Solve the equation 9x2 + 8x - 5= 3x² to the nearest tenth

Mathematics
1 answer:
MArishka [77]2 years ago
5 0

Answer:

x=13

Step-by-step explanation:

9*2+8x-5=3x^2

9*2 = 18

18-5=13

13+8x=3x^2

3x^2 = 9x

13+8x=9x

   -8x -9x

13=x

x=13

For each linear equation write the slope of a line parallel to the given line. 3x - 2y = 8 ​
PSYCHO15rus [73]

We first need to convert 3x - 2y = 8 into y = mx + b form.

To do this, we first subtract 3x from

both sides and we have -2y = -3x + 8.

Now divide both sides by -2 and we have y = 3/2x - 4.

Now, we want the slope parallel to this given line.

Since the m or the coefficient of the x term

represents slope, we know this line has a slope of 3/2.

Now, it's important to understand that parallel lines have the same slope.

So the slope of the line parallel to this line will also be 3/2.

For the equation 8x + 2y = 16 What is the slope? What is the y-intercept (write as an ordered pair)? What is the x-intercept (wr
LiRa [457]

Answer:

y= -4x+16, (4,0), (0, 8)

Step-by-step explanation:

Let us rewrite the equation in slope intercept form, y=mx+b, where m is the slope:

2y= -8x+16

y= -4x+16

Therefore, -4 is the slope.

The x intercept can be found if we substitute 0 into the y:

0= -4x+16

4x=16

x=4

(4,0)

The y intercept can be found if we substitute 0 into the x:

2y= -8*0 +16

2y=0+16

2y=16

y=8

(0,8)

Please this due today i would love if you can help me
Sonja [21]

Answer:

I don't know if this what you want but I will explain how I think the answer is.

Step-by-step explanation:

a) You're at positive 5, and the integer explains that you're adding negative three spaces, which just means you go back three spaces. Your spot on the number line should be 2.

b) It says to go 3 spaces back from 5. Your spot on the number line will be two.

c) You're at negative 3, and you go another 5 spaces back. Your spot on the number line will be -8.

d) You're on -3 on the number line. You remove positive 5, so your new spot on the line is -8.

e) You're at -5. You're removing positive 3. Your going back three spaces. So you would be at -8.
