1.Which statement about the equation is true? x + 2 = x + 4 2. 5(w−1)−2=5w+7

Mathematics
1 answer:
Marysya12 [62]3 years ago
7 0

Answer:

Both equations have no solution.

Step-by-step explanation:

The first equation is:

x + 2 = x + 4

Group the similar terms to get:

x  - x =  4 - 2

0 =  - 2

This equation has no solution because

0 \ne - 2

The second equation is

5(w - 1) - 2 = 5w + 7

We expand the parenthesis to obtain:

5w - 5 - 2 = 5w + 7

5w - 7= 5w + 7

Group similar terms:

5w -5w = 7 + 7

0 = 14

This equation does not also have solution because

0 \ne14

Find the value of y.
olga nikolaevna [1]
Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles: 
\frac{x}{5} = \frac{16}{x}, \ then \ x= \sqrt{80}
2. according to the Pyphagorean theorem (in the smallest triangle):
y= \sqrt{ \sqrt{80^2} -5^2} = \sqrt{55}

answer: y=√55.

Question 29 of 40<br> Find f(-2) for f(x) = 5.3*.
blsea [12.9K]

Answer:

A. \frac{5}{9}

Step-by-step explanation:

To find f(-2) in f(x)=5*3^x, plug in -2 into all the x values.

f(-2)=5*3^-2, you can use calculator to calculate 3^-2 which equals 0.1, forever 1's.

f(-2)=5*0.1=0.5  Forever 5's.

f(-2)=0.5 or \frac{5}{9}

Hope this helps!

If not, I am sorry.

Question 4 of 10
ludmilkaskok [199]

Answer:

Option C. 3√3

Step-by-step explanation:

Please see attached photo for brief explanation.

In the attached photo, we obtained the following:

Opposite = a

Adjacent = 3

Hypothenus = 6

Angle θ = 60°

We can obtain the value of 'a' as follow:

Tan θ = Opposite /Adjacent

Tan 60° = a/3

Cross multiply

a = 3 x Tan 60°

But: Tan 60° = √3

a = 3 x Tan 60°

a = 3 x √3

a = 3√3

Therefore, the length of the altitude of the equilateral triangle is 3√3.
