What’s the answer to this question?

lutik1710 [3]

Answer: B

Step-by-step explanation:

(f+g)(x) means f(x)+g(x). It is saying to add f(x) and g(x). Since we were given f(x) and g(x), we can directly add them together.

(f+g)(x)=4x+2+x²-6 [combine like terms]

(f+g)(x)=x²+4x-4

Now that we have found (f+g)(x)=x²+4x-4, the answer is B.

I need help with this V-4=v+2+7v-42 ??

zubka84 [21]

Answer:

$\boxed{\bold{v \ = \ \frac{36}{7}}}$

Step-by-step explanation:

Subtract v from both sides

$\bold{v-4-v=v+2+7v-42-v}$

Simplify

$\bold{-4=2+7v-42}$

Switch sides

$\bold{2+7v-42=-4}$

Group like terms

$\bold{7v+2-42=-4}$

Subtract the numbers: 2 - 42 = -40

$\bold{7v-40=-4}$

Add 40 to both sides

$\bold{7v-40+40=-4+40}$

Simplify

$\bold{7v=36}$

Divide both sides by 7

$\bold{\frac{7v}{7}=\frac{36}{7}}$

Simplify

➤ $\bold{v=\frac{36}{7}}$

It doesnt mean they are false it just means the person giving the study is going to favor something over something else in the study. Hes basically picking favorites.

Define the axis of symmetry, vertex, focus and directrix for

Papessa [141]

Answer:

see attached

Step-by-step explanation:

The equation is in the form ...

4p(y -k) = (x -h)^2 . . . . . (h, k) is the vertex; p is the focus-vertex distance

Comparing this to your equation, we see ...

p = 4, (h, k) = (3, 4)

p > 0, so the parabola opens upward. The vertex is on the axis of symmetry. That axis has the equation x=x-coordinate of vertex. This tells you ...

vertex: (3, 4)

axis of symmetry: x = 3

focus: (3, 8) . . . . . 4 units up from vertex

directrix: y = 0 . . . horizontal line 4 units down from vertex

(Can someone help me please?)

Scorpion4ik [409]

Answer:

Step-by-step explanation:

The answer is 10 because there are 20 days and no home work is due on 7 of those days so that’s 13 days with homework from math or writing. Then you take the three days where it was just math and subtract that to get 10 days of writing.
