Solve the following equation for X. X=
-2x – 3.2 – 15 = 20
Answer:
x = -7
Step-by-step explanation:
-2x - 3x = -5x
so then its -5x - 15
you then add 15 to both sides which gives you -5x = 35
divide -5 from each side to get the answer
-7 = x
Step-by-step explanation:
-2x - 3x -15 = 20
-5x = 20 + 15
-5x = 35
x = 35/-5
x = -7
What is the slope of the line -3y = 12x + 6?
Answer:
-4
Step-by-step explanation:
Let us rearrange this equation by dividing both sides by (-3):
y=-4x-2
And since the equation of a line is y=mx+b, where slope=m,
then the slope of our line is -4
I hope this helps! :)
Slope of the line -3y = 12x + 6 is -4.
What is slope intercept - form of line?The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as:
y = mx + b.
Given,
Equation of the straight line
-3y = 12x + 6
Dividing by -3 on both side
y = 12x/-3 + 6/-3
y = - 4x - 2
Comparing the above equation with slope - intercept form equation of line
y = mx + b
where m is slope and b is vertical intercept.
Slope of the given line
m = -4
Hence, - 4 is the slope of the line -3y = 12x + 6 .

Michael has a bag with 38 coins in his backpack consisting of nickels, n, and quarters,q. If he has a total of $4.50, how many nickels, n, does he have?
Answer:
25 Nickles
Step-by-step explanation:
n + q = 38
0.05n + 0.25q = 4.50
n + q = 38
q = 38 - n
0.05n + 0.25q = 4.50
0.05n + 0.25(38 - n) = 4.50
0.05n + 9.5 - 0.25n = 4.50
-0.2n + 9.5 = 4.50
-0.2n = 4.50 - 9.50
-0.2n = -5
-0.2n/0.2 = -5/0.2
-n = -25
-n/-1 = -25
n = 25

A cube root function will (sometime/always/never) have an x-intercept and (never/sometimes/always) have a y-intercept. For the parent cube root function, (only the y-intercept is/only the x-intercept is/both intercepts are) located at (0,0)
Answer:
Always, always, both intercepts
Step-by-step explanation:
A cube root function will always have an x-intercept and always have a y-intercept. For the parent cube root function, both intercepts are located at (0,0).
A cube root function, represented as f(x) = ∛x, will always have an x-intercept and always have a y-intercept.
An x-intercept is a point where the graph of the function crosses the x-axis, and a y-intercept is a point where the graph crosses the y-axis.
For the cube root function, the x-intercept occurs when the input value x is equal to 0. When x is 0, f(x) = ∛0 = 0, which means the function crosses the x-axis at (0, 0).
Similarly, for the cube root function, the y-intercept also occurs at the point (0, 0). When x is 0, f(x) = ∛0 = 0.
so the function also intersects the y-axis at (0, 0).

6. sec0= 20
0= ____
Answer:
tan theta = -1
we know tan = opposite/ adjacent
So opposite/adjacent = -1
Multiply by adjacent on each side
opposite = - adjacent
We also know from pythagorean theorem that
opposite ^2 + adjacent ^2 = hypotenuse ^2
Substituting in for adjacent
opposite ^2 + (-opposite ) ^2 = hypotenuse ^2
opposite ^2 + opposite ^2 = hypotenuse ^2
2 opposite ^2 = hypotenuse ^2
Taking the square root on each side
sqrt(2 opposite ^2) = sqrt(hypotenuse ^2)
sqrt(2) opposite = hypotenuse
We are now set to find the sec
sec theta = hypotenuse / adjacent
= sqrt(2) opposite/ adjacent
Replace the opposite = -adjacent
= sqrt(2) (-adjacent)/adjacent)
= -sqrt(2)

Whats the slope and y-intercept of y=-3x+4?
Answer:
slope= -3. y intercept is 4
Step-by-step explanation:
the x value is slope and the y value is y intercept.
REMEMBER THIS!!! ITS SUPPPER IMPORTANT
Answer:
[tex]\boxed {\sf m= -3}}[/tex]
[tex]\boxed {\sf b= 4}[/tex]
Step-by-step explanation:
The equation of the line is in slope intercept form or:
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Essentially:
The coefficient to x, or number being multiplied is the slope The number added or subtracted from the x term is the y-interceptThe line given is:
[tex]y= -3x+4[/tex]
-3 is the coefficient of x and 4 is being added to -3x.
The slope (m) is -3 and the y-intercept (b) is 4.

What is the standard form of the polynomial
7x - 125 - 6x4 + 14x2
Answer:
Step-by-step explanation:
Writing the polynomial according to the decreasing value of the exponents, the polynomial in standard form is given by:
[tex]p(x) = -6x^4 + 14x^2 + 7x - 125[/tex]
In a standard form polynomial, the terms with the highest exponents always come first.
In this problem, the exponents are, in order, 1, 0, 4 and 2. Thus, first should come the term with exponent 4, then the term with exponent 2, then exponent 1 and finally the term with exponent 0. Thus, the polynomial in standard form is given by:
[tex]p(x) = -6x^4 + 14x^2 + 7x - 125[/tex]
