Answer:
The total number of jumping jack done by Linda in a week is 225
Step-by-step explanation:
Given as :
The jumping jack for first three night = 75
The jumping jack for the remaining 4 nights = 2 times 75
= 2 × 75 = 150
The total number of jumping jack done by Linda in a week = 75 + 150
Or, The total number of jumping jack done by Linda in a week = 225
Hence The total number of jumping jack done by Linda in a week is 225 Answer
Here's a graph. Remember that the y intercept crosses the y axis.
Answer:
f(4) = 3
x = -1
Step-by-step explanation:
Line graphed shows a linear function.
Since this line passes through two points (4, 3) and (-1, 4)
Let the function is,
f(x) = mx + b
where 'm' = slope of the line
b = y-intercept of the line
Slope 'm' =
=
=
f(x) =
Since a point (4, 3) lies on the line,
f(4) =
3 =
b = 3 + 0.8
b = 3.8
Therefore, f(x) = -0.2x + 3.8
For x = 4
f(4) = -0.2(4) + 3.8
= -0.8 + 3.8
= 3.0
For f(x) = 4
4 = -0.2x + 3.8
0.2x = 3.8 - 4
x =
x = -1
Answer:
Step-by-step explanation:
x + y = -6
2x - y = 3
3x = - 3
x = -1
-1 + y = -6
y = -5
(-1, -5)
In x^7•x^4, how many x’s are multiplied together? (There’s 7 in the first factor and 4 in the second.)
x^7•x^4 = x^__? This is your a-value.
Similarly, y^2•y^5 = y^__? How many y’s are there in total being multiplied? This is your b-value.
