Answer:
Slope and y intercept.
Step-by-step explanation:
This is necassary to write the equation of a line in y=mx+b
m is where the slope goes, and b is the y intercept.
Alternatively, you could also write the equation for a line with a point on the line and the slope.
You would then write it in point slope formula:
y-y1=m(x-x1)
This can later be converted into slope intercept form.
Answer:
When asked to write an equation, you need to know two things – slope (m) and y-intercept (b).
Or
The Standard Form for a linear equation in two variables, x, and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

4.1271 to the nearest cent?!
Answer:
4.1271
Step-by-step explanation:
Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.
4.1271
last number is 1 so the cents stays the same
6x2 + 6x – 1= -5x – 4
Answer:
x= -1/3 or x= -3/3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x2+6x−1=−5x−4
Step 1: Subtract -5x-4 from both sides.
6x2+6x−1−(−5x−4)=−5x−4−(−5x−4)
6x2+11x+3=0
Step 2: Factor left side of equation.
(3x+1)(2x+3)=0
Step 3: Set factors equal to 0.
3x+1=0 or 2x+3=0
x= -1/3 or x= -3/3
The value of 8 units is 11. What is the value of 1 unit
Answer:
1.375
Step-by-step explanation:
11 divided by 8 = 1.375
A proportion is an equation in which two ratios are set equal to each other. Then the value of 1 unit is 1.375.
What is a ratio?
A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0.
The value of 8 units is 11.
Then the value of 1 unit will be
The value of 8 units is 11.
Then the value of the 1 unit will be 11/8.
That can be solved as
[tex]\dfrac{11}{8} = 1.375[/tex]
Thus, the value of 1 unit is 1.375.

Step-by-step explanation:
✔️Gradient for line A using two points on line A, (0, 1) and (1, 3):
[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 1}{1 - 0} = \frac{2}{1} = 2 [/tex]

Samantha wants to hang 3 paintings in her room. The widths of the paintings are 10+*inches, 3+*feet, and 2 feet, 2),inches. If she hangs them next to each other with 3 inches between them, what is the total width of the wall space she will need?
Answer:
78 inches
Step-by-step explanation:
From the above question, our final answer is in inches, hence:
1 foot = 12 inches
The widths of the paintings are 10+*inches, 3+*feet, and 2 feet, 2),inches.
For painting 2
Converting 3 feet to inches
1 foot = 12 inches
3 feet = x
Cross Multiply
x = 3 × 12 inches = 36 inches
For painting 3
2 feet, 2,inches.
Converting 2 feet to inches
1 foot = 12 inches
2 feet = x
Cross Multiply
x = 2 × 12 inches = 24 inches
Adding up = 24 inches + 2 inches = 26 inches
If she hangs them next to each other with 3 inches between them, what is the total width of the wall space she will need?
This is calculated as:
10 inches + 3 inches + 36 inches + 3 inches + 26 inches
= 78 inches
Therefore, the total width of space she will need = 78 inches

(A journey by bus takes 45 minutes at 60 km per hour. How fast must a car go to do the same
journey in 25 minutes? plzz answerr!!! this is my third time asking this question:(
Answer:
The car must go at 108 km per hour
Step-by-step explanation:
Let us solve the question
∵ A journey by bus takes 45 minutes at 60 km per hour
∴ The speed of the bus = 60 km per hour
∴ The time of the journey = 45 minutes
→ Change the time from minutes to hours
∵ 1 hour = 60 minutes
∴ 45 minutes = 45 ÷ 60 = 0.75 hour
∴ The time of the journey = 0.75 hour
∵ Distance = Speed × Time
→ Substitute the speed by 60 and the time by 0.75
∵ The distance that the bus traveled = 60 × 0.75
∴ The distance that the bus traveled = 45 km
∵ A car goes to do the same journey in 25 minutes
∴ The distance that the car travels = 45 km
∴ The time that the car takes = 25 minutes
→ Divide it by 60 to change it to hours
∵ 25 minutes = 25 ÷ 60 = [tex]\frac{5}{12}[/tex] hour
∴ The time that the car takes = [tex]\frac{5}{12}[/tex] hour
→ Use the rule of the distance above to find the speed of the car
∵ 45 = the car's speed × [tex]\frac{5}{12}[/tex]
→ Divide both sides by [tex]\frac{5}{12}[/tex]
∴ 108 = the car's speed
∴ The car's speed = 108 km per hour
∴ The car must go at 108 km per hour
