Answer:
ai = 190.0
Step-by-step explanation:
I'll presume the sequence is arithmetic, simply because assuming the series is mathematical, there is more than one solution.
Assuming the series is comprised of numbers in an arithmetic progression, you will have... (see attachment for better explanation and step by step.)
Answer:
y=4x−14
Step-by-step explanation:
solve for y.
y+2=4(x−3)
distribute 4
y+2=4x-12
subtract 2 from both sides
y+2+−2=4x−12+−2
y=4x−14
Answer:
y=4x−14
Answer:
These two triangles are congruent.
Step-by-step explanation:
You know this bc the markings on the drawing show that Angle B and Angle D are congruent. Also that AB is parallel to CD. This means that Angle BAC and Angle DCA are congruent by ALTERNATE INTERIOR ANGLES. Also, AC is congruent to itself. That makes the two triangles congruent by ANGLE-SIDE-ANGLE.
Now, you need to know that "congruent" triangles (and shapes in general) are the same size and shape. "Similar" triangles (shapes) are the same shape but not necessarily the same size.
After you divide 3 by 4 and get 75, you multiply that by 40% and you get 0.30.<span />
