Ummm how do you do this two questions?

Answer:

[tex](2x + 1)^{2} - 4x(x - 1) = 7 \\ (2x + 1)(2x + 1) - 4 {x}^{2} + 4x = 7 \\ 4 {x}^{2} + 4x + 1 - 4 {x}^{2} + 4x = 7 \\ 8x + 1 = 7 \\ 8x = 7 - 1 \\ 8x = 6 \\ \\ x = \frac{6}{8} \\ \\ x = \frac{3}{4} \\ \\ x = 0.75[/tex]

Answer:

63

Step-by-step explanation:

1/4 of 168 is 42 which is how many Boxes of Candy they sold

42 x 1.50 = 63

Answer:

From the sale of boxes of candy, the team made $63

Explanation:

We know that 3/4 of the sold items were chocolate bars. A fast trick to find 3/4ths, or 75%, of a number is to multiply it by 3 and divide by 4.

168 * 3 = 504

504 ÷ 4 = 126

Now, we do 168 - 126 to find the number of candy boxes.

168 - 126 = 42

So, the soccer team sold 42 boxes of candy. Since each box was $1.50, we just multiply

42 * 1.50 = 63

The soccer team made $63 dollars by selling candy boxes.

Note: This is just my way that I did quickly, there are many many other ways to do this. Try to find what's best for you.

Step-by-step explanation:

the slope (or gradient) of a line is the factor of x.

in our case here : 3

it is expressed as ratio y/x and represents the amount of units y changes (and via the sign in what direction), when x changes a certain amount of units (again, via the sign in what direction). like when going from a point 1 to a point 2.

so, here we have 3 = 3/1, and that means, when x changes by 1 unit to the right (positive), y changes 3 units up (positive).

the y-axis intercept is simply the point, where x = 0. clearly, any point with the x coordinate being unequal to 0 cannot be on the y axis.

so, here

y = 3×0 + 7 = 7

=>

the y-axis intercept point is (0, 7).

Answer:

[tex](-5, -5)[/tex]

Step-by-step explanation:

To reflect a point over the y-axis is the same as flipping the sign of the x-value of the point.

So, point L reflect is [tex](-(5)), -5)=\boxed{(-5, -5)}[/tex].

Answer:

y = 1/8

Step-by-step explanation:

Divide both sides by 4/5, 1/10 divided by 4/5; 4/5y divided by 4/5. In 4/5y divided by 4/5, the two 4/5s cancels out, leaving y alone. 1/10 divided by 4/5 equals to 1/8. Now you have, 1/8 = y, which is the same thing as y = 1/8. Therefore, the value of y is 1/8.

Answer: 1/8

Step-by-step explanation:

4/5y=1/10

*multiply both sides by 5, and you'll get

4y=1/2

*divide both sides by 4

y=1/8

Answer:

6

Step-by-step explanation:

Let the number be " n ".

4 times a number,

= 4n

The difference between 4 times a number and 6

= 4n - 6

The difference between 4 times a number and 6 is 18,

4n - 6 = 18

4n = 18 + 6

4n = 24

n = 24 / 4

n = 6

The value of "n" that satisfies the equation is n = 6.

Option B is the correct answer.

We have,

To solve the equation "The difference between 4 times a number and 6 is 18," let's define the unknown number as "n."

The difference between 4 times the number and 6 can be expressed as "4n - 6."

According to the given equation, this expression equals 18:

4n - 6 = 18

To solve for "n," we will isolate the variable by performing the necessary algebraic steps:

Add 6 to both sides of the equation:

4n - 6 + 6 = 18 + 6

This simplifies to:

4n = 24

Next, divide both sides of the equation by 4 to isolate "n":

(4n) / 4 = 24 / 4

This simplifies to:

n = 6

Therefore,

The value of "n" that satisfies the equation is n = 6.
