Which equation represents a line with a slope of -8 and
a y-intercept of 4?
A y = -8x+4
B y = -4x+8
C y = - 8x-4
D y = 8x+4
Answer: A. y = -8x + 4 because the slope goes in front with the x (-8x) and the y intercept is after the slope (4)

The solution of a linear equation with rational coefficients is a rational number. A. Always B. Never C. Sometimes
9514 1404 393
Answer:
A. Always
Step-by-step explanation:
A linear equation with rational coefficients can be written in the form ...
ax +b = 0
The solution for the variable x is ...
x = -b/a
The problem statement tells us that 'a' and 'b' are rational numbers. Assuming there is a solution (a≠0), that solution is the ratio of rational numbers, hence must always be rational.

You have 7 times as many nickels
as pennies. You have 16 nickels
and pennies altogether. How
much money do you have in all?
The total money you have is $40.14.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
There are 7 times as many nickels as pennies
Let there are n nickles and p pennies.
⇒ p = 7n
Now, there are 16 nickels and pennies altogether
⇒ p + n = 16
Put p = 7n we get,
⇒ 7n + n = 16
⇒ 8n = 16
⇒ n = 16/8
⇒ n = 2
Therefore, p = 7*2
⇒ p = 14
Thus there 14 pennies and 2 nickels.
Now, since 1 penny = 0.01 dollars
and 1 nickel = 20 dollars
⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar
and, 2 nickel = 2*20 dollars = 40 dollars
So, Total money = $40 + $0.14
⇒ Total money = $40.14
Thus, the total money you have is $40.14.

check all that apply. if csc0 =13/12 then:
a:tan0= 12/5
b:sec0= 12/13
c: sin0=12/13
d: cos0=12/13
Answer:
a:tan0= 12/5
c: sin0=12/13
Step-by-step explanation:
cosec t(heta) = 13/12
1/sin t = 13/12
sin t = 12/13
cos t = √ (1 - (12/13)² ) = √ ( 1 - 144/169 ) = √25/169
cos t = 5/13
tan t = sin t/ cos t = (12/13) / (5/13) = 12/5
sec t = 1 / cos t = 13/5
Answer: A ) and C ) are correct:
tan theta = 12/5 and sin theta = 12/13
