What is the inverse

Solution 1

**Answer:**

the inverse is none hope this helps :)

Question

⦁ The average distance from the sun to the planet Mercury is about 58,000,000 km. The diameter of a human hair is about 0.0025 cm. ⦁ What is the distance from the sun to Mercury written in scientific notation?
⦁ What is the diameter of a human hair written in scientific notation?
⦁ In comparing the measurements in Parts (a) and (b), what else must be done before a comparison is made?
I have no idea what to answer our teacher hasent taught us this and its overdue please help

Solution 1

**Answer:**

The distance is 5.8x10^7 km

The diameter is 2.5x10^-3 cm

and before a comparison is made both numbers have to be written in the same unit. meaning the km has to be converted to cm or vice versa.

Solution 2

**Answer:**

distance is 5.8x10^7 km

The diameter is 2.5x10^-3 cm

**Step-by-step explanation:**

Question

Factor 2x^2+4x+18 !!!!!

Solution 1

**Answer: 2 ( x 2 + 2 x + 9 )**

**Step-by-step explanation:**

Solution 2

**Answer:**

No solution. The equation has no solution whether you do it by factorization or quadratic solving method.

Question

57 is what percent of 60

Solution 1

**the answer is 95% of 60**

Question

Mine their solutions. Explain your reasoning.
y = 2x + 2
y = 2x - 3

Solution 1

**Step-by-step explanation:**

2x+2=2x-3, substituting the first equation into the second one

2x-2x=-3-2, arranging like terms

0=/-5

this means we have no solution. The slash sign should be on the equal sign(0 not equal to -5).

Question

5y +6z2 - y3 ; y=4 z=5 (I can't input exponents; the 2 in 6z2 is an exponent, and the 3 in y3 is, too.)

Solution 1

5(4)+6(5)^2-(4)^3

20+150-64

170-64=106

20+150-64

170-64=106

Question

Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms. CA
a 3 93
12
b. 3 4 1
3 - 12 =
c. 3 4 1
T2 - 3 -
d. 4 12 4

Solution 1

**Answer:**

= =

**Step-by-step explanation:**

For two or more triangles to be congruent this implies that when compared, there exists a relationship among their angles and sides. They would have exactly the same three sides and exactly the same three angles. The relationship can be expressed in the following form: SSS (side-side-side) when all three corresponding sides are congruent, SAS (side-angle-side) when two sides and the angle between them are congruent and ASA (angle-side-angle) when two angles and a side are congruent.

The corresponding sides reduced to lowest terms are: = =

Solution 2

**Answer:**

**B.**

**Step-by-step explanation:**

**Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms. a 4/10=5/8=2/5. b 4/8=5/10=1/2. c 10/4=8/5=5/2.**

Question

Write an equation that gives the cost y of renting a car for x days from Rent All. 3 days cost $55.50 4 days $74 5 days $92.50 6 days $111.

Solution 1

Answer:

Step-by-step explanation:

One day cost $18.50

So

Number of days * 18.50 = total cost

Question

5+(x-5)=x justify each step

Solution 1

5+(x-5)=x

Simplify the left side by combining like terms:

5 + x - 5 = x

5-5 = 0

x = x

X = All real numbers.

Solution 2

**Answer:**

**5 + (x - 5) =x**

5 + x - 5 =x

5 - 5 = 0

0 = 0

**Step-by-step explanation:**

Question

Y = x + 3
2y = 2x + 6

Solution 1

**Answer:**

x=0

y=3

**Step-by-step explanation:**

2(x+3)=2x+6, substituting the first equation in the second

2x+6=2x+6, rearranging the equations

2x-2x=6-6

0=0

y=0+3

y=3
