Answer:

see explanation

Step-by-step explanation:

Inequalities of the type | x | > a always have solutions of the form

x < - a or x > a, thus

2x + 1 < - 5 OR 2x + 1 > 5 ( subtract 1 from both sides of both inequalities

2x < - 6 OR 2x > 4 ( divide both sides of both inequalities by 2 )

x < - 3 OR x > 2

What's the difference between j(x) and just X in j(x)=-2x+4 ??

DIA [1.3K]

J(x) is equivalent to Y. For example if you were to have a equation in slope intercept form it would be y=mx+b which can be written in the same way as your problem j(x)=mx+b. To sum it up j(x) is just another way to say y=

A slide 5.4 meters long makes an angle of 29° with the ground. How far above the ground is the top of the slide? a. 2.52 m c. 4.

sdas [7]

With these questions, the best approach is to draw a diagram to represent the question. Draw a right angle triangle with an angle of elevation 29 degrees (make sure to label the angle that meets the base and hypotenuse as 29 degrees).

From here, we say that the hypotenuse is the slide itself, which is 5.4 metres. Using basic trigonometric ratios, we can deduce that:

sin(29) = x/5.4
x = 5.4sin(29) which is approximately 2.62 metres.

Answer:

One solution -> x = 35 , y = -25

Step-by-step explanation:

Solve the following system:

{14 x + 7 y = 315 | (equation 1)

16 x - 2 y = 610 | (equation 2)

Swap equation 1 with equation 2:

{16 x - 2 y = 610 | (equation 1)

14 x + 7 y = 315 | (equation 2)

Subtract 7/8 × (equation 1) from equation 2:

{16 x - 2 y = 610 | (equation 1)

0 x+(35 y)/4 = (-875)/4 | (equation 2)

Divide equation 1 by 2:

{8 x - y = 305 | (equation 1)

0 x+(35 y)/4 = -875/4 | (equation 2)

Multiply equation 2 by 4/35:

{8 x - y = 305 | (equation 1)

0 x+y = -25 | (equation 2)

Add equation 2 to equation 1:

{8 x+0 y = 280 | (equation 1)

0 x+y = -25 | (equation 2)

Divide equation 1 by 8:

{x+0 y = 35 | (equation 1)

0 x+y = -25 | (equation 2)

Collect results:

Answer: x = 35 , y = -25

Answer:

cos S = $\frac{7}{25}$

Step-by-step explanation:

this is a 7- 24- 25 right angle with RS = 7 , then

cos S = $\frac{adjacent}{hypotenuse}$ = $\frac{RS}{QS}$ = $\frac{7}{25}$
