X²-10x+15=0
x²-10x=0-15
x²-10x=-15
x(x-10)=-15
x=-15/(x-10)
I’m not sure about number 9. But number 10 is answer C. This is because there are two sides to a coin, so you are equally likely to land on heads as you are tails. So you take 64 and divide it by 2, and get the answer 32.
Answer:
<h2>
20 degrees</h2>
Step-by-step explanation:
This is a linear pair, whose sum always equals 180 degrees,
hence, we can set up the equation:
2z+140=180
2z=180-140
2z=40
z=40/2
z=20
Thus, the answer is 20 degrees
If one kit contains 235 parts, then all we need to do to find out how many are in 4 of those same kits is multiply the amount in one kit by the amount of kits there are.
235 * 4 = 940
There are 940 parts in 4 of the kits.
Hope that helped! =)
Answer: <em>f(x) </em>= 21 .The output is 21 when the input is 5.
Step-by-step explanation:
f(x) = 4x+1 Substitute the input, 5, for x on the right side <em> f(x) is the equivalent of y, the output you are looking for</em>
<em>f(x) </em>= 4(5) + 1
<em>f(x) </em> = 20 +1
<em>f(x) </em>= 21
