How do I do this question folks?

horsena [70]

Answer:

Correct answer: B

Step-by-step explanation:

Syntax: in piecewise functions such as the one attached, the "if:" section shows the domain, or x-axis values which that function pertains to.

In the graph, you can see that the graph is defined for $-3\leq x < 1$ (not-including 1 because there is an open hole there, indicating it is not part of the domain), and $2\leq x\leq 4$ .

Now that we know the domain, we can attach it to the graphs that lie on those domains.

We see that the leftmost line appears to have a positive slope and a negative y-intercept, and that the second line should have a positive y-intercept and a negative slope.

At this point, you can just start crossing off answers that don't meet this criteria.

Cheers!!

The cost of three tickets to a movie is at least $20. Select an inequality that represents the cost x (in dollars) of each ticke

SVETLANKA909090 [29]

Answer:

$x\geq \$6.67$

Step-by-step explanation:

Let

x------> the cost of each ticket

we know that

$3x\geq 20$ ----> inequality that represent the situation

solve for x

Divide by 3 both sides

$x\geq 20/3$

$x\geq \$6.67$

A boy makes a cuboid of plasticine of sides 5cm, 2cm, 5cm. How manny such cuboids will he need to form a cube?

ruslelena [56]

Answer:

Step-by-step explanation:

L.C.M. of 5,2=10

so it should be of dimensions 10×10×10

it should have 5 cuboids in first row.

then it will make a cuboid 5×10×5

5 cuboids in the second row on top of first row .

Then it will make 5×10×10 cuboid

To make 10×10×10

double the cuboids to make the length=10 and height=10..

so in all 20 cuboids are needed.

2 rows of 5 cuboids on the floor and 2 rows of 5 cuboids on the top.

in all 10 cuboids of dimensions 5×2×5

so 9 more cuboids are needed to make a c
