Question #1:
Since it is unknown how much they paid for the original painting, we'll use x to represent that. 2x+1000 is equal to 55,000, so that is our equation.
2x+1000=55,000
2x=54,000
x=27,000
The Leungs originally paid $27,000 (answer choice B)

Question #12:
-4(x-11)=16
Apply the distributive property.
-4x+44=16
-4x=--28
x=7
Since x=7, let's figure out which answer choice can be possible by subsituting the x in each answer choice with 7.
Answer choice F: Does 7-11=4? No, so this answer can't be correct.
Answer choice G: Does 7-11=-4? Yes! This answer is correct.
Answer choice H: Does -28-11=16? No, so this answer can't be correct.
Answer choice I: Does -28+44=64? No, so this answer can't be correct.
It is answer choice G.

Helppppp Find the value of x. A. 176 B. 128 C. 256 D. 74

RSB [31]

Answer: Choice B) 128

Explanation:

We'll add up the given arc measures and then cut the result in half to get the angle formed by the intersecting chords (that subtend the arcs in question).

chord angle = (arc1+arc2)/2

x = (54+202)/2

x = 256/2

x = 128

Find the line y=a+bx which best approximates the data points

Vika [28.1K]

Answer:

y = 11.84x - 32.71

Step-by-step explanation:

Here, the given data points,

(−3,−70),(−1,−42),(1,−21),(2,−9),(4,14),

Let x represents the input value and y represents the output value,

So, the table that represents the given situation is,

x -3 -1 1 2 4

y -70 -42 -21 -9 14

By the above table,

$\sum x=3$

$\sum y=-128$

$\sum xy = 269$

$\sum x^2=31$

$\sum y^2 = 7382$

Let the equation of the line is,

y = bx + a

Where,

$a=\frac{\sum y \sum x^2 - \sum x\sum xy}{n(\sum x^2)-(sum x)^2}$

$b=\frac{n\sum xy - \sum x \sumy}{n(\sum x^2)-(\sum x)^2}$

n = number of data points = 5,

By substituting the values we get,

a = - 32.70547945 ≈ - 32.71,

b = 11.84246575 ≈ 11.84,

Hence, the equation of line would be,

y = 11.84x - 32.71

for every 300 kids in high school 2/3 of them take a language. What is the value of a number of students who dont take a languag

All you have to do is divide 300 hundred by 3 and you get 100 students that don’t take a language So 200 students take language and 100 students don’t take language
