Answer:
A line goes through the points (7, 3) and (–1, 5).
To find:
The equation of the line in point-slope form.
Solution:
The lines goes through the points (7, 3) and (–1, 5). So, slope of line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{5-3}{-1-7}[/tex]
[tex]m=\dfrac{2}{-8}[/tex]
[tex]m=-\dfrac{1}{4}[/tex]
So, slope of the line is [tex]m=-\dfrac{1}{4}[/tex].
Now,
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope and [tex](x_1,y_1)[/tex] is any point on the line.
If slope of line is [tex]m=-\dfrac{1}{4}[/tex] and the point is (7, 3), then point slope form of line is
[tex]y-3=-\dfrac{1}{4}(x-7)[/tex]
If slope of line is [tex]m=-\dfrac{1}{4}[/tex] and the point is (-1, 5), then point slope form of line is
[tex]y-5=-\dfrac{1}{4}(x-(-1))[/tex]
Therefore, the required equations are either [tex]y-3=-\dfrac{1}{4}(x-7)[/tex] or [tex]y-5=-\dfrac{1}{4}(x-(-1))[/tex].

Answer: 12.5
y = 12.5x
Step-by-step explanation:
k = y/x
= 50/4
= 12.5
Notice that you could have used: 62.5/5 = 12.5 or 75/6 = 12.5
The equation is: y = kx
y = 12.5x
1. Factor x²+5x-24
2. Factor 2n²-5n-3
Given problems;
1. Factor; x²+5x-24
To factor this equation, we must understand that this is a quadratic equation.
A quadratic equation usually has two roots.
Equate to zero;x²+5x-24 = 0
Then find two numbers whose product is -24 and their sum is +5the numbers are +8 and -3
then replace 5x with the number;
x² + 8x - 3x - 24 = 0
Now factorize;
x(x +8) - 3(x + 8) = 0
(x-3)(x+8) = 0
Factoring gives (x-3)(x+8)
2. Factor 2n² - 5n -3;
Equate to zero;
2n² - 5n -3 = 0
Find the number whose sum is -5 and the product gives -6( 2 x -3);
the number is -6 and +1;
2n² - 6n + n -3 = 0
2n(n-3) + 1(n-3) = 0
(2n + 1)(n-3) = 0
The factor of the equation is (2n + 1)(n-3).

A cyclist rode 3.75 miles in 0.3 hours.
How fast was she going in miles per hour?
At that rate, how long will it take her to go 4.5 miles?
Answer:
A. 12.5 miles per hour B. 0.36 hours
Step-by-step explanation:
3.75/.30=12.5 , so divide 3.75 by the time 0.30 hours and you get your miles per hour
next, take 4.5 and divide by the new mph 12.5 from your previous answer.
4.5/12.5=0.36 hours
Answer:
1.) 12.5 miles per hour 2.) 0.36 hours

Janet's money does Emma have?
A
0.625%
B
1.60%
C
55%
D.
62.5%
Answer:
i think it's D. because 55% isn't enough, but very close, and 0.625% is waaaay too little, and the same for 1.60.
Step-by-step explanation:
estimation.
The percentage of Janet's money does Emma have is D. 62.5%.
Given that,
Janet has $40. She gives $25 to Emma.Based on the above information, the calculation is as follows:

find the area of the right triangle.
Answer:
well its 2 across and 5 up and down
so you take 2 times 5 to get 10 but sense its a triangle you have to divide by 2 so the answer would be 10 divided by 2= 5 units squared
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
The area of each square is equal to 1.
We can see that two triangles could form a rectangle with 10 units of area, so it's just divide it.
10/2=5units

W = F(r + A); Solve for r
Answer:
W/F - A = r
Step-by-step explanation:
W = F(r + A)
Divide each side by F
W/F = F/F(r + A)
W/F = (r + A)
Subtract A
W/F - A = r+A-A
W/F - A = r

Answer:
put 6 over 1 then look for the LCM of 7 and 1 the LCM is 7 then ask yourself how times does seven go into 7 one time right so multiply 1 by 3(2a - 1) then ask yourself how many times does 1 go into 7 it goes 7 times right multiply 7 by 6 so your equation is like this 3(2a - 1) = 42 open the bracket so it will be 6a - 3 = 42 collect the like terms so 3a = 42+3, 3a =45 , divide both sides by 3 so x =15

-4 minus 2 would be -6
PLZ HELP MEEEE!!!!!!!!!!!!!!!
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation:
1) The product of a number and -7 is 63
2) 10 subtracted from a number is 15
3) two-fifths of a number is -12
4) 8% of a number is 20
5) the sum of twice a number and 17 is -1
6) nine less than the product of a number and -4 is 35
Step-by-step explanation:
let the no. be x
for 1,
x× -7 = 63
or, x= 63 ÷ -7
or, x = -9
therefore -9times -7 is 63.
for 2
by question
x -10= 15
or, x = 15+10
or, x = 25
therefore 25 minus 10 equals 15.
for 3
by question
(2/5) of x = -12
or, x = -12×(5/2)
r, x= -6×5
or, x = -30
therefore 2/5 of -30 is -12
for 4
by question,
8%of x = 20
or, 8x/100=20
or, 8x = 20×100
or, x = 2000÷8
or, x= 250
therefore 8% of 250 is 20.
for 5
by question,
2x+17 = -1
or, 2x = -1 -17
or, 2x = -18
or, x = -18 ÷ 2
or, x =-9
therefore -9 times 2 plus 17 equals -1.
for 6 dont know
which of the following is the standard form of 36 / 24
Answer:
15 x 10^-1
Step-by-step explanation:
36÷24=1.5
In this case I'm considering 15 as the base of my standard form.
To make 15 a 1.5, you'll have to move from right to left one unit and on the number line moving from the right to left gives you a negative number of units moved
1. At Chesterfield Town Center, Alex is at the Barnes and Noble at coordinates (-10,9) and Jeff is at the Macy's which is at (4,-6). They decide to meet for lunch in the food court which is halfway between their locations. What are the coordinates of the food court?
Answer:
(-1,-1)
Step-by-step explanation:
The easiest way I know how to explain it is you put the numbers on a line for instance
-6, -5,-4,-3,-2,-1,0,1,2,3,4
and the number in the very middle of the y then for x
-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9
and then again you use the midpoint for the x
because they are trying to meet each other half way you are trying to find the midpoint.
