Step-by-step explanation: Substitute the value of the variable into the expression and simplify.
163
Answer:
Step 4 : he should have divided both sides by negative seven
Step-by-step explanation:
Answer:
y=3/4 *x
Step-by-step explanation:
1. the given equation is the equation of line in slope-interception form (y=kx+b), where 3/4 is 'k' and (-4) is 'b'.
2. if the system of the two equations has no solution, it means, the 2d line is parallel to the given one, then 'k' of the 2d line is the same value.
3. common view of the equation of the 2d line is y=3/4 *x+b, where 'b' is number. For example, y=3/4x; y=3/4 *x+1; y=3/4 *x-5/8, etc.
Answer:
b = 15.7 -2a
Step-by-step explanation:
You are asking us to solve for b
2a +b = 15.7
Subtract 2a from each side
2a-2a+b = 15.7 -2a
b = 15.7 -2a
By evaluating the <em>linear</em> function f(x) = x - 3 at x = 5 and discarding the another function in the table given, we conclude that f(5) = 2 belongs to that <em>linear</em> equation.
<h3>What function contains a given relationship?</h3>
In this problem we must check if the given relationship between the <em>independent</em> variable (x) and the <em>dependent</em> variable (y) exists in any of the two functions: (i) a table, (ii) an expression.
After a quick analysis, we conclude that f(5) = 2 is a point of the linear function f(x) = x - 3. Here is the proof:
f(5) = 5 - 3
f(5) = 2
