Answer:
-10x + (8x - 32) + 7
-10x + 8(x - 4) + 7
-20x + 8(2x-8) + 14
Step-by-step explanation:
-10x + (8x - 32) + 7
Multiplied the 4 outside the parentheses
-10x + 8(x - 4) + 7
Took 2 out of the parenthesis
-20x + 8(2x-8) + 14
Multiplied the entire thing by 2
First turns those into fractions, now you should have 4/5 and 1/5.
Now to generate a chance the 2 events will happen in a row (Like rain and a postponed game) you need to multiply the 2 fractions together so it should come out with 4/25 or 16%
Answer:
k=5
Step-by-step explanation:
for every one unit on the x, the y goes up five. So, the ratio is 5:1 or five.
Answer: x = -.63, -2.37
Step-by-step explanation:
x=−32±3–√2
x=−0.633975
x=−2.36603
Find the Solution for
2x2+6x+3=0
using the Quadratic Formula where
a = 2, b = 6, and c = 3
x=−b±b2−4ac/√2a
x=−6±62−4(2)(3)/√2(2)
x=−6±36−24/√4
x=−6±12−−√4
The discriminant b2−4ac>0
so, there are two real roots.
Simplify the Radical:
x=−6±23–√4
x=−64±23–√4
Simplify fractions and/or signs:
x=−32±3–√2
which becomes
x=−0.633975
x=−2.36603
Answer:
The answer is B. (7,5)
Step-by-step explanation:
1. Simplify the equation
y-5=6(x-7)
y=6(x-7)+5
y=6x-42+5
y=6x-37
2. Plot the line
3. Plot the points
