Please Helpppppp!!!!! What is the value of x.

Answer:

[tex]x=2.\ y=1[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ the\ following\ pair\ of\ equations:\\5x+7y=17\\7x+5y=19\\Now,\\As\ the\ co-efficients\ of\ none\ of\ the\ algebraic\ terms\ match,\\We\ can\ take\ the\ LCM\ of\ their\ co-efficients;\\As\ the\ co-efficients\ of\ the\ x-terms\ are\ 5,7\ respectively;\\Their\ LCM\ is\ 35.[/tex]

[tex]Hence,\\7(5x+7y)=7(17)\\-5(7x+5y)=-5(19)\\Hence,\\35x+49y=119\\-35x-25y=-95\\Hence,\\Adding\ the\ two\ equations\ we\ have:\\(35x+49y)+(-35x-25y)=(119)+(-95)\\(35x-35x)+(49y-25y)=119-95\\24y=24\\y=\frac{24}{24}=1[/tex]

[tex]Now,\\Lets\ consider\ the\ First\ Equation:\\5x+7y=17\\Substituting\ y=1,\\5x+7*1=17\\5x+7=17\\5x=17-7\\5x=10\\x=\frac{10}{5}=2\\\\Together,\\x=2.\ y=1[/tex]

Answer:

vertical angels?

Step-by-step explanation:

i hope yan yong answer pero di ko sure

Answer:

Angle 1: 115

Angle 2: 65

Angle 3: 115

Angle 4: 65

Angle 5: 115

Angle 6: 65

Angle 7: 115

Step-by-step explanation:

Find the value of angle 2 by applying the vertical angles theorem (65)

Find the value of angle 1 by applying the supplementary angles theorem from the original angle (180 - 65 = 115)

Find the value of angle 3 by applying the vertical angles theorem from angle 1 (115)

Angles 4, 5, 6, and 7 are on a line parallel to the orginal line, cut by the same transversal, so they have the same values, according to the same side interior/exterior angles theorems.

QR is NOT greater than ST

The image shows that QR = 9 and ST = 10.

Ten's obvi the bigger number so insted of QR > ST it should be QR < ST.

Answer:

Area of pathway = 10.375 unit²

Step-by-step explanation:

Given - Peter has built a gazebo, whose shape is a regular heptagon, with

             a side length of 1 unit. He has also built a pathway around the

             gazebo, of constant width 1 unit, as shown below.

To find -  Find the area of the pathway.

Proof -

Central angle = [tex]\frac{360}{7}[/tex] = 51.43°

Now,

Central angle / 2 = [tex]\frac{360}{14}[/tex] = 25.71°

And

height = [tex]\frac{1}{2}.\frac{1}{tan25.41}[/tex] = 1.038

Now,

Inner area of gazebo = 7·[tex]\frac{1}{2}[/tex]·1·(1.038) = 3.634 unit²

Outer area of gazebo = ([tex]\frac{2.038}{1.038}[/tex])²·(3.364) = 14.009 unit²

∴ we get

Area of pathway = Outer area - Inner area

                            = 14.009 - 3.634

                            = 10.375 unit²

⇒Area of pathway = 10.375 unit²

Answer:

yes , keiko is correct.

sin^(-1)x = -sin^1

Answer:

Keiko is wrong

Step-by-step explanation:

Keiko is incorrect

When n is positive, 1^n will always be 1

but........ (-1)^n will not always be -1

This is because there are parenthesis around -1

So n is even, then it will be 1 not -1

For example, n = 4

You will do -1 * -1 * -1 * -1 which is 1 not -1

but if n = 3

You will do -1 * -1 * -1 which is -1

Therefore, the second statement is incorrect resulting in Keiko being wrong

SAMPLE RESPONSE

Step-by-step explanation:

Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

Answer: BC/BF & M<C

Step-by-step explanation:

Answer:

y = 4x - 3

Step-by-step explanation:

The equation for a line is y = mx +c

We need to find m which is the gradient:

To do this pick any two coordinates on the line:

(1, 1) and (2, 5)

Next divide the difference of the y coordinates by the difference of the x coordinates:

5 - 1 / 2 - 1

= 4/1 = 4

so our gradient is 4

We'd write that as y = 4x + c

Next we need to find c which is the y-intercept

To do this just simply look for where the line crosses the y-axis

This is -3

So we'd write that as y = 4x - 3

Hope this helps :)

Answer:

Double - 7 5/6

Explantion: 2 1/4 times 2 equal 4 1/2 for the pancake mix

1 2/3 times 2 equal 3 1/3 for the milk

So.....4 1/2 plus 3 1/3 equals 7 5/6

Triple- 11 3/4

Explantion: 2 1/4 times 3 equals 6 3/4 for the pancake mix

1 2/3 times 3 for the milk equals 5

So.... 5 plus 6 3/4 equal 11 3/4

Hope it help :)
