Answer:
y=-2x + 8 which is the required equation
Which is option C
Step-by-step explanation:
Given:
Slope = m = -2
Given points are ( -2,12)
Which is
x = -2 and y =12
TO find:
Equation of line passing through these points = ?
Solution:
The point slope form of a line is
y = mx + c
Here we don't know the value of c
To find it
Putting y = 12 , x= -2 and y = -2 in the given equation
y = mx + c
Putting values it becomes
12 = (-2)*(-2) + c
12 = 4 + c
Subtracting 4 from both sides
12-4 = 4 -4 + c
8 = c
Now we have
m = -2 and c= 8
So equation of a line is given by
y = mx + c
Putting value of m and c
y = -2*x + 8
y=-2x + 8 which is the required equation
Answer:
A= 74.47
Step-by-step explanation:
you add the 24.8 to the right side to get a by itself
Answer:
75% of the votes were in favor.
Step-by-step explanation:
To find the percent(rate), we use the formula r=p/b
The question is "What percent(rate) of 56 is 42?"
So fill in the formula and it will show as r=42/56, which is the rate will be equal to 42 divided by 56.
Perform the calculations and the result will show 0.75
Convert the decimal to a percent by moving the decimal point two places to the right and you will have 75% as your answer.
This should be 2x^2 + 7x - 4
Answer:
m<ALO=35°
Step-by-step explanation:
we know that
The right triangle AOL is congruent with the right triangle BOL
because
OA=OB=radius of the circle
OL is a common side
LA=LB ---> by applying the Pythagoras theorem
therefore
m<AOL=m<AOB/2
m<AOL=110°/2
m<AOL=55°
Remember that
m<AOL+m<ALO=90° ------> by complementary angles
m<ALO=90°-55°=35°
