Answer:
the slope is -3/2 and intercept is 0,3
Answer:
g(-5) = -127
Step-by-step explanation:
Plug in -5 for x:
g(-5) = (-5)^3 - 2
= -125 - 2
= -127
Answer:
2by8 of marians garden
Step-by-step explanation:
6.3 r < -45.36
Here first we have to solve for r and for that we need to get rid of 6.3 .
To get rid of 6.3, we divide both sides by 6.3 that is
r < -7.2
So the solution is all the values which are less then -7.2
And for graph, we put a blank circle or a parenthesis that is () on -7.2 and extend a line to the left side since the inequality is less then .
By substitution, the solution of the system of equations, 4x + 2y = 7 and y = 5x, is (1/2 , 5/2).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
4x + 2y = 7 (equation 1)
y = 5x (equation 2)
Since the second equation is already expressed in y in terms of x, substitute the second equation to the first equation.
4x + 2y = 7 (equation 1)
4x + 2(5x) = 7
4x + 10x = 7
Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.
4x + 10x = 7
14x = 7
x = 1/2
Substitute the value of x in the second equation and solve for y.
y = 5x
y = 5(1/2)
y = 5/2
Hence, the solution of the given system of equations is (1/2 , 5/2).
