WILL GIVE BRAINLIEST ‼️ The graph represents the piecewise function:

Answers

Answer:

[tex]f(x) = \left \{ {{x + 3} \quad \text{if} \ -3 \leq x < -1\atop {5} \quad \text{if} \ -1 \leq x \leq1} \right.[/tex]

Step-by-step explanation:

You can find the first function if you know the general form of a line:

[tex]y = mx + b[/tex]

where [tex]m[/tex] is the slope and [tex]b[/tex] the intercept point with the [tex]y[/tex]-axis.

So in the first case the slope is 1 because the next formula

[tex]m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2-0}{-1+3} = 1[/tex]

And you can find the interception point if extend the line, then in our case is  3.

So the function is:

[tex]f(x) = x + 5[/tex]

In the other case is constant function that's mean that the function has the next form

[tex]f(x) = k[/tex]

Where [tex]k[/tex] is a constant.

So you only have to observe what is the value for each point in the interval, in this occasion is 5.

So the final answer is:

[tex]f(x) = \left \{ {{x + 3} \quad \text{if} \ -3 \leq x < -1\atop {5} \quad \text{if} \ -1 \leq x \leq1} \right.[/tex]

Solve by elimination Solve by elimination or substitution: 4x + 2y = 6 and x - 3y = 5

Answers

Step-by-step explanation:

since we need to multiply only one equation with something, elimination might be a good method here. we bring both equations to 4x terms and then subtract the second from the first equation :

4x + 2y = 6

- 4x - 12y = 20

0 14y = -14

y = -1

Dan received 64 dollars for his birthday. He went to a sporting goods store
and bought a baseball glove, baseball, and bat. He had 31 dollars left over,
how much did he spent on the baseball gear?

Answers

Answer:

the answer is 33 bucks because you have subtract the 64 -31 =33

He started with a total of $64 and $31 remained after his expenses.

We can create an Algebraic equation to represent the scenario. The variable “x” is equal to how much of his birthday money he spent.

64-x=31 [Equation]

64-64-x=31-64 [Subtract 64 from both sides to cancel it out and isolate x]

-x=-33 [Simplification after subtraction]

-x/-1=-33/-1 [Divide by -1 on both sides to cancel it out and solve for x]

x=33 [Defined Variable]

*Recall that “x” is equal to his expenses.

Therefore, Dan spent $33 of his $64.

We can check this because 64-33=31.

How many different 3 topping pizzas can be made if 10 different toppings are available?

Answers

Assuming you can’t use the same topping twice,
10 x 9 x 8 = 720

9514 1404 393

Answer:

  120

Step-by-step explanation:

We assume the order of the toppings does not matter. Then the number of interest is the number of combinations of 10 toppings taken 3 at a time. That is given by ...

  10C3 = C(10, 3) = 10!/(3!(10 -3)!) = 10·9·8/(3·2·1) = 120

120 different 3-topping pizzas can be made if 10 toppings are available.

Additional comment

If order matters, then 10 choices can be made for the first topping, 9 for the second, and 8 for the third, for a total of 10×9×8 = 720 different pizzas.

The number of baskets with 12 piece of  fruit is 15.

The number of baskets with 15 pieces of fruit is 45.

Percentage is the fraction out of a number expressed as a number out of hundred. The sign used to represent percentages is %.  

In order to determine the number of baskets that have 12 pieces of fruits and 15  pieces of fruits, multiply the given percentages by the total number of fruit baskets.

Number of baskets with 12 piece of  fruit: 25% x 60 = 0.25 x 60 = 15

Number of baskets with 15 pieces of fruit: 75% x 60 = 0.75 x 60 = 45
