Answer:  a) 6      b) 11.53     c) the smallest number of significant digits is 4

<u>Step-by-step explanation:</u>

a)

Complete the subtraction and addition (you can do this manually by lining up the decimal ... or... using a calculator)

2.784 - 3.00079 + 10.671 + 1.0798 = 11.5340  

→ there are 6 digits in the answer

b & c)

2.784            has 4 significant digits

3.00079       has 6 significant digits

10.671           has 5 significant digits

1.0798          has 5 significant digits

→ the smallest number of significant digits is 4 so round the answer from part a to 4 significant digits:  \large\boxed{11.53}

What is the equation of the line AB, if it passes through (-4,0), and is parallel to the line
Karo-lina-s [1.5K]

Rewriting the equation of the given line in slope-intercept form,

-x-4y=1\\\\-4y=x+1\\\\4y=-x-1\\\\y=-\frac{1}{4}x-\frac{1}{4}

From this, we know the slope of the given line is -1/4.

Since parallel lines have the same slope, we know the line whose equation we want to find has a slope of -1/4.

Substituting into point-slope form,

y=-\frac{1}{4}(x+4)\\\\\boxed{y=-\frac{1}{4}x-1}

Point G is between F and H. FH= 102, FG=5x+9, and HG=9x-5
dexar [7]

a)

FH = 102, FG = 5x + 9. HG = 9x - 5     <em>Given</em>

  FG    +   HG   =    FH                        <em>Segment addition postulate</em>

5x + 9 + 9x - 5 =  102                         <em>Substitution</em>

            14x + 4 = 102                        <em>Simplify (added like terms)</em>

                  14x = 98                          <em>Subtraction property of equality</em>

                     x = 7                             <em>Division property of equality</em>

b)   FG = 5x + 9  = 5(7) + 9   = 35 + 9   = 44

c)   HG = 9x - 5   = 9(7) - 5   = 63 - 5   = 58

Answers: a = 7, b = 44, c = 58
