Answer:
-4y=40
y=-10
x-3(-10)=17
x-30=17
x=17+30
x=47
Step-by-step explanation:
Answer:
x= 5
y= -4
Step-by-step explanation:
x= 17+3y so you substitute what you got for x in so
17 +3y +7y = -23
10y=-40
y=-4 now you put -4 in for y in the first equation
x = 17 + (3 times -4)
x = 17 - 12
x=5

Answer:
a) t = -7
b) f = 12
c) k = -13
Step-by-step explanation:
a) t + 11 = 4
t = -7
b) f = 8+4
f = 12
c) 5 = 18 + k
-13 = k
Answer:
A= -7
B= 12
C= -13
Step-by-step explanation:
This is how I do it
A) Subtract 4 from each side, and when you do that you get 7=-t which makes the answer -7.
B) Add 8 to both sides and you get f=12.
C) Subtract 5 from each side, and when you do that you get -k=13 which makes the answer -13.

what type of function is y=4x^3+2
Answer:
Cubic Function
Step-by-step explanation:
In mathematics, a cubic function is a function of the form f(x)=ax^3+bx^2+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function.

PLEASE HELP
The polynomial is given as f(x) = (x - 5)(x + 1)(4x + 1).
What is a polynomial? What is a mathematical equation? What do you mean by domain and range of a function?In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. An example of a polynomial of a single indeterminate [x] isf(x) = x² − 4x + 7.
A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.Given is a polynomial with zeroes -
x = 5, x = - 1 and x = - 1/4
The given zeroes are -
x = 5(x - 5) = 0
x = - 1(x + 1) = 0
x = - 1/44x = - 1
(4x + 1) = 0
So, we can write the polynomial as -
f(x) = (x - 5)(x + 1)(4x + 1)
Therefore, the polynomial is given as f(x) = (x - 5)(x + 1)(4x + 1).

Which values are solutions to x > 10?
A. x = 0 and x = 20
B. x = -12 and x = 0
C. X = 12 and x = 20
D. X = 11 and x = 5
Answer:
C
Step-by-step explanation:
if you plug the x values into x>10 you'll see that the only set with both numbers greater than ten is C
The solutions to x > 10 are x = 12 and x = 20 shown in option C.
What is linear inequality?Any two numbers can be compared in a linear inequality statement using symbols such as "<" ">," "≤" or "≥" These values could be algebraic, numerical, or a combination of the two.
Consider the expression x > 10
Case A: x = 0 and x = 20As x = 0 less than 10, so, this option is incorrect.
Case B: x = -12 and x = 0Since, both -12 and 0 are less than 10, incorrect option.
Case C: x = 12 and x = 20Both 12 and 20 are greater than 10. Thus, correct option.
Case D: X = 11 and x = 5As, x = 5 is less than 10, incorrect option.
Therefore, the solutions for expression x > 10 are x = 12 and x = 20.

Answer:
$288
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 18%/100 = 0.18 per year,
then, solving our equation
I = 3200 × 0.18 × 0.5 = 288
I = $ 288.00
The simple interest accumulated
on a principal of $ 3,200.00
at a rate of 18% per year
for 0.5 years is $ 288.00.

Answer:
slope m=--3/-2=-3/2 is required slope
Answer:
m = -3, b = -2
Step-by-step explanation:
The equation is written in the form of slope-intercept, where m = slope and b = y-intercept.
The slope is the number before x. For the equation y = -3x - 2, it's -3.
The y-intercept is the constant. For the equation y = -3x - 2, it's -2.
Hence, m = -3, and b = -2.

Answer:
3 tiles will not fit together.
Step-by-step explanation:
Measure of an Interior angle of a polygon = [tex]\frac{(n-2)\times 180}{n}[/tex]
Here, n = number of sides of the polygon
Therefore, measure of the interior angles of a regular hexagon,
A = [tex]\frac{(6-2)\times 180}{6}[/tex]
A = 120°
Similarly, interior angle of the regular pentagon,
B = [tex]\frac{(5-2)\times 180}{5}[/tex]
B = 108°
Now m∠A + m∠B + m∠C = 360°
m∠C = 360° - (120° + 108°)
= 132°
To fit the given three tiles perfectly, interior angle (∠D) of the third Octagonal tile should be 132°.
D = [tex]\frac{(8-2)\times 180}{8}[/tex]
D = 135°
m∠C ≠ m∠D
Therefore, 3 tiles will not fit together.

Answer:
The 8:19 ratio is the bottles of cherry to the total amounts of bottles
Step-by-step explanation:
im not sure what a model would look like but here's one part of the question
The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.
What is ratio?Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that a hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry.
Total number of bottles = 8 + 7 + 4 = 19
Total number of cherry bottles = 8
The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.
Therefore, the ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.
