Answer:

A'(4,-5), B'(1,-6), C'(2,-3)

Step-by-step explanation:

Reflect across the line y = -1 to get these points. You can count how many points it takes to get to that line and then add the same amount of points to the other side.

What are the values of x and y?
d1i1m1o1n [39]

Answer:

Step-by-step explanation:

y is the value obtained from 4 and 12

y^2  =  4 * 12            Combine

y^2 = 48                   Square root both sides.

√y^2 = √48

y = √(3 * 4 * 4)

y = 4√3

Use the Pythagorean Theorem to obtain x

x^2 = y^2 + 4^2

x^2 = 48 + 16

x^2 = 64                    Take the square root of both sides

√x^2 = √64

x = 8

Answer

  • x = 8
  • y = 4√3

Explain how to distribute the 13 to the terms inside the parentheses, then do the distribution. Use multiplication to simplify t
Nonamiya [84]

Answer:

52 + 13x

Step-by-step explanation:

To distribute something means to divide / share a part of something. The distributive property works similarly. The distributive property states that multiplying the total sum of two variables by a number is the same as the total sum of each product of individual variables and the number.

For example: a(b+c) = ab + ac

Therefore, in order to distribute the 13 into the terms inside the parentheses, you follow the distributive property and multiply each individual variable in the parentheses by 13 and add all the resulting products.

13(4 + x) = (13*4) + (13*x) = 52 + 13x

Will choose Brainliest.
oksano4ka [1.4K]

That part is total cookies as per algebraic formula x^2-(a+b)x+ab=0

Hence

The inequality is

\\ \rm\rightarrowtail x^2-30x+224>=0

\\ \rm\rightarrowtail (x-14)(x-16)>=0

\\ \rm\rightarrowtail 14\leqslant x\leqslant 16

Solution range

  • [14,16]

Atleast means the range

  • 16-14
  • 2

Atleast 2 more than Martha
