Answer:
Equation of a line that passes through the points (6, 8) and ( -2, 4) in
slope intercept form is
Step-by-step explanation:
General Equation of straight line is
---------- (1)
Here
Substituting values in (1)
Simplifying it further
Answer:
From the General Equation of a straight line
Y=Mx + c
where M = Slope of the line
c= Intercept on Y axis
y=-4.2x-80
Comparing with the Eqn of a straight line
Slope = -4.2
From the Options the answers are in Fractions
You can easily convert this figure to fraction by Moving the decimal to the back once and then divide by 10
Then we have -42/10
Reducing Further
you have = -21/5.
Option D✅
Since the quadratic formula of ax^2+bx+c is
x=(-b+-(plus OR minus) sqrt (b^2-4ac))/2a, we can get that a is 1 (since 1*x^2 is x^2), b is 4, and c is -16, so x=(-4+-sqrt((-4)^2-4*1*(-16)))/2*1
= (-4+-sqrt(16-(-64)))/2=(-4+-sqrt(80))/2 which is either (-4+sqrt(80))/2 or
(-4-sqrt(80))/2. Since 80 is divisible by 4 (aka 2 squared), we can write sqrt(80) as 2*sqrt(20) as 4 goes into 80 20 times, getting (-4+2sqrt(20))/2 or
(4-2sqrt(20))/2, and crossing out the 2's we get (-2+sqrt(20)) or (-2-sqrt(20))
Answer:
x = 29, C
Explanation: We are given that total angle is 90°, or a right angle. This means that the two complementary angles must equal 90° together.
Create the equation:
2x - 4 + x + 7 = 90
Solve algebraically:
3x + 3 = 90
3x + 3 - 3 = 90 - 3
3x = 87
3x / 3 = 87 / 3
x = 29 or C
The unit rate that the turtle is crawling is: (1/23)/(5/6) = (1/23)*(6/5) = 6/115 miles/hour.
