Answer: y=3x-5
Step-by-step explanation: Find the slope of the original line. slope is m=3. Then use the point slope formula [tex]y-y1=m(x-x1)[/tex] to find the line parallel to y=3x+4. Parallel lines have the same slope. so you substitute the given point (x1,y1)(1,-2) and slope m=3 into the point slope formula.
y-(-2)=3(x-1)
y+2=3x-3
y=3x-5
Find the equation of the line which passes through the point A(2,1) and is parallel to the line 2x + 3y = 5
Answer: Find the slope of the original line and use the point-slope formula Y - Y^1 = M (X - X^1) to find the line parallel to 2 x + 3y =5
Step-by-step explanation:
Y= -2/3 x + 7/5

A car covers the distance between two cities in 6 hours. A van covers the same distance in 5.5 hours by travelling 4 km/h faster than the car. What is the distance between the two cities? Find the speed of the car and the van.
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
Given that,
A car covers the distance between two cities in 6 hours.
A van covers the same distance in 5.5 hours.
The speed of the van is 4 km per hour faster than the speed of car.
Let assume that
Speed of the car be x km per hour
So,
Speed of van is x + 4 km per hour.
Let further assume that
Distance between two cities be y km.
We know, Distance covered = Speed × Time.
➢ Now, Distance (y) covered by car at the speed of x km per hour in 6 hours is
[tex]\rm :\longmapsto\:\boxed{\tt{ y = 6x}} - - - - (1)[/tex]
➢ Also, Distance (y) covered by van at the speed of x + 4 km per hour in 5.5 hours is
[tex]\rm :\longmapsto\:\boxed{\tt{ y = 5.5(x + 4)}} - - - - (2)[/tex]
So, from equation (1) and (2), we have
[tex]\rm :\longmapsto\:6x = 5.5(x + 4)[/tex]
[tex]\rm :\longmapsto\:6x = 5.5x + 22[/tex]
[tex]\rm :\longmapsto\:6x - 5.5x = 22[/tex]
[tex]\rm :\longmapsto\:0.5x = 22[/tex]
[tex]\rm :\longmapsto\:\dfrac{5}{10} \times x = 22[/tex]
[tex]\rm :\longmapsto\:\dfrac{1}{2} \times x = 22[/tex]
[tex]\bf\implies \:x = 44[/tex]
On substituting the value of x, in equation (1), we have
[tex]\rm :\longmapsto\:y = 6 \times 44[/tex]
[tex]\bf\implies \:y = 264[/tex]
So,
[tex]\begin{gathered}\begin{gathered}\bf\: \rm :\longmapsto\:\begin{cases} &\sf{Distance \: between \: cities = 264 \: km} \\ \\ &\sf{Speed \: of \: car \: = \: 44 \: km \: per \: hour}\\ \\ &\sf{Speed \: of \: van \: = \: 48 \: km \: per \: hour} \end{cases}\end{gathered}\end{gathered}[/tex]

After running
7/8 mile in a horse race, a horse ran an additional 3/8 mile to cool down. How far did the horse run altogether?
Answer:
1 2/8 (simplified 1/4)
Step-by-step explanation:
Well indicating that you have to add
7/8+3/8
7+3= 10
don't add the bottom numbers
10/8 simplify that
1 2/8
simplify
2/8, which is 1/4
Gives you the answer of
1 1/4
Answer:
1 1/4
Step-by-step explanation:
[tex]\frac{7}{8}+\frac{3}{8} = \frac{10}{8}= 1\frac{2}{8}divided by 2 = 1\frac{1}{4}[/tex]

hello,i need help with this question:
The sum of the measures of angle M and angle R is 180⁰.
• The measure of angle M is (5x+10)⁰.
• The measure of angle R is 55⁰.
What is the value of x?
☺
Answer:
x = 23
Step-by-step explanation:
If the sum of angles is equal to 180 then we can write and equation to find the value of x
5x + 10 + 55 = 180 add like terms
5x + 65 = 180 subtract 65 from both sides
5x = 115 divide both sides by 5
x = 23

