⸻⸻⸻⸻

⸻⸻⸻⸻

[tex]y-2 = \frac{2}{3} (x-x_1)\rightarrow y-2 = \frac{2}{3} (x-(-3))\rightarrow y-2=\frac{2}{3} (x+3)[/tex]

⸻⸻⸻⸻

The point in the equation should be: (-3, 2).

»»————-　★　————-««  

Hope this helps you. I apologize if it’s incorrect.  

The correct points of the line will be (-3,2).

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the point (3,2) is on the line y-2 = 2/3(x+ 3). Satisfy the equation with the given point and check.

y-2 = 2/3(x+ 3)

2-2 = (2/3)(3 + 3)

0 = 4

To make left hand side and right hand side equal the value of x coordinate should be -3.

y-2 = 2/3(x+ 3)

2-2 = (2/3)(3 + 3)

0 = 0

Therefore, the correct points of the line will be (-3,2).

Answer:

Step-by-step explanation:

[tex]y =\dfrac{-3}{4}x -6[/tex]

Multiply the entire equation by 4,

[tex]4*y=\dfrac{-3}{4}x*4 - 6*4\\[/tex]

4y = -3x - 24

Add 3x to both sides

3x + 4y = -24

Add 24 to both sides

3x + 4y + 24 = 0

Answer:

When x= 4, then f(x)= 13.

When x= g(x), then f(x)=g

When x= -15(x), then f(x)= -15

Answer: 14 cm

Step-by-step explanation:

Answer:

R=14 cm

total area= πr²

=22/7*196=616 cm²

r2= 3.5 cm

area of the small circles= 2*πr²=2*12.25*22/7=77 cm²

length of rectangle=3

breadth=1

area =lb=3 cm²

area of the small circles+area of rectangle=77+3=80 cm²

remaining area=616-80=536 cm²

Answer:

128 degrees

Step-by-step explanation:

38+90=128

Answer:

Understand unit rate. The unit rate is a special type of ratio in which the two separate measurements are compared and expressed as a quantity of one.

Look at the data. The problem must have two terms, and you must be asked to determine how much of one term exists per unit of the other term.

Rewrite the data as a division problem.

Step-by-step explanation:

Answer:

Well, you first want to find out what it is in decimal form, which in this case is 0.124. Then once you do that, you can convert it to an improper fraction, which would be 124/100, you then can simplify it to convert it into a mixed number, which lands you the final answer of 1 6/25 I hope this helps you! :)

Answer:

B) Graph of an Absolute Value Function

Step-by-step explanation:

A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input correspond with exactly one output.    

The given table in Option A) is not a function because there are two corresponding y-values for x = 3.

Option C is also not a function because the input value of x = -1 has two output (y-values): -11 and 5.

Option D is also not a function because the input value of 3 has two output values: -5 and 0.

Option B represents a function because each input value has exactly one corresponding output value.  A useful technique to use in determining whether a given graph represents a function is the Vertical Line Test.  If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

Attached is an edited screenshot of Option B, where it shows that each blue vertical line has its own corresponding point.  This means that the each line crosses the graph at most once. Therefore, the correct answer is Option B.

The modal represent the division is 6 ÷ 6/9 = 9.

One of the most fundamental operations in arithmetic is division, in which a larger number is divided into smaller groups with the same number of items. Dividing a large group into smaller groups so that each group has the same number of items is called division. In math, it is an operation that equalizes sharing and grouping.

Given the number line in figure,

shows the number is divided in 9 equal parts

1/9, 2/9, 3/9, ..........9/9

and from 0 to 6/9 parts are marked,

there are 6 parts in 0 to 6/9

the division model for equation is

6 ÷ 6/9

and division is 6 ÷ 6/9 = 9

Hence the division sentence is represented by the model is 6 ÷ 6/9 = 9.

Answer:

The answer is f(x)=2

Step-by-step explanation:

When the input is given it means that the x is substituted by that number.

so 3x3-7.

3x3-7

9-7=2.

The f of x is equivalent to 2.

Step-by-step explanation:

perpendicular means to cross at a right angle (90 degrees).

so, any line perpendicular to the x-axis is parallel to the y-axis.

and any line parallel to the y-axis has only a defining x value. all points on that line have the same x value (while any value for y from -infinity to +infinity is valid).

the y-axis itself is

x = 0

the specified point here has an x value of 4.

so, the line we are looking for is

x = 4

to point out : this is NOT a function, because for the same x value we get more than 1 valid y values.

Answer:

The water level in the glass decreases.

Step-by-step explanation:

Looking at these choices, you should think of the cycles and phases of matter. Water decreasing from a cup would most likely mean that it evaporated, which is a phase change. It is going from a liquid to a gas, which is water vapor.

The factors of the given trinomial are (3x-2)(x+5).

Trinomial is a polynomial having 3 terms. At least one variable and one operation (addition, subtraction, multiplication, division) must be present in an algebraic expression.

Given is a trinomial 3x²+13x-10, we need to factorize it,

So,

= 3x²+13x-10

To factorize a trinomial, we do find the product of the product of a and c (ax²+bx-c) and find its two factors so that we can add or subtract so that we can find the middle term (b) of the trinomial,

Here,

a = 3, c = 10

a × c = 30

Now,

15 and 2 are the factors of the 30, also 15 - 12 = 13 which is the middle term of the trinomial,

Therefore,

3x²+13x-10 = 3x²+15x-2x-10

= 3x(x+5)-2(x+5)

= (3x-2)(x+5)

Hence, the factors of the given trinomial are (3x-2)(x+5).

Answer:

4 students to deliver magazines and 6 students to deliver newspaper

Step-by-step explanation:

The minimum number of students needed is 6.

Given that, in one day students can deliver 850 newspapers and 1440 magazines. Each student can deliver either 25 newspapers or 60 magazines in 1 hour.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, in 1 hour a student can deliver 25 newspapers, so in 6 hours a student can deliver 25 × 6 =150

So, number of students = 850/150 = 5.66

≈ 6

Now, 60 × 6 =360

So, number of students = 1440/360 = 4

Therefore, the minimum number of students needed is 6.
