stich3 [128]3 years ago
8 0

Answer:

x= 11, -15

Step-by-step explanation:

(4x + 5) + x^2 +1 0) = 180

x^2 + 4x + 15 = 180

x^2 + 4x + 15 - 180 = 0

x^2 + 4x - 165 = 0

x = 11, -15

To eliminate the y-terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before ad
Kryger [21]

Answer:

The first equation should be multiplied by 9 and the second equation by −4

Step-by-step explanation:

Given the simultaneous equation

First Equation: 5x − 4y = 28

Second equation: 3x - 9y = 30

In order to eliminate y, we must make the coefficient of x in both expression to be equal.

To do that the first equation should be multiplied by 9 (negative value of the coefficient of y in equation 2)and the second equation by -4( (coefficient of y in equation 1)

Which of the following number lines depicts the solution to 4(x+1) &gt; 16 + 7x?
Nataly [62]

9514 1404 393

Answer:

  b) x < -4

Step-by-step explanation:

Eliminate parentheses and you have ...

  4x +4 > 16 +7x

  -12 > 3x . . . . . . . . subtract 4x+16

  -4 > x . . . . . . . . divide by 3

The number line will have an <em>open circle</em> at -4 and be shaded to the <em>left</em>. The pictures are a bit fuzzy, but we think choice B has that description.
