The answer is 0.91 because you divide 5 into 4.55
Answer:
c) 4. i think.
Step-by-step explanation:
Answer:
Intercept form
The standard form of the equation of the line
4 x + 5 y +20 =0
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that x-intercept (a) = -5
and y-intercept (b) = -4
Intercept form
⇒
4 x + 5 y = -20
<u><em>Final answer:-</em></u>
The standard form of the equation of the line
4 x + 5 y +20 =0
Answer:
Subsitution
Step-by-step explanation:
We have the equations:
x=2y-1
3x+y=11
The 3 methods of solving systems of equations are:
graphing
substitution
addition/elimination
Graphing involves graphing the two equations and finding their point of intersection, which is the answer
Substitution involves isolating one of the variables in one of the equations, then substituting the resulting expression into the other equation to find both numbers
Addition/Elimination involves adding the two equations together to clear a variable, solving for the other variable, and substituting the answer to the first variable in one of the equations to find the value of the cleared variable from before
Since we have x already isolated onto one side in the first expression, we can easily substitute it as 2y-1 in the second equation.
Therefore, substitution is the best method to solve this graph.
hope this helps!
Answer:
I believe C, or the answer you have chosen, is correct.
Step-by-step explanation:
In this question, we add like, AKA similar, terms.
There is nothing to match x^2, so we leave it alone and put it at the head of equation since it has the highest power:
x^2
There is nothing to match -x, so we also leave it alone and put it next to x^2, keeping its sign:
x^2 - x
We can add 1 and 5 to get 6, so we put 6 next to the -x to get our final equation:
x^2 - x + 6.
See how easy that was? :) Hope this helps you and you get a good grade on your test!!
