Answer: 7.45 was used as the value due to no option
Step-by-step explanation
Since options are not available, The best value he could have rounded up to nearest tenth to give 7.5 and nearest whole number to give 7 is 7.46.
This value is 7.5 to the nearest tenth due to the last value which is greater than 5 will round the value of 4 to 5 to make 7.5.
Since the value of 4 in 7.45 is not up to 5, the value will be 7 to nearest whole number.

Answer:
- pancake: $0.50
- waffle: $1.20
Step-by-step explanation:
You can model the bills using w and p for the price of a waffle and pancake, respectively.
10w + 4p = 14
5w +8p = 10
Subtract half the first equation from the second:
(5w +8p) -(1/2)(10w +4p) = (10) -(1/2)(14)
6p = 3 . . . . . . . simplify
p = 0.50 . . . . . divide by 6
10w + 4(0.50) = 14 . . . . substitute into the first equation
10w = 12 . . . . . . . . . . . . subtract 2
w = 1.20 . . . . . . . . . . . . .divide by 10
A waffle costs $1.20; a pancake costs $0.50.
Answer: Choice A) 8
------------------------------------------------------------------
If you plot all of the points, you'll see they all fall on the same straight line. The slope of this line is m = -4
Each time x increases by 1, y decreases by 4
Going in reverse, if we decrease x by 1, then we increase y by 4
So the pair (x,y) = (1,4) shown in row 2 will lead to (0,8) if we use the trick of increasing y by 4 when decreasing x by 1.
Another way to see this is to use m = -4 with (x,y) = (1,4) and you'll find that b = 8. So the equation of this line is y = -4x+8
Or you can use a graphical method to find the y intercept
Either way, the answer is 8. This is where the graph crosses the y axis.
Answer:
x=2 if i can have brainliest that would be great
Step-by-step explanation:
4x+6+3=17
(4x)+(6+3)=17(Combine Like Terms)
4x+9=17
4x+9=17
Step 2: Subtract 9 from both sides.
4x+9−9=17−9
4x=8
Step 3: Divide both sides by 4.
4x/4=8/4
x=2
Slope for f(x):
Slope for g(x)
y = mx + b
y = 5x + 1
m = 5
The slope for f(x) is twice the slope of g(x).
B. f(x)'s y-intercept is -1 because y = -1 when x = 0. g(x)'s y-intercept is 1 because 1 is in the "b" spot in y = mx + b. g(x) has the greater y-intercept.
