Please help me ASAP <br> I will give brainliest
stellarik [79]

Answer:

-23

Step-by-step explanation:

rearrange to point slope form first

slope can be fine by y2-y1/x2-x1 (im using the first 2 points)

so 13-25 = -12 and -54-(-72) = 18, and the slope is -12/18 which is -2/3

then you can use any point (i used the first point) to create the point slope form which is y-ypoint=slope(x-xpoint) and equation would be y-25=-2/3(x+72)

turn it into slope intercept form by multiplying -2/3 within the equation and adding -25 on both sides

you will get y= -2/3x-23

and the y intercept will be (0, -23)

Work out in a standard form. <br>A) 2.1x 10^-5 ÷7 x 10^-2​
EleoNora [17]

\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}

<h3>Given:</h3>

▪ \longrightarrow \sf{\dfrac{2.1 \times  {10}^{5} }{7 \times  {10}^{ - 2} } }

First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:

\small\longrightarrow \sf{\dfrac{21 \times  {10}^{ - 6} }{7 \times  {10}^{2} } }

Divide the coefficient:

\small\longrightarrow \sf{21 \div 7=3}

Divide the base by subtracting the exponents of the base 10.

\small\longrightarrow \sf{-6(-2) \Longrightarrow -6+2=-4}

\leadsto Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.

\small\longrightarrow \sf{3 \times 10^{-4}}

\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}

\large \bm{The \:  \: quotient \:  \: is  \: \: 3 \times  {10}^{ - 4} .}
