Answer:
Yes
Step-by-step explanation:
14 and 5 have a sum of 19 and a difference of 9
19/25 * 100 = 1900/25 = 76 ....numbers greater then 15
7/50 * 100 = 700/50 = 14....numbers less then 15
100 - (76 + 14) = 100 - 90 = 10 <== numbers equal to 15
Answer:
y = -3x + 7
Step-by-step explanation:
Using the equation of line
y = mx + C
y - y_1 = m(x - x_1)
First find the slope
With eqn y = 1/3x - 3
Note, if two lines are perpendicular, their slope will be negative reciprocal
slope = m = -3/1
Using y - y_1 = m(x - x_1)
With point ( 3, -2)
x_1 = 3
y_1 = -2
y - (-2) = -3/1(x - 3)
y + 2 = -3/1(x -3)
Open bracket
y + 2 = -3(x - 3)/1
y + 2 = (-3x +9)/1
y = (-3x + 9 )/1 - 2
LCM is 1
y = -3x + 9 - 2
y = -3x + 7
The equation of the line is
y = -3x + 7
The answer is 8! or 40,320.
8*7*6*5*4*3*2*1=40,320
Answer:
The first step in solving the equation is "set each binomial factor equal to zero" ⇒ 3
Step-by-step explanation:
To solve a quadratic equation y = ax² + bx + c
- Put y = 0
- Factorize it into two binomial factors (x ± m)(x ± n)
- Equate each binomial factor by 0 to find the values of x
- The values of x are the solution of the equation
∵ The equation is (x + 2)(x - 3) = 0
∵ The equation equated by 0
∵ It is factored into 2 binomial factors (x + 2) and (x - 3)
- The next step is equated each factor by 0 to find the values of x
∴ The 1st step in solving (x + 2)(x - 3) = 0 is set x + 2 = 0 and
x - 3 = 0
The first step in solving the equation is "set each binomial factor equal to zero"
