Answer:
p(- 3) = 0
Step-by-step explanation:
Substitute x = - 3 into p(x) , that is
p(- 3) = - 12(- 3) - 36 = 36 - 36 = 0
Which function is most likely graphed on the coordinate plane below? f(x) = 3x – 11 f(x) = –4x + 12 f(x) = 4x + 13 f(x) = –5x – 19
Answer:
D
Step-by-step explanation:
It's D on Enginuity
The graph of the function in the coordinate plane is f(x) = –5x – 19.
What is a Graph?In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.
As per the given diagram:
The x intercept of the line = -ve
The y intercept of the line = -ve
For f(x) = 3x - 11
x intercept = +ve
y intercept = -ve
Hence, not possible
For f(x) = -4x + 12
x intercept = +ve
y intercept = +ve
Hence, not possible
For f(x) = 4x + 13
x intercept = -ve
y intercept = +ve
Hence, not possible
For f(x) = -5x - 19
x intercept = -ve
y intercept = -ve
Hence, possible
The function plotted on the coordinate plane is f(x) = –5x – 19.

express 15x^1/3 y ^1/5 using a radical
Answer:
C
Step-by-step explanation:
[tex]15x^{\frac{1}{3} }y^{\frac{1}{5} }\\\\=15x^{\frac{5*1}{5*3} }y^{\frac{3*1}{3*5} }\\\\=15x^{\frac{5}{15} }y^{\frac{3}{15} }\\\\=15\sqrt[15]{x^{5}y^{3} } \\\\[/tex]
The expression 15x^(1/3) y^(1/5) can be written as 15 * ∛x * ∜y
How to express 15x^(1/3) y^(1/5) using a radical?To express 15x^(1/3) y^(1/5) using a radical, we will start by writing each term with a common base.
Now express x^(1/3) as a radical. We know x^(1/3) is the cube root of x, this is rewritten as ∛x.
Now, we express y^(1/5) as a radical. We know that y^(1/5) is the fifth root of y, so we is rewritten it as ∜y.
Putting it all together, we have:
15x^(1/3) y^(1/5) = 15 * ∛x * ∜y.

Answer:
x = ±√17
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other.
Also note that the x has a power of 2. To isolate the x, simply root both sides of the equation.
x² = 17 ; √x² = √17 ; x = ±√17

whatssssssssssssss divied 3/7 and 2/3
Answer:
9/14
Step-by-step explanation:
3/7÷2/3=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
3/7×3/2=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
3×3
7×2= 914
This fraction cannot be reduced.
Therefore:
3/7÷2/3=9/14
Answer:
9/14
Step-by-step explanation:
3/7 ÷ 2/3= 9/14
To divide a fraction, you have to flip the second fraction and multiply.
3/7 × 3/2 = 9/14
9/14 is in simplest form.

Let f(x)=4x^2+13x-12 and g(x)=x+4. Perform the function operation
F•g(x)
Please help!!!
Answer: 4x³+29x²+40x-48
Step-by-step explanation:
To solve f(x)·g(x), you multiply them together.
(4x²+13x-12)(x+4) [distribute by FOIL]
4x³+16x²+13x²+52x-12x-48 [combine like terms]
4x³+29x²+40x-48
Now, we know that f(x)·g(x)=4x³+29x²+40x-48.
Answer: 4x³+29x²+40x-48
Step-by-step explanation:
The product of two functions=f(x)·g(x)=fg(x)
Use FOIL method to simplify expression.
FirstOuterInner Laterf(x)·g(x)
=(4x²+13x-12)·(x+4)

3(-X+4)=7x-8. Yeahhhh...
Hey there!☺
[tex]Answer:\boxed{x=2}[/tex]
[tex]Explanation:[/tex]
[tex]3(-x+4)=7x-8[/tex]
Let's start by simplifying both sides. First, we distribute.
[tex](3)(-x)+(3)(4)=7x+-8[/tex]
[tex]-3x+12=7x+-8[/tex]
[tex]-3x+12=7x-8[/tex]
Now let's subtract 7x from both sides.
[tex]-3x+12-7x=7x-8-7x\\-10x+12=-8[/tex]
Now we will subtract 12 from both sides.
[tex]-10x+12-12=-8-12\\-10x=-20[/tex]
In our last/final step, we will divide both sides by -10.
[tex]\frac{-10x}{-10}=\frac{-20}{-10}[/tex]
Now simplify -20/-10.
[tex]-20/-10=2[/tex]
[tex]x=2[/tex]
Hope this helps!
which expression is equivalent to the given expression square root of 45
Answer:
[tex]3 \sqrt{5} [/tex]
Step-by-step explanation:
Solve using Surd
[tex] \sqrt{45} = \sqrt{9 \times 5} \\ = \sqrt{ {3}^{2} \times 5 } \\ = 3\sqrt{5} [/tex]
The expression 3√5 will be equivalent to a square root of 45.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given the expression √(45)
⇒ √(9×5)
⇒ √(3²×5)
⇒ √(3²)√(5)
Since the square root of a square is the same number
So,
⇒ 3√5
Hence "The expression 3√5 will be equivalent to a square root of 45".
