Lily drives 90 miles in 2 hours. If she drives at the same rate, how far does lily travel in each of the following time intervals: 1 hour, 1/2 hour, and 3 hours? Please solve in at least two different ways. You could make a bar model, double number line, ratio table, or graph
How far does she drive in 3 hours
Answer:
1 hour= 45 miles
1/2 hour=22.5 miles
3 hours= 135
Step-by-step explanation:
just work out one hour by halving 90 miles which is 45. Then work out the rest by halving again and multiplying by 3.
Answer:
1st way:
90/2=45
1 hour = 45 miles
45/2=22.5
0.5 hour = 22.5 miles
45+22.5=67.5
1.5 hour = 67.5 miles
67.5x2=135
3 hours = 135 miles
2nd way:
90 miles - 2 hours
1 hour - 60 minutes
60x2=120
90/120=0.75
1 minute - 0.75 miles
0.75x60=45
1 hour = 45 miles
60:2=30
60+30=90
0.75x90=67.5
1.5 hour = 67.5 miles
60x3=180
0.75x180=135
3 hours = 135 miles

Answer:
y=-3x+2
Step-by-step explanation:
Slope-intercept form is given by the equation y=mx+b, where m is defined as the slope and b is defined as the y-intercept (the value on the y-axis that the line crosses). First we can determine the slope by using the slope formula.
m=(y2-y1)/(x2-x1), given two points (x1, y1) and (x2, y2). Keep in mind you can choose which point is (x1,y1) and which is (x2,y2) as long as you are consistent.
Plugging in for (-1,5) and (1,-1), you will get:
m=(-1-5)/(1-(-1))=-6/2=-3
Next, we need to find the y-intercept. For this problem, you can determine it is 2 by looking at the graph of the line. We now have both components to create the slope-intercept form.
m=-3, b=2
y=-3x+2

Step-by-step explanation:
The fee for a service call from a plumber can be modeled with the function C(h)= 75 + 20h, where C is the total cost of the service call and h is the number of hours the plumber spends working on the problem. (MAFS.912.F-IF.1.2) A. How much does the plumber charge per hour? 3. What is the value of C(3)? 1. What does this represent in terms of the problem?
Answer:
20 ; $135 ; service charge for 3 hours spent is $135
Step-by-step explanation:
Given that :
Service fee equation model :
C(h)= 75 + 20h
C = total cost of the service call
h = number of hours the plumber spends working on the problem
The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours
bx = 20h
b = 20
Charge per hour = 20
C(3) = 75 + 20(3)
75 + 60 = 135
This means that total service call charge for a plumber who spends three hours fixing a problem is $135

The slope of the line that passes through the points (5, 10) and (2, 12) is?
Answer:
[tex]\boxed{\sf m=-\cfrac{2}{3}}[/tex]
Step-by-step explanation:
In order to fins the slope we can either use the slope formula m = (y_2-y1)/(x2 – x1) or the standard line equation, y = mx + b to solve for the slope, m.
Using two points on the line, we can find the slope by finding the rise and the run
Slope formula :-
[tex]\boxed{\sf m=\cfrac{rise}{run} =\cfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf \left(x_1,\:y_1\right):\left(5,\:10\right)[/tex]
[tex]\sf \left(x_2,\:y_2\right):\left(2,\:12\right)[/tex]
[tex]\sf m=\cfrac{12-10}{2-5}[/tex]
[tex]\sf m=-\cfrac{2}{3}[/tex]
Which set of ordered pairs could represent a function? (2, 3), (2, 2), (2, 4), (2, 9), (2, –2) (1, 5), (2, 6), (1, 6), (4, 5), (1, 4) (1, 0), (2, 0), (1, 3), (4, 3), (5, 7) (5, 1), (7, 3), (9, 5), (11, 7), (13, 9)
Given:
The set of ordered pairs in the options:
(a) (2, 3), (2, 2), (2, 4), (2, 9), (2, –2)
(b) (1, 5), (2, 6), (1, 6), (4, 5), (1, 4)
(c) (1, 0), (2, 0), (1, 3), (4, 3), (5, 7)
(d) (5, 1), (7, 3), (9, 5), (11, 7), (13, 9)
To find:
The set of ordered pairs that could represent a function.
Solution:
A set of ordered pairs represent a function, if there exist unique output (y-value) for each input (x-value).
In option (a) we have, five output values y=3,2,4,9,-2 for single input x=2. So, it is not a function.
In option (b) we have, three output values y=5,6,4 for single input x=1. So, it is not a function.
In option (c) we have, two output values y=0,3 for single input x=1. So, it is not a function.
In option (d), all inputs has unique output.
Therefore, the correct option is (d).

Nathan bikes every 2 days and swims every 5 days. He biked October 2 and swam October 5th. On what day will be swim and bike on the same day? Either, the 4th, 8th, 10th, 12th, 15th, 20th.
Answer: See explanation
Step-by-step explanation:
To solve this, we have to calculate the lowest common multiple of 2 and 5. This will be:
Multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 ....
Multiples of 5 = 5, 10, 15, 20 ....
This means that he will swim and bike every 10th day together. This will be on the 10th, and 20th in October.
Answer:
On the 10th!

Write the equation of a line that is perpendicular to the given line and that passes through the
given point.
y-2= 7/3 (x + 5);(-4,9)
Oy-9=-3/7(x-4)
Oy-9= 3/7(x-4)
Oy- 9= -3/7(x+4)
Oy- 9= -3/7(x+4)
Answer:
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
Step-by-step explanation:
Slopes are negative reciprocals when two lines are perpendicular
[tex]m= - \frac {3}{7}[/tex]
Equation of straight line in point-slope form is given as
[tex]y-y_1=m(x-x_2)[/tex]
Here [tex](x_1, y_1)= (-4, 9)[/tex]
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (-4, 9).
And, The perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
Now,
Since, The equation of line passes through the point (- 4, 9).
So, We need to find the slope of the line.
Since, The product of the slope of perpendicular line is - 1.
Hence, Slope of the perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
m = dy/dx = 7/3
m = 7/3
Thus, The equation of line with slope - 3/7 is,
⇒ y - 9 = - 3/7 (x - (-4))
⇒ y - 9 = - 3/7 (x + 4)
⇒ y - 9 = - 3/7x - 12/7
⇒ y = - 3/7x + 9 - 12/7
⇒ y = - 3/7x + 51/7
Therefore, The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7
