Find the slope and reduce. P = (- 3, 3) Q = (1, 3)

Mathematics
1 answer:
Kryger [21]3 years ago
8 0

Answer: slope = 0

Step-by-step explanation:

The formula for finding slope is given as :

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

x_{1} = -3

x_{2}= 1

y_{1}=3

y_{2}=3

substituting into the formula , we have :

m = \frac{3-3}{1-(-3)}

m = \frac{0}{4}

m = 0

Therefore : slope = 0

Factor completely 3x(x + 2) + 4(x + 2). (1 point) (x + 2)(7x)
Nezavi [6.7K]

ANSWER

(x + 2)(3x + 4)

EXPLANATION

The given expression is

3x(x + 2) + 4(x + 2)

We can see that (x+2) is the greatest common factor.

We factor to obtain;

(x + 2)( 3x + 4)

The correct choice is C.

CD is perpendicular to AB and passes through point C5, 12).
Aleksandr-060686 [28]

Answer:

x intercept of CD = 17

Step-by-step explanation:

We are given a line AB with its end coordinates. and Another line segment CD which is perpendicular to AB. We have the coordinates of C , and we are asked to find the x intercept of line CD.

For that we need to find the equation of CD

we have coordinates of C , and hence if we have slope of CD we can find equation of CD

Slope of CD can be determine with the help of slope of AB as CD⊥ AB

So, the slope of CD mCD = -\frac{1}{mAB}

Hence we start from determining slope of AB

slope is given as

m= \frac{y_2-y_1}{x_2-x_1}

m= \frac{14-(-3)}{7-(-10)}=\frac{17}{17}=1

Hence mAB=1

There fore mCD=-1

(∵  Product of Slopes of two perpendicular lines is always -1)

Now we find the equation of CD with the help of slope -1 and coordinates of C(5,12)

m=\frac{y-y_1}{x-x_1}

-1=\frac{y-12}{x-5}

-x+5=y-12

y=-x+17

Hence we have our equation , now in order to find the x intercept we keep y = 0 in it and solve for x

0=-x+17

x=17

Hence the x intercept is 17
