Answer:
-3
Step-by-step explanation:
if ay=bx+c , then the slope is b/a
I have 1*y=-3*x+1, the slope is -3/1=-3
Or
the slope is y2-y1/x2-x1
if x1=1 ,y1= -3*1+1=-3+1=-2
x2=2, y2=-3*2+1=-6+1=-5
the slope is (y2-y1)/(x2-x1)=(-5+2)/1=-3
10y + 7 + 2x I don't know if that's an equvalent expression though
Answer:
- The angle ∠2 = 4x = 4(36°) = 144°
Step-by-step explanation:
We know that when two lines meet or intersect, we get a linear pair of angles.
Linear pairs are basically two adjacent angles that form a line.
The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.
We are given that <1 and <2 forms a linear pair, and
m∠1 = 4m∠2
It means the angle ∠1 is 4 times the measure of angle ∠2.
Let the angle ∠1 be = x
As the angle 1 is 4 times the measure of angle ∠2, so
The angle 2 will be = 4x
As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so
x + 4x = 180
5x = 180
divide both sides by 5
5x/5 = 180/5
x = 36°
Therefore,
- The angle ∠2 = 4x = 4(36°) = 144°
The only order pairs among the given options that represent a function is :
- (9 , -3) , (9 , -1) , (9 , -1)
Because : To be a function, every element of domain (x) can have only one unique value y, and if we get more than two values of y for same x, it isn't a function at all.
The algebraic expression for twice difference of a number (n) and 6 is expressed algebraically as, 2(n - 6).
<h3>What is an Algebraic Expression?</h3>
An algebraic expression can be used to model word problem or a situation with the use of variables, operation signs and numbers.
Difference is minus (-)
Let n represent the unknown number.
Thus, twice difference of a number (n) and 6 is expressed algebraically as, 2(n - 6).
