Which addition does the model below represent?
3 + (negative 1)
3 + 4
3 + (negative 4)
3 + 1
Answers
Answer:
The correct answer is 3 + -4.
Step-by-step explanation:
First the arrow begins at 0 and moves to the right 3 spaces positive, ending at 3. Then it moves backwards, which is subtracting left 4 spaces towards -1 past zero. When adding a negative to a positive, you convert it to subtraction. 3 + -4 is the same as 3 - 4. We know 4 - 3 normally is 1, but the other way around, since 4 is more than 3, we go one extra space negative to -1. Therefore, 3 + -4 is the answer.

A small plane flew 708 miles in 3 hours with the wind. Then on the return trip, flying against the wind, it traveled only 420 miles in 3 hours. What were the wind velocity and the speed of the plane? (Note: The "speed of the plane" means how fast the plane would be flying with no wind.)
Answers
Answer:
against the wind:
x - y = 715/(2+10/60)
---
with the wind:
x + y = 715/(1+50/60)
---
put the system of linear equations into standard form
---
x - y = 715/(2+10/60)
x + y = 715/(1+50/60)

Five chicken nuggets have 160 calories. How many calories are in 9 chicken nuggets?
A) 32 calories
B) 288 calories
C) 800 calories
D) 1,440 calories
Answers
Answer:
B
Step-by-step explanation:
16 Divided by 5= 32
32 x 9 = 288
Answer:
B) 288 calories
Step-by-step explanation:
First you would have to divide the calorie amount you have (160) by how many chicken nuggets the calories equal (5), which would give you 32 calories per chicken nugget. Next you multiply 32 (the calories) by 9 (the new amount of chicken nuggets), and you would get 288 calories.

Putting all given value in above equation, we get :

O y=-4x+8
O y=-2x + 6
O y=-1/4x+2
O y = 2x + 2
Answers
Answer:
y = -4X + 8
Step-by-step explanation:
Take each point and substitute for x and y. If (x,y) then 4 = -4(1) + 8 is true and -4 = -4(3) + 8. Both points satisfy the equation therfore the line passes through both points.
Answer:
y = -4 x + 8
which agrees with the first answer in the list.
Step-by-step explanation:
We first calculate the slope via the quotient formula:
Slope = (y2 - y1) / (x2 - x1)
which for our case gives:
Slope = (4 - -4) / (1 - 3) = 8 / (-2) = -4
The we calculate the y intercept by using any one of the given points (for example (1, 4)) in the general formula of a line in slope-intercept form:
y = m x + b
y = -4 x + b
4 = -4 (1) +b
4 = -4 + b
b = 4 + 4
b = 8
Then the final expression for the line becomes:
y = -4 x + 8

where,
Initial velocity, v = 60mph
Height, h = 5 feet
t = ?
After solving for t, we get t = 1.875 seconds. We then slot it back into the equation.
h = -16t^2 + vt + h(o)
h = -16(1.875)^2 + 60(1.875) + 5
h = -56.25 + 1112.5 + 5

Find the least number that, when multiplied by 504, will give a perfect cube
Answers
540 = 2 * 2 * 3 * 3 * 3 * 5
To make a perfect square, we need 3 * 5
So 15 is the number you want.
The least number that needs to multiply to 504 to make perfect cube is 49.
What is a perfect cube?A perfect cube of a number is a number that is equal to the number, multiplied by itself, three times. If x is a perfect cube of y, then x = y³.
The given number is 504.
Now,
504=2×2×2×3×3×3×7
= 2³×3³×7
To make perfect cube we need to multiply 49=7×7
That is, 2³×3³×7³
= 8×27×343
= 74088
Therefore, the least number that needs to multiply to 504 to make perfect cube is 49.

Write the formula for the sum of 7 consecutive numbers if the first number is m. \
Answers
Answer:
Step-by-step explanation:
If you have an odd number of consecutive numbers, the middle number should be x. So 7 of them would be written as
(x - 3)+(x - 2) + (x - 1) + x + (x + 1) + (x + 2) + (x+3)
That way all you are left with is 7x because the integers cancel.
That is not your question
You question is
Sum = m+(m + 1) + (m + 2) + (m + 3) + (m + 4) + (m + 5) + (m + 6)
Hello!
We can say what the formula is:
7m + 21Let's go?We need a formula to add 7 consecutive numbers, m being the first one.
So, we have:
m + (m + 1) + (m + 2) + (m + 3) + (m + 4) + (m + 5) + (m + 6)Now, let's simplify, joining the m and the numbers:
m + m + m + m + m + m + m + 1 + 2 + 3 + 4 + 5 + 6 = 7m + 21So, the formula is:
7m + 21.Let's go with an example?Let's say that m is 2. So, we substitute in the first non-simplified formula:
2 + (2 + 1) + (2 + 2) + (2 + 3) + (2 + 4) + (2 + 5) + (2 + 6) 2 + 3 + 4 + 5 + 6 + 7 + 8 = 35Now, we put it in the simplified formula, and it should give the same result:
7 × 2 + 21 14 + 21 = 35
It was confirmed. We conclude, once again, that the formula is:
