The slope is -3/2, I used points (0,6) and (4,0) but any points will get the same answer

Answer:

-1.5

Step-by-step explanation:

The answer in -1.5 because --

When you see the line segment going down it means that the slope is negative.

And if you see the plots on the line segment, you see that every other plot has two steady numbers Ex: (2,3) and then you see the other plots having a steady number and then a decimal Ex: (1, 4.5).

This means that the plots are taking up 1.5 or 1 $\frac{1}{2}$ squares.

Hope this helps ;3

A circle has a circumference of \blue{8}8start color #6495ed, 8, end color #6495ed. It has an arc of length \dfrac{32}{5} 5 32

maria [59]

Answer:

The central angle of the arc is 288 degrees

Step-by-step explanation:

The correct question is

A circle has a circumference of 8. It has an arc of length 32/5 . What is the central angle of the arc,in the degrees?

we know that

The circumference of the circle subtend a central angle of 360 degrees

uing a proportion

Find out the central angle for an arc of length 32/5

$\frac{8}{360^o}=\frac{(32/5)}{x}\\\\x=360(32/5)/8\\\\x=288^o$

A rectangular patio is 9 ft by 6 ft. When the length amd width are increased by the same amount, the area becomes 88 sq ft. Ging

SpyIntel [72]

( 6 + x)(9 + x) =88

54 + 15x + x^2 = 88

x^2 + 15x - 34 = 0

(x + 17)(x - 2) = 0
using zero product property:-
x + 17 = 0 or x - 2 = 0 giving:-

x = -17 , x = 2

x is the amount that the length and width are increased by.

x = -17 is negative and doesn't make sense in this context and can be ignored; so the amount of increase is 2 feet.

Consider the circle where QR = 7 units and UT= 4 units. What is the value of X, if x represents the length of segment ST? A. 15

julia-pushkina [17]

Option C:

x = 6 units

Solution:

QR = 7 units, RS = 5 units, UT = 4 units and ST = x

If two secants intersect outside a circle, the product of the secant segment and its external segment s equal to the product of the other secant segment and its external segment.

⇒ SR × SQ = ST × SU

⇒ 5 × (5 + 7) = x × (x + 4)

⇒ 5 × 12 = x² + 4x

⇒ 60 = x² + 4x

Subtract 60 from both sides.

⇒ 0 = x² + 4x - 60

Switch the sides.

⇒ x² + 4x - 60 = 0

Factor this expression, we get

(x - 6)(x + 10) = 0

x - 6 = 0, x + 10 = 0

x = 6, x = -10

Length cannot be in negative measures.

x = 6 units

Option C is the correct answer.
