F(x) = x^2 - 3x+ 5 g(x) = 2x^2 - 4x - 11 what is h(x) = f(x) + g(x)
iogann1982 [59]

Hey there! :)

Answer:

h(x) = 3x² - 7x - 6

Step-by-step explanation:

Calculate h(x) by adding the two polynomials:

h(x) = f(x) + g(x):

h(x) = x² - 3x + 5 + 2x² - 4x - 11

Combine like terms:

h(x) = 3x² - 7x - 6

Plzzzzzx anyone help me
Yuki888 [10]

First look at the points and find their x and y values. So we have:

(-3,3), (0,0), (3,3)

Next separate the x values and the y values

x values: -3, 0, 3

y values: 3, 0, 3

The x values are your domain and the y values are are range

So the answer is b

PLEASE HELP!! URGENT!! WILL GIVE BRAINLIEST TO FASTEST ANSWER!! TAKING TEST ON EDGE 2020!!
Leto [7]

Answer:

expressions which represent exponential decay:

A. 900(0.05)^t

B. 700(0.9)^x

Step-by-step explanation:

Exponential decay functions has the next form:

y = ab^x

where b < 1

A. 900(0.05)^t , a = 900, b = 0.05, the variable is t instead of x. 0.05 < 1, then it represents exponential decay

B. 700(0.9)^x , a = 700, b = 0.9 < 1, then it represents exponential decay

C. 53(1.75)^(0.3x) =  53(1.75)^(0.3)(1.75)^x, a =  53(1.75)^(0.3), b = 1.75 > 1, then it doesn't represent exponential decay

D. 90(1.2)^t, a = 90, b = 1.2 > 1,  then it doesn't represent exponential decay. (the variable is t instead of x)

E. .300(2.4)^(1.2y)  = 300(2.4)^(1.2)(2.4)^y, a = 300(2.4)^(1.2),  b = 2.4 > 1, then it doesn't represent exponential decay. (the variable is y instead of x)

F. 2x² + 9 , this is a quadratic function,  then it doesn't represent exponential decay.

G. 18 – 3y, this is a linear function,  then it doesn't represent exponential decay.

Which of the following choices shows the equation solved for y
katen-ka-za [31]

Answer:

#1; y = -\frac{7}{2}x+5

Step-by-step explanation:

7x+2y=10

2y = -7x + 10

\frac{2y}{2} = -\frac{7x}{2} + \frac{10}{2}

y = -\frac{7}{2}x + 5
