Answer: x is 20
Step-by-step explanation:
This is ratio
a : c = b : x and d : unknown
a : c = 9 : 12 = 3 : 4 which is 9/12
b : x = 15 : x which is 15 / x
So the proportion will be :
3/4 = 15/x
So Cross multiplying
3x = 90
Divide both side by 3
x = 90/3
x = 20
Hello DestinyKiara99 o/
We can solve this equation using the quadratic formula
Check it out...
x² + 6x - 24 = 0
Δ = 6² - 4.1.(-24)
Δ = 36 + 96
Δ = 132
x = -6 +/- √132 x' = -3 + √33
<span> -------------- /
2 \
x'' = - 3 - </span>√33
The correct answer is the letter D
I hope this help =)
Answer:
<h2>The answer is 1</h2>
Step-by-step explanation:
The slope of the line between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question is points are
(8, 1) and (-1, 10)
Substitute the values into the above formula and solve for the slope
That's

We have the final answer as
<h3>1 </h3>
Hope this helps you
