Answer:

x = 12 and y = -9

                                            Explanation:

Given:

2 x +3y = -3

3x + 5y = -9

make x the subject:

[tex]2 x +3y = -3[/tex]

[tex]2x = -3 - 3y[/tex]

[tex]x = \frac{-3 - 3y}{2}[/tex] _____equation 1

[tex]3x + 5y = -9[/tex]

[tex]3x = -9-5y[/tex]

[tex]x = \frac{-9-5y}{3}[/tex] ______equation 2

solve them simultaneously:

[tex]\frac{-9-5y}{3} = \frac{-3 - 3y}{2}[/tex]

[tex]2(-9-5y) = 3(-3-3y)[/tex]

[tex]-18-10y = -9 - 9y[/tex]

[tex]-10y + 9y = -9 + 18[/tex]

[tex]-y = 9[/tex]

[tex]y = -9[/tex]

now solve for x:

[tex]2 x +3y = -3[/tex]

[tex]2x + 3(-9) = -3[/tex]

[tex]2x -27 = -3[/tex]

[tex]2x = -3 + 27[/tex]

[tex]2x = 24[/tex]

[tex]x = 12[/tex]

coordinates where they both intersect is (12,-9) at one point so they have one solution

Answer:

x = 12

y = -9

The system has one solution as it has one point of intersection at (12, -9)

Step-by-step explanation:

Equation 1:   [tex]2x + 3y = -3[/tex]

Equation 2:   [tex]3x + 5y = -9[/tex]

Rewrite equation 1 to make [tex]x[/tex] the subject:

       [tex]2x + 3y = -3[/tex]

[tex]\implies 2x = -3 - 3y[/tex]

[tex]\implies x = -\dfrac32 - \dfrac32 y[/tex]

Substitute this into equation 2 and solve for [tex]y[/tex]:

       [tex]3( -\dfrac32 - \dfrac32 y)+5y=-9[/tex]

[tex]\implies -\dfrac92 - \dfrac92 y+5y=-9[/tex]

[tex]\implies -\dfrac92 +\dfrac12 y=-9[/tex]

[tex]\implies \dfrac12 y=-\dfrac92[/tex]

[tex]\implies y=-9[/tex]

Substitute y = -9 into one of the equations to find [tex]x[/tex]:

      [tex]2x + 3(-9) = -3[/tex]

[tex]\implies 2x - 27 = -3[/tex]

[tex]\implies 2x = 24[/tex]

[tex]\implies x=12[/tex]

Answer:

∠ECD = 82°

Step-by-step explanation:

Alternate Interior Angles Theorem : when two parallel lines are cut by a transversal, the alternate interior angles are congruent.  Alternate angles form a Z shape and are sometimes called "Z angles".

Therefore,

∠CDF = ∠GBC = 45°

∠CEF = ∠GAC = 53°

The sum of the interior angles of a triangle is 180°

⇒ ∠ECD + ∠CDF + ∠CEF = 180

⇒ ∠ECD + 45 + 53 = 180

⇒ ∠ECD = 180 - 45 - 53 = 82°

In ∆ABC

[tex]\\ \tt\longrightarrow x+53+45=180[/tex]

[tex]\\ \tt\longrightarrow x+98=180[/tex]

[tex]\\ \tt\longrightarrow x=180-98[/tex]

[tex]\\ \tt\longrightarrow x=82[/tex]

Now

m<ECD and m<ACB are opposite hence equal

Answer:

35.93

Step-by-step explanation:

If the mean of 15 numbers is 41.6, the sum of these numbers must be (15)*(41.6) = 624

We n=know one of these numbers is the 117 that was entered by mistake.  Subtract that out and replace it with the correct number, 17.  In essence we are modifying the number by (-117+17) or -100.

524 is the corrected value.  Divide that by 15 to find the ciorrect mean:

(524)/15 = 34.93

The residual value when the value of x = 4 is -1, the correct option is B.

Given

Melissa collected the data in the table.

The difference between the observed value of the dependent variable (y) and the predicted value (ŷ) is called the residual.

The value of x= 4 then the value of residual is given by;

[tex]\rm Residual=Given - predicted \ value[/tex]

Here, given is 9 and the predicted value is 10 for x =4.

