What is the best way to describe the solution of this system of equations?
2x - 5y = 8
5y = -2x + 8
There are infinitely many solutions
There is one solution (4,0).
There are no solutions of the system.
There is one solution (0,4).
Answer:
There is one solution (4,0).
Answer:
x = 4 and y = 0
:-))
Step-by-step explanation:
2x - 5y = 8
x = 8 + 5y .........(1)
2
5y = -2x + 8
x = 8 - 5y ........(2)
2
get from 1 and 2
8 + 5y = 8- 5y
2 2
or, 10y = 0
or, y = 0
put the value of y in 1
x = 8 + 0
2
or, x = 4

g Which statement is correct? Group of answer choices A sample size of 1 is never acceptable. Judgment sampling is preferred to systematic sampling. Cluster sampling is useful when strata characteristics are unknown. Sampling without replacement introduces bias in our estimates of parameters.
Answer:
A sample size of 1 is never acceptable
Explanation:
A sample size of 1 is simply not statistically significant enough as to reach close to accurate conclusions based on sample data. Statistical tests using just one data point may not be enough to test data variability. Axrule of thumb or best practice is to have at least 10% sample size from the population. It is advised to have at least a sample size of 100 sayvpopulation is 1000 to be able to reach more valid conclusions from sample data.

Hey there!
“ (x⁴)³ ”
(x⁴) = x⁴ • x⁴ • x⁴
x⁴ = (x • x • x • x) * (x • x • x • x) * (x • x • x • x)
Number of x’s is 12
3 • 4 = 12, right?
Answer: x¹² ☑️

What is the value of the digit 2 in 82.6?
Answer:
It's equal to two "ones" ;v;
Step-by-step explanation:
The 8 is 80 "Tens", the 2 is 2 "ones" and the 6 is 6 tenths
Answer:
The value of 2 is 2The place value of 2 is onesI hope it helps ❤❤tan²Ф+sec²Ф=3
can someone solve this by finding all answers as the nearest whole degree
Recall that
tan²(x) + 1 = sec²(x)
for all x ≠ (2n + 1) 90°, where n is any integer. (That is, whenever x isn't an angle that is an odd multiple of 90°.)
Then
tan²(Φ) + sec²(Φ) = 3
tan²(Φ) + (tan²(Φ) + 1) = 3
2 tan²(Φ) + 1 = 3
2 tan²(Φ) = 2
tan²(Φ) = 1
tan(Φ) = ±√1
tan(Φ) = 1 or tan(Φ) = -1
Φ = tan⁻¹(1) + n 180° or Φ = tan⁻¹(-1) + n 180°
Φ = 45° + n 180° or Φ = -45° + n 180°
The first family of solution is the set of angles
{…, -315°, -135°, 45°, 225°, 405°, …}
and the second family is the set
{…, -405°, -225°, -45°, 135°, 315°, …}
(showing the solutions for n = -2 to n = 2)
You can condense the solution set into one family by noticing each angle is 45° plus some multiple of 90°, so that
Φ = 45° + n 90°
If you're looking for solutions in a given range, such as 0 ≤ Φ < 360°, then
Φ = 45°, 135°, 225° or 315°

whats the trans ___ and reflection ___
Given that,
A graph.
To find,
The trans and the reflection.
Solution,
When we slide a figure in any direction, it is called translation or trans.
In this case, option 1 is trans such that ABCD and A'B'C'D' are in same line.
When we flip a figure over a line, it is called reflection.
In this case, option Option 3 is reflection such that ABCD and A'B'C'D' are in opposite direction.

Triangle B because 128°>90°
Answer:
it should be correct ANSWER D TRIANGLE B
Step-by-step explanation:
"An obtuse triangle is a triangle in which one of the angles is an obtuse angle. (Obviously, only a single angle in a triangle can be obtuse or it wouldn't be a triangle.) A triangle must be either obtuse, acute, or right"

Troys truck has a 30 gallon gas tank and gets and average of 21 miles per gallon
Answer:
The answer is 630 miles using a 30 gallons tank.
Step-by-step explanation:
Well this question is incomplete, but if we are trying to find how many miles can 30 gallons give then the answer would be 630.
Why? Well since 21 miles = 1 gallon then 630 miles = 30 gallons.
Because 21 multiplied by 30 = 630.

A couple bought some stock for RM30 per share that pays an annual dividend of
RM0.90 per share. After 1 year, the price of the stock was RM33. Find the simple
interest rate on the growth of their investment.
Answer:
The answer is "13%".
Step-by-step explanation:
[tex]P_0 = 30\\\\D_1 = 0.90\\\\P_1 = 33\\\\[/tex]
[tex]Increase = 33 - 30 + 0.90\\\\[/tex]
[tex]= 3+0.90\\\\=3.90[/tex]
[tex]\text{Calculating increasing }\% :[/tex]
[tex]= \frac{3.90}{30} \times 100 \\\\= \frac{390}{30} \\\\= \frac{39}{3} \\\\= 13\%[/tex]

Aaron has between 100 and 110 baseball cards in his collection.If he counts his cards 2 at a time,he has 1 card left over.If he counts his cards 5 at a time,he has 2 cards left over . How many cards are in Aaron's collection ?
Answer:
110
Step-by-step explanation:
Answer:
107 cards
Step-by-step explanation:
So if you skip count by 5 up to one hundred, and then add 2, it's still and even number which the skip counting by 2 says won't work. So then skip count by 5 up to 105 and add 2 to get 107. Hope that makes sense! :)

Answer:
f(-1) = -1
Step-by-step explanation:
x = -1 falls in the middle segment, where -2 < x < 2. So, the applicable function definition is ...
f(x) = -2x -3
f(-1) = -2(-1) -3 = 2 -3
f(-1) = -1
