Three (3) consecutive integers is such that the largest is x. Write an expression
for the smallest.
Answers
Answer:
Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)
Step-by-step explanation:
Five times the smallest means 5x
Sum of the largest and five times the smallest means x+2+5x
This sum is -244 means x+2+5x=-244
Solve this equation
x+2+5x=-244
6x+2=-244
6x=-244-2
6x=-246
x=-41
So, smallest number is -41, second is -40 and largest is -39
You're answer is -39+5(-41)=244

if 10 calculator cost £120 how much does 8 cost?
Answers
Answer:
1 calculator cost £12
120 divided by 10 = 12
now 8 x 12 = £96
8 calculators cost £96
Step-by-step explanation:
Answer:
£96
Step-by-step explanation:
If you have 10 calculators which cost £120, you just need to divide 120 by 10 which will give you 12. Since 8 is only 2 away from 10, you just need to times 12 by 2, giving you 24, then take that away from 10! Hope this helped!

Step-by-step explanation:
A larger number is twelve more
than a smaller. Their sum is
84. Find the numbers.
Answers
Answer: bigger number is 48 and smaller number is 36
Step-by-step explanation:
Answer:
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48Step-by-step explanation:
Let the larger number be = xLet the smaller number be = yAs the larger number is twelve more than a smaller, so
x = y + 12
As the sum of larger and smaller numbers is 84, so
x + y = 84
now substituting x = y + 12 in th equation x + y = 84
x + y = 84
(y + 12) + y = 84
2y + 12 = 84
subtract 12 from both sides
2y + 12 - 12 = 84 - 12
2y = 72
divide both sides by 2
2y/2 = 72/2
y = 36
Thus,
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48how do you find the axis of symmetry?
Answers
Answer:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
Step-by-step explanation:
Answer:
x=-b/2a
Step-by-step explanation:
axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).
The expression to find vertex is -b/2a
Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.
