Answer:
yes
Step-by-step explanation:
heres why
Step 1: Add 5 to both sides.
7y−5+5=9+5
7y=14
then ima divide 14 by 7 which equals 2

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

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

Twice the difference of a number and 7 is equal to 3 .
Use the variable y for the unknown number.
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.

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
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
y=-3*0-2

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-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 ≠ -7Here, we see that 13 does not equal -7. ∴ r has no solutions.

y=5x-4y = 5 x − 4
y=-x+2
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

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.
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).
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 :
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.
