Answer:

x = 1/2 or x = -4

Step-by-step explanation:

Since the product equals zero, use the zero product rule.

(2x - 1)(x + 4) = 0

2x - 1 = 0 or x + 4 = 0

2x = 1 or x = -4

x = 1/2 or x = -4

Answer: you have 2 solutions for that equation, 1/2 and -4

Step-by-step explanation:

(2x-1)(x+4)=0

2x^2+8x-x-4=2x^2+7x-4

use the formula for quadratic equations

x₁ and x₂ =-(7 (+-) $\sqrt49+32$ )/4=

we have x1= 1/2 and x 2=4

M + (-9.5) = -7.8

First, simplify your brackets. / Your problem should look like: $m + -9.5 = -7.8$
Second, change addition to subtraction. / Your problem should look like: $m - 9.5 = -7.8$
Third, add 9.5 to both sides. / Your problem should look like: $m = -7.8 + 9.5$
Fourth, simplify. / Your problem should look like: $m = 1.7$

Determine whether the relation shown is a function. Explain how you know.

lutik1710 [3]

Answer:

It is not a function

Step-by-step explanation:

The plot shows (1, 1) and (1, 3) are both defined by the relation. It does not pass the "vertical line test", which requires the relation be single-valued everywhere.
