Important: If you're discussing squares, please express "the square of x" as x^2 (not as x2).
Please note that your y=x^2+3 is NOT a line. I will assume (probably incorrectly!) that you meant y=2x+3. The slope of this line is 2, so the slope of any line perpendicular to y=2x+3 is -1/2.
Now use the point-slope equation of a straight line:
y-8 = (-1/2)(x-1) (answer)
Answer:
7/25
Step-by-step explanation:
The fraction is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 4. 4 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 28 and 100.
Jane's friend is wrong, the original price would be $200
finding the product of 2 numbers means that you have to multiply those numbers

when multiplying fractions , numerators are multiplied by numerators and denominators by denominators

therefore product of 3/8 and 16 is 6
next we have to find 2/3 of 6
'of' operator means multiplication

answer is 4
28 cans of soda into 2 groups in which the ratio is 3:4
3 x 4 = 12
4 x 4 = 16
12 + 16 = 28
you will put 12 cans in one group and 16 cans in another group
hope this helps
