Hint :- The point slope form of the line is [tex] m(x-x_1) = y - y_1[/tex] , where [tex](x_1,x_2)[/tex] is the point and [tex] m [/tex] is the slope of the line .
Solution :- The given point is [tex](2,-1)[/tex] and the slope is 3 . On using the point slope form of the line, we have ;
[tex]\implies m(x-x_1)=y-y_1[/tex]
Substitute ,
[tex]\implies 3(x -2) = y -(-1) [/tex]
Simplify ,
[tex]\implies 3x -6=y+1 [/tex]
Add -1 and -y to the both sides ,
[tex]\implies \boxed{3x -y -7=0 }[/tex]
Find the value of x.
Answer:
[tex]x = 88[/tex]
Step-by-step explanation:
the degrees of a triangle = 180. write an equation adding the angle measures given
[tex]48 + x - 44 + x = 180[/tex]
collect like terms on the left
[tex]2x + 4 = 180[/tex]
subtract 4 from both sides
[tex]2x = 176[/tex]
divide both sides by 2
[tex]x = 88[/tex]

What is the range of the function f(x) = 3x + 2
when the domain is {-2,-1,2}?
Answer:
Im going to give them as ordered pairs, you can pick out the range (Y values): (-2,-4), (-1,-1), (2,8)
Step-by-step explanation:
All that needs to be done for this problem is one thing: substitute the given domain values for the "x" in the equation. Domain is just a fancy way of saying x coordinate. All f(x) is is "function of x." This can still be your Y coordinate, or your range. I hope this process helps!

what is the slope?
Answer:
2/3
Step-by-step explanation:
Find a two coordinates on the line such as (20,40) and (50,60)
plug it into the slope formula m= y2 - y1 / x2- x1
it doesn't matter what way you plug them in
m = slope
m = 60-40 / 50 - 20 = 20/30 = 2/3
The slope is 2/3 I simplified 20/30 by dividing by 10

Step-by-step explanation:
The relation between angle DCF and CFG is co-interior angles, or same side interior angles.
Angle(DCG+CFG)=180
Measure of DCF=180-3x=147 [Because Angle DCF+ACD=180, Angles in a straight line]
Measure of CFG=180-6x-81=33 [Because AngleCFG+HFG=180, Angles in a straight line]
Which graph represents the solution to this system of inequalities?
y<-x-3
y> 2x-4
(Please set graph in 10x10 scale)!!(:
Answer:
Heres your answer graphed
Step-by-step explanation:
Please help me solve this ASAP
Answer:
look below
Step-by-step explanation:
going left and right changes the x( first number in each parentheses)
going up and down changes the y (second number in parentheses)
going to the left by 9 means all the first numbers are going in the negative direction (-9)
going up by 12 means the second numbers are going in the positive direction (+12)
take all x values and add -9, take all y values and add 12
X (-15, 13)
Y(-5,12)
Z(-8, 15)

Answer:
x=24°
Step-by-step explanation:
(3x-6)°+x°= 90°
4x=90+6
4x= 96°
x= 24°
Answer:
Step-by-step explanation:
(3x-6)°+x°=90°
First, combine like terms:
3x°+x°-6°=90°
4x°-6°=90°
Add 6° to both sides:
4x°=96°
Divide 4 from both sides to isolate x:
x=24°
Check your answer:
3(24)-6+(24)=90°
72-6+24=90°
66+24=90°
90°=90° (correct)
