Answer:
Step-by-step explanation:
In this problem, we have the following linear equations:
y=3x+5
y=ax+b
We know that a linear equation is an equation for a line. In a system of linear equations, two or more equations work together.
1. What values for a and b make the system inconsistent?
A system is inconsistent if and only if the lines are parallel in which case the system has no solution. This is illustrated in the first Figure bellow. Two lines are parallel if they share the same slope. So, the system is inconsistent for:
a=3
for any value of b
2. What values for a and b make the system consistent and dependent?
A system is consistent if and only if the lines are the same in which case the system has infinitely many solutions. This is illustrated in the second Figure bellow. So, the system is consistent and dependent for:
a=3 and b=5
Here a photo of the answer. The first thing you have to do is split the figure into separate shapes. Find the area of the shapes, then add them all together.
Answer:
9/2
Step-by-step explanation:
perpendicular lines have slopes that are opposite and reciprocal
the reciprocal of -2/9 is 9/2
Answer:
109
Step-by-step explanation:
line AB is 180 degrees because a circle is 360 degrees and half a circle is 180 degrees.
Add 42 degrees and 29 degrees. 42+29 = 71
Then subtract. 180 - 71 = 109
So therefore 
Hope this helps:)
Answer:
yep
Step-by-step explanation:
when you divide a fraction u can use the KCF method which is basically:
(keep) the first fraction the same
(change) the division sign in the middle to a multiplication sign
(flip) the second fraction
basically because you have to flip the 1/4 when you divide it, it'll be the same as a 4/1 anyways
