Answer:

5.50x + 2y ≤ 18

Step-by-step explanation:

Romona has a total of $18 and she has to spend it on dog food.

Dry god food cost $5.50 per bag and wet dog food cost $2.00 per can.

We have to write an inequality to show the above condition.

Let the number of dry and wet dog food she buys be x and y.

The total cost of dog food must be less than $18.

Then,

5.50x + 2y ≤ 18

This is the required linear inequality.

Find the missing coefficients <br><br><br>y=ax^2-10x+c <br>vertex :(-5,20)
Citrus2011 [14]
Remember, for y=ax^2+bx+c the x value of the vertex is \frac{-b}{2a}

so
given
x value of vertex is -5
and
y=ax^2-10x+c
\frac{-b}{2a}=\frac{-(-10)}{2a}=\frac{10}{2a}=
\frac{5}{a}=-5
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1


y=-1x^2-10x+c
comlete the square
remember if we do
y=a(x-h)^2+k (h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand

y=-1(x-(-5))^2+20
y=-1(x+5)^2+20
y=-1(x^2+10x+25)+20
y=-1x^2-10x-25+20
y=-1x^2-10x-5

a=-1
c=-5

24% of 603 = 144.72
