Answer:

Put both equations into standard form (Ax+By=C).

Multiply one or both of the equations by a number so that you will have opposite coefficients on the same variable.

Add the two equations together. Add the x's, the y's, and the numbers.

Solve for the variable.

Take your answer from the last step and plug it into of the equations (pick the one that looks easiest).

Your solution will be in the form of a coordinate point (x,y).

Answer: 4 inches

Step-by-step explanation: 1,944 / 18/ 9 / 1/3 = 4

Based on the calculations, the height of this pyramid is equal to: D. 36 inches.

Given the following data:

Mathematically, the volume of a pyramid is calculated by using this formula:

Volume = 1/3 × b × h

Where:

For the base area, we have:

Base area = length × breadth

Base area = 18 × 9

Base area = 162 square inches.

Substituting the given parameters into the formula, we have;

1,944 = 1/3 × 162 × h

1,944 = 54h

h = 1,944/54

Height, h = 36 inches.

Answer:

  (c)  -2/5

Step-by-step explanation:

A "zero" or "root" or "x-intercept" of a function is a value of the independent variable (x) that makes the function (f(x)) have a value of zero. It is found where the graph of the function crosses the x-axis.

A quadratic function will have two (2) zeros. If they are different, one will be smaller than the other (leftmost on the number line).

You may recognize that 25x² and 4 are both perfect squares, (5x)² and 2², respectively. That means the expression (25x² -4) is the difference of squares.

The difference of squares is a special polynomial form, useful for the way it factors:

  a² -b² = (a -b)(a +b)

Here, that means the factored form of f(x) is ...

  f(x) = (5x -2)(5x +2)

The "zero product rule" says a product can only be zero if one or more factors is zero. This is exceptionally useful for determining the zeros of a polynomial function from its factored form.

It tells us f(x) = 0 only when one of (5x-2) = 0, or (5x+2) = 0. These are simple equations to solve to find the corresponding values of x:

  5x -2 = 0   ⇒   5x = 2   ⇒   x = 2/5

  5x +2 = 0   ⇒   5x = -2   ⇒   x = -2/5

The above tells us the zeros of f(x) are -2/5 and 2/5. These values of x make f(x) = 0. The smaller zero is the one that is more negative: -2/5.

  smaller zero: -2/5

Additional comment

A polynomial may have complex zeros. Only the real zeros will be x-intercepts on a graph of the function. Complex zeros must be found another way, not by graphing.

Answer:

5. Area = 28.5 cm; 6. Area = 544,500 cm

Step-by-step explanation:

Area = Length×Width

5. You have to convert the mm to cm by dividing the mm by 10. Then just multiply the length and width.

6. Same thing; different unit, convert the m to cm (or vice versa, not sure which unit you need to answer in) and multiply the length and width.

Answer: She will be walking south or 90 degrees

Step-by-step explanation:

She walks ten spaces forward from where she started meaning the east

She turns 45 degrees left which places her at northeast

The walking doesn't affect her direction

So look at it like -45+25+110

This equals 90 degrees or south.

Answer:

B) x²+2x-35=0; the factors are (x+7)(x-5)

Step-by-step explanation:

The quadratic equation which has the solutions as x = -7 and 5 may be x² + 2x - 35 = 0, the factors are (x + 7) and (x - 5) and (x + 7)(x - 5) = x² + 2x - 35.

Quadratic equations are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

Given that,

a quadratic equation has the solutions x = -7 and 5.

There are two options, x² + 2x - 35 and x² - 2x - 35

Using the factorization method, a quadratic equation ax² + b x + c = 0 can be factored as (x + p)(x + q) where pq = c/a and p + q = b/a.

Consider, x² + 2x - 35 = 0

There are numbers 7 and -5 that 7 - 5 = 2 and 7 × -5 = -35

So it can factored as,

(x + 7) (x - 5) = 0

Solutions are x = -7 and x = 5

Hence the quadratic equation is x² + 2x - 35 = 0.
