How to find the x intercept in slope intercept form

Answers

Answer 1

Answer:
-- The x-intercept is the point where the line crosses the x-axis.
-- 'Y' is zero at every point on the x-axis.
-- So y=0 at the x-intercept.

You say that you have the equation of the line, and it's in
slope/intercept form ?
      Y = mx + b
Great !

Just set y=0.   Then you have mx + b = 0 .
Solve that for 'x' , and you have the x-intercept.

(It turns out to be x = - b/m . Always true, and a very handy formula
to remember if you can, and then you always have the x-intercept at
your fingertips whenever you need it.)

Write a real-world problem that could be represented by the expression 3(23). Then explain how you could solve the problem mentally.

Answers

3(23) really means 3*23, or just 3 multiplied by 23. For example: "Jana has 23 dollars. Her friend John has $23, and his friend Jacob also has 23 dollars. How much money do they have all together?" To solve this problem mentally, you could break 3*23 into two numbers you're familiar with multiplying, like 20 and 3, and then add the numbers together. For example: 3*20 + 3*3. 3*20=60, 3*3=9, and 60+9=69. So, 3*23=69.

Robert sketches two rectangular prisms, A and B. Prism A's side lengths are 5 centimeters, 6 centimeters and 7 centimeters. Prism B's side lengths were twice those of prism A's: 10 centimeters,12 centimeters, and 14 centimeters. Robert says that surface area of prism B is twice the surface area of prism A. Is he correct? If he is not, how many times as great as prism A's surface area is prism B's surface area? Show your work.

Answers

fasle
LH=legnth times height
HW=height times width
LW=legnth times width
surface area=2(LH+LW+WH)

A surface area is 2(5*6+5*7+6*7)=214

b surface area is double everybody si
2(10*12+10*14+12*14)=856

214 times 2=428

he is wrong

how many times as great?
856/214=4

answer is 4 times
