Answer:
23
Step-by-step explanation:
Well substitute (if there is no sign and their all stocked together, it’s multiplication)
5(3)2 - 5(3)-8
30-7
23
Answer: Problem 3: 20 laps per day,
Inequality: x >=20 per day
Problem 4: minimum of 8 employees
Step-by-step explanation:
Given that the goal is 600 laps in a month
And a month contains 30days, to achieve 600 laps, we divide 600 laps by 30 days
= 600/30= 20
Reem needs to swim a minimum of 20 laps per day to achieve her goal.
Inequality: x should be greater than or equal to 20 laps daily.
x >= 20
Problem 4:
Given that each employee can paint 85square feet per hour
The building has 1360 square feet and to be completed in two hours
Number of employees to complete the job in one hourwill be 1360/85 = 16
If 16 employees will complete 1360 per hour, then 8 employees will complete the work in 2 hours.
Combine like terms (terms with the same variable (letter)). Remember to bring the sign.
4c - 4d + 8c - 3d
4c + 8c = 12c
-4d - 3d = -7d
12c - 7d is your answer
hope this helps
Answer:
Given : JKLM is a rectangle.
Prove: JL ≅ MK
Since, by the definition of rectangle all angles of rectangles are right angle.
Thus, In rectangle JKLM,
∠ JML and ∠KLM are right angles.
⇒ ∠ JML ≅ ∠KLM
Since, JM ≅ KL (Opposite sides of rectangles are congruent)
ML ≅ ML ( Reflexive )
Thus, By SAS congruence postulate,
Δ JML ≅ Δ KLM
⇒ JL ≅ MK ( because corresponding parts of congruent triangles are congruent)
Hence proved.
- Put
x=0, you would get the y-intercept, so you got one point which would be (0,#)
- Put y=0, you got where the graph would
touch\cross\intersect the x-axis, and the other point is (#,0)
to get x-intercept:
y=0:
3x=2 >>
x=2/3to get y-intercept:
x=0:
<span>-6y=2 >>>
y = -1/3</span>
