Answer:
If the lines are parallel, final form of his solution is
b) -5 = -5+1
Step-by-step explanation:
As the options are not given in the question and the question is incomplete, lets complete the question first.
Giovani solves a system of linear equations algebrically, he concludes that the lines are parallel. Which could be his final answer.
a) -5 = -5
b) -5 = -5+1
c) 11 = 11
d) 5 = 5
We know that parallel lines never cross at any point, there is no intersection point, which eventually means that there is no solution to the given equations. A system of equations which have no solution is called an inconsistent system of equations, and it graphs the parallel line.
From the options we can clearly see that only (b) has no solution, while all the rest of the options have solutions. Hence, -5 = -5+1 represents parallel lines.
Answer:
92°F
Step-by-step explanation:
in degrees Fahrenheit,
t=7
f(7)=64 + 4(7)
=92
Answer:
A.) f(x) = 45 - 4(x - 1)
Step-by-step explanation:
The measure of angle A is 144.3 degrees and the angle to cut the molding is 54.3 degrees
<h3>How to solve for angle A?</h3>
Start by solving the acute part of angle A using the following sine function
sin(Ax) = (30 - 4)/32
Evaluate the quotient
sin(Ax) = 0.8125
Take the arc sin of both sides
Ax = 54.3
The measure of angle A is then calculated as:
A = 90 + Ax
This gives
A = 90 + 54.3
Evaluate
A = 144.3
Hence, the measure of angle A is 144.3 degrees
<h3>The angle to cut the molding</h3>
In (a), we have:
Ax = 54.3
This represents the angle where the molding would be cut
Hence, the angle to cut the molding is 54.3 degrees
