Do you guys know the answer?

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: y = 800

Step-by-step explanation:

3(y+200) = 3000

y+200 = 1000 (dividing 3 from both sides)

y = 800

Answer and Explanation

This is because they are both the same opposite number, and you are adding.

But, if it was, [tex]\frac{64}{5}+\frac{64}{5}[/tex] then it would be [tex]25.6[/tex] or [tex]\frac{128}{5}[/tex].

So, the answer is 0.

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:

SinC = 7/25

CosC = 24/25

TanC = 7/24

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:

27

Step-by-step explanation:

The answer is 27, because 9 x 3 = 27 and the smallest number that is the same is 27.

Hope this helps!

Answer:

27

Step-by-step explanation:

LCM is the least common multiple of one or more numbers. we can find this by finding the factors of 9 and 27.

9, 18, 27, 36, 45, 54

27, 54, 81, 108

since 27 is the smallest factor of both 9 and 27, it is the least common multiple.

[tex]3 \div 5 - 1 \div 3 = 9 - 5 \div 15 \\ = 4 \div 15 \\ \\ 2 \div 5 \times 5 \div 6 = 2 \div 6[/tex]

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:

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

Answer:

the  percentage of the ramon earnings spent on electricity is 3.17%

Step-by-step explanation:

The computation of the percentage of the ramon earnings spent on electricity is shown below:

= Pays for electricity ÷ earnings per month

= $53 ÷ $1,670

= 3.17%

Hence, the  percentage of the ramon earnings spent on electricity is 3.17%

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
