hi pls helpppppp. thank uuu :)

Answer:

x = -5 or 1/2

Step-by-step explanation:

From the question,

3x²+12x-7 = x²+3x-2

Collect like terms

3x²-x²+12x-3x-7+2 = 0

2x²+9x-5 = 0

Using factorization method to solve the quadratic equation

2x²+10x-x-5 = 0

(2x²+10x)-(x+5) = 0

2x(x+5)-1(x+5) = 0

(x+5)(2x-1) = 0

Either,

x+5 = 0

x = -5

or,

2x-1 = 0

2x = 1

x = 1/2.

Therefore,

x = -5 or 1/2

Answer:

x ≤ 2

(when graphed, closed circle on two, shaded to the left)

Step-by-step explanation:

3/4 x - 2/3 ≤ 5/6

Add 2/3 to both sides:

3/4x ≤ 5/6 + 2/3

3/4x ≤ 3/2

Divide by 3/4 on both sides:

x ≤ 3/2 ÷ 3/4

x ≤ 2

Hello There!

So for this problem we want to find the distance between two points

The y values of the given points are the same so all we have to do is subtract the highest x value from the lowest x value

5 - 2 = 3

so the distance between the two points is 3

Answer:

  110 stones

Step-by-step explanation:

Using your conversion factors, you get ...

  [tex]0.7\text{ T}\cdot\dfrac{1000\text{ kg}}{1\text{ T}}\cdot\dfrac{2.2\text{ lb}}{1\text{ kg}}\cdot\dfrac{1\text{ st}}{14\text{ lb}}=\dfrac{0.7\cdot1000\cdot2.2}{14}\text{ st}\\\\=\boxed{110\text{ st}}[/tex]

Additional comment

The exact conversion between kg and pounds is 1 lb = 0.45359237 kg. The number 2.2 is approximate, low by approximately 0.21%.

Answer:

294

Step-by-step explanation:

14 x 9 = 126

so the area of your rectangle is 126.

15 - 9 = 6

so 6 is the width, 14 is the height.

14 x 6 = 84

now you have to multiply is by 2, because there is still another Triangle on the other side.

84 x 2 = 168

Now you take 168 and 126 and add your areas, and you have found the complete area!

168 + 126 = 294

I hope this helps! :)

The second choice, 6(7x + 10)

Step-by-step explanation:

42x + 60 Simplify

Answer:

6(7x+10)

Step-by-step explanation:

Hello There!

We can find an equivalent expression by factoring

First we need to find the greatest common factor (GCF)

GFC - largest number that both numbers can be divided by

Lets write down all of the multiples of each number

42 - 42 and 1, 21 and 2, 13 and 3, 6 and 7,

60 - 60 and 1, 30 and 2, 20 and 3, 4 and 15, 6 and 10

Then we find the greatest common factor which would be 6

42x/6=7x

60/6=10

so we can conclude that an equivalent expression would be

6(7x+10)

Answer:

50272

Step-by-step explanation:

Okay how I solve these equations is I take the problem apart like this:

3142 = 3000 + 100 + 40 + 2

Now we multiply each number by 16:

3000 * 16 = 48000

100 * 16 = 1600

40 * 16 = 640

2 * 16 = 32

Then we add all the totals together:

48000 + 1600 + 640 + 32 = 50272

Hope this Helps ;)

Answer:

-6 and 7

Step-by-step explanation:

x is one number and y is the other

(1)-----------------    8x+5y=-13

(2)------------------  x+y= 1

first, let multiply both sides of (x+y=-1) by 8

(3)-----------------    8x+8y=8

lets subtract (1) from (3)

(8x+8y)-(8x+5y)=8-(-13)=3y

8-(-13)=3y ->  21=3y

y=7

lets plug in 7 into (2) for x

x+7=1

x=-6

the numbers are -6 and 7

The scatter graph for level of water in a dam on each day and date for one month type of data is most likely to suggest a linear association.

A scatter plot, like a scatter chart or graph, employs dots to represent the values of two numerical variables. The horizontal value represents the data from individual points. Hence, it is used to observe the relationships between variables.

The scatter plot can provide the values for the data set. The points can be of various sizes, colours, and forms. The information is presented in the form of points.

The values are represented on the vertical axis. The data association can be positive, negative, or neutral. A mosaic and a fluctuational diagram can be displayed on the scatter plot.

Thus, the plot which can be linear association form level of water in a dam on each day and date for one month

Answer:

Step-by-step explanation:

10% of 50 = 5

5% of 50 = 2.5

to get to 65 u do 5+5 = 10 so so far that is 20% but 20% only gets u to 60 so u add another 10% to reach 65

u have used 30% so the answer to yr question is 30%

The formula used to find the area of a triangle is

[tex] \frac{1}{2} b \times h[/tex]

so the area of the triangle is

[tex] \frac{1}{2} \times 8 \times 4[/tex]

because 8 is the base and 4 is the height of the triangle

Therefore the area of the triangle is 16

Answer:

The center of the circle is [tex]C(x,y) = (2, 3)[/tex].

Step-by-step explanation:

The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:

[tex]C(x,y) = \frac{1}{2}\cdot R_{1}(x,y)+ \frac{1}{2}\cdot R_{2}(x,y)[/tex] (1)

Where:

[tex]C(x,y)[/tex] - Center.

[tex]R_{1} (x,y)[/tex], [tex]R_{2} (x,y)[/tex] - Location of the endpoints.

If we know that [tex]R_{1} (x,y) = (-2,10)[/tex] and [tex]R_{2} (x,y) = (6,-4)[/tex], then the location of the center of the circle is:

[tex]C(x,y) = \frac{1}{2}\cdot (-2,10)+\frac{1}{2}\cdot (6,-4)[/tex]

[tex]C(x,y) = (-1, 5) + (3, -2)[/tex]

[tex]C(x,y) = (2, 3)[/tex]

The center of the circle is [tex]C(x,y) = (2, 3)[/tex].
