Answer:

x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>

y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>

Step-by-step explanation:

Another way to rewrite (5x-3y, 3x-y) = (16, 12),

5x - 3y = 16 -- (1)

3x - y = 12 -- (2)

Rewriting (1), y = -5/3x - 16/3 -- (1)'

Substituting (1)' into (2),

3x + 5/3x + 16/3 = 12

14/3x = 20/3

x = 10 / 7 -- (3)

Substituting (3) into (2),

3(10/7) - y = 12

30/7 - y = 12

-y = 54 / 7

y = - 54/7-- (4)

Therefore,

x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>

y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>

B because all the numbers listed inside this set are equal or less than -5 which is exactly what the question is asking.

Step-by-step explanation:

the answer is in the above image

please give me brainliest

Answer:

Width = w

Length = 4w + 6

Area = 130 in2

Area = W X L = 130

So, w X (4w + 6) = 130

4w2 + 6w = 130  by distributing

-130           -130

4w2 + 6w - 130 = 0

Step-by-step explanation:

Answer:

Area = 6L² - 4L

Step-by-step explanation:

Let length be L

Given Width, w is 4 less than 6 times length :

That is ,

6 times length = 6 L

4 less than 6 times length means = 6L - 4

Therefore Length  =  L

               Width = 6L - 4

Area = Length x Width

       = L x ( 6L - 4)

       = 6L² - 4L

The answer is below

Step-by-step explanation:

The Richter scale measures the magnitude, M, of an earthquake as a function of its intensity, I, and the intensity of a reference earthquake, . Which equation could be used to find the intensity of an earthquake with a Richter scale magnitude of 4.8 in reference to an earthquake with an intensity of 1?

Solution:

The Richter magnitude scale was developed in 1935 by Charles F. Richter. The Richter scale is used to measure the strength of earthquakes.

The magnitude of an earthquake (M) using a Richter scale is given by:

[tex]M=log(\frac{I}{I_o} )\\\\Where\ I\ is\ the\ intensity\ of\ the \ earthquake,I_o\ is \ the\ intensity\ of\\the\ reference\ earthquake.\\\\Given\ that\ M=4.8,I_o=1.\ Hence:\\\\4.8=log(\frac{I}{1} )\\\\4.8=log(I)\\\\I=e^{4.8}\\\\I = 121.5[/tex]

Answer

MULTIPLY 2.2 & 5.5

Step-by-step explanation:

Answer:

Option D.

Step-by-step explanation:

Remember the Pythagorean theorem.

For a triangle rectangle of catheti A and B, and hypotenuse H, we have:

A^2 + B^2 = H^2

Now, also remember that for a square of sidelength L the area is:

area = L^2

First, you can see that square 1 has a side length equal to one of the catheti, and the same for square 2. While square 3 has a side lenght equal to the hypotenuse of the triangle.

If we define:

A = length of the smaller cathetus

then the area of square 1 is:

A^2

B = length of the larger cathetus.

The area of square 2 is then:

B^2

H as the length of the hypotenuse:

The area of square 3 is:

H^2

And by Pythagorean theorem we know that:

A^2 + B^2 = H^2

We can replace these by:

area of square 1 + area of square 2 = area of square 3.

Then the correct option is D.

Hope this helps u !!

Answer:

0.43 seconds

Step-by-step explanation:

Given Data

Initial height= 4feet

initial velocity u= 30ft per second

Final height = 17 feet

The distance travelled is the

Final-initial height

=17-4

=13ft

Hence the time taken is calculated using the expression below

Speed= distance/time

30=13/t

t= 13/30

t= 0.43 seconds

Hence the time taken is 0.43 seconds

Answer:

Step-by-step explanation:

Perimeter of LMK = 14 + 11 + 17

Perimeter of LMK = 42

Perimeter GHJ/ Perimeter LMK = 5/6

Perimeter GHJ / 42 = 5/ 6                      Cross Multiply

6*Perimeter GHJ = 42 * 5

6*Perimeter GHJ = 210                           Divide by 6

Perimeter GHJ = 210/6

Perimeter GHJ = 35

code = 56

Step-by-step explanation:

E = GCF(22,30) = 2

F = LCM(3,8) = 24

Given

3 * (7+10) = G +30 => 51 = G + 30 => G = 21

5 * (3+H) = 15 + 45 => 3+H = (60/5)  = 12 => H = 12 - 3 = 9

Sum E + F + G + H = 2 + 24 + 21 + 9 = 56

Answer:

x = log 2 / log 3

x=0.63092

Step-by-step explanation:

3^×=2

Take the log of each side

log 3^×= log2

We know that log a^b = b log a

x log 3 = log 2

Divide each side by log 3

x = log 2 / log 3

x=0.63092

Answer:

x ≈ 0.63093

Step-by-step explanation:

[tex] \small \sf \: 3 {}^{x} = 2[/tex]

Take the log of both side

[tex] \small \sf \: log 3 {}^{x} = log 2[/tex]

Use log a( a ^ x ) = x to simplify the equation

x log 3 = log 2

Divide each side by log 3

x = log 2 / log 3

x ≈ 0.63093

Answer:

This is the answer48 cm²

Answer:

A = 44 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

We require to find the missing segment of b₁

Using the tangent ratio in the right triangle

tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{4}{adjacent}[/tex] = 1 , so

adjacent = 4

Then

b₁ = 4 + 8 + 2 = 14 , b₂ = 8 and h = 4 , then

A = [tex]\frac{1}{2}[/tex] × 4 × (14 + 8) = 2 × 22 = 44 cm²

Answer:

44

Step-by-step explanation:

substitute the 7 into the equation for x

f(x) = [tex]x^{2}[/tex] - 5

f(7)  = [tex]7^{2}[/tex] - 5

f(7) = 49 - 5

f(7) = 44

Answer:

f(7) = 44

Step-by-step explanation:

To evaluate the function f(x)=x^2-5 at x = 7, replace each instance of 'x' in this function by 7:

f(7) = 7^2 - 5 = 49 - 5 = 44

So:  f(7) = 44

Answer:

  (a) The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept

Step-by-step explanation:

If we take the "steepness" of the slope to be the absolute value of the slope, then the line y=-10x +6 has a slope with a steepness of 10.

The line y -36 - 8(x -4) has a slope with a steepness of 8, so the first line is steeper.

The line y=-10x+6 has a y-intercept of 6. The line y-36 =8(x -4) has a y-intercept of 4, so the first line has a higher y-intercept.

The appropriate description of the two lines is ...

The diagonal is 6.7082 ≈ 6.71

Step-by-step explanation:

Let the diagonal be x :

To find the diagonal of a 3 by 6 rectangle

We can use the Pythagorean Theorem:

[tex]x^{2} = 3^{2} + 6^{2}[/tex]

⇒ [tex]x^{2} = 9 +36[/tex]

⇒ [tex]x^{2} = 45[/tex]

⇒ [tex]x=\sqrt{45}[/tex]

∴ [tex]x =6.7082[/tex] ≈ [tex]6.71[/tex] (corrected to 2 d.p.)

Answer and Step-by-step explanation:

We're given an isosceles triangle, because it says the two side are congruent. That means the base pairs are congruent as well, meaning the other angle (not x) is 75.

We know that the sum of a triangle's angles is 180, so if we subtract the known angles, we can find x.

180 - 75 - 75 = x

30 = x

So, x = 30.

#teamtrees #PAW (Plant And Water)

We know that a triangles full degree is 180 and we can see that this triangle is symmetrical. So first you add 75 to 75 and get 150, then you subtract 150 from 180 and get 30.

x=30
