Answer:

x=5   x=3

Step-by-step explanation:

x^2 - 8x + 15 = 0

Factor

What 2 numbers multiply to 15 and add to -8

-5*-3 = 15

-5-3 = -8

(x-5)(x-3) =0

Using the zero product property

x-5 =0    x-3 =0

x=5   x=3

What is the slope of this graph
Masja [62]

Answer:

Slope, m = 5

Step-by-step explanation:

Picking points on the x-axis and y-axis of the graph;

Point on x-axis (x1, x2) = 2, 4

Points on the y-axis (y1, y2) = 10, 20

To find the slope;

Mathematically, slope is given by the formula;

Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis}

Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}}

Substituting into the equation, we have;

Slope, m = \frac {20 - 10}{4 - 2}

Slope, m = \frac {10}{2}

Slope, m = 5

Rhonda graphs a point B in Quadrant I on the coordinate plane, so that point B is 1 1/2 units away from point A.
Bas_tet [7]

Answer:

It would be (1/2, 1/2)

Step-by-step explanation:

Since we know that quadrant 1 is (+.+) that eliminates the bottom two answers since there is a negative. Then what we do is we see that the first answer (1, 1/2) is more than 1 1/2 units away. Hope this helps!
