Which sentence contains a pronoun with an unclear, a missing, or a confusing antecedent?

Arte-miy333 [17]

Answer:

B. They say that doing homework leads to his success in school.

Step-by-step explanation:

Looking at the answers, C and D already make sense, so they're not the answers. The answer A does not have an unclear antecedent because "my mom and me" would not be written as "my mom and I". B is the only answer left. If you look at the sentence, it begins with "they", and it ends up saying "his success in school". This sentence includes a confusing antecedent because the sentence does not define the person who it is describing.

Sorry if this explanation was confusing. I hope this helps! Have a great day!! C:

The midpoint of RS¯¯¯¯¯¯¯ is M. Use the given endpoint R(23, 14) and midpoint M(13, 8) to find the coordinates of the other endp

Oksanka [162]

The coordinates of other endpoint S is (3, 2)

<h3><u>Solution:</u></h3>

Given that midpoint of RS is M

Given endpoint R(23, 14) and midpoint M(13, 8)

To find: coordinates of the other endpoint S

<em><u>The formula for midpoint is given as:</u></em>

For a line containing containing two points $(x_1, y_1)$ and $(x_2, y_2)$ midpoint is given as:

$m(x, y)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

Here in this problem,

m(x, y) = (13, 8)

$(x_1, y_1) = (23, 14)\\\\(x_2, y_2) = ?$

Substituting the given values in above formula, we get

$(13,8)=\left(\frac{23+x_{2}}{2}, \frac{14+y_{2}}{2}\right)$

Comparing both the sides we get,

$\begin{aligned}&13=\frac{23+x_{2}}{2} \text { and } 8=\frac{14+y_{2}}{2}\\\\&26=23+x_{2} \text { and } 16=14+y_{2}\\\\&x_{2}=3 \text { and } y_{2}=2\end{aligned}$
