Step-by-step explanation:

slope is 4

Answer:

Final answer is x = -2

Step-by-step explanation:

-6x-3=9

add 3 to -3 and to 9 (we add 3 because its a negative)

9+3 becomes 12.

now we are left with -6x=12

divide on both sides, -6x divided by -6, and 12 divided by -6.

this leaves us with -2.

x= -2

Answer:

2(x - 7) = 2x - 14

Step-by-step explanation:

→ Expand out equation

2x - 14 = 2x - 14

→ Minus 2x from both sides

-14 = -14

Answer:

15u + 141 = 420

Step-by-step explanation:

So basically we are modelling how much the coach is spending. Each player is given a uniform and a basketball

We can use 'u' as the cost of a single uniform

We can use 'b' as the cost of a single basketball

Since there is 15 players we must give a ball and uniform to each so

15u + 15b = 420

The problem gives us the cost of each basketball: 9.40

so now 15u + 15(9.4) = 420

15u + 141 = 420

Answer:The other rational number= -18/7

Step-by-step explanation:

The product of the two rational numbers is -42/63.

One of the rational number=7/27

The other rational number whch can be called R can be gotten by diving the product by the rational numvber goven

R x  7/27   =-42/63.

-42/63 ÷  7/27=R

R=-42/63 X 27/7

R= -18/7

c = -4/3, -2

Step-by-step explanation:

3c^2+4c+8=-6c

3c^2+6c+4c+8=0

3c(c+2) + 4(c+2)=0

(3c+4)(c+2)=0

3c+4=0

Answer:

area is length times width, so multiply the length and the width together and youll find the answer is 50. so b

Step-by-step explanation:

The area of the figure which is composite of rectangle and triangle is 42.5 square meters

The area of Rectangle is length times of width.

Let us find the area of rectangle whose length is 7 m and width is 5 m

Area of rectangle =7×5

=35 square meters

Now we observe the figure there is right triangle whose base is 3m and height is 5m

Area = 1/2×3×5

=7.5 square meters

Total area is sum of rectangle area and triangle area

Total area = 35+7.5

=42.5 square meters

Hence, the area of the figure which is composite of rectangle and triangle is 42.5 square meters

Answer:

A=110.88

Step-by-step explanation:

Use the formula of a triangle- a=bxh/2

Then multiply by 4 since there are four equilateral triangles in the net

Given:

The figure of a triangle LMN.

P is the centroid of triangle LMN.

To find:

14. Find the value of PN if QN=30.

15. Find the value of PN if QN=9.

Solution:

We know that the centroid in the intersection of medians of a triangle and centroid divides each median in 2:1.

Since P is the centroid it means NQ is the median from vertex N. It means P divides the median NQ in 2:1. So, PN:PQ=2:1.

14. We have QN=30.

[tex]PN=\dfrac{2}{2+1}QN[/tex]

[tex]PN=\dfrac{2}{3}(30)[/tex]

[tex]PN=2(10)[/tex]

[tex]PN=20[/tex]

Therefore, the value of PN is 20 when QN=30.

15. We have QN=9.

[tex]PN=\dfrac{2}{2+1}QN[/tex]

[tex]PN=\dfrac{2}{3}(9)[/tex]

[tex]PN=2(3)[/tex]

[tex]PN=6[/tex]

Therefore, the value of PN is 6 when QN=9.

Given:

The three vertices of parallelogram are (0,6),(5,-4),(-1,-5).

To find:

The fourth vertex of the parallelogram.

Solution:

Consider the given vertices of parallelogram are A(0,6), B(5,-4), C(-1,-5).

Let the fourth vertex be D(a,b).

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

We know that the diagonal of parallelogram bisect each other. It means their midpoints are same.

Midpoint of AC = Midpoint of BD

[tex]\left(\dfrac{0+(-1)}{2},\dfrac{6+(-5)}{2}\right)=\left(\dfrac{5+a}{2},\dfrac{-4+b}{2}\right)[/tex]

[tex]\left(\dfrac{-1}{2},\dfrac{1}{2}\right)=\left(\dfrac{5+a}{2},\dfrac{-4+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{5+a}{2}=-\dfrac{1}{2}[/tex]

[tex]5+a=-1[/tex]

[tex]a=-1-5[/tex]

[tex]a=-6[/tex]

And,

[tex]\dfrac{-4+b}{2}=\dfrac{1}{2}[/tex]

[tex]-4+b=1[/tex]

[tex]b=1+4[/tex]

[tex]b=5[/tex]

Therefore, the coordinates of fourth vertex are (-6,5).

Answer:

Arithmetic sequence; common difference is 8.

Step-by-step explanation:

An arithmetic sequence increases or decreases by a fixed amount from term-to-term.

10 - 2 = 8

18 - 10 = 8

The next term will be 18 + 8 = 26, and so on.

Answer: 2/5

Step-by-step explanation:

Number of red bricks = 50

Number of yellow bricks = 50

Number of green bricks = 50

Number of blue bricks = 50

Number of orange bricks = 50

Total number of bricks = 250

The probability of choosing a red piece is 50/250 = 1/5. Also, the probability of choosing a yellow piece is also 1/5.

Therefore, the probability that he chooses a red or a yellow piece will be:

= P(red) + P(yellow)

= 1/5 + 1/5

= 2/5

Answer:

RT = 86

Step-by-step explanation:

Here, we want to find the value of RT

looking at the given triangle, we can deduce that the smaller triangle SPQ is half the measure of the bigger triangle SRT

what this mean is that we have to multiply the dimensions on SPQ by 2 to get the equivalent dimensions of similar sides in SRT

Thus, we have it that;

2(15x -17) = 23x -6

30x - 34 = 23x -6

30x -23x = -6 + 34

7x = 28

x = 28/7

x = 4

So, we make a substitution

for RT;

23x-6

= 23(4) - 6 = 92-6 = 86
