(3z+1)+5+7z) Step by step explanation needed

Answers

Answer: 10z + 6

Step-by-step explanation:

this is a short problem.. sometimes you would need to distribute, but since there is no number in front of parenthesis you can just get rid of them

that gives you: 3z + 1 +5 + 7z

now from here we combined liked terms

7z + 3z = 10z

1 + 5 = 6

so that gives you: 10z + 6

Answer:

an = 6n - 18

Step-by-step explanation:

a3 = 0, a4 = 6, a5 = 12, a6 = 18, a7 = 24

a3 = a + 2d

a4 = a + 3d

a + 2d = 0 (1)

a + 3d = 6 (2)

Subtract (1) from (2) to eliminate a

3d - 2d = 6 - 0

d = 6

Substitute d = 6 into (1)

a + 2d = 0 (1)

a + 2(6) = 0

a + 12 = 0

a = -12

nth term,an = a + (n - 1)d

= -12 + (n - 1) 6

= -12 + 6n - 6

= 6n - 18

an = 6n - 18

HELP ME PLZ !!! IT'S ALGEBRA

Answers

Answer:

x = - 8/23

y = 40/23

Step-by-step explanation:

-5x- y = 0

and

-8x+3y = 8

The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.

-5x-y = 0

-y = 5x

y = - 5x

Now you can take this y value and plug it into the section equation.

-8x + 3(-5x) = 8

-8x - 15x = 8

-23x = 8

x = - (8/23)

Once you get the x value you can plug it back into equation one to get y's value

-5*-(8/23)  - y = 0

40/23 - y = 0

y = 40/23

y = negative StartRoot x minus 5 EndRoot + 3
y = negative StartRoot x + 5 EndRoot minus 3

Answers

Answer:

The function that has a domain of 'x' greater-than-or-equal-to 5 and a range of 'y' less-than-or-equal-to 3 is;

[tex]y = -\sqrt{x - 5} +3[/tex].

Step-by-step explanation:

The domain of a function are the possible 'x' values of the function

The range of a function are the possible 'y' values of the function

The given possible functions are;

1) [tex]y = \sqrt{x - 5} +3[/tex]

The range of values for the above function are;

Domain; x ≥ 5

Range; y ≥ 3

2) [tex]y = \sqrt{x + 5} -3[/tex]

The range of values for the above function are;

Domain; x ≥ -5

Range; y ≥ -3

3) [tex]y = -\sqrt{x - 5} +3[/tex]

The range of values for the above function are;

Domain; x ≥ 5

Range; y ≤ 3

4) [tex]y = -\sqrt{x + 5} -3[/tex]

The range of values for the above function are;

Domain; x ≥ -5

Range; y ≤ -3

Therefore, the required function is the third function, [tex]y = -\sqrt{x - 5} +3[/tex].

Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis. What are the coordinates of M'?

Answers

Given:

Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis.

To find:

The coordinates of M'.

Solution:

We have, M(2, -1) .

If a  figure reflected over the y-axis then

[tex](x,y)\to (-x,y)[/tex]

Using this rule, we get

[tex]M(2,-1)\to M'(-2,-1)[/tex]

Therefore, the coordinates of point M' are (-2,-1).

Answers

We want to find the graph of a system of inequalities. We want to select the correct option, but sadly is really hard to interpret the given text, so I will add a graph of the system at the end.

The system is:

y ≤ -3x + 1y ≤ (1/2)*x+ 3

To graph these we first need to graph the two lines:

y =-3x + 1

Is a line with a negative slope that passes through the y-axis at y = 1.

Because here we have y ≤ -3x + 1 we know that y must be equal or smaller than the line, thus we need to shade below the line, and because y can be equal to any value in the line we need to use a solid line.

For the other equation:

y = (1/2)*x+ 3

We have a positive slope and this line intercepts the y-axis at y = 3.

Similar as before, here we have y ≤ (1/2)*x+ 3 so the shaded area will be below the line and the line must be solid.

With this in mind, we can graph the system, and you can see it below:
