Answer:
x = 7/5 or x = (-7)/5
Step-by-step explanation:
Solve for x over the real numbers:
49 - 25 x^2 = 0
Multiply both sides by -1:
25 x^2 - 49 = 0
x = (0 ± sqrt(0^2 - 4×25 (-49)))/(2×25) = ( ± sqrt(4900))/50:
x = sqrt(4900)/50 or x = (-sqrt(4900))/50
sqrt(4900) = sqrt(4×25×49) = sqrt(2^2×5^2×7^2) = 2×5×7 = 70:
x = 70/50 or x = (-70)/50
70/50 = 7/5:
x = 7/5 or x = (-70)/50
(-70)/50 = -7/5:
Answer:x = 7/5 or x = (-7)/5
X=10 and y=20 is the answer
Answer:
1. Proportional
2. Not proportional
3. Not proportional
Step-by-step explanation:
Let's see what percentage of the $8.80 order is the $1.32 tip.
To find what percent a p[art is of a whole, divide the part by the whole and multiply by 100%.
$1.32/$8.80 * 100% = 15%
Mike's tip was $15% of the total.
1. $2.22 tip on $14.80 order
15% of $14.80 = 0.15 * $14.80 = $2.22
Tip is proportional
2. $1.86 tip on $10.50 order
15% of $10.50 = 0.15 * $10.50 = $1.58
Tip is nor proportional
3. Same as option 2 above.
