Answer:
y + 5 = -7(x - 4)
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h):
Substitute 4 for h, -5 for k and -7 for m:
y + 5 = -7(x - 4)
Answer:
y = -7x + 23
Step-by-step explanation:
We are given that a line has a slope of -7 and passes through the point (4, -5)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept
As we are already given the slope, we can immediately substitute it into y=mx+b.
Replace m with -7.
y = -7x + b
Now we need to find b.
As the equation passes through (4, -5), we can use it to help solve for b.
Substitute 4 as x and -5 as y.
-5 = -7(4) + b
Multiply
-5 = -28 + b
Add 28 to both sides
23 = b
Substitute 23 as b in the equation
y = -7x + 23

The mean number of lessons for group A is greater than the mean
for group B by 1 MAD
B. The mean number of lessons for group A is greater than the mean
for group B by 2 MAD
C. The MAD for group A is more than the MAD for group B
D. On average, the dogs in group B required more lessons than the
dogs in group A
Answer:
The mean number of lessons for group A is greater than the mean for group B by 1 MAD
Step-by-step explanation:
Given the table :
_______Mean number of lessons ____ MAD
GRP A _____ 5 ___________________ 2
GRP B _____ 3 ___________________ 2
With group A having a mean number of lessons of 5 and Group B having a mean number of lessons of 3
Mean of A > mean of B ; hence, Group A dlgs tool more lessons to learn the trick than group B dogs.
The mean absolute deviation (MAD), measures how far a value is from the mean
Difference in mean number of lessons :
5 - 3 = 2
2 lessons ;
Number of mean absolute deviations:
Difference / MAD value = 2 / 2 = 1
Answer:
The mean number of lessons for group A is greater than the mean for group B by 1 MAD.

Your business loan has a variable interest rate. Next month the annual rate will jump from 6.3% to 7.8%. Your balance is
$1,620,000. How much will your monthly payment go up?
Answer:
$2,025
Step-by-step explanation:
The monthly payment will be increased by $2,025.
What is an amount?
The quantity of money anyone has is termed as the amount. Your monthly payment based on the rate of 6.3% per annum is:
= (6.3% * 1,620,000 ) / 12 months
= 102,060 / 12
= $8,505
Now that the rate has gone up to 7.8% per annum, the payment is:
= (7.8% * 1,620,000 ) / 12 months
= 126,360 / 12
= $10,530
Payment went up by:
= 10,530 - 8,505
= $2,025
Therefore the monthly payment will be increased by $2,025.

Answer:
If the arrow is spun 400 times how many times would it be expected to ... 3 green. 20 total 10. Adrian spins the arrow on this spinner once. Which number is the arrow... Part B. Use a paperclip and the tip of your pencil to spin
Answer:
I know this was two weeks ago, but here is my answer: 1/9
Step-by-step explanation:
Baron here is going to spin this twice, and he wants to get a 3 on both, no?
Well, there are 3 sides; 1, 2 and 3, meaning that it will look something like this: ??/3.
He only wants to have one of the options, so that ??/3 will turn into a 1/3.
That would be for one spin, but he's going to do two.
SO, it would be a 1/3 chance of getting it on the first try, and a 1/3 chance on getting it on the second, multiply them together for the complete probability, and BAM you get 1/9.
There is an easier way, but it would take too long to write.
Hope you this helps you understand if you are still confused.

Answer:
Problem 1:
Coefficients are : 3 & 2
Variables are: w & b
Number of terms: 2
Constant: none
Problem 2:
Coefficients are : 6 & -2
Variables are: xy & c
Number of terms: 3
Constant: 4
Problem 3:
Coefficients are : [tex]\frac{2}{3}[/tex] & -3
Variables are: y & p
Number of terms: 2
Constant: none
Step-by-step explanation:
Okay, lets break this down.
An Algebraic expression is not meant to be solved, but rather used to determine the various components inside of it to better understand how to solve equations later on. Although for now lets look at these problems. :
A Coefficient in terms of algebra, is the number before a variable. In other terms, a coeffiecient is the number before the letter such as 3w. Looking at 3w we see that there are two parts: 3, and w.
The number 3 is the coefficient while the variable is the letter w. Variables are always the letters.
Variable: A letter used to determine an unknown value such as x
Now a term is a single mathematical expression. It may be a single number (positive or negative), or a single variable ( a letter). (Can also be a coeffient with a variable multiplied or divided by one another as such :
[tex]3w = 3*w\\\frac{3}{w} = 3 / w[/tex]
Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
Now with that said, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.
With all of that said, lets look at the problems given:
Problem 1:
Coefficients are : 3 & 2
Variables are: w & b
Number of terms: 2
Constant: none
Problem 2:
Coefficients are : 6 & -2
Variables are: xy & c
Number of terms: 3
Constant: 4
Problem 3:
Coefficients are : [tex]\frac{2}{3}[/tex] & -3
Variables are: y & p
Number of terms: 2
Constant: none

The length (L) of the figure is 11 mm and the width (w) is 9 mm. What is the perimeter of the shaded region? Round to the nearest tenth.
Answer:
50.3 mm
Step-by-step explanation:
The perimeter of the shaded region = perimeter of a full circle + 2(Length)
= πd + 2(L)
diameter (d) = width = 9 mm
Length (L) = 11 mm
Perimeter of the shaded region = π*9 + 2(11)
= 50.2743339 ≈ 50.3 mm (nearest tenth)

14.9
Step-by-step explanation:
The answer is 14.9 because you have to get a2 + b2 = c2 or in other words (14x14=196) + (5x5=25 because you have to divide the 10) = (221) then you need to do the square root. 2√221 = 14.86606874731851. Now round 14.86606874731851 and you get 14.9
Angles a and b are in the fourth quadrant. If sin a = -12/13 and cos b = 20/29 find tan (a+b)
Answer:
tan (a+b) = 2.27 or (345/152)
Step-by-step explanation:
a and b are in the fourth quadrant
sin a = -12/13 tan a = - 12/5 = - 2.4
cos b = 20/29 tan b = - 21/20 =.1.05
tan (a+b) = (tan a + tan b) / (1 - tan a * tan b)
= (-2.4 + - 1.05) / ( 1 - (-2.4)*(-1.05))
= (-3.45) / (-1.52)
= 2.27
