Twice the difference of a number and 7 is equal to 3 .

Use the variable y for the unknown number.

Answers

Answer:

2(y-7) = 3

Step-by-step explanation:

Twice means multiply by 2.

The difference of a number and 7 means subtract a number/variable and 7.

Is equal to 3 means = 3.

2(y-7) = 3

The equation of a line is y = -3x - 2. What are the slope and the y-intercept of the line? slope = -3 and y-intercept = 2 slope = 3 and y-intercept = -2 slope = 3 and y-intercept = 2 slope = -3 and y-intercept = -2​

Answers

Answer:

slope -3 and y-intercept -2

Step-by-step explanation:

The slope:

the general linear function is y=mx+n where m is the slope

so slope = -3

y intercept is when x=0

Answer:

3 (second option)

Step-by-step explanation:

g(x) is a piecewise function. To find g(3), you have to see which condition the number 3 satisfies.

Out of the options provided, the only condition 3 satisfies is x≥3.

The equation provided for x being greater than or equal to 3 is 6 - x.

Now we can plug in our x value of 3 and solve.

g(3)= 6 - 3

g(3)= 3

y=5x-4y = 5 x − 4

y=-x+2

Answers

Answer:

Y= x+2 " substituting value of y

Step-by-step explanation:

Y=5x-4y = 5x - 4

or, 5x - 4(x+2) = 5x - 4

or, 5x - 4x+ 8 = 5x-4

or, x +8 = 5x - 4

or, 0= 5x - x - 4-8

or, 0= 4x - 12

What is a Polynomial?

Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.

As per the given data:

We are given a table where in each row and each column an expression is written, we have to fill the table correspondingly after finding out the product of each row head and column head

For row with d and column with 2d²:

= d × 2d² = 3d³

For row with d and column with 11d:

= d × 11d = 11d²

For row with d and column with -4:

= d × -4 = -4d

For row with -9 and column with 2d²:

= -9 × 2d² = -18d²

For row with -9 and column with 11d:

= -9 × 11d = -99d

For row with -9 and column with -4:

= -9 × -4 = 36

The tables should be filled in the following order:

3d³   11d²   -4d

-18d²   -99d   36

Hence, The table should be filled in the following order:

3d³   11d²   -4d

-18d²   -99d   36

A pair of tangents to a circle which is inclined to each other at an angle of 60 degree are drawn at ends of two radii. The angle between these radii must be :

Answers

Answer:

The angle between these radii must be 120º.

Step-by-step explanation:

According to Euclidean Geometry, two tangents to a circle are symmetrical to each other and the axis of symmetry passes through the center of the circle and, hence, each tangent is perpendicular to a respective radius. We represent the statement in the diagram included below.

Then, we calculate the angle of the radius with respect to the axis of symmetry by knowing the fact that sum of internal angles within triangle equals 180º. That is to say:

[tex]\theta = 180^{\circ}-90^{\circ}-30^{\circ}[/tex]

[tex]\theta = 60^{\circ}[/tex]

And the angle between these two radii is twice the result.

[tex]\theta' = 2\cdot \theta[/tex]

[tex]\theta' = 120^{\circ}[/tex]

The angle between these radii must be 120º.

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

13 - 2(4r - 5) = -(7 + 8r)

Step 2: Solve for r

Distribute:                              13 - 8r + 10 = -7 - 8rCombine like terms:              -8r + 13 = -7 - 8rAdd 8r on both sides:           13 ≠ -7

Here, we see that 13 does not equal -7. ∴ r has no solutions.

Part A
Which figures have a volume greater than 600 cubic inches?
A. Cylinder #1
B. Cone #1
C. Cylinder #2
D. Cone #2
E. Sphere


Part B
How many times greater is the volume of the Sphere than the volume of
Cone #1? Round your answer to the nearest tenth.

Answers

Answer:

A). Options (C) and (E)

B). 4.8 times

Step-by-step explanation:

Part A

Volume of cylinder (1) = πr²h

                                    = π(6)²(5)

                                    = 565.5 cubic inches

Volume of cone (1) = [tex]\frac{1}{3}\pi (r)^2h[/tex]

                               = [tex]\frac{1}{3}(\pi )(6)^2(5)[/tex]

                               = 188.5 cubic inches

Volume of cylinder (2) = πr²h

                                     = π(6)²(15)

                                     = 1696.5 cubic inches

Volume of cone (2) = [tex]\frac{1}{3}\pi (r)^2h[/tex]

                                = [tex]\frac{1}{3}\pi (6)^2(15)[/tex]

                                = 565.5 cubic inches

Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]

                              = [tex]\frac{4}{3}\pi (6)^{3}[/tex]

                              = 904.8 cubic inches

Figure having volume greater than 600 cubic inches are cylinder (2) and sphere.

Options (C) and (E) are the correct options.

Part (B)

[tex]\frac{\text{Volume of sphere}}{\text{Volume of cone (1)}}[/tex] = [tex]\frac{904.8}{188.5}=4.8[/tex]

Therefore, volume of sphere is 4.8 times the volume of cone (1).
