Answer:
y = (-4/5)x - 7/5
Step-by-step explanation:
The general equation of the line is slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept. You have been given the value of the slope (m = -4/5). To find the y-intercept, use the slope and values from the Point (2,-3) to isolate "b".
y = mx + b <----- Slope-intercept form
y = (-4/5)x + b <------ Plug -4/5 in "m"
-3 = (-4/5)(2) + b <----- Plug in "x" and "y" values from Point
-3 = -8/5 + b <------ Multiply -4/5 and 2
-15/5 = -8/5 + b <----- Assign common denominator
-7/5 = b <----- Add 8/5 to both sides
Now that you have the slope and y-intercept, you can construct the equation.
y = (-4/5)x - 7/5
The smallest perimeter is 72.44 inches. The longest side of an acute triangle measures 30 inches. The two remaining sides are congruent, but their length is unknown. As much as possible, the sum of the length of the two remaining side must be greater than the other side. Given the side is 30, then the sum of the two remaining sides should be greater than 30 inches.
The answer is: 36 in total
To find surface area, we can use the equation:
SA=2lw+2wh+2lh, where:
l=10 in
w=3 in
h=7 in
SA=(2)(10)(3)+(2)(3)(7)+(2)(10)(7)
SA=60+42+140
SA=242 in²
No because when you add any 2 sides the answer has to be bigger than the 3rd side
ex: 2+7=9
9 is too small, so the tips of the side that is 2ft would not touch the side that is 7ft
