Mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling.
Answer:
I think its 90°, since it l00ks like a right angle
Answer:
Yes
Step-by-step explanation:
The answer using distributive property is the same as using original way to caculate it.
3+5(2+4) = 3+5(6) =3+20 =33
Step-by-step explanation:
(9a4 + 2a2 + 5) – (16a4 – 7a2 + 1)
A. 25a4 – 5a2 – 4
B. –7a4 – 5a2 + 6
C. 25a8 + 9a4 + 6
D. –7a4 + 9a2 + 4
5.Multiply 9x2(2x2 + 8x).
A. 18x4 + 72x3
B. 18x2 + 72x3
C. 11x4 – 17x3
D. 90x4
Find the slope first: 4=x 2=y 1=x2 -7=y2
-7-2/1-4=-9/-3
So the slope is -9/-3
so far we have y=-9/-3x-b
then we replace
2=-9/-3(4)-b
2=-9/-3*4-b
2=12-b
12-2=10
10=b
So y=3x-10
