Answer:
(c) y -2 = 6/5(x -1)
Step-by-step explanation:
The equations are all in point-slope form with a slope of 6/5. The points used are (-1, -2), (-2, -1), and (1, 2). It seems point (1, 2) best matches a point on the graphed line. Choice C is the best. (In the attached graph, choice C is the red line.)
_____
Additional comment
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
__
The equation might be easier to see if the point chosen were one at a grid intersection, such as (-4, -4) or (6, 8).

Answer:
x-intercept: -3 y-intercept: 3
Step-by-step explanation:
Substitute 0 for both variables.
-(0)=3
(0)=3
Answer:
x intercept: [tex](-3,0)[/tex] y-intecept: [tex](0,3)[/tex]
Step-by-step explanation:
So their is two ways to do this.
OPTION 1:
Turn the standern form into slope intercept.
[tex]-x+y=3[/tex]
[tex]y=3+x[/tex]
When [tex]y=0, x=-3[/tex]
Therefore, the y-intercept is 3, and the x-intercept is -3
OPTION 2:
Graph the eqaution, and see where it intercepts
Using desmos, you can graph the equation, then see where it intercepts
It intercepts the x-axis at -3, and the y-axis at 3

Write, in slope-intercept-form, the inequality shown in the graph.
Two points which the boundary line intersects are shown.
Answer:
[tex]y \leqslant -x + 1[/tex]
Step-by-step explanation:
First write the equation of the line with either inequality sign, like so:
[tex]y \geqslant -x + 1[/tex]
Then check to see if the equation is true. The easiest way to do this is to plug the coordinates (0,0) into the equation:
[tex]0 \geqslant -0 + 1 \\ 0 \geqslant 1[/tex]
Since 0 > 1 is false, you know that the correct inequality must be:
[tex]y \leqslant -x + 1[/tex]
If you want to check this, plug the coordinates (0,0) into the equation:
[tex]0 \leqslant -0 + 1 \\ 0 \leqslant 1[/tex]
Since 0 < 1 is true, you know this equation is correct.

If f (x) = 7+2x and g(x) =5x -2, find f (7)
Answer:f=103.444
Step-by-step explanation:
took this test and got an A++
The value of the function [tex]f(x)=7+2x[/tex] for [tex]f(7)[/tex] is 21.
The given functions are [tex]f(x)=7+2x[/tex] and [tex]g(x)=5x-2[/tex].
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
To find [tex]f(7)[/tex], substitute [tex]x=7[/tex] in [tex]f(x)=7+2x[/tex], we get
[tex]f(7)=7+2(7)[/tex]
[tex]f(7)=21[/tex]
Therefore, the value of the function [tex]f(x)=7+2x[/tex] for [tex]f(7)[/tex] is 21.

write an equation of the line passing through the point (5,2) that is perpendicular to the line "-x+3y=12"
Answer:
y = -3x + 17
Step-by-step explanation:
first, change the equation into slope-intercept form
add 'x' to each side to get:
3y + x = 12
divide each side by 3 to get:
y = 1/3x + 4
now we need to use a slope that is the opposite reciprocal of 1/3 which would be -3, in conjunction with the point (5,2), by entering these values into the slope-intercept form so we can find the y-intercept ('b') of the new line:
2 = -3(5) + b
2 = -15 + b
17 = b
put slope and y-intercept together to get:
y = -3x + 17

What does it mean by domain and range and how would I use that to fill out the table?
The domain is the set of all allowed x values. In this case, we consider the whole numbers between 0 and 10. So we have x = 0, x = 1, x = 2, ... all the way up to x = 10.
To find the y values, you replace each x with the numbers mentioned and simplify.
For instance, if x = 2, then,
f(x) = 3.50x
f(2) = 3.50*2
f(2) = 7
This tells us that x = 2 packages cost y = 7 dollars.

what is the slope of y-3=-2(x+5)
Answer: slope (m) = -2
Step-by-step explanation:
y-3=-2(x+5)
put it into y=mx+b
use PEMDAS-Parantheses, Exponents, Mult. Div. Add. Sub. for your order of operations.
first, parantheses.
-2(x+5)
-2 times x = -2x
-2 times 5 = -10
your new equation is y-3 = -2x-10
now, to get y by itself, cancel out the -3 by adding a positive 3 to both sides.
you final equation will be y=-2x-7
in the form y=mx+b, m is your slope.
therefore, -2 is your answer, or slope.

(x+3)(x+1)^2(x−4)>0
Answer:
x < -3 or x > 4
Step-by-step explanation:
The product of the factors is 4th-degree, and the leading coefficient is 1 (positive).
The factors tell you the following about the zeros:
x = -3 . . . sign change from + to -
x = -1 . . . graph touches, but no sign change. - on either side of x=-1
x = 4 . . . sign change from - to +
__
The function will be positive for x < -3 and for x > +4.
_____
Additional comments
The value of the function is zero when any of its factors is zero. The value of a factor changes sign when the value of x changes from one side of the 0 to the other. For example, here, we have x+1 as a factor, so x=-1 is a zero. When x = -0.9, the factor is positive (-0.9 +1 = 0.1). When x = -1.1, the factor is negative (-1.1 +1 = -0.1). If this factor were to the first power, it would cause the value of the function to change sign at x=-1.
However, the factor (x+1) has an even power: (x+1)^2. That means when the factor is negative, its square is positive, and when the factor is positive, its square is positive. In short, the factor (x+1)^2 causes the function to be zero at x=-1, but does not make the function change sign there.
The product of all of these factors will result in a polynomial with x^4 as the highest-degree term. That means the function is of even degree. The leading coefficient is 1, so is positive, and the function will generally have a U-shape. The left-most (odd-degree) zero will be where the function changes sign from positive to negative. The right-most (odd-degree) zero will be where the function changes sign from negative to positive. Those zeros are x=-3 and x=+4, respectively. There are no places between these where the function changes sign, so these zeros are the ends of the regions where the function is positive (>0).
Evaluate the expression please.

A coconut cream pie recipe uses 6 ounces of crearn cheese, 12 ounces of condensed milk, and 10 ounces whipped topping In simplest form, how many ounces of cream cheese are there for every ounce of condensed milk?
Answer:
1 oz of cream cheese to every 2 oz of condensed milk
Step-by-step explanation:
We can completely disregard whipped topping because it does not ask for it.
We have 6 ounces of cream cheese to 12 ounces of condense milk. We can write this as a ration:
6:12
6 oz cream cheese:12 oz condensed milk
The question is basically asking to simplify 6:12
Since the greatest commond factor is 6, we can divide both sides by 6 and get:
1:2
Therefore, there is 1 oz of cream cheese to every 2 oz of condensed milk
