Answer:
64 - 5y (exponent of 2)
————-———————–
y (y - 1 )
Step-by-step explanation:
Sorry the set up is weird
Please give brainliest
Answer: y^3 - 6y^2 + 5y
Step-by-step explanation: You start by rewriting the expression y^3- 5y^2/y +(y-1)
Then you factor out y(y^2-5y)/y *(y-1)
Then you reduce the fraction which cancels the 2 y’s out (y^2-5y)(y-1)
Then you multiple the 2 parentheses which equals y^3-y^2-5y^2+5y
Then you simply the answer you got which comes out to y^3-6y^2+5y
Hope this helped!

7x= -56
Im stumped plz help ;-;
Answer: x= -8
Step-by-step explanation: 7x=-56. The goal is to find just 1x. To do this, you need to divide both sides by 7. So 7x divided by 7 is x, and -56 divided by 7 is -8. So x= -8.

The data is given as follow. xi 2 6 9 13 20 yi 7 18 9 26 23 The estimated regression equation for these data is = 7.6 + .9x. Compute SSE, SST, and SSR (to 1 decimal). SSE SST SSR What percentage of the total sum of squares can be accounted for by the estimated regression equation (to 1 decimal)? % What is the value of the sample correlation coefficient (to 3 decimals)? Check My Work
Answer:
SSE = 127.3
SST= 281.2
SSR = 153.9
R² = 0.5473
% = 54.73%
r= +0.7398
Step-by-step explanation:
xi yi Y^ (Yi-Y^)² (Yi-Y`)²
2 7 7.6 + 0.9(2) (7-9.4)² (7-16.6)²
= 9.4 = 5.76 92.16
6 18 7.6 + 0.9(6) (18-13)² (18-16.6)²
= 13 =25 1.96
9 9 7.6 + 0.9(9) (9-15.7)² (18-16.6)²
= 15.7 =44.89 57.76
13 26 7.6 + 0.9(13) (26-19.3)² (18-16.6)²
= 19.3 = 44.89 88.36
20 23 7.6 + 0.9(20) (23-25.6)² (18-16.6)²
= 25.6 = 6.76 40.96
∑50 83 83 127.3 281.2
Y~= ∑yi/n= 83/5= 16.6
SSE = ∑ (Yi-Y^)² = 127.3
SST= ∑(Yi-Y`)²=281.2
SST = SSR + SSE
SSR = SST- SSE
= 281.2- 127.3= 153.9
Co -efficient of determination= R² = SSR/ SST= 153.9/ 281.2= 0.5473
The regression equation is explained by 54.73 % of the total sum of squares.
The linear correlation coefficient is the square root of the co -efficient of determination
r= ±√r²= √0.5473= +0.7398
We only consider the positive value for the linear correlation coefficient to be positive.

the given points. (3,1) and (-5,2). *
Answer: Y-1=-1/8(X-3)
Step-by-step explanation:
Point slope form is Y-y1=m(x-x1)
the slope here is 2-1/-5-3 = 1-/8
so its Y-1=-1/8(X-3)

Simple Inequalities:

Which compound inequality and graph match the given simple inequalities?
Xs6 OR > 9
Answer:
In choice A, the compound inequality x ≤ 6 OR x > 9 and the graph match the given simple inequalities
Step-by-step explanation:
In the compound inequality
If the sign of inequality is >, then the arrow represented it pointed to the rightIf the sign of inequality is <, then the arrow represented it pointed to the leftIf the sign of inequality is ≥ or ≤, then the end of the arrow is a bold circleIf the sign of inequality is > or <, then the end of the arrow is an empty circleLet us solve the question
∵ x ≤ 6
∴ The arrow represents it is starting at 6 with a bold circle and
pointed to the left side
∵ x > 9
∴ The arrow represents it is starting at 9 with an empty circle and
pointed to the right side
→ Look at the graphs to find the answer that represents the information
above
In choice A
∵ an arrow with a bold end started from 6 and pointed to the left
∵ an arrow with an empty end started from 9 and pointed to the right
∴ x ≤ 6 OR x > 9 and the graph match the given simple inequalities

find the equation of a line parallel to y = 3x - 6, passing through the point (-6, -7).
y = 3x + 11
y = 3x - 11
y = 3x - 7
y = -1/3x - 9
Parallel lines have the same a slope. Therefore if
k: y = 3x - 6 → slope = 3
and l: y = mx + b
l || k ⇔ m = 3
l: y = 3x + b
We have the point (-6, -7). Put the coordinates to the equation:
-7 = 3(-6) + b
-7 = -18 + b add 18 to both sides
11 = b → b = 11
Answer: y = 3x + 11

(1) Today, the temperature in New York is -1 degree and is expected to rise 3 degrees per day. It's 6
degrees in Alaska and expected to fall 1 degree every 2 days.
Answer:
New York: m=3, b=-1, y=3x-1
Alaska: m=-1/2, b=6, y=-1/2x+6
2 days; 5 degrees
Step-by-step explanation:
In each case, m is the rate of change, the number of degrees per day that the temperature is changing. 1 degree per 2 days is 1/2 degree per day.
In each case, b is the given initial temperature.
The equation is y = mx + b, for the values of m and b that you fill in.
New York
m = 3, b = -1, equation: y = 3x -1
Alaska
m = -1/2, b = 6, equation: y = -1/2x +6
__
The graphs can be plotted by plotting the initial point on the y-axis, then finding another point based on the slope.
For New York, another point will be 1 unit right and 3 units up, at (1, 2).
For Alaska, another point will be 2 units right a 1 unit down, at (2, 5).
The lines intersect at the point (2, 5) corresponding to 2 days, 5 degrees.

Jada is buying 4 stamps that cost $0.49 each. How can rounding be used to estimate the total cost of the stamps?
Since each stamp is about $0.50, the total cost is approximately 4 + 0.5 = $4.50.
Since she is buying about 10 stamps, the total cost is approximately 10 × 0.49 = $4.90.
Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.
Since she is buying about 10 stamps, the total cost is approximately 10 + 0.49 = $10.49.
The answer of the given question based on the word problem of multiplication is , option (c) Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.
What is Total cost?Total cost refers to the complete amount of money required to purchase or produce a given quantity of goods or services. It includes all the expenses involved in the production or purchase of the product or service, like materials, labor, and overhead costs, as well as any other additional expenses like taxes or shipping fees. Total cost is an important concept in economics and accounting as it helps businesses and individuals to determine the profitability of a product or service and make informed decisions about pricing and production.
The answer is: "Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00."
Rounding can be used to estimate the total cost of the stamps by approximating the cost of each stamp to the nearest 50 cents, which is $0.50. Therefore, the cost of four stamps can be estimated as 4 multiplied by 0.50, which is $2.00.
