Answer:

Step-by-step explanation:

Comparing the given y-4=-2/5(x-1) with the standard point-slope formula for the equation of a straight line, we get

y-4=-2/5(x-1)

y-k = (-2/5)(x - 1). Thus, k = 4 and h = 1, and so one point on this new line is (1, 4).

The slope is -2/5.

First, plot a dark dot at (1, 4).

Next, starting with your pencil point on that dot, move your point 5 units to the right and then 2 units down. Plot a dark dot there.

Finally, draw a line through your two dark dots.

Answer:

8.8%

Step-by-step explanation:

We first divide the new amount by the original and close it with brackets.

Our one year will be shown as 1/1 as an indices

(761.60/700)^1/1

= 1.088

We then convert it to 0.088 and times it by 100.

0.088×100= 8.8% Compound interest rate.

This is correct as:

700×1.088= 761.6

Have a nice day! :)

(16+3)-10÷5×3^2? with explanation step by step

NemiM [27]

$(16+3)-10\div5\times3^2\text{ = 1}$

Here, we want to simplify the given expression

We shall use the order of simplification for this

The order is PEDMAS

We shall start with the terms in parentheses before we move to the exponents

We have;

$\begin{gathered} (16+3)-10\div5\times3^2 \\ =\text{ 19-10}\div5\times3^2 \end{gathered}$

Next is the exponent

$=\text{ 19-10}\div5\times9$

The next thing to do is to divide

$=\text{ 19-}2\times9$

The next thing to do is to multiply

$=\text{ 19-18}$

We then proceed to subtract;

$=\text{ 19-18 = 1}$
