The answer would be C 3d + 8 is less than or equal to 35.

The tank holds no more than 35, so there can be 35 fish in the tank so it can be equal to 35.

there is already 8 fish from the old aquarium and there are 3 new fish per day so the 3 gets the variable

Answer:

x = 39

y = 129

Step-by-step explanation:

to find x you do

x +51 = 90

subtract 51 from both sides

x = 39

to find y

we already know part of y is a right angle (90 degrees)

so we need to find the tiny other part

this tiny other part is equal to x

90 +39 = 129

A decorative steel is shown and it is made from circular circle and 6 stems.

STALIN [3.7K]

The total length of the steel used in the frame is 270 cm, if the decorative steel up of 6 stems and each stem is 45 cm.

Step-by-step explanation:

The given is,

Decorative steel made from circular circle of 6 stems

The length of the stem is 45 cm

Step:1

We need to find the total length of the steel used in the decorative steel,

Let, T - Total length of the steel

L - Length of the stem

n - Number of stems used in steel frame

Step:2

Formula to find the total length of the steel is,

$T=$ $l$ × $n$

From given,

$l$ = 45 cm

$n$ = 6 stems

Substitute the values in formula,

$T =$ ( 45 × 6 )

= 270

$T =$ 270 cm

Result:

The total length of the steel used in the frame is 270 cm.

The minimum of the graph of a quadratic function is located at (–1, 2). The point (2, 20) is also on the parabola. Which functio

ss7ja [257]

The min or max of a parabola/quadratic function is the vertex

for
y=a(x-h)²+k
the vertex is (h,k)

so
vertex/min is at (-1,2)
h=-1
k=2

y=a(x-(-1))²+2
y=a(x+1)²+2
find a
given, (2,20) is on the graph

20=a(2+1)²+2
20=a(3)²+2
20=9a+2
minus 2 both sides
18=9a
divide by 9
2=a

y=2(x+1)²+2 is da equation

3rd one
f(x)=2(x+1)²+2
