Since it is negative you go behind the .

so you would go 5 spaces behind the point

Solve x2 − 10x = −13.

aev [14]

Answer:

B

Step-by-step explanation:

First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial $x^{2}-10x+13$ . We can now use the quadratic formula to solve.

Remember that the quadratic formula is

$\frac{-b+/-\sqrt{b^{2}-4ac } }{2a}$

Substitute the numbers from the equation into the formula.

$\frac{-(-10)+/-\sqrt{(-10)^{2}-4(1)(13) } }{2(1)}$

Simplify:

$\frac{10+/-\sqrt{100-52} }{2}$

$\frac{10+/-\sqrt{48} }{2}$

Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with $5+/-\sqrt{48}$ .

Hope this helps!

(50 POINTS) A group of workers is harvesting berries at a constant rate. An equation that represents the number of baskets of be

goldenfox [79]

Hi There!

Follow y = mx + b

m = slope

b = y intercept

(a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time?

Slope = 5

Y intercept = 10

(b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.

The rate of change is how much it takes for the amoun to change. The initial amount should be going up with a slope of 5 each time.

(c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.

Start at the origin than continue with a slope of 5 and make sure the y intercept is correctly graphed.

Which undefined term is needed to define an angle?<br><br> Plane<br> Point<br> Ray<br> Line

Aleks04 [339]

Point.

<h3>Further explanation</h3>

The angle is determined by three points, we call it A, B, C, with A ≠ C and B ≠ C.
We express an angle with three points and a symbol ∠. The middle point represents constantly vertex. We can, besides, give angle names only with vertices. For example, based on the accompanying image, the angle can be symbolized as ∠BAC, or ∠CAB, or ∠A.

This is one of the classic problems of Euclidean geometry.

Undefined terms are the basic figure that is undefined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane. These key terms cannot be mathematically defined using other known words.

A point represents a location and has no dimension (size). It is marked with a capital letter and a dot.
A line represents an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
A plane represents a planar surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.
