Answer:

m∠A = 9°

Step-by-step explanation:

\sin 7A =  \cos 3A \\  \\ \sin 7A =  \sin(90 \degree -  3A) \\  \\ 7A =  90 \degree -  3A\\  \\ 7A  + 3A=  90 \degree  \\  \\ 10A=  90 \degree  \\  \\ A =  \frac{90 \degree}{10}  \\  \\  m \angle A =9 \degree

Ariel was told the x intercept and the y intercept of a line with a positive slope. Yet, it was impossible for Ariel to find the
alexdok [17]

A line has the following standard equation form:

y = m x + b

where m is the slope and b is the y intercept

 

So if Ariel cannot find the slope, then this would only mean that m = 0, there is no slope. And hence the line is either a straight vertical line or straight horizontal line.

 

Answer:

<span>There is no slope</span>

B) f(x) = (10 - 3x)(4 - 5x)
babymother [125]

Answer:

x=10/-3, 4/5

Step-by-step explanation:

f(x) = (10 - 3x)(4 - 5x)

10-3x=0

-3x=-10

x=10/3

4 - 5x = 0

-5x = -4

x = 4/5
