Answer: y= - 4x+18
Step-by-step explanation:
Equation: y=mx+b
***remember: b is the y-intercept and m is the slope.
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
3= x1
2= x2
6= y1
10=y2
m=[tex]\frac{10-6}{2-3}[/tex]= [tex]\frac{4}{1}[/tex]= -4
m=-4
Now we have y=-4x+b , so let's find b.
You can use either (x,y) such as (3,6) or (2,10) point you want..the answer will be the same:
(3,6). y=mx+b or 6=-4 × 3+b, or solving for b: b=6-(-4)(3). b=18.
(2,10). y=mx+b or 10=-4 × 2+b, or solving for b: b=10-(-4)(2). b=18.
Equation of the line: y=-4x+18

If a²+b²=74 and ab=10 find the value of (a-b)²
Answer:
54
Step-by-step explanation:
(a -b)²
= a² -2ab +b²
= a² +b² -2ab
= 74 -2(10) (subst. value of a²+b² and ab)
= 74 -20
= 54

I need help finding the values of x and y!!
Answer:
x= 22
y = 35
Step-by-step explanation:
The base angles of a isosceles triangle are equal
3x-11 = 2x+11
Subtract 2x from each side
3x-2x -11 = 2x-2x+11
x-11 = 11
Add 11 to each side
x-11+11 = 11+11
x = 22
The sum of all the angles in a triangle is 180
3x -11 + 2x+11 + 2y = 180
Combine like terms
5x +2y = 180
5*22 + 2y = 180
110 + 2y = 180
Subtract 110 from each side
110+2y-110 = 180-110
2y = 70
Divide by 2
2y/2 =70/2
y = 35

Three consecutive odd numbers sum to 1,245. What are the three numbers?
Answer:
413, 415, 417
Step-by-step explanation:
Answer:
414, 415, 416
Step-by-step explanation:
Consecutive numbers means they come one after another, like 1,2,3,4,5... So they all follow the formula x, x+1, x+2, x+3...x+n.
Since there are 3, we can say that x+(x+1)+(x+2)=1,245.
Simplify that to 3x+3=1,245, and then subtract 3 from both sides.
We get 3x=1,242. Divide that by 3, and you get x=414.
Add 1 and 2 to 414, and you get 414, 415, and 416.
You can add them up to check.

If 7/9x - 4/9x = 1/4 +5/12
what is the value of x?
Answer:
x=2
Step-by-step explanation:
subtract 7/9x -4/9x
3/9x= 1/4 +5/12
first change 1/4 to 3/12
then add 3/12 + 5/12
3/9x = 8/12
change 3/9x to 1/3x then to 4/12x
4/12x = 8/12
then mulitiply by the reciprical 12/4 on both sides
x = 2

2t + 8 is greater than or equal to -4 ( t + 1 ), whats the answer to the equation?
Step-by-step explanation:
2t + 8 > - 4( t + 1)

2t + 4t < - 4 +8
6t < 4
Divide both sides by 6
T < 4
