(3, - 2)

given y = - 2, then

- 2x + 4 = - 2 ( solve for x )

subtract 4 from both sides

- 2x = - 6 ( divide both sides by - 2 )

x = $\frac{-6}{-2}$ = 3

Answer:

The solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .

Option (D) is correct .

Step-by-step explanation:

As given the equations are .

4x+y=5

3x+y=3

Subtracted 3x+y=3 from 4x+y=5 .

Thus

4x - 3x + y - y = 5 - 3

x = 2

Put in the equation 4x+y=5 .

4 × 2 + y = 5

8 + y = 5

y = -8 + 5

y = -3

Therefore the solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .

Option (D) is correct .

Hungary's ratio of female to male athletes is 5:9. If Hungary brought 25 female athletes, how many

gulaghasi [49]

Answer:

Let the number of females and males be 5x and 9x respectively.

Given - number of females = 25

Therefore ,

$5x = 25 \\ x = \cancel \frac{25}{5} = 5$

Then ,

$number \: of \: males = 9x \\ = > 9(5) \\ = > 45$

After solving $|8-3p|\geq 2$ we get $p\geq \frac{10}{3}\,\, or\,\,p\leq 2$

So, Option A is correct.

Step-by-step explanation:

We need to solve the expression:

$|8-3p|\geq 2$

For solving, we apply the rule that:

if |u| ≥ a and a > 0 then, u ≤ -a and u ≥ a

Applying the rule:

$|8-3p|\geq 2\\8-3p\leq -2 \,\, and\,\,8-3p\geq 2\\$

$8-3p-8\leq -2-8 \,\, or\,\,8-3p-8\geq 2-8\\-3p\leq -10 \,\, or\,\,-3p\geq -6\\Multiply\,\,both\,\,sides\,\,by\,\,-1 (reverse\,\,the\,\,inequality\\3p\geq 10\,\, or\,\,3p\leq 6\\p\geq \frac{10}{3}\,\, or\,\,p\leq\frac{6}{3}\\p\geq\frac{10}{3}\,\, or\,\,p\leq 2$

After solving $|8-3p|\geq 2$ we get $p\geq \frac{10}{3}\,\, or\,\,p\leq 2$

So, Option A is correct.
