Answer:
-5+(√x-3) and -(√x-3)-5
Step-by-step explanation:
change f(x) to 'y' and then interchange x and y; then solve for y
y = x² + 10x + 28
x = y² + 10y + 28
you can use the Quadratic Formula to evaluate y² + 10y + 28 and will get:
-5+(√x-3) and -(√x-3)-5
To determine how many more cars will travel on the bridge during peak time in two years, you will find what 3.4% of 975 vehicles is for the first year.
Add this number to the 975, and then multiply 0.034 times the new number of vehicles.
Here is the math:
0.034 x 975 = 33.15
This round to 33 more vehicles.
975 + 33 = 1008
0.034 x 1008 = 34.272
There will be about 33 + 34 (67) more vehicles on the bridge in two years.
Answer:
<h2>
B. 4 StartRoot 2 EndRoot i
</h2>
Step-by-step explanation:
Given the surd function √-2 and √-18, we are to fund the sum of both values.
Taking the sum:
= √-2 + √-18
= (√2 * √-1)+ (√18 *√-1)
from complex numbers, √-1) = i
The expression becomes
= √2 i+ √18 i
= √2 i+ √9*2 i
= √2 i+ 3√2 i
= 4 √2 i
= √-2 + √-18 = 4 √2 i
The result is 4 StartRoot 2 EndRoot i
The answer is x=-4 because you subject 5 on both sides and than divide -2 both sides and it leaves you with x=-4.
Answer:
substitute the given values for m, n, and p into each problem and solve. Make sure you don't ignore minuses and negatives. Separate with parentheses to make sure you don't get confused.
