Nadia has £5 to buy pencils and rulers. Pencils are 8p each. Rulers are 30p each. She says “I will buy 15 pencils. Then I will b
guapka [62]

Answer:

Total pencils: 17

Total rulers: 15

Step-by-step explanation:

"I will buy 15 pencils."

15 * 8p = £1.20

15 pencils

"Then I will buy as many rulers as possible."

£5 - £1.20 = £3.80

£3.80/30p = 12 remainder 20p

12 rulers

"With my change, I will buy more pencils.”

20p/8p = 2 remainder 4 p

2 pencils

Total pencils: 17

Total rulers: 15

The table shows a linear function. Which equation represents the function?
4vir4ik [10]

Question is not complete and so I have attached the complete question.

Answer:

C: f(x) = -½x + 4

Step-by-step explanation:

Using slope formula between 2 points, we know that;

slope; m = (y2 - y1)/(x2 - x1)

Let's consider 2 points from the table;

(0, 4) and (-4, 6)

Thus;

m = (6 - 4)/(-4 - 0)

m = 2/-4

m = -½

Now using slope intercept form equation which is y - y1 = m(x - x1), we can find the equation of the function by picking on point say (0, 4).

Thus;

y - 4 = -½(x - 0)

y - 4 = -½x

y = -½x + 4

Thus;

f(x) = -½x + 4

Answer:

<h2>There are needed 3 burgers to reach the maximum measure of happiness of 25.</h2>

Step-by-step explanation:

The given function is

h(x)=-x^{2} +6x+16

Where x is the number of burgers and h the measure of happiness.

To find the maximum burgers needed to reach the maximum happiness, we just need to find the vertex of this function, which is defined as

V(h,k) where h=-\frac{b}{2a}, and b=6, a=-1, replacing these values, we have

h=-\frac{6}{2(-1)}=3

k=f(3)=-(3)^{2} +6(3)+16=-9+18+16=25

Therefore, there are needed 3 burgers to reach the maximum measure of happiness of 25.
