Using the property find the sum: (4/3 + 3/5 + "-2/3" + "-11/5)"

Answers

Answer:

-14/15

Step-by-step explanation:

First the denominator must be the same so mutiply three with 5 to get 15. Don't forget to mutiply numrator!

After that, sump up the first numerator and second numerator because both are plus so you will get 29

Then, sum up the third numrator and forth numrator because both are minus so you will get -43.

Finally, you have 29 + -43 by 15.

You have to substract small number from large number so you will get -14. We use minus sign because -43 is larger than 29.

The result of (4/3+3/5+-2/3+-11/5) -87/15 or -5.8

Slope of 1/2 and x-intercept of 4

Answers

Answer:

y intercept is -2 or y=1/2x-2

Step-by-step explanation:

Plot the x intercept on a graph and use the rise over run until you get to the y int.

Sorry that it's confusing, but I hope this helped.

Final answer:

The line with a slope of 1/2 and an x-intercept of 4 is represented by the equation y = 1/2x - 2.

Explanation:

The subject of your question is the slope-intercept form of a linear equation, specifically involving a slope of 1/2 and an x-intercept of 4. To find the equation of a line, the most common form used is the slope-intercept form y = mx + b, where 'm' is the slope and 'b' is the y-intercept. Here you've been given the slope, m = 1/2, and the x-intercept (the value of 'x' when 'y' equals zero).

Therefore, at the x-intercept, y = 0, so 0 = 1/2(4) + b. Solving this for b gives us the y-intercept which can then be substituted back into the equation y = mx + b to give the full equation of the line.

So, let's begin by substituting the x-intercept into the equation: 0 = 1/2 * 4 + b, which simplifies to 0 = 2 + b. Solving for b, we get b = -2. Substituting slope and y-intercept into the equation gives us the final equation of the line: y = 1/2x - 2. This is the equation of the line with a slope of 1/2 that crosses the x-axis at the point (4,0).

One angle is 10 less than four times another angle. If the two angles are supplementary what is the measure of each angle? Find the correct equation one can use to solve this problem.Question 6 options:

a)

(x−10)+x=180

b)

(4x−10)+x=180

c)

4x+10=180

d)

x+(4x−10)=90

Answers

Supplementary angles must add up to 180. Let x equal "another angle." "One angle" is ten less than four times x. This would look like: 4x-10. 4x-10 and x must add up to 180: (4x-10) + x =180. This is choice B.

In Chemistry class, Andrew has earned scores of 64, 69, and 73 on three tests. He must maintain an average of 70 to pass the course. What score must Andrew earn on the final exam to pass the course?

Answers

$64+69+73 = 206$

$(206+x)/(4) =70$

$206+x=280$

$x=74$
