djverab [1.8K]2 years ago
5 0

Step-by-step explanation:

9 ≤ |4x + 7|

9 ≤ 4x + 7

9 - 7 ≤ 4x

2 ≤ 4x

2/4 ≤ x

<h2>1/2 ≤ x</h2>

9 ≤ |4x + 7|

9 ≤ -(4x + 7)

9 ≤ -4x - 7

9 + 7 ≤ -4x

16 ≤ - 4x

16/-4 ≤ x

<h2>-4 ≤ x </h2>

<h2>{-4 ≤ x ≤ 1/2} </h2>

Find the length of an arc of 40° in a circle with an 8 inch radius.
lora16 [44]
The length of an arc is the fraction of its circumference based on the given intercepted angle. This is given by the equation,
                                  L (arc) = (Angle / 360) x 2πr
Substituting the known values,
                                  L (arc) = (40 / 360) x 2π(8 inch)  = 16π/9 inch
Thus, the length of the arc is approximately equal to 5.585 inches.

An angle measures 42 less than its complementary angle. What is measure of each angle?
yaroslaw [1]
First angle = x
Second angle = x - 42
Sum both complementary angles = 90

x+x-42=90
2x=132
x=66⁰    -  First angle
x-42=66-42=24 
24⁰ - Second angle

Solve the system 8y-5z=23 3y-2z=6<br><br> 100 POINTS
Hatshy [7]

Answer:

z = 21 ; y= 16

Step-by-step explanation:

first of all we have to isolate a variable.

In second expression we can obtain:

3y = 2z+6

y = 2/3 z + 2

now we have to substitute this value in the first equation and solve it

8(2/3z+2)-5z = 23

16/3z + 16 -5z = 23

16z +48 - 15z = 69

z = 21

now we have to substitute z in the second equation:

y = 2/3 (21) +2

y = 14+ 2 = 16

y = 16
