Answer:
x = -5.6 ±sqrt(1.75)
x≈-4.28 x≈-6.92
Step-by-step explanation:
(x + 5.6)^2 = 1.75
Take the square root of each side
sqrt((x + 5.6)^2) = ±sqrt(1.75)
x+5.6 = ±sqrt(1.75)
Subtract 5.6 from each side
x+5.6 -5.6 = -5.6 ±sqrt(1.75)
x = -5.6 ±sqrt(1.75)
x= -5.6 + sqrt(1.75) x = -5.6 - sqrt(1.75)
x≈-4.27712 x≈-6.92288
x≈-4.28 x≈-6.92
Answer:
Index numbers are intended to measure the degree of economic changes over time. These numbers are values stated as a percentage of a single base figure. Index numbers are important in economic statistics. ... Index numbers are intended to study the change in the effects of such factors which cannot be measured directly.
-3 ≤ 6x - 6 < 39 (seperate into two inequalities)
6x - 9 ≥ -3
6x - 9 < 39 (solve the inequalities)
x ≥ 1
x < 8 (find the intersection)
x ∈ { 1 , 8 }
Answer:
13/1*7/4
Step-by-step explanation:
The way you get this is by using the Keep, Change, Flip Method. 13 as a fraction would be 13/1, and this is the keep phase. The change phase is where you change division to multiplication. The flip phase is when we flip the numerator and denominator. Remember, this only works when dividing fractions.

A slope is a surface of which one end or side is at a higher level than another; a rising or falling surface.
"he slithered helplessly down the slope"
Some real life examples of slope include: in building roads one must figure out how steep the road will be. skiers/snowboarders need to consider the slopes of hills in order to judge the dangers, speeds, etc. when constructing wheelchair ramps, slope is a major consideration.
