What is the value of x in x+y=-10 and x-y=2

loris [4]

Answer:

x = -4

Step-by-step explanation:

x+y = -10 -------- (1)

x-y = 2 ------- (2)

from (1)

x+y = -10

y = -10-x -------- (3)

substitute (3) into (2)

x-y = 2

x-(-10-x) = 2

x+10+x = 2

2x = 2-10

2x = -8

x = -8/2

x = -4

Someone just answer this math question thingie lol. you’ll get 33 points G

Stels [109]

1) $(-2x+4)+(x-6)$ is simplified into $=-x-2$

2) $(uv-3)+(4uv+1)$ is simplified into $5uv-2\\$

3) $(11x-8)-(2x+3)$ is simplified into $-9x-11$

4) $(x^2-4)-(x-2)$ is simplified into $x^2-x-2$

5) $(12-3t-7t^2)+(1+3t-t^2)$ is simplified into $-8t^2+13$

Step-by-step explanation:

We need to solve the polynomials.

1) $(-2x+4)+(x-6)$

Solving:

$(-2x+4)+(x-6)\\=-2x+4+x-6\\Combining\,\,like\,\,terms:\\=-2x+x+4-6\\=-x-2$

So, $(-2x+4)+(x-6)$ is simplified into $=-x-2$

2) $(uv-3)+(4uv+1)$

Solving:

$(uv-3)+(4uv+1)$

Expanding:

$=uv-3+4uv+1\\Combining\,\,like\,\,terms:\\=uv+4uv-3+1\\=5uv-2\\$

So, $(uv-3)+(4uv+1)$ is simplified into $5uv-2\\$

3) $(11x-8)-(2x+3)$

Solving:

$(11x-8)-(2x+3)$

Expanding:

$=11x-8-2x-3\\Combining\,\,like\,\,terms:\,\,\\=11x-2x-8-3\\=-9x-11$

So, $(11x-8)-(2x+3)$ is simplified into $-9x-11$

4) $(x^2-4)-(x-2)$

Solving:

$(x^2-4)-(x-2)$

Expanding:

$=x^2-4-x+2\\Combining\,\,like\,\,terms:\\=x^2-x-4+2\\=x^2-x-2$

SO, $(x^2-4)-(x-2)$ is simplified into $x^2-x-2$

5) $(12-3t-7t^2)+(1+3t-t^2)$

Solving:

$(12-3t-7t^2)+(1+3t-t^2)$

Expanding:

$=12-3t-7t^2+1+3t-t^2\\Combining\,\,like\,\,terms:\\=12+1-3t+3t-7t^2-t^2\\=13+0t-8t^2\\=-8t^2+13$

So, $(12-3t-7t^2)+(1+3t-t^2)$ is simplified into $-8t^2+13$

Solve the equations. a. 4a^2 = 16 b. 5????^2 − 25 = 0 c. 8 − c^2 = 5

Vera_Pavlovna [14]

Answer:

$a=\pm 2$ , $x=\pm \sqrt{5}$ and $c=\pm \sqrt{3}$ .

Step-by-step explanation:

Consider the given equations are

a. $4a^2=16$

b. $5x^2-25=0$

c. $8-c^2=5$

(a)

$4a^2=16$

Divide both sides by 4.

$a^2=4$

Taking square root on both sides.

$a=\pm \sqrt{4}$

$a=\pm 2$

(b)

$5x^2-25=0$

Add 25 on both sides.

$5x^2=25$

Divide both sides by 5.

$x^2=5$

Taking square root on both sides.

$x=\pm \sqrt{5}$

(c)

$8-c^2=5$

Subtract 8 from both sides.

$-c^2=-3$

Multiply both sides by -1.

$c^2=3$

Taking square root on both sides.

$c=\pm \sqrt{3}$

Determine whether the data described below are qualitative or quantitative and explain why. The numbers of cases of flu treated

Zepler [3.9K]

Answer:

d) The data are quantitative because they consist of counts or measurements.

Step-by-step explanation:

The number of cases of flu treated at a certain hospital in different years consists in integer numbers (there cannot be 108.4 cases of flu treated in one year, just 107, 108, 109, etc).

Therefore the date are quantitative because the data consists of numbers which are counts of a certain number of individuals who were affected by the flu during different years.
