What is the slope of the line through (4, 7) and (5, 12)?
kumpel [21]

Answer: Slope=5

Step-by-step explanation:

To find the slope of the line with 2 given points, you use the formula \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }.

We plug our points into the formula and get:

\frac{12-7}{5-4} =\frac{5}{1} =5.

Our slope is 5.

What is the graph of y = |x - 2|?
Margaret [11]

Answer:

Step-by-step explanation:

Graphing y = (x - h)2 + k

In the graph of y = x2, the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point.

PLEASE I NEED HELP ASAP! Determine if 9x2 - 42x + 49 can be the area of a square. If so, what would the value of x have to be if
Inga [223]
9x^2 - 42x + 49 is a perfect square trinomial. It factors to (3x - 7)^2
If the area is 64m^2 set this equal to the factors and solve.
(3x - 7)^2 = 64
Take the square root of both sides.
3x - 7 = + - 8
3x - 7 = 8 3x - 7 = - 8
Add 7 to both sides.
3x = 15 3x = - 1
Divide both sides by 3.
x = 5 x = -1/3
x cannot be -1/3 because it would make the length negative.
The answer is x= 5

What are the measures of angles M and N?<br> m m m m &lt; M = 119° and m
NNADVOKAT [17]

Answer:

m<M = 113 deg

m<N = 61 deg

Step-by-step explanation:

In an inscribed quadrilateral, opposite angles are supplementary.

m<M + m<K = 180

m<N + m<L = 180

m<M + 67 = 180

m<M = 113

m<N + 119 = 180

m<N = 61
