Correct answer is going to be D
Answer:
6.95 cm
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the height )
Here A = 34.75 and h = 5, thus
34.75 = 5b ( divide both sides by 5 )
b = 6.95 cm
Answer:
y = 1/7x + 22
Step-by-step explanation:
since the line is <u>parallel</u>, the <u>slope should be the same</u>.
so we need to find the y-intercept to put in into slope-intercept form.
what I do, is simply plug in the y and x points into the equation y=mx+b
y=mx+b <em>-formula used</em>
21 = 1/7(-7) + b <em>-plug in</em>
21 = -1 + b <em>-multiply 1/7 and -7</em>
22 = b <em>-simplify to get the y-intercept</em>
since we now know the y-intercept and the slope, we can plug them in to get our answer, which will be y = 1/7x + 22
Answer:
D. (2,1)
Step-by-step explanation:
Fill in the value for y from the first eq (6x-11) into the second:
-2x - 3(6x-11) = -7
Now simplify:
-2x -18x + 33 = -7
-20x = -7-33
20x = 40
x = 2
Now that we have x, plug it into the top eq to get y:
y = 6*2 - 11 = 1
Et voila, x=2 and y=1, so the solution is (2,1).
Answer:
x = 50.5°
Step-by-step explanation:
Use SOH CAH TOA... Since the adjacent and hypotenuse are given, you must use cosine.
cos(x) = 14/22
cos^-1 (14/22) = 50.5°
