A-5B=2x+3-5(x²-5x+1)
- distribute -5 to the parentheses:2x+3-5x²+25x-5
- rewrite:-5x²+2x+25x-5+3
- combine like terms:-5x²+27x-2

❤️Hello!❤️For experimental data it may be good to use linear regression.
For precise data you do not need linear regression.
Step-by-step explanation: If you have a number of experimentally generated data points that are subject to inaccuracies then you can use something like linear regression to generate a linear model that fits the data reasonably well. Many modern calculators have a linear regression capability.
On the other hand, if you are given precise data, you should be able to generate a model that fits the data exactly. For example, given points (
x
1
,
y
1
) and (
x
2
,
y
2
) which are supposed to lie on a line, the equation of the line in point-slope form is:
y
−
y

=
m
(
x
−
x
1) where m
=
y
2
−
y

Answer:
4 623
Step-by-step explanation:
4.623 x 1000
When multiplying by a positive power of 10, move the decimal by the number of zeros
Since we have 3 zeros, move the decimal 3 places to the right
4 623
Answer:
the answer is c 162
Step-by-step explanation:
formula for triangular prism: 1/2*b*h1*h2
substitute the values into the formula:
6*3*18=324
324/2=162
plz vote my answer the brainiest if it helps, thanks!
The angles x and 55.1 degrees are COMPLEMENTARY ANGLES. Please look up that term if necessary.
Subtract the angle 55.1 degrees from ( what? ) to obtain angle x.
