function y = 4x + 7 models the average number of cats at the animal shelter, where x is the number of days after July 1. After how many
days is the average number of cats and dogs at the shelter the same?

Option C is correct ✔.

Answer: There's no image there, but I assume it's because they are behind the 0.

Step-by-step explanation: The range of real numbers goes from - infinity to positive infinity. The 1/4 and 3/8 that are on the number line are probably behind the 0, indicating that they are negative numbers. I don't know if what I'm saying makes sense in the context of the problem (since you didn't provide a picture).

Answer:

x=20

Step-by-step explanation:

we see that the connection between y and x is that y is always 1/2 as much as x.

Answer: x=1

Step-by-step explanation: 6x+24=30

6x=6

x=1

Answer:

x=1

Step-by-step explanation:

distribute 6 into (x+4). 6x+24=30

Subtract 24 from its place, cancel it, and subtract it from 30. 6x=6

Answer:

x=10 y=7

Step-by-step explanation:

1) 2(5x-5)=(6x+50)

2) 10x-10=6x+50

3) 4x-10=50

4) 4x=40

5) x=10

1) 7y-9=5y+5

2) 2y-9=5

3) 2y=14

4) y=7

Answer:

x=15, y=7

Step-by-step explanation:

Set up each equation to each angle's vertical angle.

Solve for x.

2(5x-5)= 6x+50

10x-10=6x+50

x= 15

Solve for y.

5y+5= 7y-9

y=7

Answer:

Area: 40cm^2

Perimeter:24cm

Step-by-step explanation:

Area: First of all, you can see that the missing height of the shape is 3cm. By adding 4 and 3, you get 7. Then, by multiplying 7 and the length of the shape (6cm), you get 42cm^2. After that, you have to multiply 2cm and 3cm to get the blank area in the bottom right corner to get 6cm^2. Finally, you can subtract 42cm^2(the whole area) by 6cm^2 (the blank area) to get 40cm^2.  

Perimeter: Okay! To get the first missing measurement (the one on the left), you have to imagine 4cm being moved to that side. 3cm is parallel to the missing blank space under the 4cm. This means you have to get 7cm (you add 4 and 3). To get the other missing measurement (bottom of the shape) you must see that 6cm would be parallel to the bottom. Since 2cm is also parallel to the bottom, you would have to subtract 2 from 6 to get the bottom of the shape's length, which is 4. Finally, you would have to add 6, 4, 3, 2, 4 and 7 together to get 24cm.

Answer:

The lime represents 0 im pretty sure.

I believe so because on the bottom left it says that lime + cherry = cherry, which could only mean that the lime has a value of 0, otherwise the sum would be different.

Answer

D

Step-by-step explanation:

D is correct because 1,400-400= 1,000

so he can only consume 1,000 more calories so 1,200 will cause him to go over 2,000

Answer:

El área de un cuadrado de lado L es:

A = L*L

Y sabemos que si el cuadrado menor tiene lado de largo L, entonces el cuadrado mayor tiene lado de largo 2*L - 1ft

Área menor = L*L = L^2

Área mayor = (2L - 1ft)*(2L - 1ft)

El área total es igual a la suma de ambas áreas:

121 ft^2 = L^2 + (2L - 1ft)*(2L - 1ft) = L^2 + 4*L^2 - 2ft*L + 1ft^2

Ahora podemos resolver esto para L.

121 ft^2 = 5*L^2 - 2ft*L + 1ft^2

0 = 5*L^2 - 2ft*L - 120 ft^2.

Usando la formula de Bhaskara, las soluciones son:

[tex]L = \frac{2ft +- \sqrt{(2ft)^2 - 4*5*(-120ft^2)} }{2*5} = \frac{2ft +- 49ft}{10}[/tex]

Las dos soluciones son:

L = (2ft + 49ft)/10 = 51ft/10 = 5.1ft

L = (2ft - 49ft)/10 = -4.7 ft

Como estamos hablando de el largo de algo, la única opción que tiene sentido es la positiva.

Entonces el largo de los lados del cuadrado menor es L = 5.1 ft

El largo de los lados del cuadrado mayor es M = 2*5.1ft - 1ft = 9.2ft

Answer:

All real numbers

Step-by-step explanation:

Answer:

C) all real numbers

Step-by-step explanation:

4(a + 3) = 12 + 4a

open the parenthesis

4*a + 3*4 = 12 + 4a

4a + 12 = 12 + 4a

subtract 4a from both sides of the equation

12 = 12

since 12 = 12 regardless of what x is the solution is all real numbers

Answer:

-3g-4

Step-by-step explanation:

Let's simplify step-by-step.

−2g+7−(g+11)

Distribute the Negative Sign:

=−2g+7+−1(g+11)

=−2g+7+−1g+(−1)(11)

=−2g+7+−g+−11

Combine Like Terms:

=−2g+7+−g+−11

=(−2g+−g)+(7+−11)

=−3g−4

Answer:

6g

Step-by-step explanation:

ll + g = 11g

-2g + 7 = 5g

11g - 5g = 6g
