Mathematics
1 answer:
Dima020 [189]2 years ago
4 0

Answer:

=-1\frac{1}{2}

Step-by-step explanation:

Given the following question:

-3\frac{3}{4} \div2\frac{1}{2}

In order to find the answer, we first convert the mixed numbers into improper fractions. Then we use KCF (Keep, Change, Flip) and solve.

-3\frac{3}{4} \div2\frac{1}{2}
-3\frac{3}{4} =12+3=-\frac{15}{4}
2\frac{1}{2}=2\times2=4+1=\frac{5}{2}
-\frac{15}{4} \div\frac{5}{2}
-\frac{15}{4} \times\frac{2}{5}
15\times2=30
4\times5=20
=-\frac{30}{20}
-\frac{30}{20} \div10=-\frac{3}{2}
-\frac{3}{2}=3\div2=-1\frac{1}{2}
=-1\frac{1}{2}

Hope this helps.

Here goes another question
nlexa [21]

Answer:

y = x - 8

Step-by-step explanation:

In order to solve this, we need to use point-slope form.:

y - y1 = m(x - x1)

Substitute the numbers into the equation:

y - (-8) = 1(x - 0)

y + 8 = x

y = x - 8

Given the function f(x) = 2x+4 and the domain: {-1,0,1},determine the range
Svetlanka [38]

Answer:

f(x) = 2x + 4 domains {-1, 0, 1}

range {2, 4, 6}

(please mark brain if this helps and is correct)

Step-by-step explanation:

to solve f(x) to find the range you would want to input all the domain numbers in the equation f(x) to get the range of all the numbers you need

step 1: take the first domain number and input it into your equation where x is

ex: 2x + 4   [2(-1) + 4] = -2 + 4 = 2

step 2: add the second domain number and input it into your equation where x is

ex: 2x + 4   [2(0) + 4] = 0 + 4 = 4

step 3: add the last domain number and input it into your equation where x is

ex: 2x + 4   [2(1) + 4] = 2 + 4 = 6

Now we have determined what the range is

notka56 [123]

Answer: The potential energy decreases and the kinetic energy increases

Step-by-step explanation:

When a body is at rest , the Potential energy is maximum because the body is not moving and the acceleration is therefore zero but as soon as the body starts moving , it will convert the potential energy to kinetic energy , therefore the kinetic energy will therefore increase.
