Answer:
y = - 4x + 6Step-by-step explanation:
Starting with the point-slope form of the equation {y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope}:
m = -4
(2, -2) ⇒ x₀ = 2, y₀ = -2
So, the point-slope form of the equation:
y + 2 = -4(x - 2)
Therefore:
y + 2 = - 4x + 8 {subtract 2 from both sides}
y = - 4x + 6 ← the slope-intercept form of the equation

The graph shows the earning from a bake sale per item sold. Which equation represents the earnings from the bake sale?
Answer:
y = 5x
Step-by-step explanation:
Answer:
B, y= 5x
Step-by-step explanation:
If you look closely to the graph on the "bake sale items" side, when they sold 1 item they earned 5$. And when they sold 5 items they earned 25$. Which would mean every item they sold they get 5$ back which would make it B

Bryan spent 14 minutes on the phone while routing 7 phone calls. How many phone cells does Bryan have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone cells
Step-by-step explanation:
We are told that he spent 14 minutes on the phone while routing 7 phone calls.
Now, we want to find the number of phone cells he will route for a total of 16 minutes.
Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell
Therefore, for 16 minutes, number of phone cells will be;
16 minutes ÷ 2 minutes per phone cell = 8 phone cells

Kathy slices through a circular cake. The cake has a diameter of 14 inches. The slice that Kathy made is straight and has a length of 11 inches. Did Kathy cut along a radius, a diameter, or a chord of the circle
Answer: chord
Step-by-step explanation:
A chord is a straight line that's typically drawn from one particular edge of a circle to another.
In this case, the diameter is 14cm while the length of the line drawn is 11cm, therefore the diameter isn't a chord. It's not a radius as well as the diameter divided by 2 gives the radius which should be 7cm.
Therefore, it's a chord.
What is the slope of a line perpendicular to the line whose equation is 2x+12y=-1922x+12y=−192. Fully reduce your answer.
Answer:
The slope of the perpendicular line m =6
Step-by-step explanation:
Step(i):-
Given that the equation of the straight line
2x + 12y =-192
⇒ 12 y = -192 -2x
[tex]y = \frac{-2x}{12}- \frac{192}{12}[/tex]
[tex]y = \frac{-x}{6} - 16[/tex]
y = m x +C
The slope of the given line[tex]m = \frac{-1}{6}[/tex]
Step(ii):-
The slope of the perpendicular line
[tex]\frac{-1}{m}[/tex]
= [tex]\frac{-1}{\frac{-1}{6} }[/tex]
The slope of the perpendicular line m =6

(-6ab)2
Answer:
B. 36a^2b^2
Step-by-step explanation:
1. Apply exponent rule: (-a)^n = a^n, if n is even
(-6ab)^2 = (6ab)^2
(6ab)^2
2. Apply exponent rule: (a × b)^n = a^nb^n
(6ab)^2 = 6^2a^2b^2
6^2a^2b^2
3. 6^2 = 36
36a^2b^2
In other words, your answer is B.
The answer is Option B)

What describes the end behavior of the polynomial function?
Answer:
[tex]x \to +\infty[/tex], [tex]f(x) \to +\infty[/tex] and [tex]x \to -\infty[/tex], [tex]f(x) \to -\infty[/tex].
Step-by-step explanation:
A polynomial is an algebraic function of the form:
[tex]y = \Sigma_{i=0}^{n}c_{i}\cdot x^{i}[/tex] (1)
Where:
[tex]c_{i}[/tex] - i-th Coefficient.
[tex]x^{i}[/tex] - i-th Power.
[tex]n[/tex] - Grade of the polynomial.
[tex]y[/tex] - Dependent variable.
Mathematically speaking, polynomials are unbounded functions, and from graphic we notice that polynomial is of order 3 due to the fact that function pass through the x axis three times, where each point is a root of the polynomial.
Then, we may conclude that:
(i) [tex]\lim_{n \to +\infty} f(x) = N.E.[/tex]
(ii) [tex]\lim_{n \to - \infty} f(x) = N.E.[/tex]
Then, the right answer is: [tex]x \to +\infty[/tex], [tex]f(x) \to +\infty[/tex] and [tex]x \to -\infty[/tex], [tex]f(x) \to -\infty[/tex].

what fraction is equivalent to 4 12?
Answer:
1/3
Step-by-step explanation:
1/3, 2/6, 3/9, 4/12.
are equivalent fractions. Equivalent fraction of a given fraction is got by multiplying or dividing its numerator and denominator by the same whole number.
The given fraction 4/12 is equivalent to 1/3 which means that both fractions represent the same value.
To find a fraction equivalent to 4/12, we need to simplify it by reducing the numerator and denominator to their lowest terms.
In this case, the GCD of 4 and 12 is 4. When we divide both the numerator and denominator by 4, we get:
4/12 = (4 ÷ 4) / (12 ÷ 4)
= 1/3
Therefore, 4/12 is equivalent to 1/3.
This means that both fractions represent the same value, but the fraction 1/3 is in its simplest form, where the numerator and denominator have no common factors other than 1.

What is the y intercept of 60x+55y=660 [with work shown]
Answer:
(11, 0)
Step-by-step explanation:
to find the y intercept, set y to 0.
60x + 55y = 660
60x + 55 * 0 = 660
60x = 660
60x/60 = 660/60
x = 11
y intercept is (11, 0)
Which of the following could NOT be the lengths of the sides of a triangle?
A.5 in, 5 in, 5 in
B. 10 cm, 15 cm, 20 cm
C. 3 in, 4 in, 5 in
D. 8 ft, 15 ft, 5 ft
Given:
Sides of triangles in the options.
To find:
Which could NOT be the lengths of the sides of a triangle.
Solution:
Condition for triangle:
Sum of two smaller sides of a triangle must be greater than the longest side.
In option A,
[tex]5+5=10>5[/tex]
Sides 5 in, 5 in, 5 in are the lengths of the sides of a triangle.
In option B,
[tex]10+15=25>20[/tex]
Sides 10 cm, 15 cm, 20 cm are the lengths of the sides of a triangle.
In option C,
[tex]3+4=7>5[/tex]
Sides 3 in, 4 in, 5 in are the lengths of the sides of a triangle.
In option D,
[tex]8+5=13<15[/tex]
Since, the sum of two smaller sides is less than the longest side, therefore the sides 8 ft, 15 ft, 5 ft are not the lengths of the sides of a triangle.
Therefore, the correct option is D.
