Firstly mines 2x for 2 side
And combine 1 for 2 side
Result 6x^2+17x+5
So
(3x+1)(2x+5)=0
X=-1/3 or x=-5/2

Select the point that is a solution to the system of inequalities. y≤2x-2 y≤ x²-3x

miss Akunina [59]

Both statements are true. Therefore (4,2) is a solution and option D is correct.

The given inequalities are $y\leq 2x-2$ and $y\leq x^{2} -3x$ .

We need to select the point that is a solution to the system of inequalities (-2,-1), (1,3), (2,1) and (4,2).

<h3>What is an example of a system of inequalities in real life?</h3>

Inequalities can be seen in the speed limits on roads, the minimum age for seeing certain movies, and the distance you have to walk to go to the park. Inequalities represent a limit of what is permitted or achievable rather than a precise quantity.

Any point is a solution to this system of inequality if it satisfies both inequalities.

Check the inequalities by each option.

For (-2, -1), $-1\leq 2(-2)-2 \implies -1\leq -6$ .

This statement is false because -1 is greater than -6. Therefore (-2,-1) is not a solution and option A is incorrect.

For (1, 3), $3\leq 2(1)-2 \implies 3\leq 0$

This statement is false because 3 is greater than 0. Therefore (1,3) is not a solution and option B is incorrect.

For (2,1), $1\leq 2(2)-2 \implies 1\leq 2$ .

$1\leq 2^{2} -3(2) \implies 1\leq -2$

This statement is false because 1 is greater than -2. Therefore (2,1) is not a solution and option C is incorrect.

For (4,2), $2\leq 2(4)-2 \implies 2\leq 6$

$2\leq 4^{2} -3(4) \implies 2\leq 4$

Both statements are true. Therefore (4,2) is a solution and option D is correct.

What is the x-intercepts of the function f(x)=-2x2-3x+20

Dmitry [639]

Hey,
The x-intercepts are the coordinates where the line intercepts the x-axis.

x-intercepts: $( \frac{16}{3}, 0)$

The floor inside the horse barn is 45 feet long and 20 feet wide . The barn has 2 floors ( an upstairs and downstairs ) and both

Dahasolnce [82]

To find area we multiple length by width

20 times 45 is 900

then multiply that by 2 because there are two floors that are that size

900 times 2 is 1800

the total area for both floors is 1800 square feet

Eli is buying a townhouse that costs $276,650. He has $28,000 in savings and earns $4,475 a month. Eli would like to spend no mo

lutik1710 [3]

Answer:

The answer is: a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.

Step-by-step explanation:

If Eli wants to pay as little as possible, and we start with a 30-year mortgage, among the percentages that must be paid, the lowest is 3.5%, in terms of the fixed rate, the lowest is 5%, but if we see the amount of 30 years, it is 10%, so although the fixed rate of 6.5% is higher than that of 5%, the payment is only made once, and the difference is not so much compared to 10% for 30 years.

The answer is: a. 30 year FHA, 3.5% down at a fixed rate of 6.5%.
