If this the midpoint and st=x+3 and tu=4x-6 what is st and su

Mathematics

iragen [17]3 years ago

Answer:

st = 6

su = 12

Step-by-step explanation:

t is the midpoint of line segment su.

st = x + 3

tu = 4x - 6

Since, t is the midpoint of su, it should divide su into two equal parts. This means, measure of st and tu would be equal. So,

st = tu

x + 3 = 4x - 6

3 + 6 = 4x - x

9 = 3x

x = 3

st = x + 3 = 3 + 3 = 6

tu = 4x - 6 = 4(3) - 6 = 6

su = st + tu = 6 + 6 = 2(6) = 12

So, the measure of st would be 6 units and measure of su would be 12 units.

SpyIntel [72]

Answer:

No, none of the number need to be 48 for the mean to be 48. To get a mean, you add up all the number and divide it by the amount of numbers.

Example:

the mean of 10, 79, 42, 88, 19, and 50 is 48, but the actual number 48 was not part of the set.

10 + 79 + 42 + 88 + 19 + 50 = 288

288 ÷ 6 = 48

Hey!

------------------------------------------------

Points:

(-2, 3) and (3, 0)

------------------------------------------------

Find the slope:

= \frac{y2 - y1}{x2 - x1} \\=\frac{0 - 3}{3 - (-2)}\\= \frac{-3}{5} or -0.8

------------------------------------------------

Slope Intercept Form:

y = mx + b

m = slope

b = y-intercept

Slope = -3/5

Y-intercept = 9/5

Answer: y = -3/5 + 9/5

------------------------------------------------

Point Slope Form:

y - y1 = m(x - x1)

You can use either of the points.

Answer:

y - 3 = -3/5(x - 2)

          or

y - 0 = -3/5(x - 3)

------------------------------------------------

Hope This Helped! Good Luck!

• Mother has 40 guavas to share among her daughters, Naomi got 3
scoray [572]

Answer:

Step-by-step explanation:

As given Total Guavas  = 40 ,

3 daughters,

Let   share of Sharon = x

then by given condition ,

Naomi share = x+3                  (3 more then Sharon

Also Kassie share = x+3+10 =x+13     (10 more then Naomi

Now

total shared = total

Naomi + Sharon + Kassie = 40

(x+3) +(x) +(x+13) =40

adding like terms with like we get ,

3x+16=40

3x=40-16

3x=24

x= 24/3

x= 8  

hence Sharon share = x =8

Naomi share = x+3 =8+3 =11

Kassie share = x+13 = 8+13 = 21
