Answer:</h2>
First we must find the opposite-reciprocal of the original slope.
current slope: ![\frac{7}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D)
new slope: ![-\frac{3}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B7%7D)
Using the new slope and the given point, we will plug them into slope-intercept form and solve for b, the y-intercept.
![9 = -\frac{3}{7}(-4) + b\\\\9 = \frac{12}{7} + b\\\\-\frac{51}{7} = b](https://tex.z-dn.net/?f=9%20%3D%20-%5Cfrac%7B3%7D%7B7%7D%28-4%29%20%2B%20b%5C%5C%5C%5C9%20%3D%20%5Cfrac%7B12%7D%7B7%7D%20%2B%20b%5C%5C%5C%5C-%5Cfrac%7B51%7D%7B7%7D%20%3D%20b)
The y-intercept is
.
Now, we can write the formula for the new line.
Slope-intercept form: ![y = -\frac{3}{7}x - \frac{51}{7}](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B3%7D%7B7%7Dx%20-%20%5Cfrac%7B51%7D%7B7%7D)
Point-slope form: ![y - 9 = -\frac{3}{7}(x + 4)](https://tex.z-dn.net/?f=y%20-%209%20%3D%20-%5Cfrac%7B3%7D%7B7%7D%28x%20%2B%204%29)
Answer:
$5700 - $5500= $200
Explanation:
The total installments: 24 ($175) = $4200
The hire purchase price: $1500 + $4200 = $5700
The amount saved by paying cash: $5700 - $5500= $200
Answer:
Step-by-step explanation:
Day 1 = 2 birds
day 2 = 3 birds
day 3 = 9 birds
day 4 = 8 birds
day 5 = 1 bird
On day 1 the points are (1,2)
On day 5 the points are (5,1)
(I am picking these for the points because I don't know your options for the selecting area.)
we use this formula y2-y1/x2-x1
2-5/1-1
3/0
our answer is infinite which is the relation and this is an infinite function
Answer:
4.5
miles
Step-by-step explanation:
Well, he runs
3
miles in
28
minutes. Also, see that
42
=
28
⋅
1.5
.
So, his journey would just be running
1.5
times, with each time running
28
minutes.
So, he runs a total of
1.5
⋅
3
=
4.5
miles
