Hello :)
Step-by-step explanation:
normal line equation
y = ax + b
the 2 given points give us 2 equations with 2 variables a, b.
we solve that for the general line equation.
-5 = a×-4 + b
-2 = a×-3 + b
subtract equation 2 from equation 1
-3 = a×-1 + 0
-3 = -a
a = 3
-2 = 3×-3 + b = -9 + b
b = 7
so, the line equation is
y = 3x + 7
Answer:
c=-25/4
Step-by-step explanation:
y=c
y=x²+5x
x²+5x=c
x²+5x-c=0
as they intersect at one point only so discriminant=0
b²-4ac=0
5²-4(1)(-c)=0
25+4c=0
4c=-25
c=-25/4
Answer:
Answer: Sum of first 90 terms is Option d. 11655
Step-by-step explanation:
We have to find the sum of first 90 terms of the sequence -4,-1,2,5,8......
First we find the 90th term of the sequence
As we know the formula A(n)= A(1)+(n-1)d
Given from the sequence
A(1) = (-4)
n=90
d = 3
So A(n) = -4+(90-1)3
= (-4)+89×3
= 263
Now we know formula for the sum of any sequence is
Sum S(n) =
Now we know n= 90
A(1) = -4
A(n) =263
Now we put the value in the formula
S(n)=
= 45×259
= 11655
Answer:
Step-by-step explanation:
Factors
- A term in multiplication for an entire variety by which a bigger complete quantity may be divided
- A divisor is an integer that evenly divides a range without leaving the rest
- Factorization is the decomposition of an item right into a product of other objects
- Integer factorization, the manner of breaking down a composite quantity into smaller non-trivial divisors
- A coefficient, a multiplicative thing in an expression, usually more than a few
- The act of forming a component institution or quotient ring in summary algebra
- A von Neumann algebra, with a trivial center
- Factor (graph principle), a spanning subgraph
- Any finite contiguous sub-sequence of a word in a group concept
(b)/(7.8)=-2.15
Multiply each term in the equation by 7.8.
(b)/(7.8)*7.8=-2.15*7.8
Cancel the common factor of (1)/(7.8).
1b=-2.15*7.8
Multiply -2.15 by 7.8 to get -16.77.
1b=-16.77
Divide each term in the equation by 1.
(1b)/(1)=-(16.77)/(1)
Cancel the common factor of 1.
b=-(16.77)/(1)
Divide -16.77 by 1 to get -16.77.
b=-16.77
