Answer:

PB = 1.8

Step-by-step explanation:

PQ = 8 cm, BC = 10 cm and AB = 9 cm

∆ABC is similar to ∆APQ.

Therefore:

[tex] \frac{AB}{AP} = \frac{BC}{PQ} [/tex]

Plug in the values

[tex] \frac{9}{AP} = \frac{10}{8} [/tex]

Cross multiply

AP × 10 = 8 × 9

AP × 10 = 72

Divide both sides by 10

AP = 7.2

PB = AB - AP

PB = 9 - 7.2

PB = 1.8

Answer:

x=10

Step-by-step explanation:

3x+10=6x-20 Set the angles equal to each other b/c they are alt. int. angles.

-3x       -3x Subtract by 3x on both sides to get x by itself

----------------

+10    =3x-20

+20         +20 Add 20 to both sides to get x by itself

---------------------

30    =3x

/3        /3 Divide both sides by 3 to get x by itself

-------------

10    =x

x=10 Write x first.

Answer:

Step-by-step explanation:

Step one.

Read the slope

-1/4

Step two

Put the slope in the general equation

y = mx + b

y = -1/4 x + b

Step 3

Put the point into the equation from step 2

(-8,5)

5 = -1/4  -8   + b

5 = 2 + b                   Subtract 2 from both sides

5-2 = b

b = 3

Step 4

Write the entire equation

y =   -1/4 x + 3

Answer:

The slope is -2

Step-by-step explanation:

(−4,7);(2,−5)

(x1,y1)=(−4,7)

(x2,y2)=(2,−5)

m= y2−y1 /x2−x1

−5−7 /2−4

−12 /6

−2

Answer:

x=28

Step-by-step explanation:

-2(3x-9)+5x =-10

now we times -2 to to the inside of the parenthese

giving us

-6x+18 +5x= -10

add like terms

add -6x and 5x

-1x+18=-10

now we add like terms of the constants

minus 18 on  both sides

-1x=-28

now divide by -1

x = 28

Answer:

x = 28

Step-by-step explanation:

First, remove the parentheses by distributing -2.

-6x + 18 + 5x = 10

Next, collect the like terms.

-x + 18 = -10

Next, move the constant to the right-hand side and change its sign.

-x = -10 - 18

Next, calculate the difference

-x = -28

Lastly, change the signs on both sides of the equation.

x = 28

These are the steps to answer this equation.

the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.

The correct graph is attached below.

Step-by-step explanation:

Given the function equation

Given that the cost of each ticket is $10.

It means:

at x = 0, y = 10(0) = 0                ∵ cost of 0 ticket

at x = 1, y = 10(1) = 10                 ∵ cost of 1 ticket

at x = 2, y = 10(2) = 20               ∵ cost of 2 tickets

at x = 3, y = 10(3) = 30                ∵ cost of 3 tickets

at x = 4, y = 10(4) = 40                ∵ cost of 4 tickets

at x = 5, y = 10(5) = 50                 ∵ cost of 5 tickets

Now, observe the ordered pairs points on the right-hand graph of the first diagram.

This graph has the following ordered pairs:

Answer:

f(5.5)≈27.32

Step-by-step explanation:

The exponential function which satisfy the f(4.5) = 23 and f(8) = 42 will be 10.60([tex]1.19^{x}[/tex]).

In mathematics, an exponential function is a relationship of the type y = ax, where x is an independent variable that spans the entire real number line and is expressed as the exponent of a positive number.

Suppose the exponential function is f(x) = a[tex]b^{x}[/tex].

As per the given,

f(4.5) = 23

Put x = 4.5 as

23 = a[tex]b^{4.5}[/tex]               (1)

As per the given,

f(8) = 42

Put x = 8 as

42 = ab⁸                  (2)

Divide equation (2) by (1) as,

ab⁸  / a[tex]b^{4.5}[/tex] = 42/23

[tex]b^{8-4.5}[/tex] = 42/23

b = 1.19

Again put into (2)

42 = a(1.19)⁸

a = 10.60

Thus, the function will be f(x) = 10.60([tex]1.19^{x}[/tex]).

Hence "The exponential function which satisfy the f(4.5) = 23 and f(8) = 42 will be 10.60([tex]1.19^{x}[/tex])".

Answer:

Subtract 3.6 from both sides.

Step-by-step explanation:

Given

[tex]x + 3.6 = -1.7[/tex]

Required

Solve in one step

There are two ways to go about it.

1. Collect Like Terms

[tex]x + 3.6 = -1.7[/tex]

3.6 and -1.7 are like terms, so the equation becomes

[tex]x = -1.7 - 3.6[/tex]

[tex]x = -5.3[/tex]

2. Subtract 3.6 from both sides

[tex]x + 3.6 = -1.7[/tex]

This becomes

[tex]x + 3.6 - 3.6 = -1.7 - 3.6[/tex]

[tex]x = -5.3[/tex]

Hence, the last option answers the question.
