-3(2x+7)=-51 what does x=

Mathematics
1 answer:
devlian [24]3 years ago
3 0

Answer:

x=5

Step-by-step explanation:

-3(2x+7)=-51

opening bracket in the left hand side

-3.2x+(-3).7=-51

-6x-21=-51

adding 21 on both sides

-6x=-51+21

-6x=-30

dividing both sides by -6

[tex]\frac{-6x}{-6}=\frac{-30}{-6}

x=5

Hence the value of x came out to be 5

What is the slope of a line that passes through the points (-5,-3) and (9,-6)
kipiarov [429]
To find the slope given two points, you need to subtract the two y values over the two x values
(-5,-3)  (9,-6)
-5 will be x1, and -3 will be y1. 9 will be x2, and -6 will be y2. You then need to put the numbers in the correct place in the equation.
y2-y1      -6-(-3)     -9
-------- =   -------- =  ----
x2-x1       9-(-5)     14
Now that we have the slope (-9/14) you can use one of the coordinates to find the value of b.
Let's use (9,-6).
-6=-9/14(9)+b
-6=-81/14+b
+81/14
b=-3/14
Your final equation is y=-9/15x-3/14

What conditions must hold for a probability distribution to be acceptable?
VashaNatasha [74]

A distribution of probabilities is a numerical means of describing all unique combinations and the probabilities for a provided random variable, and the further discussion can be defined as follows:

  • The distributions mean (average), basic difference, skewness, as well as courtesies, are among such factors.
  • A formula, table, or chart can show a probability distribution for discrete probability distribution X that providing \bold{p(x) = P(X=x)} for all x.
  • For just a discrete random variable, the probability assigns annual probabilities with only a countless multitude of unique x values.
  • <em><u>Each result is likely to be between 0 and 1, including.</u></em>

Therefore, the final choice is "Option A".

The equation of a circle is given below. x ^2 +(y-2.25)^2 =196/169. What is the center? What is the radius?
yuradex [85]

Answer:

center : (0, 2.25)

radius: 14/13

Step-by-step explanation:

x^2+(y-2.25)^2=196/169

Rewrite x^2+(y-2.25)^2=196/169

(x-0)^2+(y-2.25)^2=(14/13)^2

c=(0,2.25),r= (14/13)

hope this helps<3
