help me and the 1st 2 answer will get brainliest and i need asap im in the test

Answer:

A.)

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

21 - (-5)     A negative minus a negitive turns into a +

21 + 5 = 26

A.  -21 + 5 = -16      NO

B.    21 - 5 = 16   NO

C. 21 + 5 = 26    YES

D. -21 - 5 = -26    NO

Answer:

C

Step-by-step explanation:

When subtracting a negative, the two negatives cancel out. The rule is that two like signs become positive.

Therefore, +(+) =+ and -(-) = +  

So, the equation would be 21 + 5.

to get the exponent number, you count however many times the number is being multiple by itself

Answer: Solving  we get x=7 and y= -3

Step-by-step explanation: We need to solve the following systems of equations:

Let:

Adding eq(1) and eq(2)

So, value of x=7

Putting value of x in eq(1) to find value of y:

So, value of y = -3

So, Solving  we get x=7 and y= -3

Answer: 3sqrt(2)

Step-by-step explanation:

d = sqrt[(3-0)^2 + (4-1)^2]

d = sqrt[9+9]

d = sqrt(18) = 3sqrt(2)

Answer:

3

Step-by-step explanation:

The slope of the chart, (the change of y over x) is 3

Answer:

What are the steps for using a compass and straightedge to construct a line through point X that is parallel to line r? Drag the steps and drop them in order from start to finish. Use the straightedge to draw a line s that passes through X and intersects line r. Label the point of intersection as point Y.

Step-by-step explanation:

Answer:

1. Use the straightedge to draw a line s that passes through X and intersects line r. Label the point of intersection as point Y.

2. Place the point of the compass on point Y and draw an arc that intersects lines r and s. Label the intersections as points M and N.

3. Without changing the width of the compass opening, place the point of the compass on point X and draw an arc that intersects line s. Label the intersection as point P.

4. Place the point of the compass on point M and open it to width MN.

5. With the compass opening set to width MN, place the point of the compass on point P and draw an arc that intersects the arc that was drawn from point X. Label the intersection of the arcs as point Z.

6. Use the straightedge to draw XZ.

Step-by-step explanation:

Verified correct with test results!!

Given:

[tex]y=x^2+6x-1[/tex]

[tex]\dfrac{x}{r}=-3[/tex]

To find:

The given equation in terms of r if [tex]\dfrac{x}{r}=-3[/tex].

Solution:

Given that,

[tex]\dfrac{x}{r}=-3[/tex]

[tex]x=-3r[/tex]

We have,

[tex]y=x^2+6x-1[/tex]

Substitute x=-3r in the above equation.

[tex]y=(-3r)^2+6(-3r)-1[/tex]

[tex]y=9r^2-18r-1[/tex]

Therefore, the required equation in terms of r is [tex]y=9r^2-18r-1[/tex].

It can be inferred that Broadway shows with higher ticket prices tend to be more popular and offer more performances.

Now,

Since,  More popular shows have higher ticket prices and offer more performances.

Hence, Based on the information given, the best explanation for the relationship between ticket prices and the number of performances is that more popular shows tend to have higher ticket prices and offer more performances.

This is supported by the strong, positive relationship indicated by the value of r being 0.763, which suggests that as ticket prices increase, the number of performances tends to increase as well.

Therefore, it can be inferred that Broadway shows with higher ticket prices tend to be more popular and offer more performances.

#SPJ1

Step-by-step explanation:

let x be the number of adults and y the number of childrens

x+y=548 people because thats the whole number of sold tickets

and

6.50*x+3.50*y=2881 dollars in total

let separate x from the first formula

x=548-y

and replace it at the second equation

6.50*(548-y)+3.50y=2881

6.50*548-6.50y+3.50y=2881

3562-3y=2881

3y=681

y=227

so x=548-y=548-227=321

there were sold 321 adult tickets and 227 child's tickets.

Answer:

y = 3x + 5

Step-by-step explanation:

The linear formula follows this general form: y = mx + c

Hence, to put 5-y=-3x in standard form, you would rearrange it

-y = -3x - 5

y = 3x + 5

Answer:

3x-y=-5

Step-by-step explanation:

standard form is Ax + By = C

5-y=-3x      move the y to the other side by adding it to the -3x

-3x+y=5     The x cant be negative so switch all the signs

3x-y=-5

Answer:

Should be E.

Step-by-step explanation:

if u add and if u subtract 4 from both sides u get 1x=19,divide frmo both sides and x=19

Answer:

14.45

Step-by-step explanation:

Answer:

0.04 or 1/25

Step-by-step explanation:

If x = -2, then the equation is f(-2) = 5^-2

5^-2 is 0.04 so,

f(-2) = 0.04 or 1/25
