Answer:

<h2>The range: {-6, -10, -14, -18}</h2>

Step-by-step explanation:

Put the values of x from the domain to the equation of a function y = 4x - 2:

for x = -1

y = 4(-1) - 2 = -4 - 2 = -6

for x = -2

y = 4(-2) - 2 = -8 - 2 = -10

for x = -3

y = 4(-3) - 2 = -12 - 2 = -14

for x = -4

y = 4(-4) - 2 = -16 - 2 = -18

Could someone help me with this? Im lost

Talja [164]

A straight angle measures 180 degrees.

Angle x and the 150-degree angle form a straight angle.

x + 150 = 180

x = 30

Angle z and the 100-degree angle form a straight angle.

z + 100 = 180

z = 80

Now you know the measures of two angles of the three angles of the triangle. The sum of the measures of the angle of a triangle equals 180 degrees.

x + y + z = 180

30 + y + 80 = 180

y + 110 = 180

y = 70

Answer: x = 30; y = 70; z = 80

Here is a riddle:

lilavasa [31]

Answer:

The system of inequalities that represents this situation will be:

$f + s < 10$

$f - s > 3$

Step-by-step explanation:

Let 'f' represent the first number

Let 's' represent the second number.

Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.

so the inequality would be: f + s < 10

Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.

so the inequality would be: f-s > 3

Thus, the system of inequalities that represents this situation will be:

$f + s < 10$

$f - s > 3$

Answer:

Width = 9 cm, length = 14 cm

Step-by-step explanation:

Width = w; Length = L

2(W+L) = 46, W+L = 23, W= 23-L

W*L = 126, (23-L)*L = 126

W = 9, L = 14
