40% of 60 is 24
To convert from percent to decimal, divide the percent without the percent symbol by 100.
so, 40% = 40/100 = 0.4
40% 60 is just 0.4*60 = 24
2x2-5x-3=0
Two solutions were found :
x = -1/2 = -0.500
x = 3
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(2x2 - 5x) - 3 = 0
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 2x2-5x-3
The first term is, 2x2 its coefficient is 2 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 2 • -3 = -6
Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is -5 .
Answer:
Step-by-step explanation:
The leftmost line segment has a slope of -2 and (-1,-1) is a point on the line.
Equation: y = -2x-3
middle line segment has a slope of 0 and y-intercept of -2.
Equation: y = -2
The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.
y = 1.5(x-5) = 1.5x-7.5
The summation of negative 5 n minus 1, from n equals 3 to 12 can be
expressed as
n = 3/12
substitute the value of n to the equatio
-5n – 1
-5( 3/12 ) -1
-9/4
