We are given the equation of a line
y = -2x + 1
We have to find the value of y at three different values of x i.e. at x =0, -3 and 1
In order to find the value of y at any given x, simply replace x by that number.
So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)
Similarly for x=-3, we get:
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)
And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y= -1
This can be expressed as an ordered pair as (-1, -1)
Answer:
Step-by-step explanation:
quadratic formula
x = -(-5)+
(2 - 2.82) ÷ 4 + 3.46
-0.82 ÷ 4 + 3.46
-.0.205 + 3.46
3.255
Im pretty sure this is correct. Correct me if I'm wrong. Hope this helps.
Answer:
<h3><u>48 people</u> is the right answer.</h3>
Step-by-step explanation:
Let the number of male and female be 3x and 5x
There are twelve more females than males
According to the above problem,

Therefore, the numbers of male is

and number of female is

Hence, total number of people are

There are <u>48 people</u> in the party.
0+a+b
a=2
b=10
0+2+10=12/3=4
4=2a
5a is the answer.
