Question 3 of 10 If f(x) = 3x – 12, what is f(2)? A. –6 B. 6 C. 18 D. –18
Answer:
Your answer is D
Step-by-step explanation:
f(2) This means that x is 2, so you can plug in 2 for "x" in the equation
f(x) = 3x - 12
f(2) = 3(2) - 12
f(2) = 6 - 12
f(2) = -6

y =
Answer:
[tex]y = 2x^4[/tex]
Step-by-step explanation:
The given statement can be represented as:
[tex]y\ \alpha\ x^4[/tex]
[tex]x =3; y = 162[/tex]
Given
Represent this as an equation
[tex]y\ \alpha\ x^4[/tex]
Convert variation to equation
[tex]y = kx^4[/tex]
Where k is a constant of variation.
Substitute [tex]x =3; y = 162[/tex]
[tex]162 = k * 3^4[/tex]
[tex]162 = k * 81[/tex]
Solve for k
[tex]k = 162/81[/tex]
[tex]k =2[/tex]
To get the equation, we have:
[tex]y = kx^4[/tex]
Substitute 2 for k
[tex]y = 2x^4[/tex]
The equation describing the relationship of the given variables is [tex]y=\frac{81}{162}x^4[/tex]
If y varies directly to the fourth power of x, this can be expressed as:
[tex]y \alpha x^4\\y=kx^4\\[/tex]
Given that x = 3 and y = 162, the equation becomes;
[tex]162 = k(3^4)\\162 = 81k\\k=\frac{81}{162}[/tex]
Substitute the value of k into the expression above to have:
[tex]y=kx^4\\y=\frac{81}{162}x^4[/tex]
Hence the equation describing the relationship of the given variables is [tex]y=\frac{81}{162}x^4[/tex]

Solve the formula V = 1/3b^2 h for b.
Answer:
[tex]b=\sqrt{\frac{3V}{h}}[/tex]
Step-by-step explanation:
To solve a formula for one of its variables do that
Underline the variableSeparate it on one side and the other terms on the other sideMake its coefficient equals 1Let us use these steps to solve our question
∵ V = [tex]\frac{1}{3}[/tex] b²h
→ Underline b
∴ V = [tex]\frac{1}{3}[/tex] b²h
→ Multiply both sides by 3 to cancel the denominator on the right side
∴ 3V = b²h
→ Divide both sides by h to move it to the other side
∴ [tex]\frac{3V}{h}=b^{2}[/tex]
→ To find b take √ for both sides
∴ [tex]\sqrt{\frac{3V}{h}}=\sqrt{b^{2} }[/tex]
→ The square root will cancel the power 2 of b
∴ [tex]\sqrt{\frac{3V}{h}}=b[/tex]
→ Switch the two sides
∴ [tex]b=\sqrt{\frac{3V}{h}}[/tex]

Find 3 equivalent fractions to this number. 16/40
Answer:
[tex]\frac{8}{20}[/tex] , [tex]\frac{4}{10}[/tex] , [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
to find equivalent fractions multiply or divide the numerator and denominator by the same value.
[tex]\frac{16}{40}[/tex] ( divide numerator/ denominator by 2 )
= [tex]\frac{8}{20}[/tex] ( divide numerator/ denominator by 2 )
= [tex]\frac{4}{10}[/tex] ( divide numerator/ denominator by 2 )
