Answer:
m<A = 30degrees
m<B = 70degrees
Step-by-step explanation:
Find the diagram attached
From the diagram;
m<A + 150 = 180
m<A = 180 - 150
m<A = 30degrees
Also since the sum of angles in a triangle is 180degrees, hence;
m<B+m<A + 80 = 180
m<B+30+80 = 180
m<B+110 = 180
m<B = 180 - 110
m<B = 70degrees
Answer:
It is the third option. (the one which has a black point at X=1, Y=1)
Step-by-step explanation:
For simplicity what you should do is, you should satisfy the second condition that is, y=0 if x=1.
Here only the third option is satisfying this condition.
Whenever there is is a white circle or a white point it means that the point does not satisfy the condition and the the function is not defined at that point. And the black point means that the circle is defined at that point and satisfies the condition.
Henceforth, the correct answer is the third option.
Answer:
X = 6
Step-by-step explanation:
4x - 2 = 3x + 4 /subtract -3x
x - 2 = 4 /add 2
x = 6
Answer:
slope is 5, y intercept is -7
Step-by-step explanation:
In the form y=mx+c, m is the slope and c is the y-intercept.
Rearrange the formula to fit this form:
5x-y=7
-y=7-5x
y=5x-7
∴m(slope)=5
∴c(y-intercept)=-7
If m∠1 = 60°, then m∠2 = 30°
because they are complementary because perpendicular lines form 90° (right) angles
90 - 60 = 30
