Answer:
-120 degrees.
Step-by-step explanation:
This triangle has a rotational symmetry of 3 (it repeats its orientation 3 times as it makes a complete circle around the center), so the angle of rotation is 360 / 3 = 120 degrees.
As the rotation is counter clockwise strictly speaking the answer is -120 degrees.
Answer: b= - -log10(7)+3/2
Step-by-step explanation: log 10 (7) -2b-9=-6 : b= - -log10(7)+3/2 (Decimal : b = -1.07745...)
so these are the steps how I got it I did log 10 (7)-2b-9=-6 subtract log 10 (7) -9 from both sides log 10 (7)-2b-9-(log10(7)-9)=-6-(log 10 (7) -9)
Simplify -2b= -log10(7)+3
Divide both sides by -2 -2b/2= - log 10(7)/-2+ 3/-2 if you simplify it should give you b= - -log10(7)+3/2 that should be your answer but i'm not sure those I think that's how you do it let me know if you got it right bye!
Answer:
x = 5
Step-by-step explanation:
(since the equations are equal to eachother, add similiar factors)
4x - 3 = 2x + 7
+3. -2x
2x = 10
<em>Simplify</em>
x = 5
Answer:
if both sides are equal x's, then they are all real numbers. so 16x=16x, means it's all real numbers. 16x=16 is equal to x=1, dont mix this up.
The slope formula is y2-y1/x2-x1
x1 - 5
x2 - 4
y1 - 1
y2 - h
plug values into formula
(h-1)/(4-5)=8
(h-1)/-1=8
in order to get h by itself, multiply both sides by -1, and then add 1
h-1=-8
h=-7
