Answer:
x = -164/35.
Step-by-step explanation:
x - 8(2x + 3x +2) = -4x +148
x - 16x - 24x - 16 = -4x + 148
x - 16x - 24x + 4x = 148 + 16
-35x = 164
x = -164/35
Identify the quadratic function(s). (Select all that apply). y(y + 4) - y = 6 (3x + 2) + (6x - 1) = 0 4b(b) = 0 3a - 7 = 2(7a - 3)
Answer:
[A] y(y + 4) - y = 6
[C] 4 b (b)=0
Step-by-step explanation:
First let know what is a quadratic functions(s):
A function is called Quadratic if it consist of only one variable, maximum of three terms, and highest degree of the variable in that Polynomial is 2.
Now let's go through the answer choices:
[A]
y *(y+4) - y =6
y² + 4 y - y -6=0
y²+3 y -6=0
Thus, This is Quadratic Function.
[B]
3 x +2 + 6 x -1=0
9 x-1=0
Thus, This is not Quadratic Function
[C]
4 b*(b)=0
4 b²=0
Thus, This is Quadratic Function.
[D]
3 a- 7 =2 * (7 a-3)
3 a - 7=14 a - 6
3 a - 14 a = 7 -6
-11 a =1
Thus, This is not a Quadratic Function.
Hence, [A] and [C] are quadratic functions.

Algebraically, an ordered pair is a solution to a system of two linear inequalities if and only if it __________.
A.
makes both the top and bottom inequalities false
B.
makes the top inequality true and the bottom inequality false
C.
makes the top inequality false and the bottom inequality true
D.
makes both the top and bottom inequalities true
Answer:
D. Makes both the top and bottom inequalities true
Step-by-step explanation:
System of linear inequalities
Consider these two inequalities:
2x+3y > 20
3x-2y > 5
The solution of the system consists of all the ordered pairs (x,y) that satisfy both inequalities. The ordered pair (3,5) makes the first inequality true because
2*3+3*5=21 and it's effectively greater than 20.
But that pair makes the second inequality false, since
3*3-2*5=-1 is not greater than 5.
Thus, the pair (3,5) is not part of the solution.
If we test the pair (6,2), we'll check both inequalities are true, thus (6,2) is part of the solution.
Thus, the correct answer to the question is
D. Makes both the top and bottom inequalities true
a cylinder has a volume of 78 cm what is the volume of a cone with the same radius and height
Answer:
Volume of cylinder V= bh= 78 cm^3, where b is area of base(circle). Then volume of cone = 1/3bh =1/3*78 = 26 cm^3
Thanks!
Mark me brainliest!
Answer:
Volume (cone) = 26 cm³
Step-by-step explanation:
Given :-
Volume (cylinder) = 78 cm³
To Find :-
Volume (cone) with same height and radius
Solving :-
Find the equation for the volume of the cylinder.
πr²h = 78 cm³
But we know the volume of a cone is 1/3 of the volume of a cylinder.
=> Volume (cone) = 1/3 x 78
=> Volume (cone) = 26 cm³

What is the equation of the line that passes through the point (-6,-4) and has a slope of 1/3
Answer:
[tex]y=\frac{1}{3}x-2[/tex]
Step-by-step explanation:
Given the information, we can use the point-slope form to find the equation for the line: [tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y-(-4)=\frac{1}{3}x(x-(-6) )[/tex]
Isolating y and combining like terms gives us [tex]y=\frac{1}{3}x-2[/tex]

what is the value of x?
Answer:
80
Step-by-step explanation:
The sum of the measures of the interior angles of a triangle is 180 degrees, so:
x+(x-15)+(x-45)=180
x+x-15+x-45=180
3x-60=180
3x=240
x=80

Given f (x) = 5x + 1, find f(0).
Answer:
1
Step-by-step explanation:
5(0)+1=1 because 5x0=0 then add the 1
The value of the function f (x) = 5x + 1 at x equal to zero will be 1.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The given function is f (x) = 5x + 1. The value of the function at x equal to 0 will be calculated as below:-
f (x) = 5x + 1
f (0) = 5 x 0 + 1
f (0) = 0 + 1
f (0) = 1
Therefore, the value of the function f (x) = 5x + 1 at x equal to zero will be 1.

12 (2 -2)+32 = (x +6) +2
Answer: x = 24
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
Step 1: Remove parentheses.
12 (2 − 2) + 32 = [tex]x[/tex] + 6 + 2
Step 2: Simplify 2 − 2 to 0.
12 × 0 + 32 = [tex]x[/tex] + 6 + 2
Step 3: Simplify 12 × 0 to 0.
0 + 32 = [tex]x[/tex] + 6 + 2
Step 4: Simplify 0 + 32 to 32.
32 = [tex]x[/tex] + 6 + 2
Step 5: [tex]x[/tex] + 6 + 2 to [tex]x[/tex] + 8.
32 = [tex]x[/tex] + 8
Step 6: Subtract 8 from both sides.
32 − 8 = [tex]x[/tex]
Step 7: Simplify 32 − 8 to 24.
24 = [tex]x[/tex]
Step 8: Switch sides.
[tex]x[/tex] = 24

You have a piece of canvas that you want to paint. You have enough paint to cover
252 square inches. You know you want one side to be 14 inches. How long should
the other side be if you want to use up all the paint?
show your work
Answer:
18 inStep-by-step explanation:
The area = 252 in²
One side = 14 in
The other side = x
The area of a rectangle is a product of 2 sides
14x = 252x = 252/14x = 18 inAnswer:
h = 18 in.Step-by-step explanation:
Area of a rectangular canvas = base x height (A = b*h)
where A = 252 in²
b = 14 in
find: height (h)
solution:
just plugin the values into the formula:
252 = 14 * h
h = 252 / 14
h = 18 in
