Factor the expression y2+6y-16

Mathematics
2 answers:
Arisa [49]3 years ago
8 0

Step 1 ) Break up the expression.

\displaystyle\ y^{2} + 6y -16

\displaystyle\ (y^{2} -2y) + (8y -16)

Step 2 ) Factor y from y^{2} - 2y.

\displaystyle\ (y^{2} -2y) + (8y -16)

\displaystyle\ y ( y - 2 )

Step 3 ) Factor 8 from 8y - 16

\displaystyle\ (y^{2} -2y) + (8y -16)

\displaystyle\ 8 ( y - 2)

Step 4 ) Place new factors in group.

\displaystyle\ y ( y - 2 )

\displaystyle\ 8 ( y - 2)

\displaystyle\ y(y-2)+8(y-2)

Step 5 ) Distribute.

\displaystyle\ y(y-2)+8(y-2)

\displaystyle\ (y-2) + 8(y-2)

\displaystyle\ (y-2) (y+8)

The expression factored is...

\framebox {=(y-2)(y+8)}

y^2+6y-16=y^2+8y-2y-16=y(y+8)-2(y+8)=(y+8)(y-2)

Bethany sells roses and petunias. The expression 3r+2.5p3r+2.5p3, r, plus, 2, point, 5, p gives the cost (in dollars) of rrr ros
Vaselesa [24]

Answer:

I think the equation is written as 3r + 2.5p, where r is the number of roses and p is the number of petunias. To find the total cost, substitute 777 to r and 888 to p. The total cost would then be:

Total Cost = 3r + 2.5p

Total Cost = 3(777) + 2.5(888)

Total Cost = 4551

The total cost would be $4,551.

Kryger [21]

Answer: Algebraically, linear functions are polynomial functions with a highest exponent of one, exponential functions have a variable in the exponent, and quadratic functions are polynomial functions with a highest exponent of two.

Step-by-step explanation: A linear equation is a type of equation in which the graph is straight and each term is a constant or a power of a constant. The formula is y=mx+b. Quadratic equations are similar to exponential equations by having a curve in the graph.
