What’s the value of x?

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:

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].

Answer:

16

Step-by-step explanation:

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:

6l², where l is the length of one side.

If the side is increased 10 times,

6(10l)²

=100 x6l²

The surface area increases 100 times. Thus, the new surface area is

272 * 100

= 27,200 sq in

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%

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:

the answer is D

Step-by-step explanation:

I can't really see the picture that well but I believe it's D because rational numbers are a part of irrational numbers.

Step-by-step explanation:

here's your solution

=> sum of ages of both A and B = 55

=> let the ratio be in x

=> now, ratio is 5x and 6x

=> a/q , 6x + 5x = 55

=> 11x = 55

=> x = 55/11

=> x = 5

age of A = 6*5 = 30 years

age of B = 5*5 = 25 years

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
