1 answer:
astraxan [27]2 years ago
6 0

Answer:

Not possible, but if there are any answer choices please add them in the comments below.

Step-by-step explanation:

In order for you to get 45 questions correct you wouldn't have enough questions on the test to do so, because as you've stated there are only 20 questions on the test, so you would need to complete more than one test.

If this is the case then you would need to complete 3 tests of 20 questions. and get 15 questions right on each test to get 45 questions correct in total.

Hope this has helped, have a good day.

The circle below is centered at the point (4,3) and has a radius of length 5.
Lilit [14]

Answer:

B. (x-4)^2 + (y - 3)^2 = 5^2

Step-by-step explanation:

The equation for a circle is given by

(x-h)^2 + (y-k) ^2 = r^2

where (h,k) is the center and r is the radius

We have a center of (4,3) and a radius of 5

(x-4)^2 + (y-3) ^2 = 5^2

Please help i suck at these
vaieri [72.5K]

Answer:

1st Option;

j = 4.5

k = 2

Step-by-step explanation:

Let's solve for "j" first:

=> We know that by the definition of midpoint segment theorem we can say;

3j = 5j - 9

0 = 5j - 3j - 9

0 = 2j - 9

0 + 9 = 2j

9 = 2j

9/2 = j

4.5 = j

=> Now that we have j-value we use the same method to solve for k-value;

6k = k + 10

6k - k = 10

5k = 10

k = 10/5

k = 2

Therefore;

j = 4.5

k = 2

<u>So the first option would be correct!</u>

Hope this helps!

1. Write an equation in point-slope form for the line through the given point with the given slope.
ElenaW [278]

Answer: y + 2 = \frac{-1}{2} ( x - 4 )

Step-by-step explanation:

The equation of a line in point - slope form is given as ;

y - y_{1} = m (x -  x_{1})

x_{1} = 4

y_{1} = -2

m = \frac{-1}{2}

Substitute the values into the equation , we have

y - (-2) = \frac{-1}{2}( x - 4 )

y + 2 = \frac{-1}{2} ( x - 4 )

Which could be written as :

y + 2 = y + 2 = \frac{-1}{2} x + 2
