Hello! To draw a triangle, first, we have to follow a condition of existence.

This rule is:

• one of the sides must be ,bigger, ,than the absolute value, of the ,difference between the other two, sides

• the unknown side must be ,smaller ,than the ,sum of the other, two sides.

Let's write these rules using a, b, and c for the sides:

Considering a = 7.8 and b = 5.6:

[tex]\begin{gathered} |a-b|So, the third side must be smaller than 13.4 and bigger than 2.2.

Situation A
Colt1911 [192]

The equation a = 100 + 75d represents Maria's  account balance.

<u>Step-by-step explanation:</u>

Given that,

  • Maria opened a new savings  account with an initial deposit of  $100.
  • She deposits $75 into this  savings account every  two-weeks.

You need to find the equation to represent Maria's  account balance, a after she has  completed d deposits.

  • Let 'd' be the number of deposits Maria made after the initial deposit.
  • Let 'a' be the total account balance after 'd' deposits.

Therefore, the equation for the total account balance can be framed as the sum of the initial deposit and amount deposited after that.

<u>To find the amount that was deposited after the initial deposit :</u>

⇒ $75 × number of times Maria deposited.

⇒ 75 × d

The equation is written as,

⇒ a = 100 + 75d

Hence the equation a = 100 + 75d represents Maria's  account balance.

Answer:

Step-by-step explanation:

-3x - 5 = 16

add 5 to both sides of the equation

-3x = 21

divide both sides by -3

x = -7

---------------------

-4(y - 2) = 12

distribute the -4 to everything in the parentheses

-4y + 8 = 12

subtract 8 from both sides of the equation

-4y = 4

divide both sides of the equation by -4

y = -1

1-6. Indicate whether each table or graph represents a proportional
Pie

Answer:

Step-by-step explanation:

Proportional relationship means,

x ∝ y

x = ky

\frac{x}{y}=k where 'k' is the proportionality constant.

From table (1),

\frac{1}{5}=\frac{2}{9}\neq  \text{Constant}

Therefore, relationship is not proportional.

From table (2),

\frac{1}{6}=\frac{3}{18}=\text{constant}

True.

So the relationship will be proportional.

From table (3),

\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}

Which is constant.

Therefore, relationship will be proportional.

From table (4),

\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103

Which is constant for every term.

Therefore, relationship will be proportional.

PLEASE I REALLY CAN'T THINK OF ANYTHING ELSE <br> list 2 differences between y = sin x and y = cos x
r-ruslan [8.4K]

Answer:

The sine and cosine functions have several distinct characteristics: They are periodic functions with a period of 2π. ... The graph of y = sin x is symmetric about the origin, because it is an odd function. The graph of y = cos x is symmetric about the y-axis, because it is an even function.

Pls, branliest! :)
