Answer:

x = -16/11

Step-by-step explanation:

28/(x+4)=11

28=11(x+4)

28=11x+44

11x=-16

x=-16/11

Answer: x=4

Step-by-step explanation:

28 divided by x+4=11

28 divided by x=7

28/7=4

Answer:

x = 17

Area = 10,362units²

Step-by-step explanation

Given the sides of the triangle

S1 = 9x+4

s2 = 8x-4

S3 = 4x+17

Perimeter of the triangle is the sum of all the sides

P = S1+S2+S3

374 = 9x+4+8x-4+4x+17

374 = 21x+17

21x = 374-17

21x = 357

x = 357/21

x = 17

Hence the value of x is 17

Area of the triangle is 1/2bh

A = 1/2bh

b is the base

h is the height

Let the base be 9x + 4 and height be 8x-4

b = 9x+4

b = 9(17)+4

b = 153+4

b = 157units

h = 8x-4

h =8(17)-4

h = 136-4

h = 132

Area = 1/2 * 157 * 132

Area = 157*66

Area = 10,362units²

Answer: 59/4 or 14 3/4

Step-by-step explanation:

151 3 /16  ÷ 10 1 /4

2419 /16  ÷ 41 /4    

2419/16 × 4/41  

2419 × 4 /16 × 41

9676 /656

Divide both sides by 164

9676 ÷ 164  / 656 ÷ 164

59 /4  = 14 3 /4

Answer:

y= -3/5x+4

Step-by-step explanation

Answer:

-6/-2=-18/-6=54/-18

=3

Step-by-step explanation: -3 is the correct answer. -2x-3=6, 6x-3=-18,

-18x-3=54

2x-7 = 11

7 goes to the other side

2x=11+7

2x = 18

x=18/2

x=9

7x + 1 = 22

1 goes to the other side

7x=22 - 1

7x=21

x=3

3x - 8 = 22

8 goes to the other side

3x = 22+8

3x=30

x=10

8x+5 = 45

5 goes to the other side

8x=40

x=40/8

x=5

Answer:

The absolute of x would be 15

For the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.

Given that, A figure of the intersecting lines is given where 3 lines intersect at the same point.

The angle can be defined as one line inclined over another line.

A line can be defined by the shortest distance between two points is called a line.

Here,
From the figure
∠1 = ∠4
∠2 = ∠5
So,
∠6 = ∠3
Now, from the option, the property hold is m∠1 + m∠3 + m∠5 = 180°. because m∠1 + m∠6 + m∠5 = 180°, or ∠6 = ∠3.

Thus, for the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.

Step-by-step explanation:

Answer: 3(2(8-2x4)+25divided by 5 )-(2(8 divided by 4x2)-7(7-2x3

The answer is 14

Step-by-step explanation:

We wish to express 3x - y = 1

in slope-intercept form.

3x - y = 1

=> y = 3x - 1

Slope of line = 3, therefore

Slope of parallel line is also 3.

We have y = 3x + c.

When x = 1, y = 7.

=> (7) = 3(1) + c, c = 4

Hence the answer is y = 3x + 4.

Answer:

Step-by-step explanation:

From the given information:

For the first 10 ratings, the average value is 75.

For maintaining the average of 84 ratings for the first 21st rating, we have:

Total rating for 21 units = 84 * 21 = 1764

For 10 units = 84 *10 = 840

Now, the initial 10 unit average = 75 * 10 =750

The first 10 unit + last 10 unit = 840 + 750 = 1590

The difference = 1764 - 1590 =174 unit

So, in the 14th rating, he has to go with 174 units.

Answer:

Problem 1: No

Problem 2: Yes

Step-by-step explanation:

Problem 1:

{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}

This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.

Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.

Problem 2:

{(0, 2), (3, 4), (-3, -2), (2, 4)}

In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.
