5 0

Step-by-step explanation:

<u>Our function:</u>

y = 3(x + 2)^{2}  + 7

<u>Include the exponent:</u>

y = 3(x^{2}  + 4) + 7

<u>Use the Distributive Property:</u>

y = 3 {x}^{2}  + 12 + 7

<u>Add:</u>

\boxed{y = 3 {x}^{2}  + 19}

Write an expression that is equivalent to three over four (5z+ 16). WILL GIVE BRAINLIEST
Alik [6]

Answer:

15 over fourz +12

Using the distributive property, 3/4 • 5z equals 15/4z, which can't be simplified. Then 3/4 of 16 is 12. If you divide 16 by 4 (the denominator) and then multiply by 3 (the numerator) that yields your answer.

Step-by-step explanation:

literally just got asked this question (if that makes sense lol)

so B is your answer

Which graph represents a line with a slope of and a y-intercept equal to that of the line y = x – 2? HELP!!!!!!!!!!!!!!!!!!!!!!!
Arlecino [84]
None of the graphs have a slope and y-intercept equal to y = x - 2.

y = x - 2 has a slope of 1 and y-intercept of -2, none of the graphs you shown have a slope of 1.

30. Felipe va a hacer un banderín para su equipo de fútbol, con las medidas que se indican en la figura. ¿Cuánta tela ocupará pa
blagie [28]

Veremos que el area del banderín es 930cm^2, entonces la opción correcta es A.

<h3>¿Que area tiene el banderin?</h3>

Luego de una pequeña busqueda online, pude ver que el banderin es un triangulo isósceles con base de 31cm y altura de 60 cm.

Recordar que para un triangulo de base b y altura h, el area es:

A = b*h/2

Entonces el area del banderín va a ser:

A = (31cm)*(60cm)/2 = 930cm^2

Entonces la opción correcta es A.

Arati posted a comment on her blog. Each day the number of responses to her comment was 125% of the number she received on the p
zvonat [6]

If the next number is 125% of the previous number, that means that the previous number is increasing by 25% each time.

The multiplier for increasing by 25% is:

(100 + 25) ÷ 100 = 1.25

So on day one, there are 64 responses. That means on day two, there will be:

---> 64 x 1.25 = 80 responses

On day 3, there will be:

---> 80 x 1.25 = 100 responses

Finally, on <u>day 4</u>, there will be:

---> 100 x 1.25 = 125 responses

A quicker way of getting this would be to do:

64 x 1.25³      since you are multiplying by 1.25  3 times

--------------------------------------------------

Answer:

125 responses
