Here’s the explanation!!!!!

Answer:

y = - 7

Step-by-step explanation:

Since the solution is always the same for y, y equals that solution and does not depend on x.

Answer: Yellow option

Step-by-step explanation:

The points noted are (0,-2) and (3,-1)

So the slope is (-2--1)/(0-3) = -1/-3 = 1/3

So options blue, green and red are out.

So the only option is yellow

Answer: C is your answer

Step-by-step explanation:

Answer:

23 years old

Step-by-step explanation:

Given the following question:
Ricky is 5 years older than Ciara...
6 years their ages will equal 53 years of age.

So, we have to remember that in six years their ages will equal 53 and one is five years older than the other.

[tex]23+6=29[/tex]
[tex]18+6=24[/tex]
[tex]29-5=24[/tex]
[tex]29+24=53[/tex]
[tex]29-6=23[/tex]
[tex]=23[/tex]

Which means Ricky as of right now is "23 years of age" and Ciara as of right now is "18 years of age".

Hope this helps.

Answer:

2 different ways

Step-by-step explanation:

You are looking at the factors of 60.

1×60 does not work, too many pictures in a row.

2×30 does not work, too many pictures in a row.

3×20 THIS WORKS!

4×15 THIS ALSO WORKS!

5×12 Nope, too many rows

6×10, no, too many rows

So there's just two ways to arrange the pictures.

[tex]\qquad \sf  \dashrightarrow \: f(2x) = \tan(2x) [/tex]

[tex]\qquad \sf  \dashrightarrow \: f(2x) = \dfrac{2 \tan(x) }{1 - { \tan {}^{2} (x) }^{} } [/tex]

replace tan(x) with f(x) in the given equation ~

[tex]\qquad \sf  \dashrightarrow \: f(2x) = \dfrac{2 (f(x) )}{1 - { (f {}^{} (x)) {}^{2} }^{} } [/tex]

The expression that was proved is [tex]tan2x=\frac{2[f(x)]}{1-[f(x)^2]}[/tex]

Given the trigonometry identity

f(x) = tanx

f(2x)  tan2x

From double angle theorem;

[tex]tan2x=\frac{tanx+tanx}{1-tanx(tanx)} \\tan2x=\frac{2tanx}{1-tan^2x}[/tex]

Since f(x) = tan(x), substitute into the result to have:

[tex]tan2x=\frac{2[f(x)]}{1-[f(x)^2]}[/tex] (Proved)

Answer:

14 1/3

Step-by-step explanation:

3 × 4 7/9

=3 × 43/9

= 43/3

= 14 1/3

Answer:

43/3

Simply 14⅓

Step-by-step explanation:

4 7/9 can also be expressed as (4x9+7)/9 = 43/9

3x43/9 = 43/3

Answer: GCF = 6, LCM = 72

Step-by-step explanation:

The prime factorization of 18 is 2*3^2 and the prime factorization of 24 is 2^3*3

Therefore, the gcf is 2*3 = 6.

The lcm is 2^3*3^2 = 8*9 = 72

Answer:

3=D

4=B

5=A

Step-by-step explanation:

Answer:

It's 5

Step-by-step explanation:

-4x+5=-15 (subtract 5)

-4x=-20 (divide by -4)

x=5

Step-by-step explanation:

Work backwards. First, create a function:

f(x) = x

First, instead of adding 5, subtract it:

f(x) = x - 5

Then, divide by -4:

f(x) = (x - 5) ÷ -4

Then plug in -15:

f(-15) = (-15 - 5) ÷ 4

= -20 ÷ -4

= 20 ÷ 4

= 5

Solve 2nd equation:

Surface area = 96 cm².

Answer:

53 dollars and 33 cents

Step-by-step explanation:

53.33

We are given –

Paulo has R$ 80.00 and Carlos has 2/3 of that amount.

We are asked to find, how much Carlos owns and how much they have together.

Explanation :-

At first, we just need to multiply 80by 2, and then we will divide the value by 3, so we find that:

[tex]\qquad[/tex][tex] \bf \longrightarrow 80 \times 2 = 160[/tex]

[tex]\qquad[/tex][tex] \bf \longrightarrow \dfrac{160}{3} = 53.3[/tex]

Therefore, we find that Carlos has 53.3 R$.

Now to find out how much they have together. We have to add Paul's amount to Carlos' amount for that.

[tex]\qquad[/tex][tex] \bf \longrightarrow 53.3 +80 =133.3[/tex]

Henceforth, they both have 133.3 R$. together.

Answer:

y = -2x + 9

Step-by-step explanation:

slope intercept form : y = mx + b

where m = slope and b = y intercept

first let's find the slope

slope formula :

[tex]m = ( \frac{y2 - y1}{x2 - x1} )[/tex]

where the x and y values are derived from the given points

here we are given (2,5) and (6,-3)

(x1,y1) = (2,5) so x1 = 2 and y1 = 5

(x2,y2) = (6,-3) so x2 = 6 and y2 = -3

we now plug these values into the formula

recall formula

[tex]m= ( \frac{y2 - y1}{x2 - x1} )[/tex]

plug in x1 = 2, y1 = 5, x2 = 6 and y2 = -3

m = (-3 - 5) / ( 6 - 2 )

m = (-8)/(4)

m = -2

the slope is -2

now to find the y intercept we plug in the slope and the x and y value of a given point into slope intercept form and solve for b

y = mx + b

given point : (2,5) x = 2 , y = 5, m = -2

5 = -2(2) + b

5 = -4 + b

9 = b

so the equation would be y = -2x + 9

$8000

Step-by-step explanation:

With the provided values you get the equation

1800+.15x=3000

with x being the amount of sales he needs

1. 3000-1800=1200

gives 1200=.15x

2. 1200/.15 = 8000

so x = 8000
