Answers

Answer:

25/4

Step-by-step explanation:

7 can also be 7/1. Now you have 7/1-3/4. Multiply the denomiator to make them the same so you can subtract. 1*4=4 and 7*4= 28. Now you have 28/4-3/4. Subtract the numerators. 28-3=25. Your answer is 25/4. (6.25 if you need it in decimal form)

Help plzzz!! Find the slope through these pairs of points
(5,-15),(12,2)
(-18,-20),(6,-5)
(-18,-19),(-17,-19)
(-1,3),(-11,-17)

Answers

We can use the formula y2-y1/x2-x1 to find the slope.

1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.

2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.

3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.

4. -17-3/-11-(-1) is -20/-10. The slope is 2.

Step-by-step explanation:

What I did for these problems is plug in the numbers listed for the x-value. For example, in your calculator you’d put; (1/2)^3 and that’d get you 1/8. Then, try it for 8^(2 - 3) which is also 1/8. So, (1/2)^3 = 8^(2 - 3).

The same process for the second problem. 16^(2(7/3) -3) = 4^((7/3) + 1). This should give you 101.59…

solve the following equation: 0.4(g-2)+1.2=-(g-1)+2.9​

Answers

Answer: g = 2.5

Hope it helps!

Answer:

g = 2.5

Step-by-step explanation:

0.4(g - 2) + 1.2 = - (g - 1) + 2.9 ← distribute parenthesis on both sides

0.4g - 0.8 + 1.2 = - g + 1 + 2.9 ( simplify both sides )

0.4g + 0.4 = - g + 3.9 ( add g to both sides )

1.4g + 0.4 = 3.9 ( subtract 0.4 from both sides )

1.4g = 3.5 ( divide both sides by 1.4 )

g = 2.5
