Answer:

Option C. -3x^2-13x-5

Step-by-step explanation:

we know that

To find how much greater is the area of room A than the area of room B. subtract the area of room B from the area of room A

so

(5x^{2}-7x-6)-(8x^{2}+6x-1)\\ \\= (5x^{2}-7x-6)-8x^{2}-6x+1\\ \\=(5x^{2}-8x^{2})+(-7x-6x)+(-6+1)\\ \\=-3x^{2} -13x-5

Lourdes has 3times as much money than ella. Together they have $32 . How much money does Lourdes have ?
Mariana [72]

Answer:

Lourdes has $24.

Step-by-step explanation:

The appropriate equation would be L + (L/3) = $32, or 3L + L = $96.

Solving for L:  4L = $96, and L = $24.  This is 3x what Ella has, so Ella has $8.

Check:  Do $8 and $24 add up to $32?  YES

Sterling silver is an alloy of silver that is 92.5% pure silver. If x grams
nlexa [21]

Answer:

D. 0.925x + 0.88y = 0.91(x + y)  

Step-by-step explanation:

The important point to remember is that the total mass of pure silver is the same on each side of the equation.

0.925x = mass of pure silver in first alloy

0.88  y = mass of pure silver in second alloy

The final alloy has a mass of (x + y) g and is 91 % pure silver, so

0.925x + 0.88y = 0.91(x + y)

Evaluate the following expressions giving the functions g(x)= -4x+3 <br> g(10) is the expression
Artemon [7]

Answer:

g(10) = -37

Step-by-step explanation:

g(x)= -4x+3

g(1) means evaluate when x=10

g(10) = -4*10 +3

g(10) = -4*10 +3

g(10) = -40+3

g(10) = -37

Bc has endpoints b(5 ,9) and c(-4, -3). Find the coordinates of the midpoint of bc
Alex73 [517]
We can find the midpoint of any line segment using the midpoint formula: M=(x1+x2/2,y1+y2/2). Essentially, the midpoint formula finds the average of two points. If we use B and the first point and C as the second, when we plug in our values we would have M=(5-4/2,9-5/2). This can be simplified to M=(1/2,4/2) or M=(1/2,2) which is the final answer.
