Answer:

I dont know what your supposed to do but i can tell you that x = 5 because if you simplify the equation you get 3x + 5 = 4x. Using this you can infer that a single x is equivalent to 5 since you need 5 to get from 3x to 4x.

The table shows the heights of 40 students in a class.

Darya [45]

Answer

A. 129.3

B. The students ages can be any number within the ranges, so having the middle number wont represent the other possible heights.

Step by step

'h' is the number between the surrounding number, the first would be 122.

You need to multiply the hight by frequency of each one,

122x7 =854

126x8=1008

130x13=1690

134x9=1206

138x3=414

Add them up = 5172

5172/40 =129.3

Select the correct answer. Which point lies on a circle with a radius of 5 units and center at P(6, 1)? A. Q(1, 11) B. R(2, 4) C

jasenka [17]

Answer:

T(9,-2)

Step-by-step explanation:

The circle has radius 5 units and center P(6,1).

The equation of this circle is

$(x-6)^2+(y-1)^2=5^2$

$(x-6)^2+(y-1)^2=25$

If Q(1,11) lies on this circle, then it must satisfy its equation.

$(1-6)^2+(11-1)^2=25$

$(-5)^2+(10)^2=25$

$25+100=25$ , this statement is false.

If R(2,4) lies on this circle, then it must satisfy its equation.

$(2-6)^2+(4-1)^2=25$

$(-4)^2+(3)^2=25$

$16+9=25$ , this statement is false.

If S(4,-4) lies on this circle, then it must satisfy its equation.

$(4-6)^2+(-4-1)^2=25$

$(-2)^2+(-5)^2=25$

$4+25=25$ , this statement is false.

If T(9,-2) lies on this circle, then it must satisfy its equation.

$(9-6)^2+(-2-1)^2=25$

$(4)^2+(-3)^2=25$

$16+9=25$ , this statement is TRUE.

The correct answer is D
