Step-by-step explanation:
-5x + 4y = 2
+ (9x - 4y = 6)
=> 4x = 8, x = 2.
Therefore -5(2) + 4y = 2, 4y = 12, y = 3.
The solution pair is (2,3).
4(x)squared+3x+3=6(x)squared-4x=6 find x
Answer:
I think if yo seperate 4 from x then seperate 3 from x add those together and you get 18.

39,000 over 12 = ?? Also, show your work so I can do the rest of these myself
Answer:
3,250
Step-by-step explanation:
Let's go from left to right, using multiple of 12 times a power of 10 in the process.
What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.
12,000 * 3 = 36000
39000 - 36000 = 3000
What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.
1,200 * 2 = 2,400
3,000 - 2,400 = 600
What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.
120 * 5 = 600
600 - 600 = 0.
The answer to 39,000 over 12 is 3,250.

Express in the form
n:1
.
Give n as a fully simplified fraction.
8:6
Answer:
4/3 : 1
Step-by-step explanation:
Here, we want to express 8:6 in the form n:1
All we have to do is to divide both ratio sides by 6
That would be;
8/6 : 6/6
= 4/3:1
Please help me answer this.

(-1/2 + 5/2) + a =0 solve for a
Answer:
a = -2
i hope this helps
Answer: a = - 2
Step-by-step explanation:
[tex]\bigg (-\dfrac{1}{2} +\dfrac{5}{2} \bigg )+ a=0\\\\ \dfrac{4}{2} +a=0\\\\2+a=0\\2+a-2=0-2\\a=-2[/tex]
How would you solve this?
Answer:
For the equation, you should subtract 2x on both sides to get -y = -2x - 4. Flip the y's negative sign to get a proper function which is y = 2x + 4. The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.

True or False:
a = 6 is a solution to the inequality a > 6
----
A) True
B
False
Answer:
False.
Step-by-step explanation:
If we substitute a for 6, the inequality would become 6 > 6. That is not true because 6 cannot be greater than itself.

A triangle has sides with lengths of 3 yards, 4 yards, and 5 yards. Is it a right triangle?
Answer:
It is a right triangle
Step-by-step explanation:
Depending on how you make the triangle if 3 is A 4 is B and 5 is C then the Pythagorean Theorm would be correct and it would be a right triangle.

Answer:
m = 1 and b = 5/7
Step-by-step explanation:
Take two of the points. The first two. (7, 5) and (8, 6).
We can find the slope using:
y2-y1/x2-x1
We can sub in the values:
6-5/8-7 = 1/1 = 1
So the slope is 1
now, putting this into y=mx+b, and using one of the coordinates from earlier, we can solve for b:
5 = (1)(7) + b
b = 5/7
Therefore, m = 1 and b = 5/7
Hope this helps!

Dr. Hammer noticed that the distribution of scores for his psychology class's last unit test was
not normal. In fact, the class results were positively skewed. According to this, which of the
following would be true?
Answer:
The mode and Median would be lower than the mean.
Step-by-step explanation:
The distribution data is positively skewed which means that most of the data would be towards the lower side. In this situation the mean is higher than the mode and median. Dr. Hammer has distribution data which is positively skewed so the mode and median will be lower than the mean.

The pendulum swings at an arc of 30 cm and its successive swings reduced to 10% of the previous swings. What is the total distance travelled by the pendulum after 5 swings? This problem is an example of what sequence?
Answer:
[tex]S_g= 33.333cm[/tex]
Step-by-step explanation:
From the question we are told that
Arc of 30 cm
10% reduction after each swing
Generally sum of geometric sequence is given by the equation
[tex]S_g=\frac{a(1-r^n)}{1-r}[/tex]
Mathematically solving for total distance traveled we have
[tex]S_g=\frac{30(1-(0.10^5)}{1-(0.10)}[/tex]
[tex]S_g=\frac{30}{0.9}[/tex]
Therefore the total distance traveled by the pendulum after 5 swings
[tex]S_g= 33.333cm[/tex]

What is the best description of AB?
9514 1404 393
Answer:
F altitude
Step-by-step explanation:
AB is perpendicular to triangle base XZ, so is an altitude of the triangle.
__
Additional comment
B is not the midpoint of XZ, so AB is not the median and not a bisector of XZ. Likewise, AB is not the angle bisector of angle A. (The triangle would have to be isosceles for AB to be a perpendicular bisector, median, and angle bisector.)
Eliminating the choices that can't work leaves the one that does work. AB is the altitude.

Altitude

what’s the answer and how did you get it? i’m confused
Answer:
The answer is 3.
Step-by-step explanation:
Because you should put the gh with gh, 2 is equivalent to 2 (so the 2 disappeared) and you only have 8-7=1 plus 2=3.
Answer: The given expression is 8g^2h-7gh+2
The degree of 8 g^2 h is 2, 1
The degree of - 7 g h is 1
The degree of 2 is 0
But the degree of expression will the highest degree of the indivisual expression of above i.e 3.
The answer is 3.
