3х + y = 8
x - Зу = 11

Answers

Answer 1

Answer:

y = 8-3x and y = -11/3 + x/3

For the first equation you have to subtract 3x from both sides of the equation. for the second equation you have to move all terms that doesn't contain y to the right side and solve

5. tan(30) =4/g

g = 4/tan(30)

g = 4√3

sin(30) = 4/h

h = 4/sin(30)

h = 8

6.

tan(30) = 14/l

l = 14/tan(30)

l = 14√3

sin(30) = 14/m

m = 14/sin(30)

m = 28

7.

sin(30) = j/50

j = 50 x sin(30)

j = 25

cos(30) = k/50

k = 50 x cos(30)

k = 25√3

The scale on a map is 1 cm:60 km. How many kilometers are represented by 2.5 centimeters on the map?

120 kilometers
105 kilometers
135 kilometers
150 kilometers

Answers

Answer:

150 km

Step-by-step explanation:

The scale tells you what real distance corresponds to a distance in the drawing. 1 cm in the drawing means 60 km of real distance.

Since 2.5 cm is 2.5 times 1 cm, it represents 2.5 times 60 km of real distance.

2.5 * 60 km = 150 km

Answers

Answer:

It has no slope because x 2 minus x 1 in the formula m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction is zero, and the denominator of a fraction cannot be zero.

Step-by-step explanation:

Points:

(7, 10) and (7, 20)

Slope-intercept form:

y= mx+b

Slope is:

m= (y2-y1)/(x2-x1)= (20-10)/(7-7)= 10/0,

denominator of the fraction is zero, we can't divide by zero, so this line has no slope

Examine the following gizmo problem and choose the best answer

Answers

Answer:

C. The answer is correct

Step-by-step Explanation:

One of the rules that applies when simplifying radical expressions, is that, only like radicals can be added together or subtracted from each other. In other words, the radicand, which is the number inside the "√" must be the same for two or more radicals to be added together or subtracted from each other.

In the expression given in the question, step 1 and step 2 are correct, as well as the final answer.

The final answer is correct because only like radicals can be added as 3√19 and 8√38 are unlike radicals. Their radicands, √19 and √38, are not the same, hence, the radicals do not need to be added.

The answer "3√19 + 8√38" is correct.

If f(x) = x^2 - 2x and g(x) = 6x + 4, for what value of x does (f + g)(x) = 0?

Answers

Answer:

x = -2

Step-by-step explanation:

[tex]f(x) =x^2 -2x\:\: and \:\: g(x) = 6x + 4\\(f+g)(x) = f(x) + g(x) \\(f+g)(x) = x^2 -2x+ 6x + 4\\(f+g)(x) = x^2+4x + 4\\(f+g)(x) = (x+2)^2\\ 0 = (x+2)^2...[\because (f+g)(x) =0]\\0 = x+2\\\therefore x = -2[/tex]

Answer:

x = -3 + √5 and x = -3 - √5

Step-by-step explanation:

Combine f and g:

f = x^2  -2x

+g =        6x  + 4

-------------------------

(f + g)(x) = x^2 + 6x + 4

Set this result = to 0 and solve for x:

By completing the square, we get:

y = x^2 + 6x + 9 - 9 + 4, or

y = (x + 3)^2 - 5 = 0

Thus, (x + 3)^2 = 5, and:

x + 3 = ±√5, or

x = -3 + √5 and x = -3 - √5

What is the decay factor in y = 760(0.75)3?

Answers

Decay factor is 0.75.

Step-by-step explanation:

The given function is

The general form of exponential decay function is  

[tex]y=a(1-r)^t[/tex]    ...(2)

where, a is initial amount, t is the time period, r is decay rate and (1-r) is the decay factor.

On comparing (1) and (2), we get

Therefore, the decay factor is 0.75.
