Answer:

x = 4

Step-by-step explanation:

To begin, first find Angle SUT.

Knowing that SUH is a straight line, Angle SUT plus 100 degrees should equal 180 degrees. Angle SUT is 80 degrees.

The sum of all the degrees in a triangle is also 180 degrees.

(4x + 4) + (21x - 4) + 80 = 180

25x + 80 = 180

25x = 100

x = 4

M(4, 2) is the midpoint of . The coordinates of S are (6, 1). What are the coordinates of R? (8, 0) (2, 3) (1.5, 3) (5, 1.5)

faltersainse [42]

Assuming M is midpoint of RS

the midpoint formula is

x term of the midpoint is average of the x value of the 2 points
y term of the midpoint is average of the y value of the 2 points

if R is (x,y)

S is (6,1)

x value of midpoint is 4
x value of S is 6
x value os R is x

so
average of x and 6 is 4,
(x+6)/2=4,
x+6=8,
x=2

y value of midoint is 2
y value of S is 1
y value of R is y

average of 1 and y is 2
(y+1)/2=2
y+1=4
y=3

the midpoint is (2,3)

Solve and write solution in interval notation 4(x+1)+3>x-5

soldi70 [24.7K]

Answer:

$\large\boxed{x\in\left(-\dfrac{13}{3},\ \infty\right)}$

Step-by-step explanation:

$4(x+1)+4>x-5\qquad\text{use the distributive property}\\\\4x+4+4>x-5\\\\4x+8>x-5\qquad\text{subtract 8 from both sides}\\\\4x>x-13\qquad\text{subtract}\ x\ \text{from both sides}\\\\3x>-13\qquad\text{divide both sides by 3}\\\\x>-\dfrac{13}{3}\to x\in\left(-\dfrac{13}{3},\ \infty\right)$

Charlie used a regression calculator to generate the

Firdavs [7]

Answer:

Answer below, let me know if it didn't make sense.

Step-by-step explanation:

I attached a picture of the scatterplot with a line connecting the points. There is a definite upside down u type shape, and it doesn't look close to a line at all, so linear is not a good choice.

an upside down u shape (or right side up u shape for that matter) is exactly what a quadratic is, or any polynomial if you do it right, but quadratic is the simplest, so let's go with that.
