we have to combine the x into one fraction which will be 2x-1=
+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped
Answer: 1 is not a perfect square. 3 is the only prime number one less than a square.
