If f(x)=-5squared -4 and g(x) = -3x-2find (f+g)(x)
zloy xaker [14]

Answer:

-3x + 19

Step-by-step explanation:

f(x) = -5² - 4

f(x) = 25 - 4

f(x) = 21

(f+g)(x) = f(x) + g(x)

21 + -3x - 2

-3x + 19

AnnZ [28]

Answer:

169

Step-by-step explanation:

You should know that the middle number with the x is double the original number not in expanded form. You should also know that in the expanded form, the last number is the square of the original number. So square(26/2) = 169.

Which statement is true about figures ABCD and A'B'C'D?
Anika [276]

Answer:

Step-by-step explanation:

To understand the transformation better we will take a point B first.

Coordinates of B → (3, 0)

When we rotate this point by 180° counterclockwise about the origin, rule to be followed,

(x, y) → (-x, -y)

By this rule, coordinates of B'' will be,

B(3, 0) → B''(-3, 0)

Now we translate the point B by 2 units right.

Rule for the translation is,

(x, y) → [(x + 2), 0]

Following this rule,

B''(-3, 0) → B'[(-3+2), 0]

             → B'(-1, 0)

We can conclude with the statement, "Figure ABCD was rotated by 180° about the origin followed by the translation of 2 units to the right" to get the new figure A'B'C'D' similar to pre-image ABCD.

Two friends, Lucy and Lydia, had just bought their first cars. Lydia uses 3 gallons of gas to drive 114 miles in her car. The gr
alexandr402 [8]

Answer:

3.5 miles

Step-by-step explanation:

Lydia:

3 gallons of gas = 114 miles

We want to know how many miles a friend can travel on one gallon of gas, so we divide both sides by 3

1 gallon of gas = 114/3 miles = 38 miles

Lucy:

One point is

10x corresponds to 415y

10 gallons = 415 miles

divide both sides by 10 to get one gallon on a side

1 gallon = 41.5 miles

Lydia:

38 miles = 1 gallon

Lucy:

41.5 miles = 1 gallon

For 1 gallon, the difference is 3.5 miles, with Lydia having 3.5 miles less than Lucy.
