Step-by-step explanation:

$S_{31} = 9 \cdot 31 + [-0.5 \cdot \frac{31(31-1)}{2}] = 46.5$

$S_{40} = 40 + [-3 \cdot \frac{40(40-1)}{2}] = -2300$

Landen spent L hours at the beach last weekend. Matéo spent 15% fewer hours at the beach than Landen did

fenix001 [56]

Answer: B, D, and E

0.85L

or

L-0.15L

or

L(1-0.15)

or

$L - \frac{15}{100}L$

$L - \frac{3}{20}L$

Step-by-step explanation:

L is the number of hours Landen spent at the beach. Mateo spent 15% less time. This means he spent 85% of it. So 0.85 times L. We can also calculate it by subtracting the difference between the two kids. - 15%. 15% is 0.15L or $\frac{15}{100}L$ . We subtract by L-0.15L or as $L - \frac{15}{100}L$ . This fraction can simplify to $L - \frac{3}{20}L$

Help and please explain so I can do it on my own. There are a couple more on this sheet.

Andreas93 [3]

Answer:

(2, -10)

Step-by-step explanation:

so first i find the axis of symmetry using the equation x= -b/2a

in this problem

a=3

b= -12

c= 2

- (-12)/ 2(3) = 2

2 will be the x point for your vertex

you then plug in your x point into the original equation and solve for y

y = 3(2)^2 - 12(2) +2

y = -10

Vertex is then (2, -10)
