Answer:

Infinite solutions

Step-by-step explanation:

it does not matter what you put for x because if you put a 2 in x it will still be in the same line if x was 103984098540968450

The solution can be found where two lines intersect. The lines in the image do not intersect at an exact point, so we will need to estimate.
The x value is either 1 or -1 from your choices. You can see it is closer to -1 on the horizontal (x axis).
The y value is either 0 or -1 from your choices. You can see it is closer to 0 on the vertical (y axis).
The answer to your set of lines is approximately (-1,0).

What are the solutions of 3x2 + 14x + 16 = 0?

nevsk [136]

Good evening ,

Answer:

x = StartFraction negative 8 Over 3 EndFraction, –2

Step-by-step explanation:

3x² + 14x + 16 = 0

3x² + 6x + 8x + 16 = 0

(3x² + 6x) + (8x + 16) = 0

3x(x+2) + 8(x+2) = 0

(x+2)(3x+8) = 0

x = -2 , x = -8/3.

-2,-7,-12 ,.... is an arithmetic sequence Find the sum of its first 20 terms ?

nlexa [21]

Given sequence:

-2,-7,-12 ,..

Unknown;

Find the sum of the first 20 terms = ?

Solution:

The sequence is -2,-7,-12 ,..

To find he sum of n-terms of a sequence, we use the expression below;

Sₙ = $\frac{n}{2} (2a + (n-1)d)$

where n is the number of terms = 20

a is the first term = -2

d is the common difference= -7 - (-)2 = -5

Now input the parameters and solve;

Sₙ = $\frac{20}{2} (2(-2) + (20 - 1) x -5)$

Sₙ = 10(-4 + -5(19)) = 10(-99) = -990

The sum of the first 20 terms of the sequence is -990
