Answer:
m=slope y = intercept
m= y2-y1 / x2-x1
2-1 / 2-0 = 1 /2
now pick one of the points and put in for y and x
use (2,2) 2= 1/2(2) +b
2=1 + b
2-1 =1-1 +b subtract 1 from each side
1 = b This is your y intercept
Step-by-step explanation:
The equation of the line passing through points (0,1) and (2,2) will be y = ( 1 / 2) x + 1
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope= 2-1 / 2-0 = 1 /2
Now pick one of the points and put in for y and x use (2,2).
2= 1/2(2) +b
2=1 + b
2-1 =1-1 +b subtract 1 from each side
1 = b This is your y-intercept
The equation will be written as:-
y = ( 1 / 2) x + 1
Therefore, the equation of the line passing through points (0,1) and (2,2) will be y = ( 1 / 2) x + 1.

c=116
d=59
A is 57 because the lines are parallel and alternate interior angles. B is 64 because the lines are parallel and alternate interior angles. C is 116 because of linear pair. 180 - 64(b). D is 59 because of triangle sum theorem. Sum of measures of all angles in a triangle equal 180
Calculate the product 78.93 x 32.45
Answer:
The answer is 2 561,2785 !!!
The required value is 2,556.2785 which is determined by the multiplication operation.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
The numbers are given in the question, as follows:
78.93 and 32.45
To calculate the product of 78.93 and 32.45, you can use the standard multiplication algorithm.

D. m2 2 + m23 = 80°
Answer:
A is answer
Step-by-step explanation:
please follow me
Answer:
B and C
Step-by-step explanation:
Since m and n are parallel, we can call the two lines extending from the point B transversals.
[tex]m\angle{1} = 60^\circ[/tex] because they are vertical angles
[tex]m\angle{2} = 20^\circ[/tex] from the corresponding angles theorem.
[tex]m\angle{4} = 60^\circ[/tex] from the corresponding angles theorem.
[tex]m\angle{3} = 100^\circ[/tex] because angle 2 and 4 sum to 80, and [tex]m\angle{2} + m\angle{3} + m\angle{4} = 180^\circ[/tex] because it is a straight angle.
From this, we can see which ones are true.
A is false because angle 2 is 20 degrees.
B is true because angle 3 is 100 degrees.
C is true because angle 2 + angle 4 = 20 + 60 = 80 degrees.
D is false because angle 2 + angle 3 = 20 + 100 = 120 degrees.
Therefore, only B and C are true.

Rewrite the equation so that it does not have any fractions
Answer:
24+9x=5
Step-by-step explanation:
First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.
2*12=24,
3/4*12=36/4=9,
5/12*12=60/12=5.
Using these values will give your final equation: 24+9x=5

At the restaurant, the cost of the meal before tax was
$40. The tax is 8.5%, and Sheri wants to leave at least
an 18% tip. Explain how to approximate the total cost of
the meal.
Answer:
so you add then multiply then subtract
Step-by-step explanation:
Answer:
First we estimate the percent's. 8.5% - 10%, 18% - 20%. Then we do the equation. If you add percent's you get 30% multiply that by 40 and you get 12. Add that to you problem and you get $52.
Step-by-step explanation:
Since the tax and gratuity were 4 and 8 dollars you can just add those up to the 40, but I did it another way.
This is the sample response if you want a better explanation.
The gratuity is about 20% of $40, which is $8. The tax is about 10% of $40, which is $4. So, the total cost is about $40 + $8 + $4 = $52.
