hope this helps
Answer:
x= 6 and y= -1
Step-by-step explanation:
-2x - 9y = -3
-7x - 9y = -33
I'm going to be solving by elimination. However, you can solve using substitution as well.
So the first step is to eliminate one of the variables. In my opinion, what's easiest is eliminating the y variables. To eliminate you want to variables (that are the same) to equal 0 and cancel out. To do this, all I have to do is subtract. When I subtract I get 0 as shown below. I will also subtract the other variables and numbers in the equations because that's how elimination works.
-2x - 9y = -3
-7x - 9y = -33
5x = 30
-2 - (-7)=5 and -3 - (-33)= 30
There's no solution for the y variable because -9 - (-9)=0, which cancels out so it doesn't have to be written.
after that you get x=6 because you divide by 5 on both sides.
All that's left is to plug in 6 to one of the equations:
-2(6) - 9y= -3
-12 - 9y= -3
+12 +12
-9y= 9
Divide both sides by -9 to get y= -1
Match the values with the statistical measures for these data points.

Juan has four ties, three shirts and four pairs of pants. How many different outfits can he wear if he chooses one Tie, one shirt, one pair of pants of each outfit?
Answer:
48 outfits
Step-by-step explanation:
Using Fundamental Principal of counting
number of outfits that Juan can wear
=number of ties * number of pants * numberof pants
=4*3*4
=48 outfits
The number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.
What is the combination?The arrangement of different things or numbers in a number of ways is called a combination.
A permutation is an orderly arrangement of things or numbers. Combinations are a way to choose items or numbers from a collection or group of items without worrying about the items' chronological order.
Given that Juan has four ties, three shirts, and four pairs of pants.
Using the Fundamental Principle of counting,
Number of outfits that Juan can wear
N =number of ties x number of pants x number of pants
N =4 x 3 x 4
N =48 outfits
Therefore, the number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.

What is the area of a parallelogram that has the length of 3.5cm and the height of 2.3cm?
What is the area of triangle BCD to the nearest tenth of a square centimeter? Use special right triangles to
help find the height. Show your work.
Answer:
Area = 13.8 cm²
Step-by-step explanation:
Area of a triangle = ½*base*height
base = 4 cm
height = ?
Find height using trigonometry function:
Reference angle = 60°
Opp = height = BC
Adj = 4 cm
Apply TOA:
Tan 60 = Opp/Adj
Tan 60 = BC/4
BC = 4*Tan 60
BC = 6.92820324 ≈ 6.9 cm
✔️Area of triangle = ½*4*6.9
= 13.8 cm²

A positive angle less than 360 that is coterminal with -725 degrees is
The positive angle is less than 360 which is coterminal with -725 degrees is 85 degrees.
What are Coterminal Angles?Coterminal angles are those with the same beginning side and the same terminal sides. These angles are in the typical position, although their values differ. They have the same sides, are in the same quadrant, and their vertices are identical. The endpoint sides coincide at the same angle when the angles are rotated clockwise or anticlockwise.
An angle that is coterminal with -725 degrees is an angle that has the same initial and terminal sides as -725 degrees, but its measure is between 0 and 360 degrees.
To determine a positive angle less than 360 that is coterminal with -725 degrees, we can add or subtract multiples of 360 from -725 degrees until we get an angle within that range.
In this case, -725 degrees - (2 x 360) = -725-720= -1445.
So, the positive angle less than 360 that is coterminal with -725 degrees is -1445 degrees + 360 = 85 degrees.

PLEASE SHOW WORK!!!
Due TODAY!!!!!
Answer:
x=-45/11
y=10/11
Step-by-step explanation:
y = x + 9 eq 1
3x + 8y = -5 eq 2
Re arranging eq 1
x-y=-9
Now multiply eq 1 with 8
8x-8y=-40 now call as eq 3
Add eq 2 and 3
3x+8y=-5
8x-8y=-40
11x=-45
x=-45/11
put value of x in eq 2 for y
3(-45/11)+8y=-5
-135/11+8y=-5
8y=-5+135/11
8y=(-55+135)/11
8y=80/11
y=(80/11)*(1/8)
y=10/11
Check
3*(-45/11)+8*(10/11)=-5
-135/11+80/11=-5
(-135+80)/11=-5
