Solve for x. 6x^2−2=13

Answers

Answer 1

[tex]6 {x}^{2} - 2 = 13[/tex]
You add both sides by 2
[tex]6 {x}^{2} = 15[/tex]
[tex] \frac{ {6x}^{2} }{6} = \frac{15}{6} [/tex]
[tex] {x}^{2} = \frac{15}{6} [/tex]
[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{15}{6} } [/tex]

Rewrite the following equation in slope-intercept form. 6x − 14y = -3 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:
y = (3/7) x + (3/14)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
6x - 14y = -3

To get in the slope-intercept form, we need to isolate the y as follows:
6x - 14y = -3
14y = 6x + 3
y = (6/14)x + (3/14)
y = (3/7) x + (3/14)

Hope this helps :)

Y=0
6x = -3
X= -2

X=0

victor has the map scale missing.he knows the distance from the lake to the youth center is 8 miles. on the map they are 2in. apart. what is the scale for victors map

Answers

The correct scale is 1 in = 4 mi.

Explanation:

The scale tells us what a given measurement on the map equals in real-life distance.

The measurement on the map that we have is 2 inches, and it equals 8 miles:

2 in = 8 mi

This can also be written as 2/8. This fraction can be simplified, since both 2 and 8 are divisible by 2; it will simplify to 1/4. This is the same as
1 in = 4 mi.

Answer:

The correct scale is 1 inch = 4 miles.

Step-by-step explanation:

Map scale is defined as the ratio between the marked distance on a map to the corresponding distance on the ground.

Here, it is given that the measurement on the map is 2 inches, and it equals to 8 miles; so 2 inches = 8 miles

Simplifying this we get:

1 inch = 4 miles.

Hence, the scale is 1 inch equals 4 miles.

How do I find the prime factorization of 40? And what is prime factorization?

Answers

Prime factorization is a way of showing which prime numbers (numbers that can only be divided by one and itself) can go into a number. For instance, the prime factorization of 4 would be 2 x 2. Two can only be divided by one and itself, so it is a prime number, and 2 x 2 = 4. For larger numbers, divide by a prime number until the number that is being divided is a prime number. Each divisor will be used as part of the prime factorization. The final dividend will also be used. Add the dividend, order each divisor from least to greatest, and then you're done. Therefore, the prime factorization of 40 would be 2 x 2 x 2 x 5.

Final answer:

Prime factorization is finding the prime numbers that multiply to create the original number. The prime factorization of 40 is 2³ × 5.

Explanation:

Prime factorization is the process of breaking down a composite number into the prime numbers that, when multiplied together, give the original number. To find the prime factorization of 40, you would start by finding two numbers that multiply to give you 40. You could start with 4 × 10. Since 4 is not a prime number, it can be further broken down into 2 × 2. The number 10 can also be broken into prime factors 2 × 5. Therefore, the prime factorization of 40 is 2 × 2 × 2 × 5, or 2³ × 5.

Hey there!

To solve this, you can divide 1 1/2 and 3/4 . . .

1 1 /2 = 3/2
3/4 = 3/4

3/2 divided by 3/4:

3 x 4 = 12
2 x 3 = 6

Lin needs 2 cups of raspberries for the whole cake.

The number 50 is no more than a number h times 2

Answers

That depend what #uou plug in for the variable h

The statement 'The number 50 is no more than a number h times 2' is an algebraic inequality stating that 50 is less than or equal to 2h. To solve for h, we divide 50 by 2, yielding h must be greater than or equal to 25.

The question "The number 50 is no more than a number h times 2" relates to a basic algebraic concept where we represent numbers or quantities using variables. The statement can be translated into an inequality that states 50 is less than or equal to 2 times a number h, or mathematically, 50 <= 2h. This could be solved for h by dividing both sides of the inequality by 2, resulting in h >= 25.

Which equation BEST represents the line of best fit for the scatterplot? A) y = x + 2 B) y = x + 1 C) y = x - 2 D) y = 2x + 1

Answers

Answer:

y=x+2 is the right answer

Step-by-step explanation:

Equation A best represents the line of best fit for the scatter plot. Option A is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

From option 1;

y= x+2

At,x=0 y=2

At,y=0 x=-2

The equation satisfy the graph in the best possible way. So that equation A best represents the line of best fit for the scatter plot.

Hence, option A is correct.

Answers

Statement A is the false one.

f(x)=(2x+1)(3x-2)
The zero product property says that f(x)=0 when either (2x+1)=0, or (3x-2)=0, or both.
We also know that the zeroes of an equation are the values of x when f(x)=0.
So f(x)=0 when (2x+1)=0 or (3x-2)=0 => x=-1/2 or when x=2/3. which are the roots of f(x).

A. the y-intercepts have nothing to do with the zeroes of f(x).
B. By definition of zero of a function, it is true that the values of x when f(x)=0 are the zeroes of f(x).
C. The zeroes of f(x) are the same as the ones calculated above, so it is true.
D. The x-intercepts of the lines are basically the zeroes of the function f(x), as explained above. So the statement is true.

From our diagram we can see that angle HED equals to angel GED and angle GDE equals to angel HDE.

Two triangles are similar if the corresponding angles are equal, so their corresponding sides will be in equal ratio.

Upon setting ratios of corresponding sides of our triangle equal we will get,

[tex]\frac{EG}{GD} =\frac{EH}{HD}[/tex]

[tex]\frac{99.2}{62} =\frac{112}{(x+2)}[/tex]

Now we will use cross multiplication to solve our equation,

[tex]99.2(x+2)=112\cdot 62[/tex]

[tex]99.2x+198.4=6944[/tex]

[tex]99.2x=6944-198.4[/tex]
