What is the simplified expression
Nady [450]

Answer:

7y - 4x

Step-by-step explanation:

Given

- 3(2x - y) + 2y + 2(x + y) ← distribute both parenthesis

= - 6x + 3y + 2y + 2x + 2y ← collect like terms

= - 4x + 7y

= 7y - 4x

What are the solutions of the inequality (x-3)(x+5)<=0
GarryVolchara [31]

Assuming that the inequality you were going for was a ≤, set both polynomials less than or equal to 0.

x - 3 ≤ 0

x + 5 ≤ 0

For the first equation add 3 to both sides of the inequality. For the second, subtract 5 from both sides.

x ≤ 3

x ≤ - 5

These would be your solutions I guess, however, if you want to expand upon that, your actual answer is (- ∞, - 5] because if you were to plot these two inequalities on a number line, that is where the overlap would occur.

What's the slope of the line passing through the point help​
scoray [572]

Answer:

the slope is 3/4

Step-by-step explanation:

The formula for slope is

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

The two points are given as (-1, 1) or (x1, y1), and (3, 4) or (x2, y2)

Plug those value into the formula and simplify

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

    m = 3/(3 + 1)

        m = 3/4

Election day is less than a month away, and political analysts are focused on the races for two statewide political offices. Acc
ExtremeBDS [4]

Answer:

0.1961

Step-by-step explanation:

Since these two probabilities are independent of each other, we can simply multiply them.

The probability that a voter will support the Democratic candidate for governor is 0.53.

The probability that a voter will support the Democratic candidate for attorney general is 0.37.

This makes the probability that a voter supports both Democratic candidates 0.53(0.37) = 0.1961.
