Answer:

Step-by-step explanation

Factoring: 2x3-5x2+7x-6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 7x-6

Group 2: 2x3-5x2

so its c

Pull out from each group separately :

Group 1: (7x-6) • (1)

Group 2: (2x-5) • (x2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Identify the domain of the function shown in the graph.

Alexus [3.1K]

Answer:

A, all real numbers

Step-by-step explanation:

The domain is the x value and the x value is the domain.

So when you take a look at the x values, it keeps going on and on

So when x values or y values keep going on forever we call that all real numbers

Answer:

The answer is 80°

Step-by-step explanation:

pls give brainliest!

all angles = 360°

100+100+80=280°

360°-280°=80°

Kyle borrows $4000 at 7% interest rate for 5 year. What is the total that Kyle will back?

pentagon [3]

Step-by-step explanation:

To find interest, multiply the principal (4000) by the rate (7%) and time in years (5).

I = Prt

I = (4000 * 5) * 7/100

I = 20000/1 * 7/100

Use cross cancellation (100 and 20000 have a GCF of 100)

I = 200/1 * 7/1

I = 200 * 7

I = $1,400

Kyle gets $1,400 in interest in this scenario.

The axis of symmetry for the function f(x) = −x2 − 10x + 16 is x = −5. What are the coordinates of the vertex of the graph?

OLga [1]

Answer:

The coordinates of the vertex are (-5, 41)

Step-by-step explanation:

For a quadratic function of the form

$f(x) = ax ^ 2 + bx + c$

Where a, b and c are constants and represent the coefficients of the function, then the symmetry of the parabola always passes through its vertex.

In this case we have the following parabola

$f (x) = -x2 - 10x + 16$

And we know that its axis of symmetry is the line $x = -5$

Then we know that this axis of symmetry passes through the vertex of the parabola.

Therefore, the x coordinate of the vertex is -5.

To find the coordinate in y of the vertex, we substitute x = -5 in the function.

$f (-5) = -(- 5) ^ 2 -10 (-5) +16\\\\f (-5) = 41$

Finally, the vertices are in the point (-5, 41).