Perform the indicated operations. Reduce your answer to it's lowest term.
Step-by-step explanation:
15 1/2+ 3/4=16 1/4
to add fractions what you want to do is this:
so you want them as the same denominator, a way to do this is multiply one denominator with another (ex, 2 in 1/2. you want to multiply 4 with 2 which equals 8 and 2 with 3. this together equals 6/8. do the same thing with 1/2. 1×4=4 2×4=8. 4/8)
so, whats 4/8 and 6/8? just adding it like usual, it'll be 10/8, or 1 2/8.
15+1 2/8=16 2/8
16 2/8 simplified (just divide by 2 until you make it to where you cant anymore)
16 1/4
do the same with the other adding ones.
23 1/6+8 3/4=23 11/12
15 2/5+ 2 2/6= 17 11/15
now, do the same way as showed before but except subtract.
9/10 - 3/5 = 15/50
7 3/4 - 5 5/8 = 1/8
20 5/8= 1/8

The Equation of line u is y =-8/9x+5/4. The equation of line v is y =9/8x+7/4. Are line u and line v parallel or perpendicular?
Answer:
when two lines are parallel the two slopes are equal (m1 =m2)
when two lines are perpendicular the product of the slopes is equal to -1( m1m2= -1)
m1 =1st slope
m2= 2nd slope
using the formula y= mx +c
m1= -8/9
m2= 9/8
since m1 is not equal to m2 and -8/9 × 9/8 = -1
It is perpendicular

To win a trivia game, Nevan must score 90 points. Each correct
answer is worth 1 3/4 points, and each incorrect answer is worth
- 1/4 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?
Answer:
Nevan does not win
He scored 74 points
Step-by-step explanation:
First, find how many points he gets from 58 correct questions:
Multiply 1 3/4 by 58:
58(1.75)
= 101.5
Then, find how many points he loses from 22 incorrect questions:
Multiply -1 1/4 by 22:
22(-1.25)
= -27.5
Then, subtract 27.5 from 101.5 to find how many points he scored:
101.5 - 27.5
= 74
Since he needed 90 points to win, he did not win because he only got 74.

Franklin starting playing video games as soon as he got home from school. He played video
games for 54 minutes. Then Franklin helped clean the kitchen for 1 hour. After the kitchen
was clean, it took Franklin 57 minutes to finish his homework. wWhen Franklin finished his
homework, it was 5:56 P.M. What time did Franklin get home from school?
Answer:
3:05
Step-by-step explanation:
Answer: he got home at 3:05 pm!
Step-by-step explanation:
working backwards from the time stamp 5:56pm, we can just subtract the time he spent gaming and doing chores:
5:56
-0:54 mins games
-1:00 cleaning
-0:57 for homework= the time he got home, but lets make it easier!
54+57=111, in total, that's 1:51 time wise, so that simplifies it a little, be we can simplify it further, by adding the hour spent cleaning.
1:51 on homework n games + 1:00 on cleaning = 2:51 spent on home stuff in general
so lets go back to our subtraction:
5:56 pm -time stamp after all his chores
-2:51 spent on home stuff
= 3:05 pm the time he left school
Each year a certain amount of money is deposited in an account which pays an annual interest rate of so that at the end of each year the balance in the account is multiplied by a growth factor of x = 1 + r. $300 is deposited at the start of the first year, an additional $500 is deposited at the start of the next year, and $400 at the start of the following year.

What is 1/10=4/5y ?????
Answer:
y = 1/8
Step-by-step explanation:
Divide both sides by 4/5, 1/10 divided by 4/5; 4/5y divided by 4/5. In 4/5y divided by 4/5, the two 4/5s cancels out, leaving y alone. 1/10 divided by 4/5 equals to 1/8. Now you have, 1/8 = y, which is the same thing as y = 1/8. Therefore, the value of y is 1/8.
Answer: 1/8
Step-by-step explanation:
4/5y=1/10
*multiply both sides by 5, and you'll get
4y=1/2
*divide both sides by 4
y=1/8

Answer:
See below.
Step-by-step explanation:
First question:
Think of the x-axis as a mirror. Quadrilateral is above the x-axis. Quadrilateral is below the x-axis. Quadrilateral ABCD was reflected across the x-axis. Quadrilateral A'B'C'D' is a mirror image of quadrilateral ABCD.
Quadrilateral ABCD undergoes a reflection across the x-axis to form quadrilateral A'B'C'D'.
Second question:
Quadrilaterals ABCD and A"B"C"D" are both turned the same way. Quadrilateral A"B"C"D" is just moved left and down from quadrilateral ABCD. That transformation is called a translation.
Quadrilateral ABCD undergoes a translation 7 units left and 1 unit down to form quadrilateral A"B"C"D".
