Find the slope of the line passing through the points (-5, 3) and (7,9).

dybincka [34]

Answer:

$\huge\boxed{slope=\dfrac{1}{2}=0.5}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points

$(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9$

Substitute:

$m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}$

Which of the following is true given the inequality below?

ra1l [238]

Answer:

D. is to the right of -0.9 on the horizontal number line

Step-by-step explanation:

The given inequality is $- \frac{4}{5} > - 0.9$ i.e. - 0.8 > - 0.9 .......... (1)

Now, when in a number line a number a is greater than another number b, then a must be placed to the right of the number b on the number line.

So, in our case - 0.8 > - 0.9 is true and - 0.8 is tot he right of - 0.9 on the horizontal number line. (Answer)

Quadrilateral ABCD is a parallelogram. DE = 6.1 cm and m∠DAB = 120°. What is BC? cm What is m∠BCD? ° What is AB? cm What is EB?

Ainat [17]

We know that

There are six important properties of parallelograms to know:

1) Opposite sides are congruent (AB = DC and AD=BC).
2) Opposite angles are congruent (D = B and A=C)
3) Consecutive angles are supplementary (A + D = 180° and D+C= 180°).
4) If one angle is right, then all angles are right.
5) The diagonals of a parallelogram bisect each other.
6) Each diagonal of a parallelogram separates it into two congruent triangles.

Part 1) What is BC?
BC=AD-----------> BC=10 cm--------> by Opposite sides are congruent

the answer Part 1) is
BC=10 cm

Part 2) What is m∠BCD?
m∠BCD=m∠DAB-----> m∠BCD=120°----> by Opposite angles are congruent

the answer part 2) is
m∠BCD=120°

part 3) What is AB?
AB=CD------> AB=5 cm----> by Opposite sides are congruent

the answer Part 3) is
AB=5 cm

Part 4) What is EB?
EB=DE-----> EB=6.1 cm----> by The diagonals of a parallelogram bisect each other.

the answer Part 4) is
EB=6.1 cm
