Answer:

7x² + 5x

Step-by-step explanation:

Given

(9x² + 8x) - (2x² + 3x) ← distribute parenthesis, second by - 1

= 9x² + 8x - 2x² - 3x ← collect like terms

= (9x² - 2x² ) + (8x - 3x)

= 7x² + 5x

Distribute the negative sign:

$(9x^2+8x)-(2x^2+3x)=9x^2+8x-2x^2-3x$

Gather like terms:

$9x^2+8x-2x^2-3x = (9x^2-2x^2) + (8x-3x) = 7x^2+5x$

Answer:

x≥1 or x≤−3

Step-by-step explanation:

x+1≥2 possibility 1

x+1−1≥2−1 Subtract 1 from both sides

x≥1

x+1≤−2 Possibility 2

x+1−1≤−2−1 Subtract 1 from both sides

x≤−3

You are asked to choose a vowel (a, e, i, o, u) from a list, and then to choose either the number 6 or 7. How many possible outc

faltersainse [42]

Answer:

10 possible outcomes

S = {a6, a7, e6, e7, i6, i7, o6, o7, u6, u7}

Step-by-step explanation:

As there are 5 vowels and 2 numbers that have to be chosen, the total outcomes are

= 5x2 = 10

Each vowel can be chosen with 6 or with 7

Let S be the sample space

a vowel will be chosen first then there is possibility that either the number chosen with it is either 6 or 7 so each vowel will have two possible outcomes with the number

S = {a6, a7, e6, e7, i6, i7, o6, o7, u6, u7} ..

Which represents the solution(s) of the graphed system of equations, y = x2 – 2x and y = –2x – 1? (1, –1) (0, 0) and (0, –1) (0,

olganol [36]

ANSWER

No solution

EXPLANATION

The first equation is

$y = {x}^{2} - 2x$

and the second equation is

$y = - 2x - 1$

We equate the two equations to obtain;

${x}^{2} - 2x = - 2x - 1$

This implies that

${x}^{2} = - 2x + 2x - 1$

${x}^{2} = - 1$

There is no real number whose square is -1.

Therefore, the equation has no solution.
