u don’t need to do the explanations for the questions. Just answer each expression with correct/incorrect. thank-you :)

This would be 4/9 since You can divide both by ten and nothing else after that due to the fact that they both end in 0 and are multiples of 10 making the answer 4/9

What is BC ? Enter your answer in the box. units

EleoNora [17]

Answer:

25

Step-by-step explanation:

I'll explain in detail for those of you that want to know.

You know that since angles B and C are congruent to each other that this triangle is an isosceles triangle. Therefore, sides AB and AC are congruent to each other because that is a property of an isosceles triangle.

To solve for x, place the expressions of sides AB and AC equal to each other and solve for the unknown variable.

4x + 1 = 2x + 23

You should get that x = 11.

Substitute x = 11 into the expression for side BC to solve for the length of that side.

f(11) = 3(11) - 8

f(11) = 25

Thus, length of side BC is 25 units.

Use this way of solving for all your future questions. It's really simple :)

HELP PLEASE WITH PART A AND B!!!!!

Elden [556K]

<h2>a. Answer:</h2>

For this question we'll use the following method:

1. Let's subtract old value from new value

185$-160$ = -25$

The negative value implies that the price has decreased

2. Divide the result by the old value

25$/185$ = 0,1351

3. Convert this value to percentage:

0,1351 x 100 = 13,51%

Finally, by rounding to the nearest tenth:

13,5%

That means 13,5% decrease

<h2 /><h2>b. Answer:</h2>

1. Let's subtract old value from new value

77$-56$ = 21$

The positive value implies that the price has increased

2. Divide the result by the old value

21$/77$ = 0,2727

3. Convert this value to percentage:

0,2727 x 100 = 27,3%

Finally, by rounding to the nearest tenth:

27,3%

That means 27,3% increase

A line passes through the point (4,-6) and he a slope -3/4. Which is the equation of the line?

ANEK [815]

Answer:

The equation of the line is 3x + 4y + 12 = 0

Step-by-step explanation:

$given \: that \: the \: line \: passes \: through \: (4 , - 6) \\ and \: has \: the \: slope \: of \: \frac{ - 3}{4} \\ the \: equation \: of \: the \: line \: is \\ y - y1 = m(x - x1) \\ here \: x1 = 4 \: \: \: y1 = - 6 \: \: and \: m = \frac{ - 3}{4} \\ on \: substituting \: the \: values \: in \: formula \\ y - ( - 6) = \frac{ - 3}{4} (x - 4) \\ y + 6 = \frac{ - 3}{4} (x - 4) \\ 4(y + 6) = - 3(x - 4) \\ 4y + 24 = - 3x + 12 \\ 3x + 4y + 24 - 12 = 0 \\ 3x + 4y + 12 = 0$
