Answer:
90
Step-by-step explanation:
120 - (120/4)
120 - 30 = 90
Answer:
(c)
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0
Then the product of the roots =
(k - 2)x² - 6x + 12 = 0 ← is in standard form
with a = k - 2 and c = 12 , thus
= 3 ( multiply both sides by (k - 1) )
12 = 3(k - 2) = 3k - 6 ( add 6 to both sides )
18 = 3k ( divide both sides by 3 )
6 = k → (c)
we are given
Since, we have to solve this inequality
so, we will isolate x on anyone side
step-1:
Multiply both sides by 3/2
step-2:
Distribute negative sign
step-3:
Subtract both sides by 1/2
step-4:
Subtract both sides by (3/10)x
step-5:
Multiply by sides by -10/23
now, we can simplify it
now, we can write in interval notation as

That point slope equation given does not pass through those points, the point slope equation y + 7 = -0.4(x - 10) does, though. The standard form of that would be
2x + 5y = -15
You can get that by distributing the -0.4 out
y + 7 = -0.4x + 4
You can then add 0.4x to both sides, and subtract 7 from both sides to get
0.4x + y = -3
Now some teachers may accept this, but in correct standard form the coefficient of x is a whole number, so you have to multiply both sides by 5 to get rid of the decimal, and you get
