Answer:
awnser one is 7 and question 2 is -10
Step-by-step explanation:
−12−2−−55=? question one
In the first fraction, the negative numerator and negative denominator cancel each other.
Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.
The equivalent equation is
122+55=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(12/2, 5/5) = 10
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(122×55)+(55×22)=?
Complete the multiplication and the equation becomes
6010+1010=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
60+1010=7010
Since 70 divided by 10 equals 7 then,
7010=7
Therefore:
−12−2−−55=7
Question 2
−81+6−3=?
In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.
The equivalent equation is
−81+−63=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-8/1, -6/3) = 3
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−81×33)+(−63×11)=?
Complete the multiplication and the equation becomes
−243+−63=?
The two fractions now have like denominators so you can add the numerators.
Then:
−24+−63=−303
Since -30 divided by 3 equals -10 then,
−303=−10
Therefore:
−81+6−3=−10
Solution by Formulas
Apply the fractions formula for addition, to
−81+6−3
and solve
(−8×−3)+(6×1)1×−3
=24+6−3
=30−3
=−10

Slope is 1/4 and (4,2) is on the line
Explain please also the work
Answers
Answer:
y= 1/4x -3
Step-by-step explanation:
point-slope form: y-y1=m(x-x1)
y-2=1/4(x-4)
y-2= 1/4x - 1
y= 1/4x - 3
The equation of a line in point-slope form with slope 1/4 and point (4, 2)
is y - 2 = (1/4)(x - 4).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
The equation of a line is point-slope form is y - y₁ = m(x - x₁).
Given, Slope is 1/4 and has point (x₁, y₁) = (4, 2).
∴ The equation of the given line is y - 2 = (1/4)(x - 4).

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A salad dressing recipe calls for 3⁄4 cup of olive oil for every 1⁄2 cup of vinegar.
So, For 1 cup olive oil the vinegar used
= (1/2) / (3/4)
= 1/2 x 4/3
= 2/3 cup
Now, For 2 cups of Olive oil
= 2/3 x 2
= 4/3 Cups if Vinegar used.

A function is a relationship between inputs where each input is related to exactly one output.
f(1) = 97
f(2) = 194
f(3) = 291
Where f(x) is the calories burned.
x is the number of miles walked.
Yes, the given relation in the table is a function.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
Miles walk = input
Calories burned = output
We know that,
A function can have many-to-one and one-to-one.
A function can not have one-to-many.
Now,
From the table,
f(1) = 97
f(2) = 194
f(3) = 291
We see that the relation is a function.
The relation is a one-to-one relation.
Thus,