Substitute all the values in the formula;

[tex]\rm Residual=Given - predicted \ value\\\\\rm Residual=9-10\\\\\rm Residual=-1[/tex]

Hence, the residual value when the value of x = 4 is -1.

Answer:

1/5x dogs were on a leash

Step-by-step explanation:

To work through this problem we have to keep in mind that x represents the number of dogs at the park.

1/5 of x dogs are leashed.

Therefore, we can conclude that the answer is 1/5x.

I have no idea if the picture of the dogs was meant to give a clue but hope this helps :)

Answer:

2 mm: 1 m

Step-by-step explanation:

That is, the same soccer field has different lengths in actual and in a map.

These scale and actual lengths must be related, and they are related to each other by what we call the scale ratio.

Scale ratio = dimensions in a drawing : actual dimensions

= 232mm : 116m

(we divide this by 116 to get 2)

= 2mm : 1m

Make all of the +/-2 values into -3,+4

Step-by-step explanation:

This is because the x intercept values for a parabola are where the equation equals zero, by making the equations -3 and +4, the equations will give zero values at -4 and plus 3 when they are set equal to zero, I can specify further if need be.

Answer:

15m

Step-by-step explanation:

to answer this question, we need to use pythagorean theorem. this theory says:

a² + b² = c²

so, let’s work out b.

a² + b² = c²

20² + b² = 25²

20 x 20 = 400. 25 x 25 = 625.

400 + b² = 625.

we want to solve for b, which means to get b in it’s own, so we are going to get rid of the 400 on both sides, leaving just b² on the one side.

625-400=225.

b² = 225

b = √225

b = 15 :)

Answer:

x=12

Step-by-step explanation:

Using the external angle theorem (external angle = sum of interior angles that are NOT adjacent to the external angle you are finding), we can set up an equation...

140=3x+4+8x+4

Start by combining like terms...

140=11x+8

Subtract 8 from both sides

132=11x

Divide both sides by 11

x=12

The slope of these lines is -17/7

The total cost of canvas required to make the tent at the rate of Rs. 15 per square meter is; Rs. 24,997

We are told that the bottom part of the tent house is a square cuboid up to a height of 10 m.

Thereafter, it is a pyramid.

Now, formula for volume of a cuboid is;

V = lwh

V = 20 * 20 * 10

V = 4000 m³

Formula for volume of a pyramid is;

V = lwh/3

V = (20 * 20 * h)/3

V = 400h/3

Total volume is 4800 of the entire tent house. Thus;

4000 + (400h/3) = 4800

400h/3 = 800

h = (800 * 3)/400

h = 6 m

Now, from online calculation, the surface area of the pyramid excluding the base is;

TSA_p = 466.48 m²

Total surface area of cuboid excluding the top is;

S.A = 1200 m²

Total surface area of canvas = 1200 + 466.48 = 1666.48 m²

Since cost per sq.m is Rs. 15 per m², then;

Total cost = 15 * 1666.48

Total Cost = Rs. 24,997

To calculate the slope divide the change in y by the change in x:

(9 - 0) / (6 - 0) = 9/6 = 3/2 cm/s

Answer:

Step-by-step explanation:

You want the values of x and PS for the trapezoid in the figure, given that its perimeter is 228 units.

The trapezoid is shown as an isosceles trapezoid, so PS = RQ. The Triangle RTQ will be repeated on the left side, meaning there is a point T' below point S such that T'P = 4 and T'T = SR = 4x+1.

The perimeter is the sum of side lengths. Working clockwise from the upper left corner this is ...

  perimeter = (4x+1) +(2x -3) +4 +(4x +1) +4 +(2x -3) = 12x +4

Solving for x, we find ...

  12x +4 = 228

  12x = 224

  x = 224/12

  x = 18 2/3

And PS is ...

  PS = RQ = 2x -3 = 2(18 2/3) -3 = 37 1/3 -3

  PS = 34 1/3

Answer:

except when x = 3

Step-by-step explanation:

f(x) = [tex]\frac{1}{x-3}[/tex]

the denominator cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be.

x - 3 = 0 ⇒ x = 3 ← excluded value

f(x) is defined for all real numbers except when x = 3
