Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis. What are the coordinates of M'?
ANTONII [103]

Given:

Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis.

To find:

The coordinates of M'.

Solution:

We have, M(2, -1) .

If a  figure reflected over the y-axis then

(x,y)\to (-x,y)

Using this rule, we get

M(2,-1)\to M'(-2,-1)

Therefore, the coordinates of point M' are (-2,-1).

if my grade in math is a 51.32% and I get at least a 70% on my test. What percentage will my grade go up too? ( test are worth 4
bazaltina [42]
Keeping in mind that 70% of anything is 70/100 * anything, thus

\bf \begin{array}{ccll}
\stackrel{percentage}{points}&\stackrel{test}{completed}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
45&1\\\\
x&\frac{70}{100}
\end{array}\implies \cfrac{45}{x}=\cfrac{1}{\frac{70}{100}}\implies \cfrac{45}{x}=\cfrac{\frac{1}{1}}{\frac{7}{10}}
\\\\\\
\cfrac{45}{x}=\cfrac{1}{1}\cdot \cfrac{10}{7}\implies \cfrac{45}{x}=\cfrac{10}{7}\implies \cfrac{45}{x}=\cfrac{10}{7}\implies \cfrac{45\cdot 7}{10}=x
\\\\\\
\cfrac{63}{2}=x\implies \boxed{31.5=x}

so, you get that many percentage points, now... add that to 51.32.

13/5=4/x SOLVE for x to the nearest .01
Mashutka [201]
\frac{13}{5} = \frac{4}{x} 
\\\\ x*\frac{13}{5} =4
\\\\ \frac{13x}{5}=4
 \\  \\ 13x=4*5
 \\  \\ 13x=20
 \\  \\ x= \frac{20}{13}  
 \\  \\ x=20 / 13
 \\  \\ x=1.53846153...
 \\  \\ x=1.54
