Answer: The answer is (2,4)

Hi! here the notation for a point is (x,y), so a reflection over the x axis will turn a point (x,y) in a reflected point (x, -y). This means that you change y for -y, and x stays the same.

Then if we have the point (2,-4), after the reflection in the x axis, we will get (2,-(-4)) = (2,4)

Find difference 7 7/8-3 1/4
umka2103 [35]
So first convert to improper fractions
7 and 7/8=7+7/8=56/8+7/8=63/8

3 and 1/4=3+1/4=12/4+1/4=13/4

so nowe we have
63/8+13/4
convert bottom number to same
which is 8
13/4 times 2/2=26/8
now we have
63/8-26/8=37/8=4 and 5/8
answer is 4 and 5/8

I’ve done question a. But can you help me on b and c
spin [16.1K]

Answer:

Step-by-step explanation:

b) Diameter of Mercury = 4.88 * 10³ = 4.88 * 1000 = 4880 km

Radius of Mercury = 4880÷ 2 = 2440 km

c) Mass of Jupiter = 1.898 * 10²⁷ = 18.98 * 10²⁶

Mass of Saturn = 5.68 * 10²⁶

Difference  = 18.98 * 10²⁶ - 5.68*10²⁶

                   = (18.98 - 5.68) * 10²⁶

                   = 13.30 * 10²⁶

                   = 1.330 * 10²⁷

Answer:

\sf\longmapsto \: x = 10

Step-by-step explanation:

Subtract 7 from both sides:

7−5x−7=−43−7

Simplify:

−5x=−50

Divide both sides by −5:

\sf\longmapsto \:  \frac{ - 5x}{ - 5}  =  \frac{ - 50}{5}

\sf\longmapsto \: x = 10
