what is the slope intercept form of (4,-3) and (2,1)
Step 1: Find the Slope
Slope Formula: (y2 - y1) / (x2 - x1)
Point 1 = (4, -3)
Point 2 = (2, 1)
Slope = (1 - - 3) / (2 - 4) = (4) / (-2) = -2
Step 2: Find the Y-Intercept
Plug in the slope and one of the points into slope-intercept form and solve for b.
Slope-Intercept Form: y = mx + b
1 = -2(2) + b
1 = -4 + b
b = 5
Step 3: Put it all together
Plug in the slope and y-intercept into slope-intercept form.
Slope-Intercept Form: y = mx + b
y = -2x + 5

9 to the power 18 = 27 to the power x work out the value of x
Answer:
Step-by-step explanation:
27^x = 9÷(3^x)
So (3^3)^x = (3^2)÷(3^x)
So 3^3x = 3^(2-x)
Comparing powers on both sides,
3x = 2 - x
So, 4x = 2
So, x = 1/2
Given ( 27 ) ^ x = 9 / 3 ^x
⇒ ( 3 × 3 × 3 )^x = ( 3 × 3 ) / 3^x
⇒ ( 3 ³ )^x = 3² / 3^x
⇒ 3 ^ 3x × 3^x = 3² [ since ( a ^m)^n = a ^mn ]
⇒ 3^ (3x +x) = 3² [ since a^m × a^n = a ^m+n ]
⇒ 3^4x = 3²
⇒4x = 2 [ since If a ^m = a ^n then m = n ]
⇒ x = 2 / 4
∴ x = 1 / 2

For what value of x is line f parallel to line g?
Answer:
13
Step-by-step explanation:
So the concept is that co-interior angles add up to 180 in parallel line. This means:
3x + 9 + 9x + 15 = 180
So we solve for x.
12x + 24 = 180 ( What I did was simplifying the equation).
12x + 24 - 24 = 180 - 24
12x / 12= 156 / 12
x = 13

The value of x is ___°, and the value of y is ___°.
Answer:
The value of x is 60°, and the value of y is 50°.
Step-by-step explanation:
50°+70°+x°=180°
x=180°-120°
x=60°
similarly the angle on the left side of x will be
70°
All these angles form 180°(linear pair)
hence, 70°+60°+y°=180°
130°+y°=180°
y°=180° - 130°
y°=50°

In class today, we had 98 notebooks and 70 children.If each child gets two notebooks, how many more notebooks will we need?
Answer:
42
Step-by-step explanation:
times 70 by two to get how many notebooks needed total.
70*2=140
subtract how many notebooks you already had.
140-98=42
The no. of notebooks we need more will be equal to 42 notebooks.
It is given that no. of notebooks available is 98 and there are 70 children in class.
We have to find no. of notebooks needed more if each child gets two notebooks.
What is algebra ?
Algebra is the branch of mathematics that deals with various symbols and the arithmetic operations and the symbols are called variables.
As per the question ;
No. of notebooks we had in class = 98 notebooks
And
Total no. of children = 70 children
The no. of notebook each child gets = 2 per child
So ;
70 children will get no. of notebooks ;
= 70 × 2
= 140 notebooks
The no. of notebooks we need will be ;
= 140 - 98
= 42 notebooks
Thus , the no. of notebooks we need will be equal to 42 notebooks.

A ride sharing company offers two options: riding in small cars that can carry up to 3 passengers each, or riding in large vans that can carry up to 6 passengers each. A group of 27 people is going to use the ride sharing service to take a trip. The trip in a small car costs $10 and the trip in a large van costs $15. The group ends up spending $80 total. An equation that represents one of the constraints is 3x+6y=a. What is the value of a?
Answer:
a = 27
Step-by-step explanation:
3x + 6y = a
From the given information, 3 and 6 are the numbers of passengers that cars and vans can take. That means x and y must be the numbers of cars and vans, and a is the total number of passengers.
a = 27
0.8% of 150 is what numbers and how do you write the equation with a variable in it.
Answer:
1.2
Step-by-step explanation:
1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: [tex]\frac{0.8}{100} * 150 = x[/tex]
2. Now, let's solve for x!
[tex]\frac{0.8}{100} * 150 = (0.008)(150)[/tex] [tex](0.008)(150) = \frac{6}{5}[/tex] [tex]\frac{6}{5} = 1\frac{1}{5}[/tex] [tex]1\frac{1}{5} = 1.2[/tex] [tex]1.2[/tex]Therefore, 0.8% of 150 is 1.2!

What is a strategy for dividing 428 by 107?
Answer:
4Step-by-step explanation:
428÷107
Use the 1 st
digit 4 from dividend 428
107)1
107)428
Since 4 is less than 107, use the next digit 2 from dividend 428 and add 0 to the quotient
107)02
107)428
Use the 2nd
digit 2 from dividend 428
107)03
107)428
Since 42 is less than 107, use the next digit 8 from dividend 428 and add 0 to the quotient
107)004
107)428
Use the 3rd
digit 8 from dividend 428
107)005
107)428
Find closest multiple of 107 to 428. We see that 4×107=428 is the nearest. Now subtract 428 from 428 to get reminder 0. Add 4 to quotient.
107)0046
107)428
107)428
107)9990
Since 0 is less than 107, stop the division. The reminder is 0. The topmost line 004 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.
Quotient: 4
Reminder: 0
