1. None of the answer choices are correct, because the length that were to go with those numbers don't fit. The answer is D.

2. One coffee cost $4 and a latte would cost $2.50, because the other prices for a cup of coffee would exceed the price of the total of two coffees plus one latte and three coffees plus two lattes. The answer is A: $4.00.

3. This one has to be A, because you're finding how many nickels and dimes there are together if there are 24 coins. A nickel is 5 cents each and a dime is 10 cents each. The total of them combined is $1.85. The answer is A.

Graph 14x+34y=1 pretty please with a cherry on top!Also thank-you

Svetlanka [38]

To make it much easier, it should be converted to the slope-intercept form
y = mx + b

To do so, 14x + 34y = 1 turns to:
34y = -14x + 1

Divide both sides by 34:
$\frac{34y}{34} = \frac{-14}{34} x + \frac{1}{34}$
Simplified:
$y = \frac{-7}{17} x + \frac{1}{34}$

Answer: $y = -\frac{7}{17} x + \frac{1}{34}$
Here is the graph:

What is y – 3 = 7 (x – 5) in standard form?

yuradex [85]

Answer:

38=7x-y

Step-by-step explanation:

standard form= Ax+By+C

(y-3=7(x-5))

(y-3=7x-35)+3 to both sides

(y=7x-38) +38 to both sides

(y+38=7x) -y to both sides

38=7x-y

you have to move the 38 and y because if you moved the x value, than A becomes negative and it can't be in standard form
