4/5 of 350...." of " means multiply
4/5(350) = 1400/5 = 280 <== Jose payed $ 280
1) a
2) c
#1 explanation:
x^4-20x^2=-64
x^4-20x^2+64=0
(find a number that multiplies to the last number aka 64 and adds up to b aka 20)
((x-4)(x-16))^2
x= -2,2,-4,4
same for #2 w different variable and numbers
Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 8, 22) and (x₂, y₂ ) = (3, 0)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 0), then
0 = - 6 + c ⇒ c = 0 + 6 = 6
y = - 2x + 6 ← equation of line
- All the listed combination of row and boxes are correct and can be chosen from.
From the question, we are asked to find the row arrangement of a stack of boxes. Let us take a look at each one of the aforelisted answers
- x rows with 16 boxes in each row
- 8 rows with x boxes in each row
- 16 rows with x boxes in each row
Since we are told that the total number of boxes to be stacked is 64, then for the first arrangement, we can deduce that the "x" is going to be 4. This is because multiplying 4 by 16 gives 64. For the second row, using the same calculation, we find that "x" is 8. And that of the third gives our "x" to be 4 as well. We can then adjudge that;
- 4 rows with 16 boxes in each row
- 8 rows with 8 boxes in each row
- 16 rows with 8 boxes in each row
Bearing this in mind, we can see that each of the 3 answers fits into the requirements we are asked.
- At least 3 rows, and at least 4 boxes in each row.
Hence, all of the options are correct.
