Write the slope intercept form that satisfies the following conditions
Olin [163]

y = 3x - 13

Step-by-step explanation:

The line will have the same slope as the given line, which is m = 3. Therefore, the equation of the line in its slope-intercept form is

y = 3x + b

Next we need to solve for b by plugging in the coordinates of the given point:

(-4) = 3(3) + b \Rightarrow b = -13

So the equation of the line is

y = 3x - 13

Four percent of Jennie's skin cells were burned when she escaped from a fire. If 3.7 x 10^10 of her skin cells were burned then,
baherus [9]

Answer:

355.2

Step-by-step explanation:

Given:

Four percent of Jennie's skin cells were burned

Total skin cells having Jennie = 3.7 x 10^10

                                                  = 3.7\times10\times10 = 370

To find:

How man skin cells were not burned ?

Solution:

Total skin cells having Jennie = 370

Percent of Jennie's skin cells were burned = 4%

Skin cells burned  from a fire = 370 \ of 4\%

                                                = 370\times\frac{4}{100} =\frac{1480}{100}

                                                = 14.8

Remaining skin cells which not burned = 370 - 14.8 = 355.2

Therefore,  355.2 skin cells were not burned.
