Answer:
the answer is (x,y) = (6,6)
Step-by-step explanation:
1) first solve the equation for 2y
you should've gotten:
2y = -6 + 3x
5x - 2y = 18
2) substitute the value of 2y into the equation
5x - 2y = 18
so, 5x -(-6 + 3x) = 18
3) now solve 5x -(-6 + 3x) = 18
4) from that solving that equation, u should've gotten x = 6
5) now plug in 6 for x in the other equation, solve for y
( • stands for multiplication if u didn't know, we use this in higher levels of math so multiplication symbols and x variables aren't confused)
5 • 6 - 2y = 18
6) after solving for y in the previous equation, u should've gotten y = 6
7) now we know that x = 6 and y = 6, however it is always important to check if ur answer is correct by plugging in the x value y values u ended up with into the original system of equations.
checking ur work would look something like this:
2(6) = -6 + 3(6)
5(6) - 2(6) = 18
hope this helps <3

How do you write 3,390 in scientific notation?
x 10
Answer:
3.39 × [tex]10^{3}[/tex]
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. Since the decimal is going right, the exponent will be positive

Does the equation represent a linear or nonlinear function? Explain.
y = x + 5
Answer:
Below.
Step-by-step explanation:
A linear function contains a variable of the first degree only - for example f(x) = 2x - 1 or f(z) = 3z.
So y = x + 5 is linear.

PLEASE HELPPPP!!! Find the measure of angle A
========================================================
Explanation:
The three angles of this triangle are
20x9026x-2The square angle marker represents 90 degrees. It's also referred to as "a right angle".
As a rule, the three angles of any triangle always add to 180. Let's use this fact to solve for x
(angle1)+(angle2)+(angle3) = 180
(20x)+(90)+(26x-2) = 180
(20x+26x) + (90-2) = 180
46x+88 = 180
46x = 180 - 88 .... subtract 88 from both sides
46x = 92
x = 92/46 ........ divide both sides by 46
x = 2
Now that we know what x is, we can find angle A
angle A = 20x = 20*2 = 40 degrees
-------------
As extra info, we could also find the other angle with this x value
26x - 2 = 26*2 - 2 = 52 - 2 = 50 degrees
The three angles of the triangle are: 40, 50, 90 which add to 40+50+90 = 180. This helps confirm our answer.

23. Describe the slopes of perpendicular lines
Answer:
The slopes of two perpendicular lines are negative reciprocals of each other. This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2.
The slopes of perpendicular lines when multiplied together gives the product as -1.
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
Suppose the two perpendicular lines have equations as follows,
y = m₁x + c₁ and y = m₂x + c₂.
Suppose m₁ = tan θ
Then, m₂ = tan (90° + θ)
Apply the trigonometric identity to obtain,
m₂ = tan (90° + θ) = -cot θ
Now, m₁ × m₂ = tan θ × -cot θ = -1
Thus, the products of slopes is -1.
Hence, the product of slopes of two perpendicular lines is -1.

One hundred forty-four of the 180 seventh-grade students attended the school dance last Saturday night. What percentage of seventh-grade students did NOT attend the dance?
Answer:
20%
Step-by-step explanation:
Because 144 OUT OF the 180 seventh grade students attended, this would represent 144/180.
But since we are trying to solve how many did NOT attend the dance, you must subtract 144 from 180 which equals 36. So 36/180 did not attend the dance.
But to make it a percentage, you divide 36/180. Fraction and percentage are like buddies! That's why it is very simple to make a fraction into a percentage.
36/180 can be simplified to 1/5, which as a decimal, is 0.20.
0.20 is same as 20%, so this should be the students that did not attend the dance.
I hope this helps. If this is wrong, I truly apologize...
