To find if a shape is congruent, just see if they are the same size and shape. If they are, it's congruent. If not, they aren't.

Vanyuwa [196]

Absolute value is the distance from a value to zero. In this case, it'd be written as | -282 |. If x = | -282 |, then x = 282

A real estate sales agent receives a salary of $250 per week plus a commission of 2% of sales.Write an equation that gives the w

lisabon 2012 [21]

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Step-by-step explanation:

Given,

Weekly salary of real estate agent = $250

Commission rate = 2%

Let,

x be the sales per week.

y be the total weekly income.

Amount of commission = 2% of sales per week

Amount of commission = $\frac{2}{100}*x$

Amount of commission = 0.02x

Total weekly income = Amount of commission + Weekly salary

$y=0.02x+250$

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Answer:

x = 2y - 7

x + y = 47

substitute x

2y - 7 + y = 47

3y = 54

y = 18

x = 2x18 - 7

x = 29

What are the real zeros of the function g(x) = x3 + 2x2 − x − 2?

Nat2105 [25]

Upon a slight rearrangement this problem gets a lot simpler to see.

x^3-x+2x^2-2=0 now factor 1st and 2nd pair of terms...

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

(x+2)(x^2-1)=0 now the second factor is a "difference of square" of the form:

(a^2-b^2) which always factors to (a+b)(a-b), in this case:

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

So g(x) has three real zero when x={-2, -1, 1}

7x + 2y = 4

Vinil7 [7]

$7x + 2(x + 1) = 4 \\ 7x + 2x + 2 = 4 \\ 9x + 2 = 4 \\ 9x = 2 \\ x = \frac{2}{9} \\ \\ y = \frac{2}{9} + 1 = \frac{11}{9} \\ ( \frac{2}{9} \: \frac{11}{9} )$
