Mathematics
1 answer:
Luda [366]3 years ago
5 0

Answer:

C) h(x)=-1.3-1.75x

Step-by-step explanation:

f(x)=3.7-2x  

g(x) = 0.25x-5

f(x) + g(x) =3.7-2x   + 0.25x-5

Combine like terms

              = -1.75x - 1.3

The correct options regarding the circle with endpoints of the longest chord at (4, 5.5) and (4, 10.5) are:

  • The center is (4,8).
  • The radius is of 2.5 units.
  • (x - 4)^2 + (y - 8)^2 = 6.25

<h3>What is the equation of a circle?</h3>

The equation of a circle of center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

The center is the <u>midpoint of the chords</u>, hence:

  • x_0 = \frac{4 + 4}{2} = 4.
  • y_0 = \frac{5.5 + 10.5}{2} = 8.

The radius is half the distance between the chords, hence:

r = 0.5\sqrt{(4-4)^2 + (10.5 - 5.5)^2} = 0.5 = 2.5.

Hence the equation is:

(x - x_0)^2 + (y - y_0)^2 = r^2

(x - 4)^2 + (y - 8)^2 = 2.5^2

(x - 4)^2 + (y - 8)^2 = 6.25

Using the slope formula, find the slope of the line through the given points.<br> (6,4) and (1,9)
hodyreva [135]

Answer:

-1

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(9 - 4) / (1 - 6)

5 / -5

= -1

So, the slope is -1

Jesse added two more numbers to his expression, but the sum did not change. What could the two new numbers be? Explain why the n
kenny6666 [7]

Answer:

0 and 0

Step-by-step explanation:

The only number that can be applied to the expression without changing the sum is 0, for example 5 + 10 = 15, adding 2 0's will be 0 + 5 + 10 + 0 = 15 :D
