Mathematics
1 answer:
NemiM [27]3 years ago
6 0

Answer:

f(-4) = -12

Step-by-step explanation:

f(x)=2x-4

To calculate f(-4), we need to substitute x in our equation above with -4:

f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12

Note that 2*(-4) = -8

Answer: f(-4) = -12

sweet-ann [11.9K]

Answer:

if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.

Step-by-step explanation:

If your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, the chance that she might follow the instructions she receives is less 50 percent. In other words:

                                      Chance < 50%

The reason is that children at this age may have challenging time figuring out the subject when you may instruct certain things to do, as the sentences could be tricky for the children to decode the meaning.  

So,  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.

What is the equation of the line that passes through (-3, -1) and has a slope of 2/5? Put your answer in slope-intercept form.
Zanzabum
Hi there!

The general formula of A line in slope-intercept form is the following:
y = mx + n

In this formula m represents the slope of the line. Therefore, we can conclude that m = 2/5.
y =  \frac{2}{5} x + n

We also know that the line passes through the point (-3, -1) and we can therefore substitute this coordinate into the formula of the line.
x = -3 and y = -1

- 1 =  \frac{2}{5}  \times  - 3 + n

Multiply first.
- 1 =  -  1\frac{1}{5}  + n

And finally add 1 1/5 to both sides of the equation.
\frac{1}{5}  = n

We can now switch sides.
n =  \frac{1}{5}

Now we've found our value of n, which we can substitute into the formula of our line. Hence, in slope-intercept form, we find the following:
y =  \frac{2}{5}  x  +  \frac{1}{5}
