Answer:

r=20

Step-by-step explanation:

The original equation: -8=-4-r/5

Add 4 to both sides: -4=-r/5

Multiply both sides by 5 to cancel out the fraction: -20=-r

Simplify: r=20

Let me know if this helps!

If anyone has a graphing calculator with them and can help me do these two problems<br> Algebra 1
katrin2010 [14]

Answer:

3a) y = -0.1x +26000

3b) $16500

4a) y = 8.2x - 16451.27

4b) 79.93

Step-by-step explanation:

3a) y = -0.1x +26000

3b) If the odometer reads 95000 we need to plug in that value for x: y = -0.1(95000) + 26000 = $16500

4a) y = 8.2x - 16451.27

4b) To estimate the number the rabbits in the year 2016, we need to plug in that value for x: y = 8.2(2016) - 16451.27 = 79.93 = 80 rabbits

Help me pleasee (10 points)
Montano1993 [528]

Answer:

B

Step-by-step explanation:

Givens

a^2 + b^2 = c^2

a = 4x

b = x + 2

c = 3x + 4

Solution

(4x)^2 + (x + 2)^2 = (3x + 4)^3                  Remove all the brackets.

16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16  Collect like terms on the left

17x^2 + 4x + 4 = 9x^2 + 24x + 16            Subtract the terms on the right

8x^2 - 20x - 12 = 0

This factors into

(4x - 12)(2x + 1)

There are 2 answers

4x - 12 = 0

4x = 12

x = 12/4

x = 3

or

2x + 1 = 0

2x = - 1

x = - 1/2

You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.

So the only answer is x = 3

Which two angles in the figure are obtuse angles?
ValentinkaMS [17]

Answer: C. ∠SQP and ∠TQR

Step-by-step explanation:

Since, by the given diagram,

m∠TQR  = m∠SQP (vertical angles)

And, m∠TQP < m∠TQR

By adding ∠TQR on both sides,

m∠TQP + m∠TQR < m∠TQR+m∠TQR

⇒m∠TQP + m∠TQR < 2 ∠TQR

⇒ 180° < 2 m∠TQR ( Because ∠TQP and ∠TQR are linear angles)

⇒ 90° < m∠TQR

Hence ∠TQR is a obtuse angle,

⇒  ∠SQP also is a obtuse angle.
