Im not good at coordinate graphs but I think the answer is the second one, sorry if I'm wrong!! :)

Answer:

[tex]1)xyz = y \\ xz = 1 \\ x = \frac{1}{z} \\ 2)s = 7zx \\ x = \frac{s}{7z} \\ thank \: you[/tex]

Step-by-step explanation:

1. xyz = y

[tex] = > x = \frac{y}{yz} [/tex]

[tex] = > x = \frac{1}{z} (ans)[/tex]

2. s = 7zx

[tex] = > x = \frac{s}{7z} (ans)[/tex]

Answer:

y= -x+2

Step-by-step explanation:

Using the equation, y = mx+b, you know you have to find the slope. Find the slope using two coordinate points, (-2,4) and (0,2).

Subtract 2-4/0+2 - the answer is -1. Your slope is -1 and the y axis is given so the equation is y=-x+2

Answer:

the answer is 1.65

Answer:

6

Step-by-step explanation:

Add up all the values, then divide by the total number of values--5 values, in this case.

(4+5+6+6+9)/5 = 30/5 = 6

The subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression of subtraction is,

E = 11.5−7.2

The expression in the form of addition will be converted by changing the sign of 7.2.

E= 11.5 - (-7.2)

E = 11.5 + 7.2

Therefore, the subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.

Answer:

D = 2/5 or 0.4

Step-by-step explanation:

3/2 = 5d - 1/2

move the terms

3/2 - 5d = -1/2

calculate the difference

-5d = -2

divide both sides by -5

2 = 2/5

Answer:

$819

Step-by-step explanation:

First we find the area of the wall so we multiply 13ft x 9ft.

13ft x 9ft = 117ft

We know each square foot is equal to $7. So now we multiply 117 x 7 to get the total cost.

117 x 7 = $819

Answer:

14

Step-by-step explanation:

5x + 2 + 48 = (180-120)+30 +30

5x+50 = 60+30+30

5x+50=120

5x=120-50

5x = 70

x = 70/5

x = 14

Answer:

74

Step-by-step explanation:

3 3/7 , 4 2/7, 5 1/7, .... 66

=> could be changed into :

24/7, 30/7, 36/7, ...... 462/7

let the numbers = n

462 = 24 + (n-1)(6)

462 = 24 + 6n -6

462 = 6n +18

6n=462-18

6n = 444

n = 444/6 = 74

Answer:

40°

Step-by-step explanation:

Since triangle ABC is identical to triangle A'B'C', it has the same measures of respective sides and angles, and ang A is therefore equal to angle A'.

After rotational transformation, the measure of angle ∠A' = 40°.

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.

For the given situation,

The diagram shows the two triangles.

Triangle ABC is the original triangle and A'B'C' is the triangle obtained after the rotation of -120°.

From the definition, in rotational transformation the size and shape of the figure stays exactly the same. Then the angle measures are also remains the same.

Thus the measure of angle A' is [tex]\angle A' = \angle A = 40[/tex]

Hence we can conclude that after rotational transformation, the measure of angle ∠A' = 40°.

Hey there! I'm happy to help!

Our question tells us that the number of packages is p and that the number of binders is b.

Each package is $3, so for every p we have, we will have 3 more dollars. So we have 3×p, which is written as 3p.

The same goes for binders. For every binder, we have 4 more dollars, so we have 4×b which is just written as 4b.

An expression is just a number sentence without an equal sign, so something like 1+1 or 7x². The variables are just the letters or symbols that represent an unknown quantity (so 7x² is a variable expression).

Our total cost is going to be the cost of our packages and our binders, so we combine the 3p and 4b we previously came up with, so our expression is 3p+4b.

Now, we can plug in our amounts of each thing into the equation. We will insert our 3 packages in plae of the p and our 8 binders in place of the b to find our cost.

In algebra, you can also write multiplication as a number outside of a number in parentheses so 4(2)=8 for example.

3(3)+4(8)

9+32

41

So, the total cost is $41.
