Identify Slope and Y intercept for the equation X=4 M=B=

krek1111 [17]

Undefined and Undefined

Since the equation is x = 4, there is no y-intercept as x will never equal 0.

Additionally, since the equation is x = 4, there is no change in x value and as such the slope can not be determined.

help me please can someone please help i beg you. i have to say why this is wrong and solve this correctly. i beg you please

Answer:

The person solving the problem first subtracted 6 from 15. Since the cube root is next to the six, the problem should be read as $15-6(\sqrt[3]{\frac{-1000}{27} } )$ rather than $(15-6)(\sqrt[3]{\frac{-1000}{27} } )$ .

To solve it correctly, first find the cube root of -1000/27: <u>-10/3</u>
Next, multiply by 6: -20
Finally, subtract from 15: 35

please lmk if anything is wrong with my answer, hope this helps :)

$-\displaystyle\frac{1}{2} :1\frac{3}{4}$

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .

Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .

So now our maths problem looks as follows :

$-\displaystyle\frac{1}{2} :\frac{7}{4}$
