Answer: D

Step-by-step explanation:

The graph is narrower, so the coefficient of $x^2$ has an absolute value more than 1.

Eliminate B and C.

Also, because g(x) opens down, the coefficient of $x^2$ is negative.

Eliminate A.

This leaves D as the answer.

Nady [450]

Answer:

The quantities used by Manuela were correct

Step-by-step explanation:

The question is

Did Manuela use the right quantities?

Let

x -----> the parts of oil

y ----> the parts of vinegar

we know that

The ratio of the parts of oil by the parts of vinegar of recipe is

$\frac{x}{y} =\frac{3}{1}\frac{oil}{vinegar}$

Determine the relation used by Manuela

$\frac{x}{y} =\frac{6}{2}$

Compare with the recipe

$\frac{3}{1} =\frac{6}{2}$

$3(2)=6(1)\\6=6$

Is true, the quantities are proportional

therefore

The quantities used by Manuela were correct

What is the range the 3rd side of the triangle can be be with 15 cm 14 cm ?

Volgvan

Answer:

20.5 cm

Step-by-step explanation:

I just used Pythagorean theorem in which c^2=a^2+b^2

so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm

The least common multiple of two whole numbers is 60. The ratio of the greater number to the lesser number is 6:5. WhAt are the

maks197457 [2]

Answer:

The two numbers are 12 , 10

Step-by-step explanation:

Given as :

The least common multiple of two numbers = LCM = 60

The ratio of the greater number to lesser number = 6 : 5

let the greater number = 6 x

And The smaller number = 5 x

∵ The LCM of numbers = 60

So, 6 × 5 × x = 60

Or, 30 × x = 60

∴ x = $\frac{60}{30}$

I.e x = 2

So The greater number = 6 x = 6 × 2 = 12

And The smaller number = 5 x = 5 × 2 = 10

Hence The two numbers are 12 , 10 Answer

X is 110% of 10, y% of 50 is 3.5

Dahasolnce [82]

Step-by-step explanation:

Set up a proportion.

x/10=110/100

x=11

Set up a proportion.

3.5/50=y/100

y=7

Helpppppppppppppppp ill mark you brainlist write in y=mx+b form

Alex Ar [27]

Answer:

I think: 0 = 3x + b or b = -3x + 0 or x = -b + 0/3 or 3 = -b + 0/x
