Y = 1x + 2 is the answer therefore the missing number is 1,2
We have an equation: ?/45= 24/100
Cross multiply:
100*? = 24*45
⇒ ?= 24*45/100= 10.8
24% out of 45 is 10.8~
Answer:
52°, 90°
Step-by-step explanation:
The two acute angles in a right triangle are complementary, because the third angle is 90°. For acute angles A and B, we must have ...
90° + A + B = 180°
A + B = 90° . . . . . subtract 90°; definition of complementary angles
B = 90° - A
For angle A = 38°, this tells us ...
B = 90° -38° = 52°
The other two angles in the triangle are 90° and 52°.
If either a or b or both are 0, we have |ab|= 0 and |a|*|b|=0
For any real number a and b non equal to 0, one of the 3 following cases are true:
i) both a and b are positive:
then |ab|=ab, |a|=a, |b|=b
ab=a*b
|ab|=|a|*|b|
ii) both a and b are negative:
then |a|=-a, |b|=-b
|ab|=ab, for example if a=-3, b=-7: |(-3)(-7)|=|21|=21=(-3)(-7)=a*b
so
ab=(-a)*(-b)
|ab|=|a|*|b|
iii) one of them is positive and the other negative.
In our case let a be positive, b negative:
|a|=a, |b|=-b,
and |ab|=-ab, for example if a=3, b=-4; |3*(-4)|=|-12|=12=3*(4)=a*(-b)
thus:
-ab= a*(-b)
|ab|= |a||b|.
In each possible case of the signs of a and b we get: |ab|= |a||b|.
Calculate the slope using the slope formula
m = (y2-y1)/(x2-x1)
m = (5-(-1))/(-6-(-8))
m = (5+1)/(-6+8)
m = 6/2
m = 3
The slope is 3
The point your teacher uses is (-6,5) because of the y-5. Note how it's in the form y-y1 where y1 = 5
So (x1,y1) = (-6,5)
Point Slope Form
y-y1 = m(x-x1)
y-5 = 3(x-(-6))
y-5 = 3(x+6)
The equation in point slope form is
y-5 = 3(x+6)
So you'll type 3(x+6) into the box
