Can someone solve this?

Answers

Answer 1

Your answer would be (x,y)=(-17/14,-7)

Answer 2

Answer:

Y=-5.6

x=.9

Step-by-step explanation:

Isolate the x:

6x=11+y

2x=7-3y

multiply top by 3 to get rid of y(3y and -3y cancel each other out)

18x=11

2x=7

put them together:

20x=18

divide by 20

x=0.9

to find y plug in x to the first equation:

y=6(.9)-11

y=5.4-11

y=-5.6

I hope this is right, and that it helps!

Answers

Answer:

For number 2: 8/165

Step-by-step explanation:

The total number of coins = 11 ( 3 + 4 + 4 = 11).

The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).

The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).

The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).

I don't know the other problem, sorry.

Answer:

2) 8/165

3) 4/15

Step-by-step explanation:

2) P(N,D,Q) = 3/11 x 4/10 x 4/9

3) P(M,D) = 4/10 x 6/9

The circumference is basically the radius times 2. So if the radius of that circle is 8, then you would add 8 plus 8, which is 16.

The answer would be 16pi or approximately 50.27 because c=2•pi•r, r=8, so it would be 2•pi•8 which equals 16pi or approximately 50.27

Find the measure of the indicated angle to the nearest degree
A) 18°
C) 48°
B) 42°
D) 26°

Answers

Answer:

The answer is option C

Step-by-step explanation:

To find the indicated angle we use sine

sin ∅ = opposite / hypotenuse

From the question

The opposite is 37

The hypotenuse is 41

So we have

sin ? = 37/41

? = sin-¹ 37/41

? = 64.4805

? = 64° to the nearest degree

In a high school stadium there are 1575 seats. There are two and a half times as many seats in the home section as there are in the visitor section. Which system of equations could be used to determine the number of seats in the home section, h, and the number of seats in the visitor section, v, in the stadium?

Answers

Answer:

h = 1,125

v = 450

Step-by-step explanation:

Total number of seats = 1575

h = number of seats in the home section

v = number of seats in the visitor section

There are two and a half times as many seats in the home section as there are in the visitor section.

h = 2 1/2 * v

h = 2 1/2v

Total = h + v

1575 = 2 1/2v + v

1575 = 3 1/2v

1575 = 7/2v

v = 1575 ÷ 7/2

= 1575 × 2/7

= (1575*2) / 7

= 3150 / 7

= 450

v = 450

h = 2 1/2v

= 5/2*450

= 2250/2

= 1,125

h = 1,125

What is linear inequality?

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

The given inequality can be solved as follows,

4x - 5 ≥ 7

Subtract 7 from both sides to obtain,

4x - 5 - 7 ≥ 0

=> 4x - 12 ≥ 0

=> 4x ≥ 12

=> x ≥ 3

The graph for the given inequality is shown as below,

Hence, the solution for the given inequality is x ≥ 3.

In exercises 27-30, three vertices of DEFG are given. Find the coordinates of the remaining vertices: D(-2,-4), F(0,7), G(1,0)

Answers

Answer:

[tex]E =[/tex] [tex](-3,3)[/tex]

Step-by-step explanation:

Given

Parallelogram: DEFG

[tex]D(x_1,y_1) = (-2,-4)[/tex]

[tex]F(x_3,y_3) = (0,7)[/tex]

[tex]G(x_3,y_4) = (1,0)[/tex]

Required

Find the coordinates of [tex]E(x_2,y_2)[/tex]

To do this, we make use of mid-point formula which is:

[tex]M = (\frac{x_1+x_3}{2},\frac{y_1+y_3}{2})= (\frac{x_2+x_4}{2},\frac{y_2+y_4}{2})[/tex]

This gives:

[tex](\frac{-2+0}{2},\frac{-4+7}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]

[tex](\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]

Multiply through by 2

[tex]2 * (\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})*2[/tex]

[tex](-2,3) = (x_2+1,y_2+0)[/tex]

[tex](-2,3) = (x_2+1,y_2)[/tex]

By comparison:

[tex]-2 = x_2 + 1[/tex] and [tex]3= y_2[/tex]

So, we have:

[tex]-2-1=x_2[/tex] and [tex]3= y_2[/tex]

[tex]-3 = x_2[/tex] and [tex]3 = y_2[/tex]

This gives:

[tex]x_2 = -3[/tex] and [tex]y_2 =3[/tex]

Hence, the 4th coordinate is: [tex](-3,3)[/tex]

Answers

Part A

By evaluating the derivative with respect to t of the height function h(t),
which is h’(t)=-2t+4,

we can find the turning point of the quadratic graph by solving h’(t)=0.

-2t+4=0
t=2

Therefore, we can know that when t=2, Sally’s potato attains its maximum height, which is
-(2^2)+4(2)+5
=9
Given that Sam’s potato has been 10 unit high, Sam’s potato went higher than Sally’s did.

=======================

Part B

Note that the for all t where h(t)>0, the potato is still in the air.
So all we need to do is to solve h(t)>0.

-t^2 + 4t + 5 > 0
t^2 - 4t - 5 < 0
(t + 1)(t - 5) < 0
Therefore we get -1 < t < 5.

But t represents time so it can’t be negative.
So the overall solution is 0 < t < 5.
Therefore the total flying time of Sally’s potato is 5 units.

Because the flying time of Sam’s potato is 3.5 units,
Sally’s potato stayed in the air longer.

Answers

Answer:

19 degrees.

Step-by-step explanation:

First solve the angles in the top triangle:

FHG = 180 - 135 = 45 (angles on a straight line = 180)

FGH = 180 - 105 = 75 (angles on a straight line = 180)

Using these we get HFG = 180 - 45 - 75 = 60 (angles in a triangle = 180)

Then because HFG is directly opposite DFC on the crossed lines, we know they are equal: DFC = 60

FDC = 180 - 119 = 61 (anges on a straight line = 180)

Now if we label ABC (the target angle) as x then we known ACB = 180 - 40 - x.

With this we know FCD = 180 - ACB = 180 - (180 - 40 - x) = 40 + x (angles on a straight line).

Finally using the FDC triangle we have 40 + x + 60 + 61 = 180 so x = 180 - 40 - 60 - 61 = 19 degrees.
