what is an equation that passes through -1,2 and is parallel to the point 3x+y=3 ?
Answer:
y=3x+5
Step-by-step explanation:
For this you can use the point-slope formula: y-y1=m(x-x1). Since the line we're looking for is parallel, both slopes are equivalent.
First, you have to rewrite the primary equation into standard form, which would rewrite to y=3-3x or y=-3x+3. Then, you can use the information we have in the point-slope formula:
y-(2)=3(x+1)
y-2=3x+3
y=3x+5
Check:
(2)=3(-1)+5
2=-3+5
2=2

In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 51°F and the low temperature for the same day was 45°F, what is the number of heating degree days? A. 17 B. 48 C. 113 D. 14
Given that,
The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.
Solution,
The high temperature was 51°F and the low temperature was 45°F.
Average of high and low temperatures for the day is given by :
[tex]T=\dfrac{51+45}{2}\\\\T=48^{\circ} F[/tex]
Now using formula :
H = 65 - T
H = 65 - 48
H = 17
Hence, there are 17 heating degree days.

Victoria filled up her car with gas before embarking on a road trip across the country. The car uses 1.75 gallons of gas for every hour driven, and after driving for 4 hours, there were 7 gallons of gas left in the tank. Write an equation for G,G, in terms of t,t, representing the number of gallons of gas remaining in Victoria's gas tank after tt hours of driving.
Answer:
G = 14 - 1.75(t)
Where G is the number of gallons of gas remaining;
14 represents the amount of gas in gallons in the full gas tank of the vehicle
t is the number of hours
Step-by-step explanation:
Here, we want to write an equation.
We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left
In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons
So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons
Hence, the equation we want to write will be;
G = 14 - 1.75(t)

Which is true of the slopes of parallel lines
Answer: slopes will be the same!
Step-by-step explanation:
Answer:
In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other. Here is a quick review of the slope/intercept form of a line

work:
3/2 + 2m = 7/2
3/2 (-3/2) + 2m = 7/2 (-3/2) subtract 3/2 from both sides
2m = 2
2m/2 = 2/2 divide 2 on both sides
m = 1
The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; "5" /"8" of them are seventh graders and "3" /"8" of them are eighth graders. If "4" /"5" of the seventh graders participated in track-and-field day and "7" /"8" of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Given that, the total number of students in seventh and eighth grade combined is 584.
The number of students in seventh grade= 5/8 of the total number of students.
[tex]=\frac 5 8 \times 584=365[/tex]
As 4/5 of the total seventh-grade students participated in the track-and-field-event.
So, the number of seventh-grade students participated
[tex]= \frac 4 5 \times 365=292[/tex]
The number of students in the eighth grade 3/8 of the total number of students.
[tex]=\frac 3 8 \times 584=219[/tex]
As 7/8 of the total eighth-grade students participated in the track-and-field-event.
So, the number of seventh-grade students participated
[tex]= \frac78 \times 219=191.625.[/tex]
The number of students must be a counting number, but here, as per the given information, the number of seventh-grade students participated coming out a fractional number, so the given information is incorrect.
Although, as per the given data, the mathematical value of the total number of students participated from both the grade combined
=292+191.625
=483.625 (mathematically)
Again, in real life, the fractional value of the total number of students is not possible.
Answer:
Given that, the total number of students in seventh and eighth grade combined is 584.

Linda has had three music lessons this month. They have been on May 3, May 10, and May 17. What date do you think she will have her next music lesson?
Answer:24
Step-by-step explanation:
Each is 7 days a part she dose it every week so just add 7
Answer:
May 24
Step-by-step explanation:
May 3 to May 10 is 7 days or one week
May 10 to May 17 is one week
Linda probably has music lessons every week on the same day
May 17 + one week, or 7 days = May 24
Let cos(2x) - cos(x) = 0 where 0° < x <180° what are the possible values of x
Answer:
x= 120°
Step-by-step explanation:
cos(2x)-cos(x)=0
[tex]\Rightarrow 2\cos^2x-\cosx-1=[/tex]0 [as [tex]\cos(2x)=2\cos^2x-1[/tex]]
[tex]\Rightarrow 2\cos^2x-2\cosx +\cosx-1=0[/tex]
[tex]\Rightarrow 2\cos x(\cos x-1) +(\cos x-1)=0[/tex]
[tex]\Rightarrow (\cos x-1)(2\cos x +1)=0[/tex]
[tex]\Rightarrow \cos x-1=0 \;or\; 2\cos x +1=0[/tex]
[tex]\Rightarrow \cos x=1 \;or\; \cos x =-1/2[/tex]
[tex]\Rightarrow x=\cos^{-1}1 \;or\; x =\cos(-1/2)[/tex]
For [tex]x=\cos^{-1}1[/tex] and 0° < x <180°
There is no possible value of x.
For [tex]x =\cos(-1/2)[/tex] and 0° < x <180°
The possible value of x is
x= 120°

Debbie's backyard deck cost $56.00 per square meter to build. The deck is 9 meters wide and
9 meters long. How much did it cost to build the deck?
Answer:
$514.00
Step-by-step explanation:
56 x 2 = 112
112 x 4 = 448
448 + 56 - 514
so $514.00 is your answer.

como resolver a equação -7. (x-3)=x +5
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
[tex]-7(x-3)=x+5[/tex]
Distribute the [tex]-7[/tex] into [tex](x-3)[/tex]:
[tex]-7x+21=x+5[/tex]
Subtract [tex]x[/tex] from both sides of the equation:
[tex]-8x+21=5[/tex]
Subtract [tex]21[/tex] from both sides of the equation:
[tex]-8x=-16[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-8[/tex]:
[tex]x=2[/tex]
_
Check your work by substituting [tex]2[/tex] into the initial equation:
[tex]-7(2-3)=2+5[/tex]
[tex]-14+21=2+5[/tex]
[tex]7=7[/tex]
The answer is correct!

For which value of x is the function 2x^2 + 3x + 1/x - 1 g(x) undefined?
Answer:
See below
Step-by-step explanation:
We have
[tex]g(x)=2x^2 + 3x + \dfrac{2}{x} - 1[/tex]
The function is true [tex]\forall x \in\mathbb{R}[/tex] except 0, because division by zero is undefined.
Therefore, the domain of the function can be written as
[tex]Dom(g) = \mathbb{R}-\{0\} \text{ or } (-\infty, 0)\cup (0, \infty)[/tex]

Nicole bought 6 tickets to an indoor water park. She paid a 6% service charge for buying them online. Her total cost was
$165.36
a What equation can be used to model the total cost of the tickets?
6. What was the price of each ticket?
C. How much did Nicole pay in service charges?
Answer:
Step-by-step explanation:
Let each ticket cost x
Answer for Part A
6x + 6% (6x) = 165.36 dollars.
Answer for Part B
6x + 6/100 * 6x = 165.36
6x + 36/100 x = 165.36
6x + 0.36 x = 165.36
6.36x = 165.36
x = 165.36/6.36
x = 26 dollars for each ticket.
Part C
Service charge = 165.36 - 6*26
Service charge = 165.36 - 156
Service charge = 9.36
