what is the value of y in the equation y=3x -2 when x=2​

Answer:

77:56:48

77:48

Step-by-step explanation:

If x:y=11:8 and z:y=6:7

then;

x/y = 11/8 and z/y = 6/7

11y = 8x and 6y = 7z

x = 11y/8 anad z = 6y/7

Hence;

x:y:z

= 11y/8:y:6y/7

= 11/8:1:6/7

= 11/8 * 7/6

= 77:56:48

x:z = 11y/8:6y/7

x:z = 11/8:6/7

x:z = 77:48

Answer:

A scale factor exists because any two circles are similar. You can use the radii to determine the scale factor.

Step-by-step explanation:

The ratio between the radii is 31 so the scale factor is 31=3. The circumference of the smaller circle is C=2π(1)=2π.

Answer:

The distance from Durham to Fuquay-Varina is 30 miles.

Step-by-step explanation:

Given that the cities of Raleigh, Durham, and Fuquay-Varina approximate a right triangle, and the distance from Raleigh to Durham is 24 miles, while the distance from Raleigh to Fuquay-Varina is 18 miles, to determine what is the distance from Durham to Fuquay-Varina, the following calculation must be performed, applying the Pythagorean theorem:

18 ^ 2 + 24 ^ 2 = X ^ 2

324 + 576 = X ^ 2

√ 900 = X

30 = X

Therefore, the distance from Durham to Fuquay-Varina is 30 miles.

Answer:

C it has two real solutions

Step-by-step explanation:

If the discriminant of a quadratic equation is positive, it means that the graph intersects the x-axis, and hence produces two real solutions.  

If the discriminant is zero, then the graph is tangential to the x-axis, and there will be two real coincident solutions.  

If the discriminant is negative, then there are two complex solutions.

Answer:

Multiply 180 degrees by (n minus 2)

Step-by-step explanation:

Number of sides in the polygon = n

Polygons have sides 3, 4, 5, 6.....

Polygon with 3 sides is a triangle

Polygon with 4 sides is a quadrilateral

Sum of it's Interior angles = (n-2) × 180°

For a 3 sided polygon

Sum of it's Interior angles = (n-2) × 180°

= (3 - 2) × 180°

= 1 × 180°

= 180°

For a 4 sided polygon

Sum of it's Interior angles = (n-2) × 180°

= (4 - 2) × 180°

= 2 × 180°

= 360°

Multiply 180 degrees by (n minus 2)

Answer:

if 7 men complete the work in 52 days, it means a man will take (52×7=364)days to complete the same piece of work. therefore 13 men will take (364÷13)days which is equal to 28 days.

Answer:

The volume of this cylinder is 502.4 cubic inch

Step-by-step explanation:

For a given Cylinder

Radius (r) = 4 in.

Height (h) = 10 in.

Now,

Volume of Cylinder

V = πr²h

V = 3.14 × (4)² × 10

V = 3.14 × 16 × 10

V = 502.4 cubic inch

Thus, The volume of this cylinder is 502.4 cubic inch

Answer:

y = 7*(2)^x

Step-by-step explanation:

We know that we have a function of the form:

y = a*b^x

Such that a and b are real numbers, and b also needs to be a positive number.

Such that this function passes through the points (3, 56) and (5, 224)

This means that:

56 = a*b^3

224 = a*b^5

So we have a system of two equations with two variables.

To solve this, we can take the quotient of the two equations (such that the second one is on the numerator) then we get:

(224/56) = (a*b^5)/(a*b^3)

4 = (a/a)*(b^5/b^3) = b^(5 - 3) = b^2

4 = b^2

Then we get:

√4 = b = 2

(because b needs to be positive we only care for the positive square root of 4)

The equation is something like:

y = a*(2)^x

Now we can use again the point (3, 56), so:

56 = a*(2)^3 = a*8

56 = a*8

56/8 = a = 7

Then the exponential equation is:

y = 7*(2)^x
