The question is asking us to find $f(x) - g(x) - h(x)$ . Since we know that $f(x) = 3x + 5$ , $g(x) = 4x^2 - 2$ , and $h(x) = x^2 - 3x + 1$ we can substitute these values into the original expression and simplify:

$f(x) - g(x) - h(x)$

$f(x) - g(x) - h(x) = (3x + 5) - (4x^2 - 2) - (x^2 - 3x + 1)$

$f(x) - g(x) - h(x) = \boxed{-5x^2 + 6x + 6}$

A store mixes Kentucky bluegrass worth $12 per pound and chewings fescue worth $15 per pound. The mixture is to sell for $13 per

quester [9]

The solution for the problem is as follows:

((12x + 15y)/228) = 13
x + y =228

x = kentucky bluegrass
<span>y = chewings fescue
</span>
By systems of linear equations, the answers would be:

x = 152
y = 76

Therefore, there should be 152 pounds of Kentucky bluegrass to be used and 76 pounds of chewings fescue.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

ADD is to MULTIPLY as SUBTRACT is to what

Rzqust [24]

Divide! If you add three and four, you get seven. Subtracting four from seven, you get three. If you multiply three and four, you get twelve. If you then divide by four, you get back to 3. I hope this helped!

A ship at sea, the Gladstone, spots two other ships, the Norman and the Voyager, and measures the angle between them to be 48°.

ratelena [41]

Answer:

=3501 yards.

Step-by-step explanation:

The three ships form a triangle. From the Voyager the angle between the Norman and the Gladstone=180-(55+48)=77°

Let the position of the Voyager be V that of Norman be N and that of the Gladstone be G

Then, the distance between Norman and voyager is g

g/sin G=v/ Sin V

4590/Sin 77=g/Sin 48

g=(4590 Sin 48)/Sin 77

=3500.8 yards

The distance between the Norman and the voyager= 3501 yards.

Brandon is shopping at Old Navy during a sale. All shorts are $16 each and all t-shirts are $10 each.He has $100 to spend and wo

DaniilM [7]

Let
x = the number of shorts bought
y = the number of t-shirts bought

A pair of shorts costs $16 and a t-shirt costs $10. Brandom has $100 to spend.
Therefore
16x + 10y ≤ 100
This may be written as
y ≤ - 1.6x + 10 (1)

Brandon wants at least 2 pairs of shorts. Therefore
x ≥ 2 (2)

Graph the equations y = -1.6x + 10 and x = 2.
The shaded region satisfies both inequalities.

Answer:
Two possible solutions are
(a) 3 pairs of shorts and 4 t-shirts,
(b) 4 pairs of shorts and 2 t-shirts.
