Answer:

Y= -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(−5y+2)=21

(3)(−5y)+(3)(2)=21(Distribute)

−15y+6=21

Step 2: Subtract 6 from both sides.

−15y+6−6=21−6

−15y=15

Step 3: Divide both sides by -15.

−15y −15 = 15 −15

Y= -1

Answer:

Step-by-step explanation:

1)expand out the bracket

-15y+6=21

2) get the y to one side

6=21+15y

3) solve

15=15y

1=y

(08.01) Two lines, A and B, are represented by the following equations: Line A: 3x + 3y = 12 Line B: x + y = 4 Which statement i

UkoKoshka [18]

Answer: There are infinitely many solutions.

Step-by-step explanation:

Given, Two lines, A and B, are represented by the following equations:

Line A: 3x + 3y = 12

Line B: x + y = 4

By comparing to the equations $a_1x+b_1x=c_1$ and $a_2x+b_2x=c_2$ respectively , we have

$a_1=3,\ b_1=3\ \ \&\ c_1=12\\\\a_2=1,\ b_2=1\ \ \&\ c_2=4$

Now , $\dfrac{a_1}{a_2}=\dfrac{3}{1},\ \dfrac{b_1}{b_2}=\dfrac{3}{1},\ \&\ \dfrac{c_1}{c_2}=\dfrac{12}{4}=\dfrac{3}{1}$

i.e. $\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$

It implies the gives lines are co-incident (linearly dependent).

That means it has infinitely many solutions.

So, the correct answer is "There are infinitely many solutions.".

the ball is 150g heavy and it is dropped from 300m, what is the velocity of the ball just before it touches the ground

boyakko [2]

Answer:

77.5 m/s

Step-by-step explanation:

Once the ball is dropped from the height, it converts all its potential energy into kinetic energy:

$P. E = K.E\\mgh = \frac{1}{2}mv^2$

Using this equation, and the data we have to find the velocity of the ball:

$mass = 150 \ g \\gravity = 10 \ m/s^2\\height = 300 m$

$P.E = mgh\\150 \times 10 \times 300 = \frac{1}{2} \times 150 \times v^2\\\\150 \times 10 \times 300 = 75 \times v^2\\\\v^ 2 = \frac{150 \times 10 \times 300 }{75}\\\\v^2 = 6000\\\\v = \sqrt {6000}\\\\v = 77. 5 \ ms^{-1}$

What is 96\3 as a decimal please help thanks

spayn [35]

3 goes into 96 32 times, so 96/3=32. There is no decimal (unless you insist on including one, then it'd be 32.0) because 3 goes into 96 perfectly.
