Let x be the number.
The equation would be: 5 (2x - 11) = -25
Multiply 2x - 11 by 5 so that it is 10x - 55
Now, move the -55 to the other side of the equation so 10x = -25 + 55
Subtract so 10x = 30
Now divide 30 by 10 to find x.
x = 3

Option C: \frac{4}{5} is the slope of the line

Explanation:

The line passes through the points (3,-1) and (-2,-5)

We need to find the slope of the line.

The slope can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Where the coordinates (x_1,y_1) and (x_2,y_2) are (3,-1) and (-2,-5)

Let us substitute the points in the formula

Thus, we have,

m=\frac{-5-(-1)}{-2-3}

Simplifying, we get,

m=\frac{-5+1}{-2-3}

Adding the numerator and denominator, we have,

m=\frac{-4}{-5}

Cancelling the negative terms, we get,

m=\frac{4}{5}

Thus, the slope of the line is m=\frac{4}{5}

Therefore, Option C is the correct answer.

Which is the height of the triangle?<br> ( PIC IS PROVIDE PLS HELP ME)
zysi [14]
<h3>Answer: 80 meters</h3>

This is an isosceles triangle. The dashed line is the height which is perpendicular to the base 120. The height is always perpendicular to the base. The dashed line cuts the base into two equal pieces (this only works for isosceles triangles when you cut at the vertex like this).

So we have two smaller triangles each with a base of 60 and a height of x. Focus on one of the right triangles and use the pythagorean theorem to solve for x.

a^2 + b^2 = c^2

x^2 + (60)^2 = (100)^2

x^2 + 3600 = 10000

x^2 = 10000 - 3600

x^2 = 6400

x = sqrt(6400)

x = 80

Each smaller right triangle has side lengths of 60, 80, 100

Note the ratio 60:80:100 reduces to 3:4:5. A 3-4-5 right triangle is a very common pythagorean primitive.

The function f(x) is a quadratic function and a limited table of values is provided below. Write the equation of the quadratic p
OverLord2011 [107]

Answer:

  f(x) = 3x^2 -21x +36

Step-by-step explanation:

The table gives the x- and y-intercepts, which are sufficient to write the equation in factored form. The x-intercepts of 3 and 4 tell you that factors are (x -3)(x -4). When x=0, this product is (-3)(-4) = 12, but the y-intercept value is 3 times that: 36. So, the factored equation is ...

  f(x) = 3(x -3)(x -4)

Multiplying this out, we get ...

  f(x) = 3(x^2 -7x +12)

  f(x) = 3x^2 -21x +36
