Hours He will work in this Week=20 hours.
Number of Hours he will Teach=x
Number of Hours He will Eat icecream=y
We know
x+y=20
x=20-y (Equation 1)
Teaching French=$12
Eating Icecream=$8
Let He Total Money he Earn from Teaching.
=12×Number of Hours he work
=$12x
Eating Icecream=$8
Total money spent=$8y
But Total Money=$190
MEANS
$12x+$8y=$190
12(20-y)+8y=190
240-12y+8y=190
-4y=190-240
-4y=-50
y=50/4
y=12.5
We know x+y=20
x+12.5=20
x=20-12.5
x=7.5 hours
MEANS He have to teach At least =7.5 hours.To make $190

Answer:
6 teaspoons
Step-by-step explanation:
2 teaspoons = 1/3 tsp of salt
6 teaspoons = 1 tsp of salt
This was done by multiplying 2 by 3 since 3 thirds (3/3) make one whole.
So if 2 teaspoons are used for 1/3 teaspoon of salt, 4 teaspoons would be used for 2/3 teaspoon of salt and 6 teaspoons would be used for 1 teaspoon of salt.
So the equation of the red graph is already given to us:
. I assume you meant the blue graph?
We can use the vertex form:
, where
is the vertex. (We can ignore
because
is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).
The vertex for
is at
on the coordinate plane. (4 left, 2 down)
Plug into the vertex form:

The double negative becomes a positive, and then you're done:
