6 sweets cost 42p altogether how much do 8 sweets cost?

1 answer:

6 0

The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
Hope this helps :)

Graph the transformation of the figure.

yKpoI14uk [10]

This is pretty hard to answer completely because I can't graph it for you.

However, I can give you the coordinates by what the image provides.

For 7, there are 4 points:

(1, 4), (4, 4), (1, 1), (4, 1)

To translate, you can either look at it graphically or manually add/subtract numbers from the ordered pairs.

Remember that left/right applies to the x-coordinate and up/down applies to the y-coordinate:

(1-3, 4+4), (4-3, 4+4), (1-3, 1+4), (4-3, 1+4)

You get:

(-2, 8), (1, 8), (-2, 5), (1, 5)

Graph those and you'll get the translated rectangle.

Hope I helped :)

Find the value of "k" such that 1/2 is a root of 2x^2+11x=-k

trapecia [35]

The value of k is -6

Step-by-step explanation:

The general form of the quadratic equation is y = ax² + bx + c

The roots of the equation is the values of x when y = 0
ax² + bx + c = 0, is used to find the roots

∵ 2x² + 11x = -k

- Add k to both sides

∴ 2x² + 11x + k = 0

∵ The roots of the quadratic equations is the values of x when y = 0

∵ $\frac{1}{2}$ is a root of the equation

- Substitute x by $\frac{1}{2}$ in the equation above to find k

∵ 2( $\frac{1}{2}$ )² + 11( $\frac{1}{2}$ ) + k = 0

∴ 2( $\frac{1}{4}$ ) + $\frac{11}{2}$ + k = 0

∴ $\frac{1}{2}$ + $\frac{11}{2}$ + k = 0

- Add the like terms

∵ $\frac{1}{2}$ + $\frac{11}{2}$ = $\frac{12}{2}$ = 6

∴ 6 + k = 0

- Subtract 6 from both sides

∴ k = -6

The value of k is -6
