Square root property

Step-by-step explanation:

The given equation is :

[tex]x^2+6=31[/tex]

We need to write the most appropriated technique to solve the above equation.

Subtracting both sides of the above equation by 6 such that,

[tex]x^2+6-6=31-6\\\\x^2=25[/tex]

Now taking square root on both sides we get :

[tex]x=\sqrt{25}[/tex]

The square root property is used here, such that the value of x is :

[tex]x=\pm 5[/tex]

Answer:

500 milliliters or ml

Step-by-step explanation:

First, we find the amount of milk is in the measuring cup which is 350 ml  and then add 350 ml of milk to the 150 ml of tomato sauce to get 500 ml.

Hope it helped :)

The amount of soup made by Von is equal to 500 milliliters. Hence, option D is correct.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data given in the question,

Von mixes tomato sauce and milk to make soup.

Initially, the amount of tomato sauce added in the pot = 150 milliliters.

Then, milk is added that is in the measuring cup that is 350 milliliters.

So,

The total amount of soup made by him,

= 150 + 350

= 500 milliliters.

Answer:

Because the line doesn’t start at 0 and that shows that y is not proportional to x.

Step-by-step explanation:

That is all you have to write

A graph can show direct, inverse and joint proportions.

y is not directly proportional to x because the graph does not pass through the origin

From the graph, we can see that:

When x = 0, y > 0

i.e. y is greater than 0, when x equals 0

This means that, the equation of the graph is:

[tex]\mathbf{y = mx + b}[/tex], where b > 0

A proportional equation is represented as:

[tex]\mathbf{y = mx}[/tex]

Hence, y is not directly proportional to x because the graph does not start from the origin

Answer:

y=2x+11

Step-by-step explanation:

Slope is 2

y=2x+b

plug in (-3,5)

5=-6+b

b=11

y=2x+11

Answer:

y = 2x+11

Step-by-step explanation:

y = mx+b where m is the slope and b is the y intercept

We know the slope is 2

y =2x+b

We have a point (-3,5)

Substitute this into the equation

5 = 2(-3)+b

5 = -6+b

Add 6 to each side

5+6 = b

11 =b

The equation is

y = 2x+11

Answer:

4/25

Step-by-step explanation:

Total amount of marbles: 8 + 5 + 12 = 25

With 25 marbles, the probability of picking a red is: 12/25

After 1 red marble is removed, the probability of picking a black is: 8/24 = 1/3

Then, the probability of picking a red then a black marble if you do not replace the first marble is: 12/25 * 1/3 = 4/25

Answer:

x = 7

Step-by-step explanation:

We can use ratios to solve

3x-6            10

----------   = -------------------

12+(3x-6)        10+8

Simplifying

3x-6            10

----------   = -------------------

(3x+6)        18

Using cross products

18(3x-6) = 10(3x+6)

Distribute

54x - 108 = 30x +60

Subtract 30x from each side

54x-30x -108 = 60

24x -108 = 60

Add 108 to each side

24x = 60+108

24x = 168

Divide each side by 24

24x/24 = 168/24

x =7

Answer:

A is correct, B and C are not!

Step-by-step explanation:

2 ≥ y/5 -1 means 2 is greater than or equal to the number on other side

So try those answers (15, 20, and 25) as y

2≥ 15/5-1

2≥3-1

2≥2

True! So A, 15, works

2≥20/5-1

2≥4-1

2≥3

False! So B, 20, does NOT work!

2≥25/5-1

2≥5-1

2≥4

False! So C, 25, does NOT work!

Answer: The answer is A 17in2

Step-by-step explanation:

In the question it states that the triangles are congruent (both the same).

  first I found the area of the top orange triangle.

the formula to find the area of a triangle is [tex]\frac{1}{2} bh[/tex] (base times Height).

so I did  [tex]\frac{1}{2} 3.23* 5.12[/tex]  which gave me 8.27.

Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.

the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)

Answer:

y = 7/5x + 4

Step-by-step explanation:

use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.

(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

The graph is a linear and straight line so option (B) will be correct.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

Given graph is ;

y = 2x - 3

The slope of any function is given by;

dy/dx

So,

d(2x - 3)/dx = -2

Since the slope is constant that it will be a straight line and the straight line curve is a linear function because it has a degree of 1.

Hence "The graph is a linear and straight line".

Answer:

Infinite

Step-by-step explanation:

Here are a system of how two equations can be classified ;

• If the gradients are the same but the y-intercepts are different, the system has no solution.

• If the gradients are different, the system has one solution.

• If the gradients are the same and the y-intercepts are the same, the system has infinitely many solutions.

Here is the proof.

3y - 9x = -6

5y - 15x = -10

In

3y - 9x = -6

When x =1

y= 1

When x=3

y= 7

Gradient of 3y - 9x = -6

=∆y/∆x

= (7-1)/ ( 3-1)

=(6)÷ 2

= 3

5y - 15x = -10

When x= 1

y = 1

When x=3

Y=7

Gradient of 5y - 15x = -10

=∆y/∆x

= (7-1)/ ( 3-1)

=(6)÷ 2

= 3

Since the gradients are the same the system has infinitely many solutions.

Step-by-step explanation:

I'm not exactly sure what the question is, but I am assuming that it is , How many students were in the original class?

If you have 14 students in 3 classes, then you need to multiply each class by 14.
