The equation of the linear function in slope intercept form is f(x) = -2x + 1
How to represent function in slope intercept form?The table can be used to write linear equation in slope intercept form.
Therefore, the equation of the linear function in slope intercept form is as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore,
m = 3 - 5 / -1 + 2
m = - 2 / 1
m = -2
Therefore, the y-intercept can be solved as follows;
using (0, 1)
y = -2x + b
1 = -2x + b
1 = -2(0) + b
b = 1
Hence, the the equation of the linear function in slope intercept form is f(x) = -2x + 1

Answer:
[tex]6 - (5 \times x) = 31[/tex][tex]5 \times x + 7 = 27[/tex]angle POR and angle ROQ from linear pair . If a-b=
[tex] {80}^{0} [/tex]
find the value a and b .
Answer:
a = 130
b = 50
Explanation:
Analyze that the angles a and b lies on a straight line summing up to 180°.
Equation's:
a + b = 180 ____eq 1a - b = 80 ____eq 2make 'a' subject in eq 1
a + b = 180
a = 180 - b
substitute this into eq 2
a - b = 80
(180 - b) - b = 80
180 - 2b = 80
-2b = 80 - 180
-2b = -100
b = 50
Find value of 'a':
a = 180 - b
a = 180 - 50
a = 130
Answer:
a = 130°, b = 50°
Step-by-step explanation:
The given equation is,
→ a - b = 80°
→ a + b = 180°
The equation we form is,
→ (a + b) + (a - b) = 180 + 80
Now the required value of a will be,
→ (a + b) + (a - b) = 180 + 80
→ (a + a) + (b - b) = 260
→ 2a = 260
→ a = 260/2
→ [ a = 130° ]
Hence, the value of a is 130°.
Then the required value of b will be,
→ a + b = 180
→ 130 + b = 180
→ b = 180 - 130
→ [ b = 50° ]
Hence, the value of b is 50°.
select all numbers in which the place value of the digit 6 is equal to 1/10 of the place value of the digit 6 in the number 760.000
The place value of the digit "6" in the given number 760,000 is Ten thousand's i.e., sixty thousand.
Definition of place value
The numerical value of the digit in the given number is based on its position in the number.

newaye is making a salt solution. the instructions ask for 0.07 kilograms of salt to be added to every liter of water. how much salt should he use if he wants to make a solution with 0.5 liter of water
Answer:
0.035 kg
Step-by-step explanation:
(0.07 kg / 1 litre) x (0.5 litre)
= 0.035 kg
Notice how the units of litres cancel and all you are left with is units of kg which is what we want. Another way of solving this problem is via logic. If 1 litre of water is needed for 0.07 kg salt, then half a litre of water (0.5) would need half of the amount needed by 1 litre water so (0.07/2) = 0.035 kg

Ann and Ben translate documents from German into English.
A set of documents that would take Ann 10 days would take Ben 12 days
Ann starts to translate the documents.
After 2 days Ann and Ben both work on translating the documents.
How many more days will it take to complete the work?
they will approximately require 4.4 days to complete the remaining work together.
Ann alone take = 10 days to translate a document.
Work done in 1 day by Ann = 1 / 10
In 2 days = 2 / 10
Work left = 8 / 10
Now, Ben alone take = 12 days to translate a document.
Work done in 1 day by Ben = 1 / 12
We will now use addition.
Combined work of both Ann and Ben in 1 day = 1 / 10 + 1 / 12 = 11 / 60
Time taken to complete the rest of the work = 8 / 10 ÷ 11 / 60
= 48 / 11 = 4.4 days.
Therefore, they will approximately require 4.4 days to complete the remaining work together.

Solve for y
Answer:
y = mX - mx
Step-by-step explanation:
X - (y/m) = x
Multiply everything by m
(m)X - (y/m)(m) = x(m)
mX - y = mx

-y = mx - mX
Divide both sides by -1
-y = mx - mX
÷ -1 ÷ -1
y = -mx + mX

Given the quadratic function g(x)=

which of the following could be a factor of g (x)? More than one can apply.
a. (2x-1) b. (x+3) c. (x-3) d. (2x+3)
we get that option (d) 2 x + 3 is a factor of the quadratic function g (x)= a x² - 7 x - 15.
We are given a quadratic function:
g (x)= a x² - 7 x - 15
We also know that 5 is a root for it.
So, we get that:
a (5)² - 7 (5) - 15 = 0
25 a - 35 - 15 = 0
25 a - 50 = 0
25 a = 50
a = 50 / 25
a = 2
So, the function becomes:
g (x)= 2 x² - 7 x - 15
Now factorizing the function:
2 x² - 7 x - 15
2 x² - 10 x + 3 x - 15
2 x ( x - 5 ) + 3 ( x - 5 )
( 2 x + 3 ) ( x - 5 )
Therefore, we get that option (d) 2 x + 3 is a factor of the quadratic function g (x)= a x² - 7 x - 15.

one number is 4 times a first number. a third number is 100 more thann the first number. if the sum of the three numbers is 562, find the numbers
The numbers are 77 , 177 and 308 .
Numbers are the building blocks in mathematics. It is an arithmetic value that is used to represent a quantity. Real numbers , integers , natural numbers, whole numbers , irrational numbers are are various types of numbers.
Let us consider the first number to be x . Then the second number is 4x+100 , and the third number is 100 more than the first number. Therefore the the sum of the three numbers will be:
x+4x+(x+100)=6x+100
Now the sum of all the numbers is 562.
Therefore we can write a linear equation in x to find the values of x.
∴ 6x+100=562
or, 6x = 562 - 100
or, 6x = 462
or, x = 462 ÷ 6
or, x = 77
Therefore the second number is 4x = 4 × 77 = 308 and the third number is x + 100 = 77 + 100 = 177 .
So the numbers are 77 , 177 and 308 .
