Hey!

Your answer is in fact correct! When graphing the equation the y - intercept is about ( 2, 0 ) and the x - intercept is ( 0, -15 ). The line does in fact cross the point that is ( 3, 6 ).

Hope this helps!

Replace x with 3 and y with 6 and see which equation is true.

A) y = 7x - 15

6 = 7(3) - 15

6 = 21 - 15

6 = 6

The point (3, 6) makes the first equation true, so the answer is A). Point (3, 6) does not make any other choice a true equation. Answer is definitely A).

Good job!

Let Bea = x
Therefore Andrew = x + 2
Chris = x - 3

Andrew * Chris = 66
(x + 2)(x - 3) = 66 Remove the brackets.
x^2 + 2x - 3x - 6 = 66
x^2 - x - 6 = 66 Subtract 66 from both sides.
x^2 - x - 72 = 0
(x - 9)(x + 8) = 0
Find the possible values of Bea's age

x - 9 = 0
x = 9 That value works. She can be plus 9 years old.

x + 8 = 0
x = - 8. There's no way she can be - 8 years old

So Bea is 9.

17 Q Graph the inequality n a coordinate plane

aliina [53]

The resultant graph is shown in the attached image.

Explanation:
Before we begin, remember that when we multiply by a negative sign, we flip the sign of the inequality
The given inequality is:
-y ≤ 3x - 5
We will multiply both sides by -1 to get a positive y vale. This will give us:
y ≥ -3x + 5

Now, to graph the inequality, we will first draw the line y = -3x + 5 and then shade the region having y values greater than the line.
To know the region, you will simply use trial and error method for random points on the two sides of the line.

The final solution would be as shown in that attachment.

Hope this helps :)
