Find the gradient of the line segment between the points (-8,6) and (-10,14)

Answers

Answer 1
Answer:

The required gradient of the line between the points (-8,6) and (-10,14) is -4.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The gradient of the line segment between points (-8,6) and (-10,14) is given as,

The gradient of the line = slope of the line,
m = (y₂ - y₁) /  (x₂ - x₁)

Substitute the value in the above equation,
m = 14- 6 / -10 + 8
m = 8 / -2
m = -4

Thus, the required gradient of the line between the points (-8,6) and (-10,14) is -4.

Answers

4y-11=21
Add 11 to 21.
4y=32
Divide both sides by 4.
y=8
My steps may be really weird, but please don't ridicule me. 

1. 11+21

. Tina walked 20 miles for a fundraiser. Liawalked m miles. Tina walked 4 times as
far as Lia. Which equation can be used to
find m, the number of miles Lia walked?

Am= 4 x 20
B20 = 4 x m
C20 = m = 4
Dm = 20 + 4

Answers

Answer:

The relation for the distance cover by Tina and Lia is 20 = 4 × m

Option B

Step-by-step explanation

Given as :

The distance cover by Tina = D_1 = 20 miles

The distance cover by Lia = D_2 = m miles

According to question

Tina walked 4 times as far as Lia

So, The distance cover by Tina = 4 × The distance cover by Lia

Or, D_1 = 4 ×  D_2

I.e 20 miles = 4 × m miles

or. 20 = 4 × m

So, relation is 20 = 4 × m

Hence, The relation for the distance cover by Tina and Lia is 20 = 4 × m

If c(x) = 4x – 2 and d(x) = x^2+ 5x, what is (c circle d) (x)?

Answers

Answer:

4x² + 20x - 2

Step-by-step explanation:

To evaluate (c ￮ d)(x), substitute x = d(x) into c(x)

c(x² + 5x)

= 4(x² + 5x) - 2

= 4x² + 20x - 2

Which values of p and q would make the value of the following expression equal to 58i? (3 – 7i)(p + qi)i

Answers

we are given

(3-7i)(p+qi)i=58i

firstly, we will simplify left side

and then we can compare it with right side

so, we can distribute

(3p+3qi-7pi-7qi^2)i=58i

(3p+3qi-7pi+7q)i=58i

we have i on both sides

so,i will get cancelled

(3p+3qi-7pi+7q)=58

(3p+7q+(3q-7p)i)=58

we can also write as

(3p+7q)+(3q-7p)i=58+0*i

now, we can compare

and we get

3p+7q=58

3q-7p=0

now, we can solve for p and q

we get

q=7,\:p=3.............Answer

Answer:

For short the answer is A.      p = 3 , q = 7
