Answer:
4
Step-by-step explanation:
To find the slope you must use the slope formula.
it is y2-y1/x2-x1. with the points (-26,-37) and (-32,-61)
you do -61 minus -37 divided by -32 minus -26. first do -61 minus -37 = -24. then do -32 minus -26 = -6. And -24 divided by -6 = 4. the slope is 4.
Hope this helps. Sorry if its confusing.
Answer:
cm.
Step-by-step explanation:
A diagonal of a square + two of its sides creates a <em>45-45-90 triangle</em>. The relation between the lengths of said triangle is <em>1:1:√2</em>. In this case the diagonal is the √2 of the ratio.
That means that the side length should be <em>18/√2</em>, as this times √2 makes 18.
18/√2 simplifies to (18√2)/2 = (9√2)/2.
Answer:
x = 12
Step-by-step explanation:
Looking at the diagram, we can deduct that the appropriate formula to use is form power of a point, specifically when two secants intersect outside of a circle. Using this, you get the equation:
(x + 5 + 7)(7) = (x + 1 + 8)(8)
And, you can simplify and solve:
(x + 12)(7) = (x + 9)(8)
7x + 84 = 8x + 72
84 = x + 72
x = 12
-4.5 - 4.2(-x - 5.5) = 3x
-4.5 + 4.2x + 23.1 = 3x
18.6 + 4.2x = 3x
subtract 4.2x from both sides of the equation
18.6 = -1.2x
divide -1.2 from both sides of the equation
-15.5 = x
