What is 4 2/3 × 6 7/10​

Mathematics
1 answer:
Elodia [21]2 years ago
3 0

Answer:

31 \frac{4}{15}

Step-by-step explanation:

(convert the mixed numbers into improper fractions = a\frac{b}{c} = \frac{a*c+b}{c} )

\frac{4*3+2}{3}*\frac{6*10+7}{10}  

Steps if needed:

4*3 = 12+2 =14

6*10=60+7=67

\frac{14}{3} *\frac{67}{10}=\frac{14*67}{3*10}

= \frac{938}{30}

Simplify: Divide by 2

\frac{469}{15} || 938/2 = 469   30/2 = 15

Convert your answer to a mixed fraction

31\frac{4}{15}

469/15 = 31.26....

15*31 = 465

465+4 = 469

So your answer is 31 4/15

Which graph shows a function whose inverse is also a function?
never [62]

Answer: A good way to determine if a line represents a valid function is to use the vertical line test.

To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time.

If it is touching more than one point on the line at a time, the line is not a valid function.

The first line and its inverse both pass the test.

The second line passes the test, but its inverse does not.

The third line also passes the test, but again, its inverse does not.

The same applies to the fourth line and its inverse.

How to find an equation for a line through two given points?​
xz_007 [3.2K]

Answer:

The equation of the line is: y = 0.6x + 0.6

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

Two points:

We have these following two points in this exercise:

x = -6, y = -3, so (-6,-3)

x = 4, y = 3, so (4,3)

Finding the slope:

Given two points, the slope is given by the change in y divided by the change in x.

Change in y: 3 - (-3) = 3 + 3 = 6

Change in x: 4 - (-6) = 4 + 6 = 10

So

m = \frac{6}{10} = 0.6

Then

y = 0.6x + b

Finding b:

We replace one of the points in the equation to find b. I will use (4,3).

y = 0.6x + b

3 = 0.6*4 + b

2.4 + b = 3

b = 0.6

The equation of the line is: y = 0.6x + 0.6
