Answer:

y = 17x

Step-by-step explanation:

This question is a problem under "Enlargement and Similarities"

Triangle ABC is enlarged to form triangle ADE.

This means AB is enlarged to form AD and CB is enlarged to form ED. So I'm order to find x we compare the ratio of AD and AB to CB and ED.

AB/AD =CB/ED

9/(9+6) = 3/x

=9/15 = 3/x

Multiplying through by 15x

= 9x =45

= x= 45/9

=x=5

Answer:

The y-value (output) is equal to 1

Step-by-step explanation:

f(x) = 1

f(x) takes the place of y, so this could be rewritten as

y = 1

Answer:

Step-by-step explanation:

x+5y=-27

-2x-5y=24

If the signs are the same u minus if they are different u add

So they are different were gonna add

x+5y=-27

-2x-5y=24

-1=-3

You cant divide it further x=-3

Next were gonna subsitute in any equation

x(-3)+5y=-27

-3+5y=-27

+3 to -27

-7+3=-24

5y=24

24/5=4.8 y=4.8

Answer:

-17=x-15 +15

-2=x

Step-by-step explanation:

prove me wrong

-17 = x - 15

Move -15 over to -17, it becomes a positive.

15 - 17 = x

15 - 17 = -2

x = -2

Answer:

Dimes: 10 dimes

Nickles: 6 nickels.

Step-by-step explanation:

Dimes: 10 x 0.10 = 1.00

Nickels: 6 x 0.05 = 0.30

$1.00 + $0.30 = 1.30

By the table, it seems to be that f = 1/2x

Answer:

The answer is t.

Step-by-step explanation:

We need to find the sum of opposite of - 10t and t - 10t.

Opposite of -10t = 10 t

So,

10t + (t-10t)

Grouping the numbers,

(10t+(-10t)) + t

= 0 + t

= t

Hence, the answer is t.

Answer:

3/2

Step-by-step explanation:

The ratio of the quarts of tomatoes to the number of the baskets. in the simplest form is 3:2.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given that, You make 9 quarts of tomato sauce from 6 baskets of tomatoes.

We need to find the ratio, between quarts of tomatoes and number of the baskets.

There are 9 quarts of tomato for 6 baskets,

Therefore, the required ratio will be = quarts of tomato : number of the baskets.

= 9 : 6

= 3 : 2

Hence, the ratio of the quarts of tomatoes to the number of the baskets. in the simplest form is 3:2.

Answer: ↓↓↓

Step-by-step explanation:

Part A

131.5 or $131,500 is the starting value of the plane X before it started to depreciate.

Part B (They meant plane Y as in plane Y but plane B as in the second plane, look at the table and Part C)

b (m) = 177,233 (0.024)^m

$177,233 is the starting value of plane Y.

The value depreciates by 2.4% and that is the same as 0.024, except 0.024 is in decimal form.

Part C

b (t) = 177,233 (0.024 x 12)^t

b (t) = 177,233 (0.288)^t

I multiplied 12 by the depreciation because for the whole equation to actually show the depreciation in years I had to solve how much the plane would depreciate in 1 year. So, since 12 months is 1 year, I multiplied 12 by 0.024.

That's it! I hope I'm right because this took a lot of thinking lol

Answer:

[tex]\dfrac{6x+2}5}[/tex]

Step-by-step explanation:

The given expression is :

[tex]\dfrac{3x}{5}+\dfrac{2}{5}+\dfrac{3x}{5}[/tex]

We need to write the equivalent expression for the above expression.

Taking like terms together,

[tex]=(\dfrac{3x}{5}+\dfrac{3x}{5})+\dfrac{2}{5}\\\\=\dfrac{3x+3x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x+2}5}[/tex]

So, the equivalent expression is [tex]\dfrac{6x+2}5}[/tex].

[tex]\huge\boxed{5p;\ (p+1)}[/tex]

Step-by-step explanation:

[tex]5p^3+45p^2+40p=5p(p^2+9p+8)=5p(p^2+p+8p+8)\\\\=5p\bigg[p(p+1)+8(p+1)\bigg]=5p(p+1)(p+8)\\\Downarrow\\\boxed{5p};\ \boxed{(p+1)};\ \boxed{(p+8)}[/tex]

the factors for the given expression are

[tex]5p, p+1, p+8[/tex]

Given :

Given expression is [tex]5p^3 + 45p^2 + 40p[/tex]

Lets factor the given trinomial by factoring out GCF that is greatest common factor

Lets find out GCF from the given expression

all the terms are divisible by 5  and also we have 'p' in common

so GCf is 5p

[tex]5p^3 + 45p^2 + 40p\\5p\left(p^2+9p+8\right)\\[/tex]

Now we factor [tex]\left(p^2+9p+8\right)[/tex]

Product is 8  and sum is 9

So factors are 8  and 1

[tex]5p\left(p^2+9p+8\right)\\5p\left(p+1\right)\left(p+8\right)[/tex]

So the factors are

[tex]5p, p+1, p+8[/tex]
