Slope intercept from y-4=-3(x-3) step by step please

1 answer:

7 0

Okay first you need to do distribute the -3 to remove the parentheses:

y - 4 = -3x + 9

Then you need to move -4 to the right by adding on both sides

y = -3x + 9 + 4

The answer is —> y = -3x + 13

A recipe that makes 8 servings calls for 3/5 cup of flour. Jeff modifies the recipe so that it can serve 10. How many cups of fl

Blababa [14]

8 goes with 3/5: 10 goes with n (n being the number of cups)

$\frac{8}{3/5} = \frac{10}{n}$

Use cross products and we get 8n = 6
Now divide by 8
8n = 6
8 8

n= 6/8 or 3/4 of a cup of flour.

The leaning tower of Pisa currently "leans" at a 4 degree angle and has a vertical height of 55.86 meters. How tall was the lean

Marizza181 [45]

Answer:

56 meters.

Step-by-step explanation:

Please find the attachment.

Let the leaning tower's be h meters tall, when it was originally built.

We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.

Since we know that cosine relates the adjacent and hypotenuse of a right triangle.

$\text{Cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}$
