Answer:
Y = 1/4x - 5
Step-by-step explanation:
Slope (m = y2-y1 / x2-x1) is 1/4 and using one point substituting it instead of x and y you get y - intercept of -5.

Explain the steps to solve for g in the equation −1/3g+5=2 .
Answer:
g = 9. I hope that I help my buddy out :)
Answer:
g=9
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
-1/3g=5-5=2-5
-1/3g=-3
Step 2: Multiply both sides by 3/(-1).
(3/-1) x (-1/3g)=(3/-1) x (-3)
ANSWER g=9

A flag is 2 feet by 3 feet. I want to enlarge the flag so that the longest side is 15 feet. How long should the shorter side of new flag be to be proportional to the smaller flag?
Answer:
10 feet
Step-by-step explanation:
Given
Dimension = 2 feet by 3 feet
Required
Determine the length of the short side if the longer side is scaled to 15 feet
Represent the before and after enlargement as a ratio:
Before Enlargement
Ratio = 2 ft : 3ft
After Enlargement
Ratio = x : 15 ft
Where x represents the length of the shorter side
Since they're both proportional, their ratio must be equal.
So, we have:
2 : 3 = x : 15
Convert ratio to fraction
⅔ = x/15
Multiply both sides by 15
15 * ⅔ = 15 * x/15
15 * ⅔ = x
30/3 = x
10 = x
x = 10
Hence, the length of the shorter side must be 10 feet

Answer:
12√24√22√24√2Step-by-step explanation:
The differences of coordinates are ...
E-D = (-2, 0) -(-4, -2) = (-2+4, 0+2) = (2, 2)
The slope is the ratio of the y-difference to the x-difference:
slope of DE = ∆y/∆x = 2/2 = 1
The length is the root of the sum of the squares of those differences:
length of DE = √(2² +2²) = √8 = 2√2
__
Similarly, the slope of CB is found from ...
B -C = (1, -2) -(-3, -6) = (1+3, -2+6) = (4, 4)
slope = 4/4 = 1
And the length is ...
length of CB = √(4² +4²) = 4√2
__
Because the slopes of DE and CB are both 1, DE ║ CB.
DE = 2√2 and CB = 4√2.
Because 2√2 = (1/2)·4√2, DE = 1/2·CB.

“The new coordinates are (3, -2).”
State the error.
Write the rule.
What is the correct answer?
Answer:
(3,2)
Step-by-step explanation: Because -3 and -2 are negative so when you reflect them the opposite of a negative is positive. So the answer is (3,2) HOPE THAT HELPS.

Create an equation for a cubic function in standard form
Answer:
f(x) = 2x³ - 10x² - 34x + 42
Step-by-step explanation:
The standard form of a cubic equation is f(x) = ax³ + bx² + cx + d
Given conditions are:
First: Zeros of the cubic function are - 3, 1, and 7
Second: f(- 2) = 54
a(-3)³ + b(-3)² + c(-3) + d = 0 ⇔ - 27a + 9b - 3c + d = 0 ...... (1)
a + b + c + d = 0 ......... (2)
a(7)³ + b(7)² + c(7) + d = 0 ⇔ 343a + 49b + 7c + d = 0 ....... (3)
a(-2)³ + b(-2)² + c(-2) + d = 54 ⇔ - 8a + 4b - 2c + d = 54 ...... (4)
We have 4 equations with 4 unknown variables.
Use Cramer's rule to solve the system
A = [tex]\left[\begin{array}{cccc}-27&9&-3&1\\1&1&1&1\\343&49&7&1\\-8&2&-2&1\end{array}\right][/tex] = 6,480
[tex]A_{a}[/tex] = [tex]\left[\begin{array}{cccc}0&9&-3&1\\0&1&1&1\\0&49&7&1\\54&2&-2&1\end{array}\right][/tex] = 12,960
[tex]A_{b}[/tex] = [tex]\left[\begin{array}{cccc}-27&0&-3&1\\1&0&1&1\\343&0&7&1\\-8&54&-2&1\end{array}\right][/tex] = - 64,800
[tex]A_{c}[/tex] = [tex]\left[\begin{array}{cccc}-27&9&0&1\\1&1&0&1\\343&49&0&1\\-8&2&54&1\end{array}\right][/tex] = - 220,320
[tex]A_{d}[/tex] = [tex]\left[\begin{array}{cccc}-27&9&-3&0\\1&1&1&0\\343&49&7&0\\-8&2&-2&54\end{array}\right][/tex] = 272,160
a = [tex]\frac{A_{a} }{A}[/tex] = 2
b = [tex]\frac{A_{b} }{A}[/tex] = - 10
c = [tex]\frac{A_{c} }{A}[/tex] = - 34
d = [tex]\frac{A_{d} }{A}[/tex] = 42
f(x) = 2x³ - 10x² - 34x + 42

Venetta and Bill each made a chain of paper clips and measured their lengths Venetta's paper clip chain was 3 feet 5 inches long. Bill's chain was 39 inches long. Who had the long clip chain?
Answer:
Vennetta
Step-by-step explanation:
Length of Venetta's paper clip chain = 3 feets 5 inches
Length of Bill's paper clip chain = 39 inches
Converting both Venetta's paper clip chain length to inches only :
1 foot = 12 inches
3 feets = (12 * 3) = 36 inches
Hence,
Length of Venetta's paper clip chain in inches :
(36 + 5) inches = 41 inches
41 inches > 39 inches .
Hence, Venetta has the long clip chain.
