The ordered pair(5,-3) is a solution to which of the following inequalities? a. y≥−2x+8 b. −2y<3x−9 c. y−2x>5 d. 4y+2x≤−1

stiks02 [169]

Answer:

Option d. $4y+2x\leq -1$

Step-by-step explanation:

we know that

If a ordered pair is a solution of an inequality, then the ordered pair must be satisfy the inequality

Verify each case

case a) $y\geq2x+8$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$-3\geq2(5)+8$

$-3\geq18$ -----> is not true

therefore

the ordered pair is not a solution

case b) $-2y$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$-2(-3)$

$6$ -----> is not true

therefore

the ordered pair is not a solution

case c) $y-2x>5$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$-3-2(5)>5$

$-13>5$ -----> is not true

therefore

the ordered pair is not a solution

case d) $4y+2x\leq -1$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$4(-3)+2(5)\leq -1$

$-2\leq -1$ -----> is true

therefore

the ordered pair is a solution

an orange was divided into 10 equal section. lily ate 4 sections. manny and Emma ate the remaining section. what fraction of the

salantis [7]

Answer:

Emma and Manny ate 3/10ths of the orange

Step-by-step explanation:

Lily ate 4 sections so that means 6/10ths of the orange is left.

Emma and Manny want to share the rest of the orange equally. So divide 6 by 2 and get 3. So 3/10ths for each of them.

Write the equation of the circle with center (3, 2) and with (9, 3) being a point on the circle. A) (x − 3)2 + (y − 2)2 = 13 Eli

Alexus [3.1K]

Answer:

D) (x - 3)^2 + (y - 2)^2 = 37

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is

(x - h)^2 + (y - k)^2 = r^2

We are given the center (3, 2), so we have h = 3, and k = 2.

The equation is now:

(x - 3)^2 + (y - 2)^2 = r^2

We need to find the radius.

The radius of a circle is the distance from the center of the circle to any point on the circle. We know the center, (3, 2), and we know a point on the circle, (9, 3). We can use the distance formula to find the distance between the center and that point which is the radius of the circle.

d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

d = sqrt[(9 - 3)^2 + (3 - 2)^1]

d = sqrt(6^2 + 1^2)

d = sqrt(37)

Now that we have the radius, we apply it to the equation of the circle.

(x - 3)^2 + (y - 2)^2 = (sqrt(37))^2

(x - 3)^2 + (y - 2)^2 = 37

Answer: D) (x - 3)^2 + (y - 2)^2 = 37
