Answer:
f(x)=x-5 is a linear function
Step-by-step explanation:
so there are no restrictions to what x can be. The domain is all real numbers. In interval notation, we show that is can be anything from negative infinity through infinity like this: This says that the lower limit of the domain is negative infinity and the upper limit is positive infinity.
Answer:
17 hours
Step-by-step explanation:
givens:
-he made $253 for 11 hours of work
-how many hours of work for $391
set a proportion
253 391
----- = ----
11 h h=hours
cross multiply
253h=391 times 11
253h=4301
divide 253 in both sides
4301/253
17 hours!
Blue:
y-intercept: (0, 4)
a slope: m = -1/2
The equation: y = -1/2x + 4 |·2
2y = -x + 8 |+x
x + 2y = 8
Red:
y-intercept: (0, 3)
the slope: m = -1/2
The equation: y = -1/2x + 3 |·2
2y = -x + 6 |+x
x + 2y = 6 |·2
2x + 4y = 12
Answer:
x + 2y = 8
2x + 4y = 12
If you mean the base is 7 units squared and the height is 3 units, the volume would be 21 units cubed.
Answer:
Yes
Step-by-step explanation:
We can make one equation other to the other to solve for x-value first;
=> -4x = x - 5
=> -4x + (-x) = -5
=> -5x = -5
=> x = -5/-5
=> <u>x = 1</u>
Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;
=> y = x - 5
=> y = (1) - 5
=> <u>y = -4</u>
<em>Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.</em>
Hope this helps!
