Answer:
Solving [tex]7-3(4-2x)-10x[/tex] we get [tex]-4x-5[/tex]
Step-by-step explanation:
Jon solved:
7-3(4-2x)-10x
4(4-2x)-10x
16-8x-10x
16-18x
Error in John Work
The error in John work is that he subtracted 7-3 first, which is wrong. According to the rule, first brackets are solved, then multiplication or division and then addition or subtraction is performed.
Madison Solved:
7-3(4-2x)-10x
7-3(2x)-10x
7-6x-10x
7-16x
Error in Madison Work
The error in Madison work is that she subtracted (4-2x) and get 2x which is wrong. Only like terms are added or subtracted. 4 and -2x are not like terms so, we can't subtract them
Selina Solved:
7-3(4-2x)-10x
7-12-2x-10x
-7-12x
Error in Selina Work
The error in Selina work is that she wrongly multiplied -3 with -2x
-3(-2x) we get 6x but Selina found it to be -2x which is wrong.
My solution:
Now, we will solve the equation correctly
[tex]7-3(4-2x)-10x[/tex]
First, multiply -3 with terms inside the bracket
[tex]7-12+6x-10x[/tex]
Now, combine like terms
[tex]7-12+6x-10x\\-5-4x[/tex]
or we can write -4x-5
So, solving [tex]7-3(4-2x)-10x[/tex] we get [tex]-4x-5[/tex]

Answer:
y = 2^x
Step-by-step explanation:
The x-values are sequential integers, which helps the discovery of the function. The y-values have a common ratio of 2 = 2/1 = 4/2 = 8/4. This is the base for the exponential function.
The initial value of y=1 at x=0 tells you the multiplier of the exponential factor is 1, and the exponent is x (with no additions or subtractions). Your function is ...
y = 2^x
Write the equation of the line in slope-intercept form that passes through
the point (-3, 5) and is parallel to y = -2/3 x
Answers
Answer:
y= -2/3x+3
Step-by-step explanation:
Parallel lines have the same slope but different y-intercepts.
y=-2/3x is your original equation
Your slope is still -2/3
y=mx+b
y=-2/3x + b
Substitute the points from the coordinates
5 = -2/3(-3) + b
5 = 2 + b
-2 -2
b=3
Your parallel line equation is: y= -2/3x+3

On a number line point x is located at 2 / 3 on a second number line point y is the same distance from zero as point x what has a numerator of 8 what is the in denominator of y
Answers
Answer:
12
Step-by-step explanation:
Given that :
Point X on number line 1 from 0= 2/3
Point Y on number line 2 from 0 = same distance as point X on number line
Point Y has a denominator of 8 ; the numerator is thus;°
Let denominator = d ; Fraction becomes 8/d
Thus `
Point X on 1 = point Y
2/3 = 8/ d
2d = 3 * 8
2d = 24
d = 12
