write an equation for the line above
Answer:
y= -3x/5
Step-by-step explanation:
y=mx+b where m is the slope and b is the y-intercept
m= rise/run = -3/5 (go from one point to the other on the graph)
y-intercept is (0,0)
Will give 20 points if you answer correctly, will give brainliest! Please answer and EXPLAIN! Thanks
write the slope intercept form of an equation of the line that passes through the given point and is parallel to the graph of the equation (-3,5), y=-5x+3
a. y= 10x-5
b. y=-5x-10
c. y=-5x+10
d. y+1/5x-5
Please help! Thx!
Answer: B
Step-by-step explanation:
so for the slope to be parallel, it means it's the same slope as the given equation which is -5
using point slope, we can write a new equation
y -5 = -5(x+3)
y -5 = -5x-15
y = -5x-10

a typical car releases 36 tons of carbon dioxide and six years at a constant rate how many times will a car release in 10 years ?
Answer:
60 Tons
Step-by-step explanation:
36 divided by 6 equals 6. So that six is used for the for extra years
36+6+6+6+6
The number of tonnes of carbon dioxide released in 10 years will be 60 tonnes.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A typical car releases 36 tonnes of carbon dioxide and six years.
Let 'x' be the amount of carbon dioxide.
At a constant rate, the number of tonnes of carbon dioxide released in 10 years will be given as,
x / 10 = 36 / 6
Simplify the equation, then we have
x / 10 = 36 / 6
x / 10 = 6
x = 60 tons
The number of tonnes of carbon dioxide released in 10 years will be 60 tonnes.

Your school band is performing a concert. Tickets cost $3 for students and $5 for adults. A total of 125 people attended the concert for a total ticket sales of $475. Write and solve a system of equations to find the number of students and adults that attended the concert. Make sure to write your answer in a complete sentence.
Given :
Tickets cost $3 for students and $5 for adults.
A total of 125 people attended the concert for a total ticket sales of $475.
To Find :
The number of students and adults that attended the concert.
Solution :
Let, number of students and adults that attended the concert is x and y.
Mathematical equation of given conditions :
x + y = 125 ....1)
3x + 5y = 425 ....2)
Putting value of x from 1 to equation 2 is :
3( 125 - y ) + 5y = 425
375 - 3y + 5y = 425
2y = 50
y = 25
x = 125 - 25
x = 100
Therefore, number of students and adults that attended the concert is 100 ans 25 respectively.
Hence, this is the required solution.

We can clearly see in the diagram that a transversal is intersecting two parallel lines.
When a transversal intersects two parallel lines, eight angles are formed.
The angles which are in the same position on same side of each line intersected by the transversal, are called corresponding angles.
Corresponding angles are congruent.
So,
Angle 6x+4° and 100° will be congruent or equal
[tex]6x+4 = 100\\6x =100-4\\6x = 96\\\frac{6x}{6} = \frac{96}{6}\\x = 16[/tex]
Hence,
The value of x is 16

675 grams of sweets were distributed among 9 children. How much sweet was given to each child?
Answer:
75 Sweets
Step-by-step explanation:
To get the answer you have to divide the number of sweets by the number of children. If there are 675 grams and 9 children, then you divide 675/9 to get your answer of 75 sweets.
Each child was given 75 grams of sweets as per linear equation when distributed.
What is a linear equation?A linear equation is an equation where the highest degree of the variable is one.
Given, there are a total of 675 grams of sweets.
There are a total of 9 children among which the sweets is to be distributed equally.

A scooter travels 30 feet in 2 seconds at a constant speed.
What is the speed of the scooter in feet per second?
Answer:
15
Step-by-step explanation:
Since it goes 30 in 2 seconds, we need to divide 30 and 2 and end up with 15.
To make sure our answer is correct we know that 15 is one second, so we can add 15+15= which will give us 30, and will also land at 2
Brainliest pls
The speed of the scooter is 15 feet per second.
To calculate the speed of the scooter in feet per second, you can use the formula:
Speed = Distance / Time
The distance traveled by the scooter is 30 feet, and the time taken is 2 seconds.
Plugging these values into the formula, we get:
Speed = 30 feet / 2 seconds
Speed = 15 feet/second
Therefore, the speed of the scooter is 15 feet per second.
