Answer:
3 7/12
Step-by-step explanation:
You solve for y so then u subtract the 7x from 30 to get 30-7x equals -10 since the -10 has a variable it means u divide by -10 to the subtracting equation to get-3+7/10
As a tip, remember that whenever a problem says "of," multiply. So if you want to find brown hair and long hair, multiply, 4/5*3/4.
4/5*3/4=12/20=3/5
Part A: 3/5 of the girls in the fifth grade class have long brown hair.
If they have long brown hair and green eyes, multiply 3/5*1/3. Since it is all three, get the answer from above and multiply it by 1/3.
3/5*1/3=3/15=1/5
Part B: 1/4 of the girls in the fifth grade class have long brown hair and green eyes.

Answer:
The line does not intersect the curve
Step-by-step explanation:
Assuming that we are looking for the points of intersection of
and
We make y the subject in the second equation to get:
When we substitute into the first equation:
Let us expand to get:
We obtain the standard form
Divide through by 5
The discriminant is
Hence the quadratic equation has no real roots.
This means the line and point has no point of intersection.
