which algebraic expression is a polynomial?
it's the second one because the first has 2 over x which can't be a polynomial because it can't have a variable on the bottom same thing with the last one and the 3rd one it have a x in the square root sign
Answer:
B
Step-by-step explanation:
write standard form of line that is parallel to 2x + 3y= 4 and passes through the point (1, -4)
Answer:
2x + 3y = -10
Step-by-step explanation:
First convert the line into slope intercept form to find the slope of the line.
2x + 3y = 4
3y = 4 - 2x
y = -2/3x + 4/3
The slope of the line is -2/3. Parallel lines have the same slope so the slope for a line through the point (1,-4) will be -2/3. Substitute m = -2/3 and (1,-4) into the point slope of a line.
[tex]y --4 = -\frac{2}{3}(x-1)\\y + 4 = -\frac{2}{3}(x -1)[/tex]
Now convert the line into standard form by using the distributive property.
[tex]y + 4 = -\frac{2}{3}(x -1)\\y + 4 = -\frac{2}{3}x + \frac{2}{3}\\3y + 12 = -2x + 2\\2x + 3y + 12 = 2\\2x + 3y = -10[/tex]
What is the value of x in simplest radical form?
Answer:
x=37
Step-by-step explanation:
Since this is a right triangle, we can use Pythagorean theorem
a^2 +b^2 =c^2
12^2 +35^2 = x^2
144+1225= x^2
1369 = x^2
Take the square root
sqrt(1369) = sqrt(x^2)
37 = x
Answer:
x = 37
Step-by-step explanation:
Two leg lengths (35 and 12) are given, and the hypotenuse length is to be found. The Pythagorean Theorem links, these three quantities and enables us to find x quickly and easily:
35² + 12² = x² → 1225 + 144 = 1369 → x² = 1369
Find x by taking the square root of both sides:
√(x²) = ±√1369 → x = ± 37.
Because length is always +, omit x = -37 and keep x = +37.
7 1/2 divided by 1 9/10 simplified
Answer:
[tex]\large\boxed{3\dfrac{18}{19}}[/tex]
Step-by-step explanation:
[tex]\text{First step:}\\\text{Convert the mixed number to the improper fractions:}\\\\7\dfrac{1}{2}=\dfrac{(7)(2)+1}{2}=\dfrac{15}{2}\\\\1\dfrac{9}{10}=\dfrac{(1)(10)+9}{10}=\dfrac{19}{10}\\\\7\dfrac{1}{2}:1\dfrac{9}{10}=\dfrac{15}{2}:\dfrac{19}{10}\\\\\text{Dividing by a fraction is the same as multiplying by the inverse of a fraction}\\\\=\dfrac{15}{2}\cdot\dfrac{10}{19}=\dfrac{15}{2\!\!\!\!\diagup_1}\cdot\dfrac{10\!\!\!\!\diagup^5}{19}=\dfrac{15}{1}\cdot\dfrac{5}{19}=\dfrac{75}{19}=3\dfrac{18}{19}[/tex]
First, convert the mixed fractions into improper fractions. Then, turn the division problem into a multiplication problem by utilizing the concept of reciprocal. This gives us 75/19, or about 3.95 in decimal.
We first need to convert the mixed fractions into improper fractions. To do this, we multiply the whole number by the denominator of the fractional part and then add the numerator, placing this sum over the original denominator. This makes 7 1/2 into 15/2 and 1 9/10 into 19/10. The division problem 7 1/2 divided by 1 9/10 simplifies to 15/2 divided by 19/10.
Next, we remember that dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of a fraction is obtained by swapping the numerator and denominator. So, we change our division problem into a multiplication problem, transforming 15/2 divided by 19/10 into 15/2 * 10/19.
After multiplying these fractions, we get 150/38, which simplifies to 75/19, which is approximately 3.95 when converted to decimal.

Step-by-step explanation:
Let the number = x
Read carefully the sentence part beginning with 4 times larger
4* something
4 times larger than the square of 1/2 the number
4 * (x/2)^2
4*(x/2)^2 = x
4*x^2/4 = x
x^2 = x be very careful how you handle this. It looks like 0 might be an answer, but it isn't. If you divide x on both sides and you allow 0, you will get 0 / 0 and that is undefined. You must exclude that possibility with some sort of statement.

