Answer:

f(g(x))=9-x-[tex]x^{2}[/tex]

Step-by-step explanation:

Given ,

f(x)=9-x

g(x)=[tex]x^{2}[/tex] +x

here,.

fog

=f(g(x))

=f([tex]x^{2}[/tex] +x)

=9-([tex]x^{2}[/tex] +x)

=9-[tex]x^{2}[/tex] -x

=9-x-[tex]x^{2}[/tex]

Replace x in the equation and see which one equals the y values:

The answer is f(x) = 2x - 1

Answer:

If you mean [tex]\sqrt{ab^{2}[/tex] then the answer is [tex]b\sqrt{a}[/tex]

Step-by-step explanation:

Answer:

ab

Step-by-step explanation:

Original expression:

[tex]\sqrt[]{(ab)^2}[/tex]

Apply the rule [tex](xy)^c=x^c \cdot y^c[/tex]

[tex]\implies \sqrt[]{(ab)^2}=\sqrt[]{a^2 \cdot b^2}[/tex]

Apply the rule [tex]\sqrt{xy}=\sqrt{x} \sqrt{y}[/tex]

[tex]\implies \sqrt[]{a^2 \cdot b^2}=\sqrt{a^2} \sqrt{b^2}[/tex]

Apply the rule [tex]\sqrt{x^2}=x[/tex]

[tex]\implies \sqrt{a^2} \sqrt{b^2}=ab[/tex]

Answer

18,080

Explantion

400x10=4000x4=16000

400x5=2000

2000+16000=18000

400×.2=80

cause 20% of 400 is 80

so total is 18,080

Answer:

Its Simple All the angles in a triangle adds up to 180°

Step-by-step explanation:

∠A + ∠ B + ∠C = 180° NO matter what. You can also use this in inverse If you have two out of three angles then you can add the two angles you have and subtract the from 180 to get the measurement of the 3rd angle.

Answer:

[tex]\sf y \leq \dfrac34x[/tex]

Step-by-step explanation:

Choose 2 points on the line:  (0, 0) and (4, 3)

[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-0}{4-0}=\dfrac34[/tex]

point-slope form of linear equation:  [tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-0=\dfrac34(x-0)[/tex]

[tex]\implies \sf y=\dfrac34x[/tex]

Solid line : ≤ or ≥

Dashed line: < or >

Therefore as the line is solid, and the shading is below the line,

[tex]\implies \sf y \leq \dfrac34x[/tex]

Slope:-

[tex]\\ \tt\Rrightarrow m=\dfrac{6+3}{8+4}=\dfrac{9}{12}=\dfrac{3}{4}[/tex]

Equation of line in point slope form

[tex]\\ \tt\Rrightarrow y+3=3/4(x+4)[/tex]

[tex]\\ \tt\Rrightarrow y+3=3/4x+3[/tex]

[tex]\\ \tt\Rrightarrow y=3/4x[/tex]

equation of shaded region

[tex]\\ \tt\Rrightarrow y\leqslant 3/4x[/tex]

Answer:

v = [tex]\frac{7\sqrt{2} }{2}[/tex]

u = [tex]7[/tex]

Step-by-step explanation:

First, the angle on the far left is also 45 degrees.

So, v is equal to [tex]\frac{7\sqrt{2} }{2}[/tex] because this is a 45-45-90 triangle, so the sides opposite the 45-degree angles are congruent.

However, u is the side opposite the 90-degree angle, so it is equal to the other side value, multiplied by [tex]\sqrt{2}[/tex].

So, [tex]\frac{7\sqrt{2}}{2}*\sqrt{2}[/tex] is equal to:

[tex]7[/tex]

Answer:

[tex]1\frac{5}{12}[/tex]

Step-by-step explanation:

[tex]1\frac{2}{3}-\frac{1}{4}[/tex]

[tex]\mathrm{Subtract\;Whole\;Number}[/tex]

[tex]1-0=1[/tex]

[tex]\mathrm{Combine\;fraction}[/tex]

[tex]\frac{2}{3}-\frac{1}{4}:\frac{5}{12}[/tex]

[tex]=1+\frac{5}{12}[/tex]

[tex]=1\frac{5}{12}[/tex]

Hence, the answer is 1 5/12

~Lenvy~

1. Convert the 1 and 2/3 from mixed partial fractions to improper fractions to make it a bit simpler to calculate

⇒ [tex]1\frac{2}{3} = \frac{5}{3}[/tex]

2. Now lets the change the base of both fractions into a common denominator and solve

⇒ [tex]\frac{5}{3}-\frac{1}{4} = \frac{5*4}{3*4} -\frac{1*3}{4*3} =\frac{20}{12}-\frac{3}{12} =\frac{20-3}{12} =\frac{17}{12} = 1\frac{5}{12}[/tex]

Answer: [tex]\frac{17}{12}[/tex] or [tex]1\frac{5}{12}[/tex]

Hope that helps!
