What is the first step in which the student made an error?
o Step 1, because the student should have written a compound statement with "and"
o Step 2, because the student should have graphed the inequalities Y1 SX-4 andy, 51
o Step 3, because the values for x for which yn Sy2 also include values between 3 and 5
Step 4, because the solution is one continuous interval
The first step where the student made an error is in step 4 because the solution is one continuous interval.
What is r continuous interval?A function can be continuous in nature on an interval and this is said to be the time when the function is said to be seen at all point on that given interval and does not get any interruptions or breaks.
Note that in step 3, the values for x for which y₁ ≤ y₂ is x = 3 or x= 5. and in step 4 , the error is here when it state the solution is one continuous interval because there are more than one interval which is (∞, 3) ∪ (5, ∞)

Factor rs - 5s + 5r - 25 by grouping
Answer:
(s+5)(r-5)
Step-by-step explanation:
From the first 2 terms, we can factor s to get
rs - 5s = s(r-5).
Similarly, we can factor 5 form the last 2 terms to get
5r - 25 = 5(r-5).
The original expression then becomes
s(r-5) + 5(r-5).
From here, we can treat (r-5) as a single term and factor the rest to get
(s+5)(r-5),
and we are done.

Answer:
479 ft^2
Step-by-step explanation:
Area of the bottom rectangle = 30 X 20 = 600 sq ft
then subtract the areas of the window and the door
600 - (5x3) - (2x3) = 579 ft^2
Then add the triangular top area
1/2 (20)(10) = 100
579 - 100 = 479 ft^2

The value of PN is 7.5 if the triangles KLJ and NPM are similar triangles.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
The triangles KLJ and NPM are similar triangles.
So the sides of triangle are proportional.
KL/JL = PN/PM
Substitute the values:
5/6 = PN/9
Apply cross multiplication:
45=6PN
Divide both sides by 6:
45/6= PN
7.5=PN
Hence, the value of PN is 7.5.

Answers:
a) x+y = 70b) The graph is shown below. The lines intersect at (20, 50) meaning that she has 20 quarters and 50 dimes.========================================================
Explanation:
a)
x = number of quarters
y = number of dimes
x+y = number of dimes and quarters
x+y = 70 coins total
-----------
b)
Use a graphing tool like Desmos or Geogebra to plot each linear equation on the same xy grid. I'm using Geogebra to get what is shown below.
The red line 25x+10y = 1000 goes through (0,100) and (40,0)
The blue line x+y = 70 goes through (0,70) and (70,0)
The two lines intersect at (x,y) = (20,50)
This means x = 20 and y = 50 pair up together.
Kateri has 20 quarters and 50 dimes
20 quarters = 20*25 = 500 cents = 500/100 = $550 dimes = 50*10 = 500 cents = 500/100 = $5Total value = $5 + $5 = $10
Also note that 20 quarters + 50 dimes = 70 coins total
Both conditions have been confirmed.

Зу – 15 = y +1
I need the answer
y=8
Solution:First, move the y's to the left:3y-y-15=1Now, add 15 to both sides:3y-y=1+15Combine Like Terms:2y=16Divide both sides by 2:y=8Hope it helps.
Do comment if you have any query.
Answer:
y = 8
Step-by-step explanation:
Given equation: Зу - 15 = y + 1
Subtract "y" both sides:
→ Зу - 15 = y + 1→ 3y - y - 15 = y - y + 1→ 2y - 15 = 1Add 15 both sides:
→ 2y - 15 = 1→ 2y - 15 + 15 = 1 + 15→ 2y = 16Divide 2 both sides:
→ 2y/2 = 16/2→ y = 8
