Thank you but can u Please help — Neil is going to a bookstore 45 miles away. The bridge was closed on the way back, so
he had to take an alternate route and had to drive 15 mph slower, which make the trip
back take 7 minutes longer. How fast was he going on the way to the bookstore?

Calculate the equation of the line if two points are (1,6) and (5,0) Hint, you will have to find the slope of the line and then

motikmotik

Answer:

The equation is $y=\frac{-3}{2} x-9$

Step-by-step explanation:

First, you will have to find the slope of the two points.To do that, you will have to use the formula : $m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$

Our points are $(1,6)$ and $(5,0)$

We will have to substitute the points into the formula.

$m=\frac{0-6}{5-1}$

Then, we will simplify

$m= \frac{-6}{4}$

We could simplify that fraction into $\frac{-3}{2}$

So, our slope is $\frac{-3}{2}$

We will have to pick a coordinate point, and choose. I chose $(1,6)$

We will substitute the x-value and the y-value of the coordinate point, including our slope, to calculate the y-intercept.

The formula we will be using is $y=mx+b$

We will substitute in our values which will make it look like:

$6=\frac{-3}{2} (1)+b$

We will then multiply $\frac{-3}{2}$ by $1$ which will stay the same.

Then, we will multiply $\frac{-3}{2}$ by $6$ which will equal $-9$

$-9=b$

Hence, the equation for our line is $y=\frac{-3}{2} x-9$

Hope it helped:D

Find the area of the kite

Thepotemich [5.8K]

Step-by-step answer:

Area of a kite is half of the product of the diagonals.

The length of diagonal in the x-direction is 4+5 = 9

The length of diagonal in the y-direction is 4+4 = 8

Therefore

Area of kite = 8*9/2 = 36 units.

Luisa and Connor had $360 altogether . After Connor gave Luisa 2/5 of his money, she had the same amount of money has he did. Ho

Liula [17]

Answer:

$300

Step-by-step explanation:

Let's say that L is the amount of money Luisa had in the beginning, and C is the amount of money Connor had in the beginning.

C + L = 360

C - 2/5 C = L + 2/5 C

Simplifying the second equation:

3/5 C = L + 2/5 C

1/5 C = L

Substituting into the first equation:

C + 1/5 C = 360

6/5 C = 360

C = 300

Connor originally had $300, and Luisa $60. Connor gave Luisa $120, and they both had $180.

There are two approaches to solving the equation -3x + 10 = 4x - 20 Subtract 4x from both sides. OR Add 3x to both sides. –7x +

Scrat [10]

Answer:

There are two approaches to solving the equation -3x + 10 = 4x - 20. The value of x after solving in both methods is 4.2857.

Solution:

Given, equation is -3x + 10 = 4x – 20.

We have to solve the given equation in two methods, now let us see the first method.

1st method ⇒ by subtracting 4x from both sides.

Then, -3x + 10 = 4x – 20 ⇒ -3x + 10 – 4x = 4x – 20 – 4x ⇒ -3x – 4x = -20 – 10 ⇒ -7x = -30 ⇒ 7x = 30

Then, x = $\frac{30}{7}$

Now, let us use the 2nd method.

2nd method ⇒ by adding 3x on both sides.

Then, -3x + 10 = 4x – 20 ⇒ -3x + 10 + 3x = 4x – 20 + 3x

⇒ 10 + 20 = 4x + 3x

⇒ 7x = 30

⇒ x = $\frac{30}{7}$

Hence, the value of x after solving in both methods is $\frac{30}{7}$ = 4.2857.
