Answer:
C
Step-by-step explanation:
The triangle is reflected across the y-axis and moved down 3 units.
Exact form is 469/12 decimal form is 39.083 repeating and mixed number form is 39/1/12
Answer:
so it's
3/7m<21
and we devide both sides of the inequality.
/2r-1\>7
And we can rewrite it as a compound Inequality
2r-1<7 (or) 2r-1>7 Ima give u the enter
[r<-3 or r>4 I guess it's like this❕
Answer:
y=2x
Step-by-step explanation:
compute the slope first-
(-2,1) and (2,9)
m = 9-1/2-(-2) = 8/2+2= 8/4 = 2
knowing the slope take a given point and substitute it's x and y values into the equation to solve for 'b' the y-intercept-
y = mx + b,
1 = 2(-2) + b,
1 = -4+ b,
b = 5
our equation is y = 2x + 5
if you want an equation parallel to the line it has to have the same slope. Take y = 2x
a) The function that represent this situation is y = 90 + 8x.
b) His weight be after 8 weeks is 154 lbs.
<u>Step-by-step explanation:</u>
It is given that,
- He started at 90 kilograms.
- And gained weight at a constant rate of 8 lbs a week.
a) Write a function to represent this situation. Use x and y as your variables.
- Let 'x' be the number of weeks he gained weight.
- Let 'y' be the total weight.
Hence the equation can be framed as,
Total weight = starting weight + weight gained in x weeks.
We know that, each week he gains 8 lbs. Therefore, for 8 weeks he gained 8x lbs of weight.
⇒ y = 90 + 8x.
∴ The function that represent this situation is y = 90 + 8x.
b) What would his weight be after 8 weeks?
To find his week after 8 weeks, substitute x=8 in the function y = 90 + 8x.
⇒ 90 + 8(8)
⇒ 90 + 64
⇒ 154 lbs.
∴ His weight be after 8 weeks is 154 lbs.
