ANSWER:D

Explained:
When in form y=mx+c , the c is the y intercept

Y^2=-x^2 +64
Y=-x + 8

For circle to cut x axis y must = 0
So Y=-x+8 becomes...
0=-x+8 |minus 8 from both sides
-8=-x
So x=8

Anestetic [448]

Answer:

a. -3 < x ≤ 5

b. -3 ≤ y < 3

c.  (0, 0)

d. x = -3, x = 1, x = 5

e. -3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. (-1, -1), and (3, -3)

Step-by-step explanation:

a. The domain of a function is the set of the possible independent variable values which is -3 < x ≤ 5

b. The range of a function is the set of the possible values of the dependent variable which is -3 ≤ y < 3

c. The y-intercept is the point the graph crosses the y-axis

The y-intercept in the graph is the point (0, 0)

d. f(x) ≥ 0  when x = -3, x = 1, x = 5

f(x) ≥ 0 over the following range; -3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5

e. The intervals over which f(x) is decreasing are;

-3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. The local minimums where f(x) has the minimum values are;

(-1, -1), and (3, -3)

144kg in the ratio of 9:8:7​
ANEK [815]

Step-by-step explanation:

Hey there!

Given;

Ratio = 9:8:7

Let "x" be the common factor. So,

9x+8x+7x = 144

or, 24x = 144

or, x = 144/24

or, x= 6

It's like;

= 9*6:8*6:7*6

= 54:48:42

Therefore, their ratio is 54:48:42.
