x+3y=0 and 12y=-4 equation plz help.
Answers
Answer:
[tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]
Step-by-step explanation:
So we can equate the second equation in terms of y by dividing both sides by 12:
[tex]y = -\frac{1}{3}[/tex]
Let us substitute this into the first equation:
[tex]x + 3y = 0[/tex]
then becomes
[tex]x + 3(-\frac{1}{3} ) = 0[/tex]
which simplifies to
[tex]x - 1 = 0[/tex]
Finally solving for x gives us:
[tex]x = 1[/tex]
Therefore, [tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]
Hope this helps!

During batting practice, Lenora hit 60% of the 20 pitches that were thrown to her. What fraction of the pitches thrown did Lenora hit?
Answers
Answer:
A 3/5
Step-by-step explanation:Here’s one way to solve this problem.
Write sixty percent as a fraction having a denominator of one hundred.
Now, change sixty-hundredths to an equivalent fraction having a denominator of twenty, the total number of pitches.
Do this by dividing the numerator and the denominator by five.
Then, simplify the fraction twelve-twentieths by dividing the numerator and the denominator by four.
So, Lenora hit three-fifths of the pitches.

and Sal is 175ft, what is the angle of Sonny's line of sight to both Sam and Sal to the
nearest whole degree?
a. 25°
b. 75°
c. 57°
d. 123°
Answers
Answer:
Step-by-step explanation:
Answer:
b. 75°
Step-by-step explanation:
Draw a triangle. Write a person name and a point name (a letter) at each vertex: Sam A, Sonny B, and Sal C at the vertices.
Write the distances as AB = c = 153 ft; AC = b = 201 ft; BC = a = 175 ft.
We are looking for angle B.
Since we have a triangle with three side lengths and no angle measures, we use the Law of Cosines.
[tex] b^2 = a^2 + c^2 - 2ac \cos B [/tex]
[tex] 201^2 = 175^2 + 153^2 - 2(175)(153) \cos B [/tex]
[tex] 40401 = 30635 + 23409 - 53550 \cos B [/tex]
[tex] -53550 \cos B = -13643 [/tex]
[tex] \cos B = \dfrac{-13643}{-53550} [/tex]
[tex] \cos B = 0.254771242 [/tex]
[tex] B = \cos^{-1} 0.254771242 [/tex]
[tex] B = 75^\circ [/tex]

Answer:
AB = 17 m, AC ≈ 19.2 m
Step-by-step explanation:
Drawing a line from A to the base creates a right triangle
with legs 8 and (25 - 10 ) = 15
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² = 15² + 8² = 225 + 64 = 289 ( take the square root of both sides )
AB = [tex]\sqrt{289}[/tex] = 17 m
------------------------------------
Using Pythagoras' identity i right triangle ABC
AC² = AB² + BC² = 17² + 9² = 289 + 81 = 370 ( take square root of both sides )
AC = [tex]\sqrt{370}[/tex] ≈ 19.2 m ( to 1 dec. place )

What is the range?A function's range is the whole set of potential values that it can have. When we insert an x value into the function, the range is the collection of values that results. Range refers to the y values.
Given a figure in which the function is not differentiable since the graph is broken at (-2, 3) and (2, 4). Since at Y = 3 there is no point in the graph. therefore Y = 3 is not in the range of the function.
