Option 4 is correct
The relationship is:
y = 3/4 x
Solve this system of equations with matrices. x – 5y – 4z = 15 -3x +2y + 3z = -6 4x + 8y – 2z = 3
Answer:
x = 59/10, z = 237/70, and y = -121/70
Step-by-step explanation:
In XYZ, what is the cosine ratio of X?
Answer:
c) 12/15 = 4/5
Step-by-step explanation:
imagine we mirror the triangle up, so that Z is on top.
then you can clearly see that 6 is cos(X) times r (and r is then 7.5).
XY is sin(X)×7.5
and again, 7.5 is r (the line making the X angle).
so, the cosine ratio of X is
6 = cos(X)×7.5
cos(X) = 6/7.5 or then 12/15. or simplified 4/5.

Write the equation of the line in slope-intercept form with a slope of 5/6 and passes through the point (0, -6).
Answer:
y=(5/6)x-6
Step-by-step explanation:
The slope intercept form of a line is y=mx+c. The equation of the line will be y=(5/6)x-6

What is 8j - 3k + 6 - 7j + 3k - 4 simplified
Answer:
j+2
Step-by-step explanation:
combine like terms
3k - 3k = 0
8j - 7j = 1j or j
6 - 4 = 2
put it all together
j + 2
Answer:
j + 2
Step-by-step explanation:
= 8j - 3k + 6 - 7j + 3k - 4
= 8j - 7j - 3k + 3k + 6 - 4
=j + 2

what’s the answer for the first question? pls help i don’t have much time…
Answer and Step-by-step explanation:
1.
Since we known how much money Jane and Mark have in total, we can subtract the amount Jane has to find the amount Mark has.
750 - 175 = $575
Mark has $575.
2.
We know how many cards Jamal sold, so if we add it to the amount he still has left, we can find the original amount of cards Jamal had.
17 + 83 = 100
Jamal had 100 cards.
#teamtrees #PAW (Plant And Water)
Answer:
Mark will have $575.
Step-by-step explanation:
Take the total amount ($750) and subtract Jane's contribution ($175) to get Mark's contribution($575).
$750-$175=$575

A textbook store sold a combined total of 331 physics and sociology textbooks in a week. The number of sociology textbooks sold was 45 less than the number
of physics textbooks sold. How many textbooks of each type were sold?
Answer: Number of sociology books sold = 143 books
Number of physics books sold = 143 + 45 = 188 books
Step-by-step explanation:
Let us take the number of sociology books sold = x
Number of physics books sold = x+45
So now we can form an equation
x+x+45 = 331
2x+45 = 331
2x = 331-45
2x = 286
x = 286 ÷ 2
x = 143

FIND THE AREA OF THE SHADED REGION.
This problem can be a bit confusing, so let's break it down:
First, let's take the area of the square (A = b · h):
A = 15 · 15
A = 225 cm²
Now comes the confusing part:
We can tell that the non-shaded area is 1/4 of a circle, so, if we take 1/4 of the area of a circle, we can subtract its area from the area of the square:
A = πr²
A = 15²π
A = 225π
1/4 A = 225π / 4
New Area = 56.25π
Or... about 176.7
Since we have both of the areas, all we have to do is subtract:
225 - 176.7 =
48.3.
Your final answer is 48.3 cm²

I hope this helped! :)Solve for y, given that b=22(Round your answer to 1 decimal place, if necessary.)
Answer:
37.7
Step-by-step explanation:
First, we have to divde 22/7 to find the scale factor. I chose 22 and 7 because those two sides are ocngruent. We get 3.14. We then have to multiply 12 by 3.14 beacuse that is the side that is congruent with the side y. When you multiply you should get 37.68. Since we have to round we get 37.7.

solve for the measure of a
Answer:
Step-by-step explanation:
The supplement of the exterior angle is 180 - 75 = 105
In a cyclic quadrilateral (a four sides figure where all the vertices touch the circumference of a circle), the opposite angles are supplementary. Therefore <a = 180 - 105 = 75
But I think you already knew that.

Vanessa and her friends are watching three movies consecutively. The first movie is 2 hours and 17 minutes long. The second movie is 84 minutes long, and the last movie is 99 minutes long. How much time will they spend watching the movies?
Answer:
320 minutes (5 hours and 20 minutes).
Step-by-step explanation:
2 hours and 17 minutes = 137 minutes
137 + 84 + 99 = 320
Therefore, they will spend 320 minutes (5 hours and 20 minutes) watching movies.

Option ( B) is the correct answer
In the figure below j ll h find the values of x and y
Answer:
26
Step-by-step explanation:
Given: Lines J and H are parallel lines. O intersects both lines equally.
Since two angles equal 180, that will be what (4y + 12) and 64 will be equal to.
(4y + 12) + 64 = 180
76 + 4y = 180
-76 -76
-------------------
4y = 104
y = 26
x and y is both 26 because they are vertical angles.
