elena-14-01-66 [18.8K]

Answer:

x > -1 or x < -1

Step-by-step explanation:

For the first equation, 5x-29 > -3

Step 1: Move the constant to the right and change its sign

5x-29 > -34

5x > -34+29

Step 2: Calculate the sum

5x > -34+29

5x > -5

Step 3: Divide both sides of the inequality by <em>5</em>

5x > -5

x > -1

<em><u>Answer</u></em><em><u>:</u></em> -1

For the second equation, 2x+31 < 29

Step 1: Move constant to the right and change its sign

2x+31 < 29

2x < 29-31

Step 2: Calculate the difference

2x < 29-31

2x < -2

Step 3: Divide both sides of the inequality by 2

2x < -2

x < -1

<em><u>Answer</u></em><em><u>:</u></em> x < -1

What is x+4y=6 and y=-x+3 substituted
zavuch27 [327]
If x + 4y = 6 and you subst. -x+3 for y, you get    x + 4(-x+3) = 6.

Then x - 4x + 12 = 6, or -3x = -6, or x = 2.  Since y = -x+3, here y = -(2)+3 = 1.

Thus, the solution to this system of linear equations is (2,1).

What is the value of the discriminant of the quadratic equation −1 = 5x2 −2x, and what does its value mean about the number of r
joja [24]
The correct answer for this question is "The discriminant is equal to −16, which means the equation has no real number solutions."

<span> −1 = 5x2 −2x
</span><span>5x2 −2x + 1 = 0
</span>
To get the discriminant value, use this formula
= b^2 - 4ac
= (-2)^2 - 4(5)(1)
= 4 - 20
= -16
