An operation is defined as p*q=-5q+p2 evaluate. 2*(7*3)
Answers
Answer:
- 166
Step-by-step explanation:
First step is to evaluate 7*3
7*3 ( with p = 7 and q = 3 )
= - 5(3) + 7²
= - 15 + 49
= 34
Now evaluate
2*34 ( with p = 2 and q = 34 )
= - 5(34) + 2²
= - 170 + 4
= - 166
What is the solution to the system of equations?
y = 2x -1
y = -x +5
Answers
x= −2 and y=3
I can't explain this very well, sorry.
x= 4/3
y= 11/3.
Step by step: (substitution)
2x+1=-x+5
Add x to both sides.
3x+1=5.
Subtract 1.
3x=4.
Divide by 3.
x=4/3.
Use 4/3 instead of x to find y.
y=-(4/3)+5
y= 11/3.
Hope this helped!! :)
Find the equation of the line that passes through (3,-4) and is parallel to 3x+y+2=0
Leave your answer in the form y=mx+c
Answers
Answer:
y=-3x+5
Step-by-step explanation:
it parallel to 3x+y+2=0 => line is: 3x+y+c=0
It through (3;-4) => 3(3)+(-4)+c=0 <=> c=-5
Line is 3x+y-5=0 => y=-3x+5
Answer:
Since it’s parallel to 3x+y+2=0 then it must be of the form 3x+y+k=0. Since (3,-4) is on the line we have 0=3*3-4+k=k+5, therefore k=-5 and the equation is 3x+y-5=0
In the form y=mx+c this becomes y=-3x+5

Answers
The best measure of center for the heights help Nancy to determine the sizes of cloth for countries, as it does not include outliers
What is mean of the data set?The mean of the data is the average value of the given data. The mean of the data is the ratio of the sum of all the values of data to the total number of values of data.
The mean of the data is the center tendency and includes the outlines.
The value for the best measure of center for the heights of the adult males help can help Nancy in two ways:
She can send the same distributions of sizes to each country for the men’s clothing line She needs to adjust the distributions she sends.Here, when Nancy uses the mean of the data of height, she also measures the outliers. This affect the calculation of her. With the best measure of center, help her to deter line the size.
Thus, the best measure of center for the heights help Nancy to determine the sizes of cloth for countries, as it does not include outliers.

the general point-slope form is
y - y1 = m(x - x1)
m is the slope.
x1 and y1 are the point coordinates.
