plug in the numbers- (0+7)/(-5-1)

Answer:

t=12.5s

Step-by-step explanation:

s(t) = 50t - 2t^2

v(t) = 50 - 4t

a(t) = -4

When v(t) = 0, the car stops.

v = u +at

0 = 50 + (-4)t

t = 12.5

Answer: the slope intercept form of 2x+y=6 is y=-2+6

Step-by-step explanation:

2x+y=6  (subtract 2x from both sides)

-2x    -2x  (the -2x and the 2x cancel leaving...)

y=-2x+6  →( y equals negative two x plus six)

Step-by-step explanation:

1) [tex]\frac{1}{3}-(\frac{1}{3}*\frac{1}{3}) + (\frac{1}{3}[/tex] ÷[tex]\frac{1}{3}) =[/tex] [tex]\frac{1}{3}-\frac{1}{9} +(\frac{1}{3}*\frac{3}{1})[/tex]

                                  [tex]=\frac{1}{3}-\frac{1}{9}+1\\\\=\frac{1*3}{3*3}-\frac{1}{9}+\frac{1*9}{1*9}\\\\=\frac{3}{9}-\frac{1}{9}+\frac{9}{9}\\\\=\frac{3-1+9}{9}\\\\=\frac{11}{9}\\\\=1\frac{2}{9}\\[/tex]

2)

 [tex](3\frac{3}{4}-2\frac{2}{3})*1\frac{1}{2}=(\frac{15}{4}-\frac{8}{3})*\frac{3}{2}\\\\=(\frac{15*3}{4*3}-\frac{8*4}{3*4})*\frac{3}{2}\\\\=(\frac{45}{12}-\frac{24}{12})*\frac{3}{2}\\\\=(\frac{45-24}{12})*\frac{3}{2}\\\\=\frac{21}{12}*\frac{3}{2}\\\\=\frac{21}{4}*\frac{1}{2}\\\\=\frac{21}{8}\\\\=2\frac{5}{8}[/tex]

3) When finding equivalent fractions both numerator and denominator should be multiplied with the same number. But  Lethna didn't multiply with the numerator.

[tex]\frac{2}{5}+\frac{1}{2}=\frac{2*2}{5*2}+\frac{1*5}{2*5}\\\\=\frac{4}{10}+\frac{5}{10}\\\\=\frac{9}{10}[/tex]

4) In fraction multiplication convert mixed fraction to improper fraction and reduce to smallest term

[tex]1\frac{1}{2}*5\frac{1}{3}=\frac{3}{2}*\frac{16}{3}\\\\=8[/tex]

5)

[tex]8\frac{2}{3}*5\frac{4}{9}=\frac{26}{3}*\frac{49}{9}\\\\=\frac{1274}{27}\\\\= 47\frac{5}{27}\\\\[/tex]

6) Use Keep Change Flip (KCF) method for fraction division

[tex]4\frac{2}{5}[/tex] ÷ [tex]6\frac{5}{8}[/tex] = [tex]\frac{22}{5}[/tex] ÷ [tex]\frac{53}{8}[/tex]

          [tex]= \frac{22}{5}*\frac{8}{53}\\\\=\frac{176}{265}[/tex]

Step-by-step explanation:

Answer:

1) The equation that has infinitely many solution is y = -8/11·x + 4

2) The equation of the graph that has no solution is y = -8/11·x + 1

3) The equation of the line that has only one solution is y  = -1/4·x + 2

Step-by-step explanation:

1) The points on the graph are;

(0, 4), and (5.5, 0)

The slope of the line defined by the given two points, we have;

(0 - 4)/(5.5 - 0) = -40/55 = -8/11

The equation of the straight line graph in point and slope form, we have;

y - 4 = -8/11 × (x - 0)

y - 4 = -8/11·x

For the equation for the system that has infinitely many solution, we have;

y = -8/11·x + 4

2) For the equation whose graph foes through the point (0, 1) and the system has no solution, we have;

An equation that has no solution with the equation y = -8/11·x + 4, is parallel to y = -8/11·x + 4, and therefore, the slope are equal

Therefore, the equation whose graph foes through the point (0, 1) and the system has no solution, in point and slope form is given as follows;

y - 1 = -8/11 × (x - 0)

y - 1 = -8/11·x

The equation of the graph that has no solution is therefore;

y = -8/11·x + 1

3) For the equation of the graph that goes through the point (0, 2), and has a common solution with the system at (4, 1), we have;

The slope of the graph is (1 - 2)/(4 - 0) = -1/4

The equation of the line that has only one solution with the system in point and slope form is given as follows;

y - 2 = -1/4×(x - 0)

y - 2 = -1/4·x

The equation of the line that has only one solution in standard form is therefore;

y  = -1/4·x + 2

the sign flips when you divide by a negative

9514 1404 393

Answer:

  z ≥ 3

Step-by-step explanation:

When you divide by the negative coefficient of z, you reverse the inequality symbol:

  -8z ≤ -24

  z ≥ -24/-8 . . . . divide by -8

  z ≥ 3

This graphs as a solid dot at 3, with the line extending to the right (to greater values).

Answer:

[tex]\frac{0}{4} x[/tex]

Step-by-step explanation:

We can use the equation: [tex]\frac{-4}{-4} \frac{-(-4)}{-(-8)}[/tex]

After solving, we get [tex]\frac{0}{4} x[/tex].

This means that the equation of the line is y = -4. This is a horizontal line moving infinitely in both directions with a constant y-value of -4.

Answer:

Step-by-step explanation:

To solve this, we will create a proportion.

The proportion will show the ratio of ABC to EDC and allow us to solve for x.

20 - x / 20 =  x / 5

100 -  5x = 20x

100 - 5x + 5x = 20x + 5x

100 = 25x

100 / 25 = 25x / 25

Answer:

a) y = 0.55x + 75

b) $108

Step-by-step explanation:

a) to find the equation represent the sequence use the y=mx+b formula

y = total price

m = cost per mile

x = miles driven

b = flat fee

Therefore y = 0.55x+75

b) To figure out the cost of driving 60 miles you use the equation y = 0.55x + 75

y = 0.55 X 60 + 75

= 108

Therefore the cost of renting the truck and driving 60 miles is $108

Answer:

similar; AA similarity; RQP

Step-by-step explanation:

We know that angle R is congruent (equal) to angle C.

We know that angle Q is congruent to angle B.

Because they ordered their triangle statement CBA, and we know that R matches C and Q matches B, you should order your statement as RQP.

Answer:

C / 20

Step-by-step explanation:

Number of students in the baking club = 10

Each student made 2 chocolate cakes

Total cakes = number of students × number of cakes per student

= 10 × 2

= 20

Total cups of flour used by 10 students = C cups

Amount of flour for one cake = Total cups of flour / Total cakes

= C / 20

The expression that represents the amount of flour for one cake = C / 20
