Answer:

The middle value of the interval is 4.58

Step-by-step explanation:

Consider the provided interval.

We need to find the value that is in the middle of the interval.

We can find the middle value of the interval by adding the upper and lower limit and divide the sum of the upper and lower limits by 2.

Here the upper limit is 3.27 and lower limit is 5.89.

\frac{3.27+5.89}{2}=\frac{9.16}{2}=4.58

Hence, the middle value of the interval is 4.58

The potential solutions to the radical equation are a = −4 and a = −1. Which statement is true about these solutions? The soluti
inessss [21]

Answer:

Both a = −4 and a = −1 are true solutions

Step-by-step explanation:

Given

\sqrt{a + 5} = a + 3

a = -4; a = -1

Required

The true statement about the solutions

We have:

\sqrt{a + 5} = a + 3

Square both sides

a + 5 = (a + 3)^2

a + 5 =a^2 + 6a + 9

Collect like terms

a^2 + 6a - a + 9 - 5 = 0

a^2 + 5a + 4 = 0

Expand

a^2 + 4a + a + 4 = 0

Factorize

a(a + 4) + 1(a + 4) = 0

Factor out a + 4

(a + 1)(a + 4) = 0

Split:

a + 1 = 0; a + 4 = 0

Solve:

a =-1; a = -4

Match each inequality with the correct solution.
Alex73 [517]

Answer:

a. and iii

b. and i

c. and iv

d. and ii

Step-by-step explanation:

a. -\frac{3}{2}x + 12 > 15 = x > -2

           - 12  - 12

 -\frac{3}{2}x > 3

2(  -\frac{3}{2}x = 3)

-3x > 6

/-3    /-3

x > -2

b. 4x + 12 < 20 = x <2

        - 12   - 12

 4x < 8

 /4    /4

  x < 2

c. -8x < 16 = x > -2

   / -8   /-8

  x > -2

d. 55 < 35 + 10x = x > 2

  -35   -35

   20 < 10x

   /10   /10

   2 < x = x > 2

Hope that helps!
