1.5x + 4.5y = 18. Where does the graph intersect the y-axis?
Answer:
4
Step-by-step explanation:
Substitute x for 0 and solve.
1.5(0)+4.5y=18
4.5y=18
y=4
For the equation, 1.5x + 4.5y = 18 at x = 0 the graph will intersect at 4 of y -the axis.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the equation is 1.5x + 4.5y = 18. For the value of y substitute x for 0 and solve.
1.5x + 4.5y = 18
1.5(0)+4.5y=18
4.5y=18
y=4
The value of y is equal to 4 means that the graph will intersect the y-axis at 4.

:)Hope you enjoy this:)Hana rents a car for a day. Her car rental company charges $50 per day and $0.40 per mile. Peter rents a car from a different company that charges $70 per day and $0.30 per mile. How many miles do they have to drive before Hana and Peter pay the same price for the rental for the same number of miles?
50 + .4x = 70 + .3x
.4x = .3x + 20
.1x = 20
x = 200
Let x be the number of miles.
They have to drive 200 miles.
They will drive 200 miles before paying same amount.
Let the number of miles that they will drive together and pay the same amount be represented by x.
Since Hana's car rental company charges $50 per day and then $0.40 per mile, this can be represented as:
= 50 + (0.40 × x)
= 50 + 0.40x
Since Peter rents a car from a different company that charges $70 per day and then $0.30 per mile, this will be:
= 70 + (0.30 × x)
= 70 + 0.30x
Then we will equate both Hana's and Peter's equation together and this will be:
50 + 0.40x = 70 + 0.30x
Collect like terms
0.40x - 0.30x = 70 - 50
0.1x = 20
x = 20/0.1
x = 200
In conclusion, they will drive 200 miles before paying thesame amount

Aldo the trainer has two solo workout plans that he offers his clients: plan a and plan b. Each client does either one or the other (not both). On friday there 8 were clients who did plan a and 3 who did plan b. On saturday there were 3 clients who did plan a and 5 who did plan b. Aldo trained his friday clients for a total of 7 hours and his saturday clients for a total of 6 hours. How long does each of the workout plans last?
Answer:
x = number of hours to train plan a clients
x = 0.55 hour
y = number of hours to train plan b clients
y = 0.87 hours
Step-by-step explanation:
Friday
Plan a = 8 clients
Plan b = 3 clients
Total hours = 7
Saturday
Plan a = 3 clients
Plan b = 5 clients
Total hours = 6
Let
x = number of hours to train plan a clients
y = number of hours to train plan b clients
8x + 3y = 7 (1)
3x + 5y = 6 (2)
Multiply (1) by 5 and (2) by (3)
40x + 15y = 35 (3)
9x + 15y = 18 (4)
Subtract (4) from (3)
40x - 9x = 35 - 18
31x = 17
Divide both sides by 31
x = 17 / 31
= 0.548 hour
Approximately
x = 0.55 hour
Substitute x = 0.55 hour into (1)
8x + 3y = 7
8(.55) + 3y = 7
4.4 + 3y = 7
3y = 7 - 4.4
3y = 2.6
Divide both sides by 3
y = 2.6 / 3
= 0.867 hours
Approximately
y = 0.87 hours
x = number of hours to train plan a clients
x = 0.55 hour
y = number of hours to train plan b clients
y = 0.87 hours
The classrooms in the Oakhurst School District are painted every summer. Seven gallons of paint are needed to paint 3 classrooms. How many more gallons are need to paint the 129 classrooms at North High School than the 48 classrooms at Edgewater Elementary?
Answer:
189 gallons
Step-by-step explanation:
7 gallons for 3 classrooms, so 7/3 for 1 classroom
multiply 7/3 * 129 to get 301 gallons at North High School
multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary
301 - 112 = 189 gallons more at North High School than at Edgewater Elementary
The more gallons should be 189 gallons
The calculation is as follows:
7 gallons for 3 classrooms, so 7 by 3 for 1 classroom
Now
we have to multiply 7 by 3 with 129 so that 301 gallons at North High School could come
Now
multiply 7 by 3 with 48 to get 112 gallons at Edgewater Elementary
Now
= 301 - 112
= 189 gallons more

the position of a deep sea probe is -2 3/4 fathoms relative to the sea level. after finishing taking data, it moves to -2 5/8 fathoms relative to sea level. which was deeper, the first mission, or the second. (i’m in modern high school which means i get collage questions, i only have 1 hour left to get this done, someone help!)
Answer:
The first missionStep-by-step explanation:
The depth readings are
The first mission: - 2 3/4 fathomsThe second mission: - 2 5/8 fathomsComparing the readings
- 2 3/4 = - 2 6/8 and - 2 5/8Absolute values compared
2 6/8 > 2 5/8Indicating the greater value on the first mission
As per above, the first mission was deeper

As OP bisects ∠AOR, ∠AOP = ∠POR = 55°
So, ∠AOR = ∠AOP + ∠POR = 55° + 55° = 110°
As OS bisects ∠ROB, ∠ROS = ∠SOB = x
As total angle on a line is 180°,
110° + x + x = 180°
=> 2x = 70
=> x = 35°
∠POS = ∠POR + ∠ROS = 55° + x = 55° + 35°
=> ∠POS = 90°
