Answer:

(4x + 1)(2x - 5)

Step-by-step explanation:

To factor 8x² - 18x - 5

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 8 × - 5 = - 40, sum = - 18

The factors are + 2 and - 20

Use these factors to split the x- term, that is

8x² + 2x - 20x - 5 ( factor the first/second and third/fourth terms )

= 2x(4x + 1) - 5(4x + 1) ← factor out (4x + 1)

= (4x + 1)(2x - 5) ← in factored form

2) What is the inequality that this graph represents? -15 # 3 6 x​
kvasek [131]

Answer:  y < -\frac{1}{2}x+3

This is the same as writing y < (-1/2)x+3

==============================================================

Explanation:

The dashed boundary line goes through (0,3) and (4,1)

Apply the slope formula for those two points

m = (y2-y1)/(x2-x1)

m = (1-3)/(4-0)

m = -2/4

m = -1/2

The slope of the dashed line is -1/2. The y intercept is 3. So we go from y = mx+b to y = (-1/2)x+3 to represent the equation of the dashed line. This is the same as writing y = -\frac{1}{2}x+3

We shade below the dashed line to represent the inequality y < -\frac{1}{2}x+3. Points in the shaded region are solutions to the inequality. One example point is (0,0).

Note that we don't have "or equal to" as part of the inequality sign because we are not including points on the boundary. A solid line, rather than a dashed line, would include points on the boundary.

What is the solution to this system of equations?
Angelina_Jolie [31]
You can use elimination for this one so you can say

-2(3x+2y=10)
+2x+4y=4

So you have

-6x-4y=-20
+2x+4y=4

So you have

-4x=16

So x=-4

And then you can plug x into any one of the equations and solve for y

2(-4)+4y=4

-8+4y=4

Add 8 on both sides to get

4y=12

y=3

So in ordered pair form your answer is (-4,3)

Hope this helps!! Mark as brainliest!!!
