Answer:

y = 42x + 2

Step-by-step explanation:

The equation of a line is expressed as y = mx+b

Slope = y2-y1/x2-x1

Slope = 128 - 2/3-0

Slope m = 126/3

Slope = 42

Since the y intercept is (0, 2), hence b = 2

Get the equation;

Recall that y = mx+b

y = 42x + 2

This gives the required equation

Answer:

6 runners

Step-by-step explanation:

Complete question

A relay race covers 1 1/2 kilometers, and each runner on a team will run 1/4 of a kilometer.  How many runners are needed for a team?

Given that;

1 runner = 1/4 km

If a relay race covers  1 1/2 km, hence;

x runner = 1 1/2 km

Divide both expressions

1/x = (1/4)÷(1 1/2)

1/x = 1/4 ÷ 3/2

1/x = 1/4 * 2/3

1/x = 2/12

Cross multiply

2x = 12

x = 12/2

x = 6

Hence 6 runners are needed for the race

Answer:

6.12 x 10⁵

Step-by-step explanation:

You just multiply 3.4 and 1.8 which gives 6.12

And for the notation you add the exponents 2 and 3 which give 5

Answer:

6.12 × 10^5.

Step-by-step explanation:

3.4 × 10² × 1.8 × 10³

To solve this, we can group.

[tex](3.4 * 1.8) * (10^2 * 10^3) =[/tex]  [tex](6.12) *(10^5).[/tex]

Therefore,[tex](3.4 *1.8)*(10^2*10^3) = 6.12 * 10^5[/tex]

Answer:

x = 5

Step-by-step explanation:

using the Pythagorean theorem:

x² = 13² - 12² = 169 - 144 = 25

x = √25 = 5

Answer:

x = 5.

Step-by-step explanation:

For a right triangle, use the Pythagorean Theorem, a² + b² = c², where a and b are the sides, and c is the hypotenuse.

a² + b² = c²

x²+ 12² = 13²

x² + 144 = 169

Subtract 144 from both sides.

x² = 25

x = 5.

Proof:

a² + b² = c²

5² + 12² = 13²

25 + 144 = 169

169 = 169.

Answer:

4 is the diameter

Step-by-step explanation:

Given:

C = 4π

Formula for circumference:

C = 2πr

Work:

C = 2πr

4π = 2πr

r = (4π)/(2π)

r = 2

Diameter:

d = 2r

d = 2(2)

d = 4

eq^2: 7x=84 divide 84 by 7 which is 12.

therefore x is equal to 12. Then

1) take that 12 you got in equation 2 and substitute in equation 1 which is:

7x-12y=180

7(12)-12y=180

84 -12y=180

-12y=180-84

-12y=96 ............divide both sides with -12

-y=8 (×-1) both sides

y= -8

therefore 7(12)-12(-8)=180

Answer:

[tex]14.1[/tex]

Step-by-step explanation:

Since we have two sides of a triangle and the angle between them, we can use the Law of Cosines.

For any triangle, the Law of Cosines states:

[tex]b^2=a^2+c^2-2ac\cos B[/tex], where [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are all interchangeable.

Substituting given values, we have:

[tex]b^2=9^2+19^2-2(9)(19)\cos 45^{\circ},\\b^2=200.169480834,\\b\approx \boxed{14.1}[/tex]

Answer:

x = ± [tex]\sqrt{\frac{y}{a} }[/tex]

Step-by-step explanation:

Given

y = ax² ( divide both sides by a to isolate x² )

[tex]\frac{y}{a}[/tex] = x² ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{y}{a} }[/tex]

Answer:

x>-2

Step-by-step explanation:

So, lets start by distrubuting the -3 to x:

-3x-4<2

Then lets just start solving. First lets add 4 to both sides to get -3x alone:

-3x<6

Now lets divide -3 from both sides to get x alone:

x<-2

There is one thing we must remember, however.

When dividing a inequality by a negative, the sign is flipped.

So in this case, the < is now >:

x>-2

This basically means a solution is any value greater than -2!

Answer:

[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}[/tex] = 8

Step-by-step explanation:

The given expression is :

[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}[/tex]

We know that,

[tex]\dfrac{1}{x}=x^{-1}[/tex]

So,

[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}=(\dfrac{1}{2^2})^{\dfrac{-3}{2}}\\\\=(2^{-2})^{\dfrac{-3}{2}}\\\\=(2^{-1})^{-3}\\\\=2^3\\\\=8[/tex]

So, the value of the given expression is 8.

[tex]2x - 8 = x + 4[/tex]

Collecting like terms,

[tex]2x - x = 4 + 8[/tex]

Since the signs change when its position changes.

[tex]x = 8 + 4 \\ x = 12[/tex]

Answer:

The value of x would be 12.

Step-by-step explanation:

2x - 8 = x + 4

2x - x = 4 + 8

x = 12

Step-by-step explanation:

Based on the question given :

Total pounds of cheese = 12

These cheese are sliced into 1/4 pounds and 1/2 pounds packages.

What the question requests is the number of 1/2 pounds fraction we can get from the total 12 pounds of cheese.

This means we aren't cutting out 1/4 pounds fraction from this package as the question didn't specify.

Hence, the number of 1/2 pounds fraction obtainable from 12 pounds of cheese I s:

We divide the 12 pounds cheese by 1/2

This gives :

12 ÷ 1/2 ; 12 / 1/2

÷ change to multiplication ond the reciprocal of the denominator is used

12 * 2 /1 = 24 /1

We Obtain 24 1/2-pound cheese

Answer:

Step-by-step explanation:

Use the formula of distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],

Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

1. Distance between A(3, 4) and B(8, 12),

  AB = [tex]\sqrt{(8-3)^2+(12-4)^2}[/tex]

  AB = [tex]\sqrt{25+64}[/tex]

        = [tex]\sqrt{89}[/tex]

        ≈ 9.43

2. Distance between C(-2, 10) and D(3, -2),

   CD = [tex]\sqrt{(3+2)^2+(-2-10)^2}[/tex]

         = [tex]\sqrt{25+144}[/tex]

         = [tex]\sqrt{169}[/tex]

         = 13.00

3. Distance between X(20, 4) and Y(17, 0),

    XY = [tex]\sqrt{(20-17)^2+(4-0)^2}[/tex]

          = [tex]\sqrt{3^2+4^2}[/tex]

          = [tex]\sqrt{25}[/tex]

          = 5.00

4. Distance between E(2, -1) and M(6, 9),

    EM = [tex]\sqrt{(2-6)^2+(-1-9)^2}[/tex]

          = [tex]\sqrt{16+100}[/tex]

          = [tex]\sqrt{116}[/tex]

          = 10.77
