Answer:

your  cat will be 12 your friend will be either 16 or 24

Step-by-step explanation:

Friend is 12 years old and cat is 4 years old.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side.

Given,

Cat is 8 years younger than your friend

Let age of friend be x

then, age of cat be x - 8

But In 4 years, your friend will be twice as old as your cat

x + 4 = 2(x - 8 + 4)

x + 4 = 2x - 16 + 8

x + 4 = 2x - 8

-2x + x = - 12

x = 12

Age of friend = 12 years

Age of cat = 12 - 8 = 4 years

Hence, 12 years is age of friend and 8 years is age of cat.

Answer:

6

Step-by-step explanation:

We need to simplify this equation:

6.9 - 5 + 4.1

The reason why there is a negative sign in between 6.9 and 5 is that + and - become negative.

Answer:

the early bird special plate is 52

Step-by-step explanation:

Let us assume the early bird special be x

And, regualr price be y

Now the equations are

x + y = 93

7x + 9y = 733

Now multiply by 7 in equation (1)

7x + 7y = 651

7x + 9y = 733

Now subtract these two equations

-2y = 82

y = 41

x = 93  - 41

= 52

hence, the early bird special plate is 52

Answer:

Weight of baking soda in each container  = 2 pounds

Weight of sugar in each container = 4 pounds

Weight of flour in each container =  16 pounds

Step-by-step explanation:

As given,

Let the weight of baking soda in each container  = x pounds

Given that,

The weight of the sugar in each container is 2 times the amount of baking soda.

⇒ Weight of sugar in each container  = 2x

Also given,

There are 14 pounds more flour than baking soda in each container

⇒Weight of flour in each container = 14 + x

Now,

Given that each container with the three dry ingredients weighs  22 pounds.

⇒ x + 2x + 14 + x = 22

⇒4x + 14 = 22

⇒4x = 22 - 14

⇒4x = 8

⇒x = [tex]\frac{8}{4}[/tex] = 2

∴ we get

Weight of baking soda in each container , x = 2 pounds

⇒Weight of sugar in each container , 2x = 2(2) = 4 pounds

and Weight of flour in each container , 14+x = 14 + 2 = 16 pounds

As we have found the value of x is unique , so it can not be possible to have infinite solutions. So, the girl's claim is wrong.

Answer:

Step-by-step explanation:

Given functions f(x) and g(x). f(x) is:

Converted into vertex form, it is:

g(x) has vertex at (-2, -14), it's vertex form is:

Comparing f(x) and g(x) we see both have same x- coordinate of the vertex (x = -2).

Both have positive leading factors, therefore the vertex is their minimum point.

Function f(x) has vertex above the x-axis as y-coordinate of the vertex is positive. Hence no intersection with x-axis.

Function g(x) has negative y-coordinate of the vertex, so it has two intersections with x-axis.

Step-by-step explanation:

Answers:

Those y outputs are placed into the table in the order shown. For instance, -1 goes right underneath the '3'.

========================================================

Explanation:

Let's find the equation first. The function rule is "the output is 4 less than the input". So whatever the input x is, we subtract off 4 to get the output y.

This leads directly to the equation y = x-4

This is the same as saying y = 1x-4 which is in the form y = mx+b

m = 1 is the slope and b = -4 is the y intercept

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

Once we have the equation, we plug in the given input x values one at a time to find their corresponding y values.

For example, if x = 0, then,

y = x-4

y = 0-4

y = -4

So we have x = 0 pair up with y = -4. We write -4 underneath the 0 in the table given.

Then we write -3 under the "1" in the table because

y = x-4

y = 1-4

y = -3

And so on. Repeat this process until you get to x = 4.

You should have these ordered pairs
