F(x) = 3x-7 and g(x) = -2x-6. Find (f o g)(4)

1 answer:

4 0

(f o g)(4) = f(g(4))
so
g(4) = -2(4) -6 = -14
f(g(4)) = 3(-14) -7 = -49

answer
 (f o g)(4) = -49

Reduce then calculate 7/8 x 4/15 x 3/7 = ? Can you help?

Zepler [3.9K]

since this is a multiplication, all the numerators are just factors of the product numerator and all denominators are just factors of the product denominator, so we can simply reorder them some, without changing the product.

$\bf \cfrac{7}{8}\times \cfrac{4}{15}\times \cfrac{3}{7}\implies \cfrac{7}{7}\times \cfrac{4}{8}\times \cfrac{3}{15}\implies \cfrac{1}{1}\times \cfrac{1}{2}\times \cfrac{1}{5}\implies \cfrac{1\cdot 1\cdot 1}{1\cdot 2\cdot 5}\implies \cfrac{1}{10}$

What is the distance between (-6,4) and (-8,6)? Choose 1 answer:

lukranit [14]

Answer:

Step-by-step explanation:

We want to find the distance between (-6, 4) and (-8, 6).

We can use the distance formula given by:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Let (-6, 4) be (x₁, y₁) and let (-8, 6) be (x₂, y₂).

Substitute:

$d=\sqrt{(-8-(-6))^2+(6-4)^2$

Evaluate:

$d=\sqrt{(-2)^2+(2)^2$

Evaluate:

$d=\sqrt{4+4}=\sqrt{8}$

Hence, our answer is D.

At maximum speed, an airplane travels 2,400 miles against the wind in 6 hours. Flying with the wind, the plane can travel the sa

Hatshy [7]

X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.

x + y = 2400/5 = 480 - flying with the wind

adding the 2 equations
2x = 880
x = 440

Speed of the plane with no wind = 440 mph
