Answer:
y = 3x + 19
Step-by-step explanation:
Point slope formula: y-y1=m(x-x1)
y - 4 = 3(x - (-5))
y - 4 = 3(x + 5)
y - 4 = 3x + 15
y = 3x + 19
400(1.07)=428
28(5)=140
140+400= 540.
$540 is your answer
Answer:
4
Step-by-step explanation:
If sandwiches are 6 dollars each, then chips are 3 dollars, she only bought 5 sandwiches for 6 each for 30 dollars(5*6=30).So, she has 12 dollars left to spend since she spent 42 dollars. And 4 *3=12so she only bought 4 bags of chips.
Answer:
$308, $294, large
Step-by-step explanation:
294 is less than 308, so the large is the better deal
The correct factorization would be (5x - 4)(25x^2 + 20x + 16).
The law of factoring cubes states that we use the following formula when we have two cubes being subtracted by one another.
(a - b)(a^2 + ab + b^2)
If we take the cube root of 125x^3 we get 5x, which will be our a value. If we take the cube root of 64, we get 4, which will be our b value. Then we plug in to the formula.
(5x - 4)((5x)^2 + (5x)(4) + 4^2)
(5x - 4)(25x^2 + 20x + 16)
I think the problem with your second answer is that you just did not properly multiply the 5x and the 4 to get 20x (instead you got 15x).
