Answer:
<h2>The slope m = -2</h2>
Step-by-step explanation:
The slope-intercept form of the equation of line:
We have
Therefore we have the slope = -2.
Answer:
The investment firm's total profit is $4,000
Step-by-step explanation:
The Profit from Company A = 11% * $8,000
= 11 * $8,000/100
= $880
The Profit from Company B = 13% * $24,000
= 13 * $24,000/100
= $3,120
The total profit = $880 + $3120
= $4,000
Thus, the investment firm's total profit is $4,000
Start by moving all terms to left side of equation 4x^2 - 19x - 30 = 0
Multiply 4 x -30 = -120
Now find two factors of 120 that subtract to give 19... 1 x 120, 2 x 60, 3 x 40, 4 x 30, 5 x 24 ✅
[if it had been +120 we would add the factors looking for 19 which in this case don’t exist]
To get -19 we will need 5 + -24
24 is a multiple of 4 so we can use 4 x -6 and 1 x 5
Giving a factored equation of (4x + 5)(x - 6) = 0 [you should check this by expanding to remove the brackets]
One of the brackets must = zero so the solutions are x = -5/4 or x = 6
Some people look at factors of 4 and -30 and then pair then up to find a sum of -19 but this can take longer to finish.
Answer:
(2) Real and equal (i.e., repeated roots), if D = 0.
Step-by-step explanation:
.In a quadratic equation ax2 + bx + c = 0, if discriminant is D= b2 - 4ac, then roots of the quadratic equation are
Real and equal (i.e., repeated roots), if D = 0.
If the D > b² - 4ac then it's real and distinct.
