Does the point (4, 10) satisfy the inequality y greater than or equal to 2x + 2?
Answer:
Yes, the point (4,10) satisfies the inequality.
Step-by-step explanation:
In order to answer this question, we can plug the values x = 4 and y = 10 into the inequality:
y ≥ 2x + 2
10 ≥ 2(4) + 2
Then solve:
10 ≥ 8 + 2
10 ≥ 10
Since the value 10 is greater than or equal to itself, the inequality is true at the point (4,10).
Step by step solve 18×20, I find double 18 and then multiply by 10

Answer:
(d) The y-intercept of the graph of the relationship is ( 0, 1).
Step-by-step explanation:
The y-intercept of a proportional relation is always zero. If it is 1, the relationship must be non-proportional.
What is the slope of the line ?
Answer:
[tex]m=\frac{4}{5}[/tex]
Step-by-step explanation:
You can calculate the slope with just 2 points, so find 2 points on the line that land perfectly on the grid.
I'll use (-2, 0) and (3, 4) here
To calculate slope:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
where (x1, y1) is your first point and (x2, y2) is your second. Technically they can go in any order, but I think its generally easier to consider first-to-last as left-to-right.
Plug in those 2 points and solve:
[tex]m=\frac{4-0}{3--2}\\m=\frac{4}{5}[/tex]
Think of slope as rise over run. A slope of [tex]\frac{4}{5}[/tex] means it rises 4, and goes over 5. It's also literally rise over run, as the top number (rise) is over the bottom number (run).

A city planner wants to build a road perpendicular to D Street. What should be the slope of the new road?
Answer:
0
Step-by-step explanation:
The slope of D street on this graph is "undefined." A perpendicular will have a slope that is zero. That is, D is a vertical line on the map, so the perpendicular will be a horizontal line.
The slope of the new road should be zero.

Could someone help me figure this out?
Answer:
The area of a rectangle is the length multiplied by its breadth.
Since the length is [tex]3(n-1)[/tex] and the breadth is [tex]n+2[/tex] and the area is 54, you can form an equation as followed:
[tex]3(n-1)*n+2=54[/tex]
[tex]3n(n-1)+2=54[/tex]
Expand:
[tex](3n*n)-(3n*1)+2=54[/tex]
[tex]3n^2-3n+2=54[/tex]
Subtract both sides by 54:
[tex]3n^2-3n+2-54=54-54[/tex]
[tex]3n^2-3n-52=0[/tex]

A squirrel burrowed 10 holes in 8 minutes. How many holes could the squirrel burrow in 12 minutes?
Answer:
15
Step-by-step explanation:
Fast and loose: To go from 8 to 12 minutes you're adding half the time (4 minutes). So it has time to burrow only half the holes in the extra time, so 5. Total, 10+5=15.
Crunching numbers: it's a simple proportion:[tex]10:8 = x :12[/tex] from which, cross-multiplying you get [tex]8x=12\times10 \rightarrow 8x=120 \rightarrow x=15[/tex]
Find the value of x.
8.
x+9
2x
[tex]2x = \frac{x+2}{2} => 4x = x + 2 => 3x = 2 => x = 2/3[/tex]

Step-by-step explanation:
Mrs. Ashton buys journals for the students in her language arts class. She pays $64.48 for all of the journals. If there are 26 students in her class, how much does each journal cost?
Answer:
Each journal costs $2.48
Step-by-step explanation:
Let X be the cost of a single journal.
You can write this equation to represent the problem:
26x = 64.48
(26 times the cost of the journal is $64.48)
Then just solve for x by dividing both sides by 26:
[tex]26x=64.48\\\frac{26x}{26} =\frac{64.48}{26}\\x=2.48[/tex]
Each journal costs $2.48

divide £64 in the ratio5 3:
Answer:
£40 : £24
Step-by-step explanation:
sum the parts of the ratio, 5 + 3 = 8 parts
Divide the amount by 8 to find the value of one part of the ratio
£64 ÷ 8 = £8 , then
5 parts = 5 × £8 = £40
3 parts = 3 × £8 = £24
£64 in the ratio 5 : 3 is £40 : £24
Answer:
24:40
Step-by-step explanation:
Let the ratio be 3x and 5x
3x+5x=64
8x=64
X=8
ratio=3(8):5(8)

now,
3×180 = 540°
therefore, option C 540° is correct
hope this answer helps you dear! take care
Answer:
540
Step-by-step explanation:
Each triangle only has 180 degrees
We have 3 triangle, 180 + 180 + 180 = 540 degrees
a kayak rental shop rents 28 kayaks per week when it charges $25 per day. For each $5 increase in price, the shop loses four kayak rentals per week. How much should the kayak rental shop charge to maximize weekly revenue? What is the maximum weekly revenue?
If a kayak rental shop rents 28 kayaks per week when it charges $25 per day. For each $5 increase in price, the shop loses four kayak rentals per week. 720 is the maximum weekly revenue
What is Equation?Two or more expressions with an Equal sign is called as Equation.
It is given that a kayak rental shop rents 28 kayaks per week when it charges $25 per day
For each $5 increase in price, the shop loses four kayak rentals per week. we need to find How much should the kayak rental shop charge to maximize weekly revenue
R(x)=(25+5x)(28-4x)
=5(5+x)4(7-x)
=20(5+x)(7-x)
=-20(5+x)(x-7)
when x=1 it is maximum
Price when x =1 is 25+5(1)=30
To calculate maximize revenue
R(1)=(25+5)(28-4)
=30(24)
=720
Hence the maximum weekly revenue is $720.

• She earns 12.5 points for each visit to the movie theater.
• She needs at least 125 points for a free movie ticket.
Write and solve an inequality which can be used to determine v, the number of visits
Aaliyah can make to earn her first free movie ticket.
Answer:
30 +12.5v ≥ 125v ≥ 7.6Step-by-step explanation:
Aaliyah wants her accumulated points to be at least 125. Her accumulated points will be ...
(reward points) + (visit points)×(number of visits)
30 +12.5v ≥ 125 . . . . . the inequality
