5 0

Answer: Option C is the correct answer.

Step-by-step explanation:

Triangle STU is similar to triangle SVW. This means that the ratio of the length of each side of ∆STU to the length of the corresponding side of ∆ SVW is constant. Therefore,

ST/SV = TU/VW = SU/SW

SV = 12 + 18 = 30 in

Therefore,

12/30 = TU/40

Cross multiplying, it becomes

TU × 30 = 12 × 40

30TU = 480

Dividing the left hand side and the right hand side of the equation by 30, it becomes

30TU/30 = 480/30

TU = 16

What is the slope and y-intercept of this line?

VARVARA [1.3K]

Answer:

The slope is -6 and the y-intercept is 2

Step-by-step explanation:

The slope of an equation is always the number next to x, so therefore it is -6. The y-intercept is the number that comes after the slope, which in this equation is 2. If you need me to explain more, let me know. Hope this helps!

Next number in sequence 3 -6 12 4 20 ?

Artyom0805 [142]

-6 - 3 = -9
12 - (-6) = 18
4 - 12 = -8
20 - 4 = 16
The first difference is -9. The third difference is -8.
Maybe the fifth difference is -7.
That makes the next term 13.
