Select the correct answer. Which number best represents the slope of the graphed line?

A.-5

B.-1/5

C.1/5

D.5

Answer:

y = 0.3

Step-by-step explanation:

Solve for y:

[tex] \longrightarrow [/tex] (3.2y - 1.8) - (5.2 y + 3.4) = -5.8

-(5.2y + 3.4) = -5.2y - 3.4:

[tex] \longrightarrow [/tex]3.2y - 1.8 -5.2y - 3.4 = -5.8

Grouping like terms, 3.2y - 1.8 - 5.2y - 3.4 = (3.2y - 5.2y) + (-1.8 - 3.4):

[tex] \longrightarrow [/tex] (3.2y - 5.2y) + (-1.8 - 3.4) = -5.8

3.2y - 5.2y = -2 y:

[tex] \longrightarrow [/tex] -2y + (-1.8 - 3.4) = -5.8

-1.8 - 3.4 = -5.2:

[tex] \longrightarrow [/tex] -5.2 - 2y = -5.8

Add 5.2` to both sides:

[tex] \longrightarrow [/tex] (5.2 - 5.2) - 2y = 5.2 - 5.8

5.2 - 5.2 = 0:

[tex] \longrightarrow [/tex] -2y = 5.2 - 5.8

5.2 - 5.8 = -0.6:

[tex] \longrightarrow [/tex] -2y = -0.6

Divide both sides of -2y = -0.6 by -2:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{-2}{-2}y = \dfrac{-0.6}{-2} [/tex]

[tex] \sf \dfrac{-2}{-2} = 1: [/tex]

[tex] \longrightarrow [/tex] [tex] \sf y = \dfrac{-0.6}{-2} [/tex]

[tex] \sf \dfrac{-0.6}{-2} = 0.3: [/tex]

[tex] \longrightarrow [/tex] y = 0.3

Answer:

Approximately 15 tea hees

Step-by-step explanation:

Given that:

Number of teachers needed to Mark 500 exam papers in 30 hours =

Hence, marking rate of each teachers ;

500 / (30 * 10) = 500 / 300 = 1.667 papers per hour

If teachers mark at this rate, the number of teachers which will be required to mark 600 exam papers in 25 hours ;

Let number of teachers = t

(Rate * number of hours * number of teachers) = number of exam papers to be marked

(1.6667 * 25 * t) = 600

41.666665t = 600

t = 600 / 41.666665

t = 14.40000

Number of teachers needed = about 15 teachers

Compás binario de subdivisión binaria: 2/4

Compás de dos cuartos o compás de dos por cuatro. El numerador 2 indica que el compás se divide en dos partes y el denominador 4 indica por convención que en cada una de esas partes hay una negra. Por lo tanto en todo el compás entran dos negras.

Answer:

1. D (5 fruit baskets)

2. C (4)

3. B (-10)

Step-by-step explanation:

1.  Subtract 30 from 105 to get 75, as this is how much she paid for the annual membership fee. Then divide 75 by 15, this being the cost of the fruit baskets. Your answer would be 5, because 75/5=15.

2. Subtract 5 from 21. This would give you 16. Now you need to find out which number you would need to equal that 16. So 4x?=16. The answer would be 4.

3. Figure out what 5x? would need to be to get to -50. This would be -10, as -10x5=-50. Then just add in the 2, and since you're adding the positive 2 to a negative number, the negative number would be closer to 0, so -48.

Answer:

[tex] y = 8 [/tex]

Step-by-step explanation:

Equation of the line that passes through (-2, 8) with a slope of 0, can be written in point-slope form, [tex] y - y_1 = m(x - x_1) [/tex] and also in slope-intercept form, [tex] y = mx + b [/tex].

Using a point, (-2, 8) and the slope (m), 0, substitute x1 = -2, y1 = 8 and m = 0 in [tex] y - y_1 = m(x - x_1) [/tex].

Thus:

[tex] y - 8 = 0(x - (-2)) [/tex]

[tex] y - 8 = 0 [/tex]

Rewrite in slope-intercept form

[tex] y - 8 + 8 = 0 + 8 [/tex] (addition property of equality)

[tex] y = 8 [/tex]

Answers:

Larger bottle = 44 gallons

Smaller bottle = 33 gallons

=====================================================

Explanation:

L = capacity of larger bottle

S = capacity of smaller bottle

Capacities are in gallons

We're told the ratio of these capacities is 4 to 3, meaning L/S = 4/3. Note how L goes first on top since 4 is the first number and it's larger than 3.

Cross multiply to get 3L = 4S. We can solve for S to get S = 3L/4.

----------------------------

We're also told that the larger bottle has 11 more gallons than the smaller one, so,

Larger = Smaller + 11

L = S+11

L = (3L/4) + 11 .... plug in S = 3L/4

4L = 4*(3L/4) + 4*11 ... multiply every term by 4

4L = 3L + 44 .... the fraction goes away afterward

4L-3L = 44 .... subtract 3L from both sides

L = 44

The larger bottle can hold 44 gallons

S = 3L/4

S = 3*44/4

S = 3*11

S = 33

The smaller bottle can hold 33 gallons

Note that L-S = 44-33 = 11 to show there's an 11 gallon difference between the larger and smaller bottles. We can also see that L/S = 4/3 is also true because 44/33 = 4/3. This confirms our answers.
