Answer:

we have:

10*(9x-1+10)=9(9+11)

10(9x+9)=9*20

9(x+1)=9*20/10

x+1=18/9

x+1=2

x=2-1

x=1

Now

RS:9×1-1=8

if a point on the graph of a proportional relationship is located at 3,4, can you determine the constant of proportionality? exp

Mashutka [201]

The answer is: No, because we also need to know the type of proportionality

In mathematics, we talk about proportionality when two variables are related and this relationship is that there is a constant ratio between them. There are two types of proportionality.

1. Direct Proportionality:

If there are two variables x and y, we can write the relationship between them as follows:

$y=kx$

So, by substituting the point in this equation we have that the constant of proportionality is:

$4=k(3) \\ \\ \therefore \boxed{k=\frac{4}{3}}$

2. Inverse Proportionality:

In this case, the relationship is:

$y=\frac{k}{x}$

So, the constant of proportionality is:

$4=\frac{k}{3} \\ \\ \therefore \boxed{k=12}$

As you can see, we have found two different values of the constant of proportionality. So, it is necessary to know the type of proportionality.

The population of Maricopa County has been increasing for the past few decades. In 2016, the Maricopa County population is appro

maria [59]

Answer: 3,965,481

Step-by-step explanation:

Given: In 2016, the Maricopa County population is approximately 3.817 million.

i.e. Initial population= 3.817 million =3,817,000

Of the population increases from the current population by 3.89 % over the next 5 years,

Population increased = 3.89% of 3,817,000

= 0.0389 (3817000)

= 148481.3 ≈ 148481

Population in 2021= 3,817,000 +148,481 =3,965,481

Hence, the population in 2021 = 3,965,481

Help!

nignag [31]

1) 8 + 4 = -5 + 7

12 = 2

FALSE

2) y = -11x + 4

(0, -7): -7 = -11(0) + 4 ⇒ -7 = 0 + 4 ⇒ -7 = 4 False

(-1, -7): -7 = -11(-1) + 4 ⇒ -7 = 11 + 4 ⇒ -7 = 15 False

(1, -7): -7 = -11(1) + 4 ⇒ -7 = -11 + 4 ⇒ -7 = -7 True

(2, 26): 26 = -11(2) + 4 ⇒ 26 = -22 + 4 ⇒ 26 = -18 False

Answer: C

3) Input Output

0 0

1 3

2 6

3 9

4 12

5 15

6 18

Rule: input is being added by 1, output is 3 times x

4) c = 65h

5) 2x = -6

$\frac{2x}{2} = \frac{-6}{2}$

x = -3

6) 8j - 5 + j = 67

9j - 5 = 67 added like terms (8j + j)

+5 +5

9j = 72

$\frac{9j}{9} = \frac{72}{9}$

j = 8

7) y = mx + b

-b -b

y - b = mx

$\frac{y - b}{x} = \frac{mx}{x}$

$\frac{y - b}{x} = m$

Help plz if your good at finding the area of the compound figure plz help if you don’t know the answer your not needed but if yo

spin [16.1K]

Answer:

96cm^2

Step-by-step explanation:

We can divide it into two rectangles: 7x8 and 10x(12-8), arriving at the solution of 7cm*8cm + 10cm*4cm = 56cm^2 + 40cm^2 = 96cm^2

We can also divide it into two rectangles: 12x7 + (12-8)x(10-7), arriving at 12cm*7cm + 4cm*3cm = 84cm^2 + 12cm^2 = 96cm^2

We could also divide it to one big rectangle and one "negative" rectangle of 10x12 and -8x(10-7), arriving at 10cm*12cm - 8cm*3cm = 120cm^2 - 24cm^2 = 96cm^2
