I think angle 8 because if you look at the angle 1 it is equivalent to angle 8 in length just in different positions

When f(x) = x2+9 and g(x) = x-9, find f(x)-g(x).

ohaa [14]

Answer:

$\huge{ \boxed{ \sf{ {x}^{2} - x + 18}}}$

Step-by-step explanation:

$\underline{ \text{Given}}:$

$\sf{f(x) = {x}^{2} +9 \: and \: g(x) = x-9}$

$\underline{ \text{To \: find}} : \sf{ \: f(x) \: - \: g(x)}$

Put the values:

$\mapsto{ \sf{ {x}^{2} + 9 - ( x - 9)}}$

While subtracting , sign of each term of the second expression changes.

$\mapsto{ \sf{ {x}^{2} + 9 - x + 9}}$

Add the numbers : 9 and 9

$\mapsto{ \boxed{ \sf{{x}^{2} - x + 18}}}$

Hope I helped!

Best regards! :D

An expression for the amount of money that Alicia earns in a day is 40y-3g.

Given that, Alicia runs a small business mowing yards in the summer. For every yard she mows, she earns $40. However, she spends part of this money on gasoline for her lawnmower. Each gallon of gasoline costs $3.

We need to find an expression for the given situation.

<h3>What is an expression?</h3>

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Now, expression =40y-3g

Therefore, an expression for the amount of money that Alicia earns in a day is 40y-3g.

Find the measure of the arc or angle indicated. NO LINKS.

Advocard [28]

9514 1404 393

Answer:

10. A) 120°

11. D) 40°

12. D) 54°

13. A) 101°

Step-by-step explanation:

The applicable rules of angles and arcs are ...

the whole is the sum of the parts
arcs of a circle total 360°
an inscribed angle intercepts an arc of twice its measure

10) Angles C and L intercept the same arc (DE) so will have the same measure.

15x = 16x -4

4 = x . . . . . . . . add 4-15x

arc DE = 2(15x) = 30(4) = 120 . . . degrees

11) Arc VW is twice the measure of angle X, so ...

9x +8 = 2(5x)

8 = x . . . . . . . . . subtract 9x

∠VXW = 5x = 5(8) = 40 . . . degrees

12) Arc EFG is twice the measure of angle W, so ...

70° +FG = 2(88°)

FG = 106° . . . . . . . . . subtract 70°

Arc FGW is twice the measure of angle E, so ...

106° +GW = 2(80°)

GW = 54° . . . . . . . . . . subtract 106°

13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.

RS +ST +TR = 360°

119° +2(70°) +TR = 360°

TR = 101° . . . . . . . . subtract 259°