What is the area of a right triangle with vertices of (-2,-4),(2,-4), and (2,5)?
Answer:
A = 18
Step-by-step explanation:
The formula for the area of a triangle is
A = ½bh
b = x₂ - x₁ = 2 - (-2) = 2 + 2 = 4
h = y₂ - y₁ = 5 - (-4) = 5 + 4 = 9
A = ½ × 4 × 9 = 18

Answer:
15Step-by-step explanation:
∠6 and ∠7 are Alternate Interior Angles.
The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.
m∠6 = m∠7 → 4x - 15 = x + 30 add 15 to both sides
4x = x + 45 subract x from both sides
3x = 45 divide both sides by 3
x = 15
Answer:
[tex]\angle 6 =45^{\circ}[/tex]
Step-by-step explanation:
We are given that l || m
[tex]\angle 6 = 4x-15[/tex]
[tex]\angle 7 = x+30[/tex]
Since l || m
So, [tex]\angle 6 = \angle 7[/tex] (Alternate interior angles are equal )
So, [tex]4x-15 = x+30[/tex]
[tex]3x= 45[/tex]
[tex]x= 15[/tex]
[tex]\angle 6 = 4x-15=4(15)-15 = 45^{\circ}[/tex]
So, [tex]\angle 6 =45^{\circ}[/tex]

We factor out the 4 first since all numbers are divisible by 4. That leaves us with x^2+3x-18.
Then we factor this to get (x-3)(x+6).
So the factored form of the equation is 4(x-3)(x+6)
Step-by-step explanation:
The factors of the equation 4x²+12x -72 will be 4(x-3)(x+6).
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Factor out the 4 first since all numbers are divisible by 4. That leaves us with x² +3x -18.
4( x² +3x -18 ) = 4 ( x² + 6x - 3x -18 )
= 4 ( x(x+6) -3 (x + 6)
= 4 ( x + 6 ) ( x - 3 )
Hence, the factors are 4 ( x + 6 ) ( x - 3 ).

Answer:
The perimeter of both figures is equal to [tex]64\ units[/tex]

The perimeter of a square is equal to
[tex]P=4b[/tex]
where
b is the side length of the square
we have
[tex]b=8x\ units[/tex]
substitute
[tex]P=4(8x)=32x\ units[/tex]
step 2
we know that
The perimeter of a rectangle is equal to
[tex]P=2(L+W)[/tex]
we have
[tex]L=(5x+8)\ units[/tex]
[tex]W=(14)\ units[/tex]
substitute
[tex]P=2(5x+8+14)=10x+44\ units[/tex]

Equate both perimeters and solve for x
[tex]10x+44=32x[/tex]

Write an equation of each line that passes through the following points in slope-intercept form:
A (8, –1) and B (–4, 17)
Answer:
[tex]\large\boxed{y=-\dfrac{3}{2}x+11}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the point A(8, -1) and B(-4, 17). Substitute:
[tex]m=\dfrac{17-(-1)}{-4-8}=\dfrac{18}{-12}=-\dfrac{3}{2}[/tex]
The equation of a line:
[tex]y=-\dfrac{3}{2}x+b[/tex]
Put the coordinates of the point A(8, -1) to the equation of a line:
[tex]-1=-\dfrac{3}{2}(8)+b[/tex]
[tex]-1=-3(4)+b[/tex]
[tex]-1=-12+b[/tex] add 12 to both sides
[tex]11=b\to b=11[/tex]
Finally we have the equation of a line in a slope-intercept form:
[tex]y=-\dfrac{3}{2}x+11[/tex]

every 2 liters
Peggy:
90 tea bags
12 liters
You would simplify it by dividing 90 by 15, equaling 6. And 12 divided by 2, also equaling 6. Which would mean they are equal and Peggy's tea is exactly like Kermit's favorite iced tea.
Answer: The correct choice is
Choice (C) It is just right.
Step-by-step explanation: Given that Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water and Peggy made a 12 liter batch of iced tea with 90 tea bags.
We are to select the correct choice that describes the thinking of Kermit about Peggy's Iced tea.
The ratio of quantity of water and number of tea bags in Kermit's favorite iced tea is given by
[tex]R_k=2:15.[/tex]
And the ratio quantity of water and number of tea bags in Peggy's iced tea is given by
[tex]R_p=12:90=\dfrac{12}{90}=\dfrac{2}{15}=2:15.[/tex]
Since the ratio of water and number of tea bags in Peggy's iced tea is same as that in Kermit's favorite iced tea, so
Kermit will think that Peggy's iced tea is just right.
Choice (C) is CORRECT.
