Answer:

7/3

Step-by-step explanation:

y2-y1/x2-x1

-2-(-9)/6-3 = -2+9/3 = 7/3

The value of x for the given equation is -3/2.

The given equation is 5 = -2(x-1).

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Here, 5 = -2(x-1) can be written as 5=-2x + 2.

Now, 5-2=-2x

⇒ 3=-2x

⇒ x=-3/2

Therefore, the value of x for the given equation is -3/2.

Answer:

3

Step-by-step explanation:

The rate of change is just another way of saying slope.

The slope of a line is it’s rise over run.

We can see here that every time x increases by 1, y increases by 3. (This is where the triangle comes in handy).

Rise:3

Run:1

[tex]\frac{3}{1}=3[/tex]

So the rate of change is 3.

Answer:

The difference between the times is just 6.09

Step-by-step explanation:

Here, we are interested in finding the difference between the times when two athletes finished their races.

While one finished at 24.53, the other finished at 18.44; So the difference between the two will be calculated by subtracting the time which was less from the time which was more;

Mathematically, that would be 24.53 - 18.44 = 6.09

Answer:

If the absolute value expression is not equal to zero, the expression inside an absolute value can be either positive or negative. So, there can be at most two solutions. Looking at this graphically, an absolute value graph can intersect a horizontal line at most two times.

Such a ray that divides an angle into two equal angles is called an angle bisector.

Likewise, two rays that divide an angle into three congruent angles are called angle trisectors. Figure %:

An angle bisected and trisected On the left, angle ABC is bisected by the ray BD.

Answer:

[tex]d=\frac{f+4}{3}[/tex]

Step-by-step explanation:

3d - 4 = f

add 4 to both sides

3d = f + 4

divide both sides by 3

d = f/3 + 4/3

Answer:

The answer is D, -11 degrees.  

Step-by-step explanation:

Angle RQP is total sum of angles RQU, (96 + x) and UQP, (x + 57).  

Angle RQP = 131.  

(96 + x) + (x + 57) = 131

153 + 2x = 131

2x = -22

x = -11.  

Therefore, answer is -11 degrees.

Answer:

7:21   For every student wearing a blue shirt, there were 3 students wearing red shirts.

Step-by-step explanation:

If there are 28 students and 7 are wearing blue shirts then the number of students wearing red shirts is 28 - 7 = 21 so 21 students are wearing red shirts.

That means the ratio of blue shirts to red shirts is 7:21

That also means that for every student wearing a blue shirt, 3 were wearing a red shirt.

We get this because 21/7 = 3  and 7/7 = 1

Answer:

70

Step-by-step explanation:

Solve any pre-algebraic equation with inverse operations:

-7 = y/-10

multiply both sides by -10

-7 * -10 = y

now simplify:

remember that multiplying two negatives with result in a positive

70 = y

[tex]\frac{5(9-x)}{3} < 11 - 1[/tex]

[tex]\frac{5(9-x)}{3} < 10[/tex]

5(9-x) < 10*3

5(9-x) < 30

9-x < 30/5

9-x < 6

-x < 6 - 9

-x < -3

x < 3

Answer:

y= 1/4x + 8

comparing with

y= mx + c

slope = 1/4

for y intercept x=0

y=8

Step-by-step explanation:

The slope of the line is 1/4, The y-intercept is 8.

In the equation y = (1/4)x + 8, the coefficient of x is 1/4. This coefficient represents the slope of the line.

Therefore, the slope of the line is 1/4.

The equation is in the form y = mx + b, where m represents the slope and b represents the y-intercept.

In this equation, the y-intercept is the value of y when x is 0. By substituting x = 0 into the equation, find the y-intercept.

y = (1/4)(0) + 8

= 0 + 8

= 8

Hence, the y-intercept is 8.
