9x - 2y = 19, 7x = 21
System of Equation
9x - 2y = 19, 7x = 21
7x = 21
=> x = 21/7
= x = 3 —————(1)
9x - 2y = 19
=> 9(3) - 2y = 19 [From (1)]
=> 27 - 2y = 19
=> -2y = 19 - 27
=> -2y = -8
=> y = -8/-2
=> y = 8/2
=> y = 4
So, x = 3 and y = 4.

Select the correct answer. Let f(x) and g(x) be polynomials as shown below.
Answer:
f(x) and g(x) are closed under multiplication because when multiplied, the result remains a polynomial.
Step-by-step explanation:
First, to be closed means that once an operation has commenced, the result is a polynomial, just like the two original ones.
When polynomials are multiplied, exponents simply add together, and constants are multiplied. A polynomial is a finite sum of terms in which all variables have whole numbered exponents.
In this scenario, when we multiply polynomials, exponents are solely added together, and one whole number plus another is still a whole number. Similarly, constants multiplied by constants stay as constants, and constants multiplied by variables keeps it in polynomial form. (e.g. 3 * x² makes it 3x², and 3x² is fine in a polynomial).
Therefore, given these facts, f(x) and g(x) are closed under multiplication because when multiplied, the result remains a polynomial.
The yearbook staff receive 75 submissions for yearbook articles. Paul will accept 2/5 of all submissions. Currently, Paul plans for the yearbook to have 156 pages.
Answer 813.8
Step-by-step explanation:
Well 813.8 is the answer. Why? Lets talk it out if there are 75 submissions and it says Paul will accept 2/5 of the submissions so we have to do is 75- 2/5 will be 74.6 and multiply by 13 because 13 pages is in a article so we got 969.8 and then minus 156 because it asking us how many "more" pages they need so 813.8 is the answer if you subtract 969.8 and 156.

Answer:
32 square units.
Step-by-step explanation:
The shape is made up of three parts, a rectangle in the middle, and two identical triangle on each side.
Rectangle: base = 2, height 8, area = 16
Each triangle: (vertical) base = 8, (horizontal) height = 2
Area = base * height /2 = 2*8/2 = 8
Total area = 8 + 16 + 8 = 32
Greatest common factor for 28y^7x^4u^3 and 8x^4u^5
Answer:
Step-by-step explanation:

rewrite those 2 terms to better see what they have in common
[tex]4*7 *x^{4} *u^{3} *y^{7} \\4*2*x^{4}*u^{3} *u^{2}[/tex]
because, 4*7 =28, 4*2=8, u³*u² =u^5, and multiplication is commutative

Luigi decided to grab lunch at Howell's Cafe with his friends. The bill for their meals was the $36.50. The restaurant charges a 7% tax. How much is the total bill?
Answer:
$39.055
Step-by-step explanation:
100% + 7% = 107%
[tex]\frac{y}{36.5} :\frac{107}{100}[/tex]
y · 100 = 107 · 36.5
100y = 3905.5
100y ÷ 100 = 3905.5 ÷ 100
y = 39.055

k is a prime number and f(x) = k has no solutions.
Find the possible values of k.
Answer:
Suppose x∈R is such that x+20x=p is a prime. Then x2−px+20=0 , and this equation has a solution x∈R if and only if p2–80≥0 . So the primes which admit no real solution are those that satisfy p<80−−√ , or 2 , 3 , 5 , and 7 . ■
Step-by-step explanation:
E? <3
The primes which accept no real solution exist as those that satisfy
p<[tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.
What is a prime number?A prime number exists as a real number greater than 1 whose only factors that exist are 1 and itself. A factor exists as an entire number that can be divided evenly into another number. The first prime numbers exist 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Numbers that contain better than two factors exist named composite numbers.
If the function f(x) = (20/x) + x = k. Suppose x∈R exists such that x+20x=p exists a prime. Then [tex]$x^2-px+20=0[/tex], and this equation contains a solution x∈R if and only if [tex]$p^2-80[/tex] ≥ 0. So the primes which accept no real solution exist as those that satisfy p < [tex]\sqrt{80}[/tex], or 2, 3, 5, and 7.

Brian sent 9 more messages than salma and Chang sent 2 times more than Brian and they have 55 messages total how many messages do they have each
Answer:
See explanation
Step-by-step explanation:
Let
x = number of messages Salma sent
x + 9 = number of messages Brian sent
2(x + 9) = number of messages Chang sent
Total messages sent = 55
x + (x + 9) + 2(x + 9) = 55
x + x + 9 + 2x + 18 = 55
4x + 27 = 55
4x = 55 - 27
4x = 28
x = 28/4
x = 7
Number of messages Salma sent = x = 7 messages
Number of messages Brian sent = x + 9
= 7 + 9
= 16 messages
Number of messages Chang sent = 2(x + 9)
= 2(7 + 9)
= 2(16)
= 32 messages
What is an equation of the line that passes through the points (6, -3)and (−6,−5)?
Answer:
y = 1/6x -4
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
m=(-5 - -3)/( -6 -6)
= (-5+3)/ (-6-6)
= -2/-12
= 1/6
The slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = 1/6 x +b
Substitute a point into the equation
-5 = 1/6(-6) +b
-5 = -1+b
Add 1 to each side
-4 = b
y = 1/6x -4
Answer:
y=1/6x-4

If the can is full of paint with a radius of 5 and height of 14 inches, what is the total amount of paint in the can?
Answer:
1,099 cubic inch or 18.01 liter
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Radius (r) = 5 inches
Height (h) = 14 inches
So, Volume of can = π[tex]r^{2}[/tex]h
By putting the value in the formula, we get
= π [tex]5^{2}[/tex] × 14
= π 25 × 14
= 350π
= 350 × 3.14
= 1,099 cubic inch
As 1 liter = 61.02 cubic inch
So, 1,099 ÷ 61.02 = 18.01 liter

Which equation shows a line with the
slope of 5 that passes through point (2, -3)?
Answer:
y = 5x - 13
Step-by-step explanation:
point slope form: y - y1 = m (x - x1)
plug in: y1 = -3, x1 = 2, m = 5
y - (-3) = 5 (x - 2)
y + 3 = 5x - 10 <- simplify and expand
y = 5x - 13 <answer for slope intercept
equation: y = 5x - 13

Find the zeros of y = x2 - 6x – 4 by completing the square.
O A. x = 3 + 5
B. X = +3
C. X = 3 + 13
D. x.-3113
Answer:
√13 + 3 = x
-√13 + 3 = x
Step-by-step explanation:
y = x² - 6x - 4
0 = x² - 6x - 4
0 + 13 = x² - 6x - 4 + 13
13 = x² - 6x + 9
13 = (x-3)²
±√13 = x-3
±√13 + 3 = x
√13 + 3 = x
-√13 + 3 = x
