Answer:

y=1/4-3/4y

Step-by-step explanation:

rearrange the equation

4y=1-3x

divide both sides by 4 to get the value of y

Answer:

y = 1/4

Step-by-step explanation

Find Y set x=0

3(0)+4y = 1

        4y = 1

Step-by-step explanation:

The break-even point is on both curves. The y-intercept can be used for the other point in each case.

The break-even point is where cost and revenue are the same:

  20/3x +50 = 10x

  50 = 10/3x . . . . . . . . subtract 20/3x

  15 = x . . . . . multiply by 3/10

  r = c = 10(15) = 150 . . . . for x = 10

Two points you can use for graphing the lines are ...

  cost: (0, 50) and (15, 150)

  revenue: (0, 0) and (15, 150)

Answer:

y=mx+b

Answer: Since corresponding angles of parallel lines cut by a transversal are congruent, ADE = ABC and AED = ACB. So, based on the AA criterion for similarity, ABC ~ ADE.

Step-by-step explanation: Sample answer from Edmentum! Hope It helps :)

The triangle ADE is similar to the triangle ABC.

Similar triangles are triangles whose corresponding lengths are not equal to each other, but their corresponding angles are equal.

It is given that the line segment DE is parallel to BC.

Since it is parallel to each other, we can say that the angles formed on both the line segments are equal to each other since they are corresponding angles. Angle A is common to both the triangles.

Therefore, we can say that the two triangles are similar because all the angles are the same in each triangle.

Therefore, we have found out that the triangle ADE is similar to the triangle ABC.

Answer:

B

Step-by-step explanation:

We have the compound inequality:

[tex]5x+7\leq-3 \text{ or } 3x-4\geq 11[/tex]

Since this is an “OR” inequality, we can solve each inequality individually. So:

1)

We have:

[tex]5x+7\leq-3[/tex]

Subtract 7 from both sides:

[tex]5x\leq -10[/tex]

Divide both sides by 5:

[tex]x\leq-2[/tex]

So, the first solution is above.

2)

We have:

[tex]3x-4\geq 11[/tex]

Add 4 to both sides:

[tex]3x\geq15[/tex]

Divide both side by 3:

[tex]x\geq5[/tex]

Our second solution is above.

Therefore, our solution is:

[tex]x\leq -2 \text{ or } x\geq5[/tex]

Since our original inequality is “OR,” our solution set remains an “OR.”

Hence, our answer is B.

Answer: use your 5 times tables.

Step-by-step explanation:

5, 10 15, 20 25, 30, 35, 40

then count how many times it gotyou to 40

it took 8 times to get to 40.

Step-by-step explanation:

- A single coin is known to have 2 sides (The head H and the tail T).

The total number of sample space for n number of coins is expressed as 2ⁿ where

n is the total number of coins flipped.

If a single coin is flipped four times, the total outcome will be expressed as;

2⁴ = 16

Hence there are 16 different possible outcomes.

- To construct the sample space (the 16 possible outcomes)

For one flipped coin, the sample space is represented by the set S₁

S₁ = {H, T}

H is Head

T is Tail

For two flipped coin, the sample space is represented by the set S₂

S₂ = S₁×S₁

S₂ = {H, T}×{H,T}

S₂ ={HH, HT, TH, TT}

For three flipped coin, the sample space is represented by the set S₃

S₃ = S₂×S₁

S₃ = {HH, HT, TH, TT}×{H,T}

S₃ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

For four flipped coin, the sample space is represented by the set S₄

S₄ = S₃×S₁

S₄ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}×{H,T}

S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT}

Hence the sample space for a single coin flipped 4times is given by the set;

S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT}  where;

n(S₄) = 16

Answer:

Since p is > α we fail to reject the Null as the result is not significant at α = 0.05

Step-by-step explanation:

Given that:

Mean lifetime (m) = 1200

Sample size (n) = 25

Sample mean (x) = 1180

Standard deviation (s) = 80

α = 0.05

The null hypothesis :

H0 : m = 1200

Alternative hypothesis : m ≠1200

The t statistic :

(x - m) / (s/√n)

(1180 - 1200) / (80 / √25)

-20 / (80/5)

= - 1.250

P value = 0.10565 ( p value calculator)

Reject Null hypothesis if p > α

At α = 0.05

Since p is > α we fail to reject the Null as the result is not significant at α = 0.05

Answer:

1. x-5=3x-45

2. x=20

3.Perimeter is 45 units since each side is 15 units.

Step-by-step explanation:

x-5=3x-45

-5=2x-45

40=2x

x=20

So AB is 15 and AC and BC is also 15 since it is equilateral. 15+15+15=45 The perimeter is 45 units.

Answer:

Step-by-step explanation:

2x+51=4x+19

32=2x

x=16. The weight is 16 pounds

plug it back in to find the cost

32+51=83. 64+19 = 83. The cost is 83 dollars

Answer:

x = -11

Step-by-step explanation:

Well the two equations add up to 180 because they are a linear pair.

x + 56 + x + 146 = 180 (collect like terms)

2x + 202 = 180 (subtract 202 on both sides)

2x = -22 (divide by 2 on both sides)

x = -11

Answer:

[tex]\frac{0.5}{4}[/tex]

Step-by-step explanation:

An entire pizza would be represented by the percentage of 100% or the fraction [tex]\frac{100}{100}[/tex]. If we divide this pizza into 4 equal parts that would make one slice  a fraction represented as  [tex]\frac{25}{100}[/tex] or simplified to [tex]\frac{1}{4}[/tex]. If we now divide this one slice into two equal parts we would divide that fraction by 2 which would give us a new fraction, which would be [tex]\frac{0.5}{4}[/tex]. Represented as a percentage this would mean that this slice is 12.5% of the entire pizza.
