Answer:
A. -3/2
Step-by-step explanation:
» Concepts
The slope of a line describes the steepness, or the change in y over the change in x of a line. The formula to find the slope, given two points, is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where we put in the x- and y-coordinates of the two points.
» Application
In this case, we're given two points: (-2, 5) and (4, -4). We have to find the slope of the line containing them, so we must use our aforementioned formula.
» Solution
[tex]\frac{(-4)-(5)}{(4)-(-2)}[/tex] [tex]\frac{-9}{4+2}[/tex] [tex]-\frac{9}{6}[/tex] [tex]-3/2[/tex]Therefore, the answer is A. -3/2.

What is the exact value of the other root?
Answers
The exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]
How to express the solution?One of the root is given as:
[tex]x = -2 - \sqrt 6[/tex]
As a general rule, the solution to a quadratic equation is represented by:
[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
This means that the actual root of the given root is:
[tex]x = -2 \pm \sqrt 6[/tex]
Split the equation
[tex]x = -2 - \sqrt 6[/tex] and [tex]x = -2 + \sqrt 6[/tex]
Hence, the exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]

D. 16
Answers
Answer: 12.5
Step-by-step explanation:
12.5 is the length of BC.
Here, we have,
given that,
In the diagram shown below, AC is tangent to circle o at A and to circle Pat C, OP intersects AC at B, OA = 5, AB = 5, and PC = 10.
now, we know that,
∠OAB and ∠BCP are right angles, because of the tangents.
and, ∠OBA ≅ ∠CBP (vertical angles)
thus, we get,
ΔAOB ≅ ΔCBP, by AA rule.
so, we can set up the proportion:
10/4 = x/5
or, x = 12.5
Hence, 12.5 is the length of BC.

A. 3/2
B. 7/3
C. 9/2
D. 5/3
Answers
Answer:
look at the explanation
Step-by-step explanation:
In order to solve this, we'll set up a proportion.
Since y is inversely related to the square of x, therefore:
y=4/63 ----->9 (square of x)
y=?
25 (square of x)
According to the inverse relation:
y=4/63------->25
y=? --------
-->9 and y=4/175

Step-by-step explanation:
QuestionSolve the system of linear equations:
8x = 93 + 11y7x = -63 - 11y-------------------------------------------------------------------------------------
SolutionAdd the equations together to eliminate y:
8x = 93 + 11y
+ 7x = -63 - 11y
-------------------
15x = 30
⇒ x = 30 ÷ 15
⇒ x = 2
Now substitute the found value of x into one of the equations and solve for y:
⇒ 7x = -63 - 11y
⇒ 7(2) = -63 - 11y
⇒ 14 = -63 - 11y
⇒ 11y = -63 - 14
⇒ 11y = -77
⇒ y = -77 ÷ 11
⇒ y = -7
Therefore, x = 2 and y = -7

Suppose you write the numbers 1 to 10 on separate index cards. You randomly choose one card, place it back in the set, and then randomly choose another card. What is the probability that the first card you choose is the number 1 or the second card you choose is the number 2?.
Answers
Answer:
1/100
Step-by-step explanation:
From 1 to 10 there are 10 numbers, so the fraction would be:
# / 10
Since you are putting the cards back into the deck, the denominator will never change.
The chances of getting " 1 " are 1 / 10.
And the chances of getting " 2 " are also 1 / 10
To find the odds of getting one-after-the-other, you multiply these 2 chances.
( 1 / 10 ) x ( 1 / 10 ) = ( 1 / 100 )
There is a 1 / 100 chance that you will draw 1, then 2 if you put the cards back after drawing.

Answers
The probability that Mary's outfit will be black blouse, black pants, black shoes is 1/24 if the Mary has 3 blouses, 2 pairs of pants, and 4 pairs of shoes.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
We have:
Mary has 3 blouses (red, black, and white), 2 pairs of pants (black and blue), and 4 pairs of shoes (red, blue, black, and white).
P(black blouse) = 1/3
P(black pants) = 1/2
P(black shoes) = 1/4
Probability that Mary's outfit will be black blouse, black pants, black shoes:
= (1/3)(1/2)(1/4)
= 1/24
Thus, the probability that Mary's outfit will be black blouse, black pants, black shoes is 1/24 if the Mary has 3 blouses, 2 pairs of pants, and 4 pairs of shoes.

Answers
The angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.
What is the coterminal or terminal side of an angle?The terminal side of an angle is the rotated side of the initial side around a point to form an angle. This rotation can be clockwise or counter clock wise.
The angle given in the problem is,
θ=125°
The angle which is coterminal of this angle is,
θ=125°-360°
