April wrote two equations to represent this system of equations. She wrote: y = 5x +
I and y = 14x - 10. Do you agree or disagree with April?

Note: Steps of student are not given. So, the proper steps of the solution are provided below.

Given:

The inequality is

[tex]-5v>55[/tex]

To find:

Where the student made any errors?

Solution:

We have,

[tex]-5v>55[/tex]

On dividing both sides -5 change the sign of equality because -5 is a negative number.

[tex]\dfrac{-5v}{-5}<\dfrac{55}{-5}[/tex]

[tex]v<-11[/tex]

Therefore, the solution of given inequality is [tex]v<-11[/tex].

Answer:

1. A=πr2=π·4.62≈66.4761

A≈66.48

2. A=πr2=π·22≈12.56637

A≈12.57

please mark as brainiest

Answer:

1. 66.48

2. 12.57

Step-by-step explanation:

Formula is A = ㅠr^2

The radius is that half line :))

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {c}^{2} - {b}^{2} = {a}^{2} [/tex]

[tex] {8}^{2} - {6}^{2} = {28}^{2} [/tex]

[tex] \sqrt{28} [/tex]

Answer:

[tex]\boxed{\sf{a=\sqrt{28} }}[/tex]

Pythagorean theorems can be applied to solve this problem.

Pythagorean theorem:

[tex]\rightarrow \sf{a^2+b^2=c^2}[/tex]

⇒ c²-b²=a²

8²-6²=28²

Solve.

PEMDAS stands for:

[tex]\sf{8^2-6^2}[/tex]

Solve by exponents from left to right numbers.

[tex]\sf{8^2=8*8=64}[/tex]

[tex]\sf{6^2=36}[/tex]

Then, subtract.

[tex]\sf{64-36=\boxed{\sf{28}}[/tex]

a=√28

Therefore, the correct answer is a=√28.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

See proof below

Step-by-step explanation:

Given the equation, we are to prove that it is true

(cosec a + 1)*(1 - sin a)= cos a* cot a

From LHS

(cosec a + 1)*(1 - sin a)=

Expand

cosec a - cosecasina + 1 - sina

Since cosec a = 1/sina

1/sina - (1/sina)sina + 1 - sina

1/sina - 1 + 1 - sina

1/sin a - sina

Find the LCM

1-(sin^2a)/sina

cos^2a/sina

cosa * cosa/sina

cos a * cot a (which gives the RHS)

Answer:

R=34

Step-by-step explanation:

As, pythoreon therom states = a2 + b2= c2

a= 16, 16^2 = 256

b= 30, 30^2 = 900

c2= 900+256

c2 = 1,156

c= 34

So, 16^2 + 30^2 = 34^2

Answer:

[tex]6\pi[/tex] or [tex]18.84[/tex] units

Step-by-step explanation:

The circumference of a circle can be found using the formula [tex]C=2\pi r[/tex], where [tex]C[/tex] is the circle's circumference and [tex]r[/tex] is the circle's radius. We know that [tex]r=3[/tex] and that we are solving for [tex]C[/tex]. Therefore:

[tex]C=2\pi r\\C=2*\pi *3\\C=6\pi[/tex]

Since [tex]\pi[/tex] is approximately [tex]3.14[/tex], [tex]6\pi =6*3.14=18.84[/tex] units. Hope this helps!

Answer:

[tex]Volume = 1440m^3[/tex]

Step-by-step explanation:

Given

Missing dimensions:

[tex]Length = 15m[/tex]

[tex]Width = 8m[/tex]

[tex]Height = 12m[/tex]

Required

Determine the volume

Volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

This gives:

[tex]Volume = 15m * 8m * 12m[/tex]

[tex]Volume = 1440m^3[/tex]

Answer:

y=−3x+4

Step-by-step explanation:

Step 1: Flip the equation.

−6x+8=2y

Step 2: Add -8 to both sides.

−6x+8+−8=2y+−8

−6x=2y−8

Step 3: Divide both sides by -6.

−6x −/6 = 2y−8 /−6

Answer:

no

Step-by-step explanation:

you take 7/5 and turn it into an improper fraction

you then have 1 2/5

1 2/5 is smaller then 11

Answer:

Step-by-step explanation:

-7y = -4x + 9

7y = 4x - 9

y = 4/7x - 9/7

perp. -7/4

y - 3 = -7/4(x - 4)

y - 3 = -7/4x + 7

y = -7/4x + 10

Step-by-step explanation:

6 = 3(-1) +9 yes this is true

5(-1) +6 = 1 Yes this is true

so yes it's a solution because it works in both equations.
