Is(1, 6)a solution to the inequality y < 4x + 2?
Answer:
yes, (1,6) is a solution to the inequality y<4x+2.
Step-by-step explanation:
Looking at the equation we can see that the slope is 4 and the y intercept is 2.
Now we will use the slope that is comprised of the rise over the run which is [tex]\frac{rise}{run}[/tex]
The slope is 4 this means that [tex]\frac{rise}{run}[/tex] = [tex]\frac{4}{1}[/tex] and this shows us that the rise is 4 and the run is 1, so starting at (0,2) you go up 4 and over 1 so our next coordinate would be (1,6)
so the answer is yes, (1,6) is a solution to the inequality y<4x+2.
Hope this helps!

Use the provided ruler to measure the segment shown. Find the scale of the drawing. The length of the segment is ___ centimeters. The scale is ___ cm : ___ m.
Answer:
Length of boat = 12,000cm
Scale: 100cm : 1m
Step-by-step explanation:
Find the diagram attached
Given
Length of the boat = 120m
Using the conversion
100cm = 1m
Converting to 120m to centimeters
x cm = 120m
100cm = 1m
Cross multiply
x×1 = 120×100
x = 12,000cm
.
Hence the length of the measured segment is 12,000cm
The scale used will be according to the conversion rate used
The scale used will be 100cm : 1m
Answer:
The actual answer is:
Length if the segment is 4 centimeters.
the scale is 1 cm : 30 m

The Library of Congress in Washington D.C. Is considered the largest library in the world. They often receive boxes of books to be added to their collection. Since books can be quite heavy, they aren't shipped in big boxes. If, on average, each box contains about 8 books, how many books are received by the library in 6 boxes, 10 boxes, or n boxes? Use the space below to tell me how many books are received in: 6 boxes = 10 boxes = n boxes = (Hint: Write an equation!)
Answer: The number of books in 6 boxes = 48
The number of books in 10 boxes = 80
The number of books in n boxes = 8n
Step-by-step explanation:
Given : Each box has contains about 8 books.
Total books : (Number of books in each box) x (Numbers of boxes).
Then, the number of books in 6 boxes = 8 x 6 = 48
Similarly,
The number of books in 10 boxes = 8 x 10 = 80
The number of books in n boxes = 8n
Hence, The number of books in 6 boxes = 48
The number of books in 10 boxes = 80
The number of books in n boxes = 8n

are needed to make 60 cookies?
a) 1.2 cups
b) 0.83 cups
c) 7.5 cups
d) 13 cups
Answer:
My guess would have to be d
Step-by-step explanation:
How many cups of flour are needed to make 60 cookies.
Solution:[tex]60 \times 3 \div 24[/tex]
[tex] \frac{5 \times 3}{2} [/tex]
[tex] = \frac{15}{2} [/tex]
[tex] = 7 \frac{1}{2} or[/tex] [tex]\boxed{\sf{7.5}}[/tex]

Therefore, 7.5 cups of flour are required to make 60 cookies.
Gena and her friends each estimated the quotient of –137.56 divided by –6.12 using compatible numbers. Which shows the best estimate using compatible numbers? Negative 140 divided by negative 7 = 20 Negative 140 divided by 6 = 23.ModifyingAbove 3 with bar Negative 135 divided by negative 7 = 22.5 Negative 135 divided by negative 5 = 27
Answer:
Negative 140 divided by negative 7 = 20
Step-by-step explanation:
Gena and her friends each estimated the quotient of –137.56 divided by –6.12 using compatible numbers.
Using Compatible Numbers: we round up each negative number given to the nearest whole number.
Hence:
-137.56 = -140
-6.12 = -7
Hence:
-140/-7 = -20
Therefore, the best estimate using compatible numbers is Negative 140 divided by negative 7 = 20

what happens when you multiply each side of the inequality by a negitive number
Answer:
What happens when you multiply each side of the inequality by a negative number?
Much like when you divide by a negative number, the sign of the inequality must flip. When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!
Does the inequality sign change when multiplying by a negative?
Because we are multiplying by a negative number, the inequalities change direction.
What is the rule for negatives and inequalities?
If a < b and if c is a negative number, then a · c > b · c. Multiplying each side of an inequality by a negative number reverses the direction of the inequality symbol. Dividing each side of an inequality by a negative number reverses the direction of the inequality symbol.
Examples of inequality by a negative number
3x < 7+3
Multiply (or divide) both sides by a negative number. Swapping left and right-hand sides.

ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. In kilometers, how far did Jada run in 60 minutes ?
PLZZZZZ HELP ASAP
Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.
Write the equation of the line that passes through the given points. (2,9.5) and (0,0.5)
Answer:
[tex]y = \frac{9}{2}(x) + \frac{1}{2}[/tex]
Step-by-step explanation:
Linear equations can be written as
[tex]y = mx + b[/tex]
m is [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
b is the y intercept
[tex]\frac{9.5 - 0.5}{2-0}\\ =\frac{9}{2} \\y = \frac{9}{2}x+b\\\frac{1}{2}= \frac{9}{2}(0) + b\\ b = 1/2[/tex]
plug in to verify
[tex]9.5 = 9/2(x) + 1/2\\\\9.5 = 9/2(2) + 1/2\\9.5 = 9 + 1/2\\9.5 = 9.5[/tex]

Yousef is cutting pieces of construction paper so he can make cards for his family. Each piece of paper is 1112 inches wide. If he cuts that width so he would have two equal-sized smaller pieces, how wide will each smaller piece be?
Answer:
556 inches
Step-by-step explanation:
Given that:
The width of the construction paper is 1112 inches wide ;
Cutting the width to obtain two equal sized smaller pieces ;
(Width size of the original construction paper ÷ Number of smaller pieces)
= (1112 inches ÷ 2)
= 556 inches.
Hence, the smaller pieces will be 556 inches wide.
