Answer:

14x² + 7y - 22

Step-by-step explanation:

Combine like terms.

5x² - 6y - 22 + 13y + 9x²

5x² + 9x² = 14x²

-6y + 13y = 7y

Reorder the terms.

14x² + 7y - 22

Hope that helps.

Answer:

S(-2, -3)

Step-by-step explanation:

Find the diagram attached below,=. Frim the diagram, the coordinate of R and T are (-5, 3) and (-1, -5) respectively. If the ratio of RS to ST is 3:1, the coordinate of S can be gotten using the midpoint segment formula as shown;

S(X, Y) = {(ax1+bx2/a+b), (ay1+by1/a+b)} where;

x1 = -5, y1 = 3, x2 = -1, y2 = -5, a = 3 and b =1

Substitute the values into the formula;

X = ax2+bx1/a+b

X = 3(-1)+1(-5)/3+1

X = -3-5/4

X = -8/4

X = -2

Similarly;

Y = ay2+by1/a+b

Y = 3(-5)+1(3)/3+1

Y = -15+3/4

Y = -12/4

Y = -3

Hence the coordinate of the point (X, Y) is (-2, -3)

Answer:

The probability that it will rain in atleast two consecutive days will be 0.167936.

Step-by-step explanation:

Since it rains on 40% of the days, then the probability of it raining on each day is

This follows a binomial distribution

Since it's a five-day tour and they want to know the probability that rain falls in atleast TWO CONSECUTIVE days then we have to consider 2 days as one, as we do in combination problems, so that they are always together before we use in our binomial probability density function.

Our Probability Density Function is given as

[tex]P(X) = \binom{n}{x} p^x \times q^{n-x}[/tex]

Where p is probability of raining and q = 1 - p is probability of not raining.

Our n is 4 since we are considering two days as one.

We are looking the P(X≥2) = 1 – P(X<2) = 1 – [P(X = 0) + P(X = 1).

[tex]P(X = 0) = \binom{4}{0} 0.4^0 \times 0.6^4 = 0.1296[/tex]

[tex]P(X = 1) = \binom{4}{1} 0.4^1 \times 0.6^3 = 4\times 0.4 \times 0.216 = 0.3456[/tex]

Therefore P(X≥2) = 1 – (0.1296 + 0.3456) = 0.5248.

Remember we combined two consecutive days that it will rain as one, their probabilities will be:

2! x 0.4 x 0.4 = 0.32

Therefore, the probability that it will rain in atleast two consecutive days will be

0.32 x 0.5248 = 0.167936

Answer:

E

Step-by-step explanation:

dy/dt = y² − 1

When -1 < y < 1, dy/dt is negative.  So the solution is decreasing between y = -1 and y = 1.

Only one graph is consistently decreasing in that range, and that's the last graph.

Answer:

[tex]Probability = \frac{1}{969}[/tex]

Step-by-step explanation:

Given

[tex]Members = 19[/tex]

[tex]Selection = 3[/tex]

Required

Determine the probability of selecting Jim, Bruce and Valerie

First, we need to calculate the possible number of selections.

This is calculated using combination formula:

[tex]Selection = ^nC_r[/tex]

[tex]Selection = ^{19}C_3[/tex]

[tex]Selection = \frac{19!}{(19-3)!3!}[/tex]

[tex]Selection = \frac{19!}{16!3!}[/tex]

[tex]Selection = \frac{19 * 18 * 17 * 16!}{16! * 3 * 2 * 1}[/tex]

[tex]Selection = \frac{19 * 18 * 17}{3 * 2 * 1}[/tex]

[tex]Selection = \frac{19 * 18 * 17}{6}[/tex]

[tex]Selection = 969[/tex]

Selection of Jim, Bruce and Valerie is only 1 selection of the 960 possible selection.

So:

[tex]Probability = \frac{1}{969}[/tex]

The probability that Jim, Bruce, and Valerie are selected in any​ order is [tex]\rm P=\dfrac{1}{969}[/tex] and this can be determined by using the given data.

Given :

Assume that Jim, Bruce, and Valerie are three of the 19 members of the​ class and that three of the class members will be chosen randomly to deliver their reports during the next class meeting.

In order to determine the probability that Jim, Bruce, and Valerie are selected in any​ order, first determine the total number of possible selections.

The total number of possible selections is given by:

[tex]\rm S = \; ^nC_r[/tex]

[tex]\rm S = \; ^{19}C_3[/tex]

[tex]\rm S = \dfrac{19!}{16! \times 3!}[/tex]

S = 969

So, the probability that Jim, Bruce, and Valerie are selected in any​ order is:

[tex]\rm P=\dfrac{1}{969}[/tex]

Answer:

50 feet

Step-by-step explanation:

The car's distance from the timekeeper us given by :

y = 293x+50

Where x is time in seconds and y is the distance from the timekeeper's position.

The general equation of a line is given by :

y = mx +c

On comparing, we get : c = 50

It means the timekeeper has covered 50 feets at the beginning.

Answer:x=22 over 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10−2(x−7)=4(x−5)

10+(−2)(x)+(−2)(−7)=(4)(x)+(4)(−5)(Distribute)

10+−2x+14=4x+−20

(−2x)+(10+14)=4x−20(Combine Like Terms)

−2x+24=4x−20

−2x+24=4x−20

Step 2: Subtract 4x from both sides.

−2x+24−4x=4x−20−4x

−6x+24=−20

Step 3: Subtract 24 from both sides.

−6x+24−24=−20−24

−6x=−44

Step 4: Divide both sides by -6.

−6x−6=−44−6

x=22 over 3

Step-by-step explanation:

Let suppose [tex]x[/tex] be the width of the rectangle.

As the length is 15 centimeters more than its width i.e.

[tex]length = x+15[/tex]

Therefore, the width of the rectangle will be:

[tex]x = length - 15[/tex]

CHECK BY EXAMPLE

Let suppose if the length of the rectangle is 20 cm.

Then the width of the rectangle will be:

x = length - 15

  = 20 - 15

   = 5 cm

Therefore, the width of the rectangle will be 5 cm.

Answer:

Slope=1

Step-by-step explanation:

Slope=y1-y2/x1-x2

Where x1,y1= (1, 1) and X2,y2=(-3, -3)

Slop=1+3/1+4

=4/4

=1

So the slope is 1.

Answer:

1

Step-by-step explanation:

Here,

x₁ = 1 and x₂ = (-3)

y₁ = 1 and y₂ = (-3)

Now,

Slope

= y₁ - y₂ ÷ x₁ - x₂

= ( 1 ) - (- 3) ÷ ( 1 ) - (- 3)

= 1 + 3 ÷ 1 + 3

= 4 ÷ 4 = 1

Thus, Slope is 1
