Answer:
Slope: 2
Step-by-step explanation:
Answer:
2. Not enough information
4. Congruent SAS
4. Similar, not enough information to determine congruency.
Step-by-step explanation:
2. We only know one side and one angle are congruent, Not enough to determine congruency
4. We know two sides and the angle between are vertical angles and vertical angles are congruent. SAS is how the triangles are congruent.
6. The three angles are congruent which makes the triangles similar. We need to know a side if they are to be congruent
Solve for x
so assuming that the fractions are
(9/4)-(1/*2x))=4/x then
get all x on one side
add 1/(2x) to both sides
9/4=(4/x)+(1/(2x))
make common denomators with x and 2x
common denomenator is 2x
4/x times 2/2=8/(2x)
9/4=8/(2x)+1/(2x)
add
9/4=9/(2x)
make common denomators with 4 and 2x
common denomator is 4x
9/4 times x/x=9x/(4x)
9/(2x) times 2/2=18/(4x)
9x/(4x)=18/(4x)
multiply both sides by 4x to clear fraction
9x=18
divide both sides by 9
x=2
Answer:
Second table is the table which represents a linear function
Answer:
2.75x + 114 = 320.25
x = $75
Step-by-step explanation:
2.75x + 114 = 320.25
number of hours of labor (2.75) times the cost per hour of labor (x) + cost of parts (114) = total cost (320.25)
2.75x + 114 = 320.25
subtract 114 from both sides
2.75x = 206.25
divide both sides by 2.75
x = 75
------------------------
check the math:
2.75(75) = 114 = 206.25 + 114 = 320.25
