Which point-slope equation represents a line that passes through (3, –2) with a slope of negative StartFraction 4 Over 5 EndFrac

Schach [20]

Answer:

y + 2 = (-4/5)(x - 3)

Step-by-step explanation:

Your slope is -4/5. Your line passes through (3, -2).

Applying the point slope formula, we get:

y + 2 = (-4/5)(x - 3)

What is the slope G(8,1) & H(8,-6).

Gennadij [26K]

M=slope=(y2-y1)/(x2-x1)=(-6-1)/(8-8)=-7/0 which is technically undefined. This is just a vertical line namely:

x=8 (you can think of a vertical line as having infinite slope)

If a student is 65.0 in tall, what is her height in m? (2.54 cm = 1 inch)

spayn [35]

Answer:

Height of the student=1.651m

Step-by-step explanation:

Given: Height of a student= 65.0 inch.

To find: Height of a student in meters.

Solution:

We know that 1 inch=2.54 cm, then

65.0 inch will be = $2.54{\times}65.0$

65.0 inch will be= $165.2 cm$

Also, we know that 1cm= $\frac{1}{100} m$ , then

165.2 cm will be equal to= $\frac{1}{100}{\times}165.1$

165.2 cm will be equal to= $1.651 meters$

Therefore, the height of a student in meters will be 1.651 meters.

What is 1 2/5 × 2<br>what is 1/4 × 1

Mrrafil [7]

Answer:

$1).$ $2\frac{4}{5}$

$2).$ $\frac{1}{4}$

Step-by-step explanation:

$1).$ $1\frac{2}{5}*2$

Convert mixed number to improper fraction: $a\frac{b}{c} =\frac{a*c+b}{c}$

$1\frac{x2}{5} =\frac{1*5+2}{5} =\frac{7}{5}$

$\frac{7}{5} *2$

$\frac{7}{5} *2$

Apply the fraction rule: $\frac{a}{b}*c =\frac{a*c}{b}$

$\frac{7}{5} *2=\frac{7*2}{5}$

$=\frac{7*2}{5}$

Multiply the numbers: $7*2=14$

$=\frac{14}{5}$

Convert improper fractions to mixed numbers: $\frac{14}{5}$

$\frac{14}{5}$

Write the problem in long division format:

$\begin{matrix}5\overline{|\smallspace14}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Divide $14$ by $5$ to get $2$

$\begin{matrix}\space\space\space\space\space\space\emptyspace2\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace14}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Multiply the quotient digit $(2)$ by the divisor $5$

$\begin{matrix}\space\space\space\space\space\space\emptyspace2\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace14}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace1\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Subtract $10$ from $14$

$\begin{matrix}\space\space\space\space\space\space\emptyspace2\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace14}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace1\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\space\space\emptyspace4\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

The solution for long division of $\frac{14}{5}$ is $2$ with a remainder of $4$

$2\quad \mathrm{Remainder}\quad \:4$

Convert to mixed number: $Quotient\frac{Remainder}{Divisor}$

$\frac{14}{5} =2\frac{4}{5}$

$=2\frac{4}{5}$

$2\frac{4}{5}$

Convert $\frac{4}{5}$ to decimal using long division

$\frac{4}{5}$

Divide $4$ by $5$ to get $0$

$\begin{matrix}\space\space\space\space\emptyspace0\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace4}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Multiply the quotient digit $(0)$ by the divisor $5$

$\begin{matrix}\space\space\space\space\emptyspace0\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace4}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Subtract $0$ from $4$

$\begin{matrix}\space\space\space\space\emptyspace0\space\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace4}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\emptyspace4\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Add a decimal place and a zero to the dividend

Bring down the zero from the dividend

$\begin{matrix}\space\space\space\space\emptyspace0.\space\space\space\space\space\space\space\space\space\space\space\\ 5\overline{|\smallspace4.0}\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace0}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\emptyspace4\emptyspace0\space\space\space\space\space\space\space\space\space\space\end{matrix}$

Divide $40$ by $5$ to get $8$

$\frac{40}{5} =8$

The solution for long division of $\frac{4}{5}$ is $0.8$

$=2+0.8$

Add $2+0.8=2.8$

$2).$ $\frac{1}{4} *1$

Multiply $\frac{1}{4} *1=\frac{1}{4}$

$=\frac{1}{4}$

Anything multiplied by $1$ is the same number.

Divide the the numbers $\frac{1}{4}$ to get decimal form

Divide $1$ by $4$

$\frac{1}{4} =0.25$

$=0.25$

Challenge The price of Stock A at 9 A.M. was $14.63. Since then, the price has been increasing at the

lozanna [386]

9514 1404 393

Answer:

2.5 hours

Step-by-step explanation:

The price of stock A is described by ...

A = 14.63 + 0.09t . . . . . . where t is time in hours after 9 A.M.

And the price of stock B is ...

B = 15.13 - 0.11t

The two prices will be equal when ...

A = B

14.63 +0.09t = 15.13 -0.11t

0.20t = 0.50 . . . . . . . . . . . . . add 0.11t -14.63 to both sides

t = 0.50/0.20 = 2.5

The prices of the two stocks will be the same in about 2.5 hours.
