Answers
Answer:
Step-by-step explanation:
The function must be factorable.
For example, x^2 + x - 6= 0 factors to (x + 3)(x - 2) = 0 so the roots are -3 and 2.
x^2 + x - 7 = 0 will not factor so you need another method to solve this.

whats the height?
Answers
Answer:
7.5
Step-by-step explanation:
The height of the cylinder is equal to 7.5 meters.
Given that,
An oblique cylinder has a volume of 90π m ^3 and a base area of 12π m^2.
A cylinder is defined as it is geometric shape when a rectangle sheet fold into a circular shape the figure arises looks same as the tube structure.
What is volume?Volume, is defined as the ratio of the mass of object to its density.
The volume of the oblique cylinder = height * base area
90π = 12π * height
height = 7.5 m
Hence, the height of the cylinder is equal to 7.5 meters.

A quadratic in factored form is given as (x + 5) (2x - 3) = 0, what are the solutions of this given equation?
X = and x =
Answers
Answer:
x = -5, x = 1.5
Step-by-step explanation:
If the two expressions multiplied together is 0, that means that one of the expressions would have to equal 0. This gives us two possible answers. Our two equations are now:
x + 5 = 0
2x - 3 = 0
We will first solve the first one!
To isolate x, we subtract 5 from both sides to get:
x = -5
Onto the second one!
We begin to isolate x by adding 3 to both sides.
2x = 3
Now we divide both sides by 2.
x = 3/2 or 1.5

If a triangle has a side length of 5 inches and another side length of 7 inches, which of the
following choices for the third side length will make a triangle?
a. 1 inch
b. 2 inches
c. 6 inches
d. 13 inches
Answers
Answer:
d. 13 inches
Step-by-step explanation:
When we need to solve the side length and length of triangles, we need to remember one thing.
Coming to a right triangle, there are two short sides and one long side, and the two short sides need to add up to something less than the one long side.
Therefore, since we know our two short sides, add them :
7in. + 5in.
= 12in.
Looking at the answers, we can point out that d. is greater than 12 inches, therefore making it the correct answer.

Which system of equations can be used to find the number of 7-inch plates, x, and the
number of 12-inch plates, y, that are in the cabinet?
A
x + y = 140
12x + 7y = 15
B
7x +12y = 140
7x + 12y = 15
cx + y = 15
7x + 12y = 140

Answers
Answer:
x = 1
Step-by-step explanation:
[tex]\sqrt[3]{3x - 2} = 1[/tex] Cube both sides of the equation
3x - 2 = 1
3x = 3
x = 1
Check: [tex]\sqrt[3]{3(1) - 2} = \sqrt[3]{3 - 2} = \sqrt[3]{1} = 1[/tex] Since x = 1 makes the original equation true, then x = 1 is the solution.
The correct solution for the given equation is x = 1.
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given is a cubic equation, [tex]\sqrt[3]{3x-2}[/tex] = 1
Solving for x,
[tex]\sqrt[3]{3x-2}[/tex] = 1
Cubing both the sides,
([tex]\sqrt[3]{3x-2}[/tex])³ = 1
3x - 2 = 1
3x = 3
x = 1
Hence, the correct solution for the given equation is x = 1.

Answer:
Plug the x-values into the equation to get the y values. This will give you coordinates that you can graph a line with.
Step-by-step explanation:
For x = -5: y = -3 - 2 * (-5) = 7, so the coordinates are (-5, 7)
For x = -2: y = -3 - 2 * (-2) = 1, so the coordinates are (-2, 1)
(Etc.)
Then, plot these coordinates and draw a line through them to complete the graph.
