Answer:

x = 3.5

y = - 4

Step-by-step explanation:

2(4x + 7y = -14)

8x + 14y = -28

  8x + 5y = 8

- (8x + 14y = -28)

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

        - 9y = 36

            y = 36/-9

            y = - 4

   4x + 7y = - 14

4x + 7(- 4) = - 14

     4x -28 = - 14

            4x = 14

              x = 14/4

              x = 3.5

Answer:

Length = 17m

Width = 11m

Step-by-step explanation:

Expression for the area of the rectangle = 6x² + 19x + 15

Factorising the quadratic expression

6x² + 19x + 15 = (6x² + 9x) + (10x + 15) = 3x(2x + 3) +5(2x + 3) = (3x + 5)(2x + 3)

x = 4m

Length = 3x + 5 = 3(4) + 5 = 12 + 5 = 17m

Width = 2x + 3 = 2(4) + 3 = 8 + 3 = 11m

Answer:x=35.6

Step-by-step explanation:

look at the left triangle. I hope you're familiar with SOH, CAH and TOA.

sin 60°=O/(11√7)

so O= (11√7)sin 60°

now look at the triangle on the right.

cos 45=adjacent/x

cos 45=[(11√7)sin60°]/x

therefore, using ur calculator, you'll get x= [(11√7)sin60°]/cos 45

x=35.64407384

Answer:

WRS and VRT are vertical angles

Step-by-step explanation:

Vertical angles are formed by the same lines and share a vertex

WRS and VRT are vertical angles

Answer:

A (First One)

Step-by-step explanation:

Side AC Is Congruent By Side DF

Side CB Is Congruent By Side FE

Side AB Is Congruent By Side DE

(There's no angles shown so it can't be the second option.)

The diagram has lines on the sides, if it we're SAS then the triangle would have an angle.

Answer:

ΔABC≅ΔDEF by SSS Postulate

Step-by-step explanation:

Hi there!

We are given 2 triangles

And we want to prove them congruent

You may notice that AC and FD have the same tick markings, AB and ED have the same tick markings, and CB and FE have the same tick markings

This means that those sides are congruent

In other words,

AC≅FD

AB≅DE

CB≅FE

If we have 3 pairs of congruent sides, that is enough for one concurrency postulate called side-side-side (SSS), which states that if 3 sides of a triangle are congruent to 3 sides in another triangle, then those triangles are congruent

So the triangles are congruent, but we need to put their vertices in the correct order

So if we make the name of the first triangle ABC, then we need to find the corresponding vertices in the second triangle

So let's find those vertices

D is corresponding to A, as they are both in between line segments that have 1 and 2 tick markings on them

E is corresponding to B, as they are both between line segments that have 2 and 3 tick markings on them

And finally, F is corresponding to C, as they are both between line segments that have 1 and 3 tick markings on them

So the name of the second triangle is DEF

ΔABC≅ΔDEF by SSS Posulate

Hope this helps!

Answer:

read explanation

Step-by-step explanation:

since y=2/5x-3 we substitute x=10 in making it y=2/5*10-3

following PAMDAS we do multiplication first so 2/5*10=4.

so y=4-3 and then we subtract and get y=1. Hope this helps:> if you need more explanation message me. If not give this a heart for helping. Good luck.

Answer:

c not all complex are imaginary

but all imaginary are complex

please brainlist

Answer:

C is False

Step-by-step explanation:

A complex number is represented by

[tex]z = a + bi[/tex]

A imaginary number is represented by

[tex]z = bi[/tex]

A complex number could include a real number so it cant be a pure imaginary number so C is False.

Answer: C complete reversal

Step-by-step explanation:

When there is a complete reversal error which is also known as an " error of complete reversal entry", the debit entry is switched with the credit entry. This is one of the more difficult errors to pick up because the Trial balance remains balanced when this happens as the debits and the credits would still be equal.

When rent is received from a tenant. The correct entries are to debit it to cash which is an asset and so will be debited when it increases.

Then credit it to Rent Receivable because this is a revenue account and these are credited when they increase.

The entries were therefore reversed.

Answer:

[tex]f^-^1(f(3.14))=3.14[/tex]

[tex]f(f(-7))=5[/tex]

Step-by-step explanation:

Hi there!

[tex]f^-^1(f(x))=x[/tex]

Therefore,  [tex]f^-^1(f(3.14))=3.14[/tex]

[tex]f(f(-7))[/tex]

The table tells us that f(-7) is equal to -12.

[tex]f(-12)[/tex]

The table also tells us that f(-12) is equal to 5.

Answer:

Step-by-step explanation:

If the mean is 98, then 104 is only standard deviation away. If we are looking for the values less than this, we have the areas under the normal curve of 34%, 34%, 13.5%, 2.35%, .15% which add to 84%, or as a decimal, .84, choice C.

The z-score of the normal distribution P ( x ≤ 104 ) = 0.84

The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.

The Z-score is calculated using the formula:

z = (x - μ)/σ

where z: standard score

x: observed value

μ: mean of the sample

σ: standard deviation of the sample

Given data ,

Let the z-score of the distribution be z

And , the mean be μ = 98

And , the standard deviation be σ = 6

where z = (x - μ)/σ

So , P ( x ≤ 104 ) = [ P ( x - 98/6 ) ≤ 104 - 98 / 6 ) ]

On further simplification , we get

P ( x ≤ 104 ) = P ( x ≤ 1 )

Using a standard normal distribution table or calculator, we can find that the probability of a z-score less than 1 is approximately 0.8413. Therefore, the probability of x being less than 104 is approximately:

P(x < 104) = P(z < 1) ≈ 0.8413

So there is approximately an 84.13% chance that a value selected at random from this normal distribution will be less than 104

Hence , the probability is 0.84
