What is the slope of the line that passes through the points (−10,−8) and (-8, -16) Write your answer in simplest form.
jarptica [38.1K]

Step-by-step explanation:

given,

point = ( -10, -8 ) and ( -8, -16 )

we know,

slope = y2 - y1 / x2 - x1

x1 , y1 = (-10 , -8 )

x2 , y2 = ( -8, -16 )

after inserting the values we got,

→ -16 - (-8 ) / -8 - (-10)

→ -8/2 → -4

therefore, slope of line is -4.

hope this answer helps you dear...take care and may this answer helps you dear!.

Use the quadratic formula to solve x^2-4x+3. Show your work. Then describe the solution
mars1129 [50]
Quadratic formula is x=(-b+-sqrt(b^2-4ac))/(2a)

a= 1, b=-4, and c=3

Therefore, x=(-(-4)+-sqrt((-4)^2-4(1)(3))/(2(1))

Solve for both the plus and minus equations; the answers will be the roots to the quadratic equation.

I'm confused on how to find the length of this triangle.​
sertanlavr [38]

the formula for area=l*w

you know one side is 1.1w (w representing the unknown side) and the area is 3.3w squared. now you need to plug in the numbers you know into your formula which would look like this: 3.3w squared is equal to 1.1w times w. now you need to solve for w by multiplying 1.1w and w to get 1.1w squared. now you are going to divide 1.1 w squared on both sides which gives you w equals 3

Final answer: w=3
