What is the slope of a line that passes through the points (0,5) and (3,11)

1 answer:

8 0

The slope is the difference between the two y values over the difference of the two x values. 11-5=6, and 3-0=3, so 6/3 makes the slope 2

Answer the first word problem please! And show work

Travka [436]

Answer:

b= 9.17 ft

Step-by-step explanation:

The 4 feet from the wall is the bottom part of the triangle. The 10 ft. ladder is the hypotenuse of the triangle. Use the Pythagorean Theorem and substitute the known values.

a^2+b^2=c^2

4^2+b^2=10^2

Then square all the known values

16+b^2=100

Then get b by itself

b^2=-16+100

add -16 and 100

b^2=84

and finally square root both sides of the equation

b=9.16515 ft or 9.17 ft

Can someone answer 7-11 for me by 12:00AM

lawyer [7]

Answer:

Step-by-step explanation:

7). x + y = 4 ⇒ y = 4 - x -----> xy = - 96

x(4 - x) = - 96 ⇔ x² - 4x - 96 = 0

D = ( - 4)² - 4(1)(- 96) = 400 = (20)²

$x_{1}$ = (- ( - 4) - 20) ÷ 2(1) = - 8

$x_{2}$ = ( - ( - 4) + 20) ÷ 2 = 12

Numbers are - 8 and 12

8). It's your turn now. You can do it

9). x² - 5x + 3 = 0

0 < $x_{1}$ < 1

4 < $x_{2}$ < 5

10). - x² + 3x + 1 = 0

-1 < $x_{1}$ < 0

3 < $x_{2}$ < 4

11). x² + 2x - 2 = 0

- 3 < $x_{1}$ < - 2

0 < $x_{2}$ < 1

Answer:

Part a) The inequality that represent the situation is

$x+(3x)+(6x) \leq 350\ in$

Part b) The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$

Step-by-step explanation:

Let

x------> the length of the first wire

3x---> the length of the second wire

2(3x)=6x -----> the length of the third wire

Part a) WRITE AN *INEQUALITY* THAT MODELS THE SITUATION

we know that

The inequality that represent the situation is

$x+(3x)+(6x) \leq 350$

Part b) WHAT ARE THE POSSIBLE LENGTHS OF THE SHORTEST PIECE OF WIRE?

we know that

The shortest piece of wire is the first wire

Solve the inequality

$x+(3x)+(6x) \leq 350$

$10x \leq 350$

$x \leq 35\ in$

The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$
