I am not sure which "x" you are talking about, the one for the third angle or the one in the parentheses representing another angle.
If you are wondering what the value of "x" being the third angle is, the answer is 60° since this is an equilateral triangle and all the angles are equal to 60°.
But I am pretty sure that you are looking for the value of the "x" in the parentheses. To find its value, you need to create an equation and solve it by isolating "x". Since we know that all the angles are equal to 60°, your equation should look like this :
2x - 4 = 60
Add 4 on each side of the equation
2x = 64
Divide each side of the equation by 2
x = 32
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x+7 f - 1 ( x ) = x + 7 is the inverse of f(x)=x−7 f ( x ) = x - 7 .
hope this helps.
Answer:
1) 5/7
2) (21, 5)
Step-by-step explanation:
1) The slope of the line passing through the points (7, 5) and (21, 15) is
because slope is (difference of y)/(difference of x)
the first option is correct
2) 1/3 of 5/7 is 5/21.
The line will be in the form of
y = 5/21 x + b where b is the y-intercept.
Find the complete equation by plugging in (0,0) since it passes thorugh the origin.
0 = 5/21 (0) +b
0=0+b
b=0
The equation: y=5/21 x
let's check each option by plugging in.
y= 5/21 (3)= 5/7
y is not 5 but 5/7
y= 5/21 (3)= 5/7
y is not 7 but 5/7
y= 5/21 (21) = 5
y is 5, which matches with the answer choice!!!
y= 5/21 (21) = 5
y is 5, not 7.
The third option is correct
Are you going to tell me what you meant by that? when you messaged me?
