Three students were given the expression 2 - 7(3x – 4) to simplify
Use the drop-down menus to complete the statements about whether each student's
answer is an equivalent expression.
Then choose an expression that is equivalent
Answer:
Tessa's expression is false because -7 times -4 is positive 28, not -28.
Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)
Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.
2-21x+28
The equivalent expression for the given expression is 2-21x+28.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
Tessa:
2-7(3x-4)=2-21x-28
Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.
Bernette:
2-7(3x-4)=-5(3x-4)
Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4
Lucy:
2-7(3x-4)=2-21x+28
Lucy's equivalent expression is correct.
Therefore, the equivalent expression is 2-21x+28.

Find the measures of the indicated angles pictures included!!!
Answer:
25
Step-by-step explanation:
The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

i need help algebra
Answer:
A. the slope value is 1/4
B. 0
C. y = 1/4x
Step-by-step explanation:
A: the slope can be calculated with the formula
[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]
m is the slope
(x1, y1) is your first coordinate point (any point will work)
(x2, y2) is your second coordinate point (any point will work)
Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - 0}{4 - 0} = \frac{1}{4} [/tex]
B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.
C:
the equation of the graph is y = mx + b.
m is the slope = 1/4
b is the y-intercept = 0
Therefore the equation is y = 1/4x

How much sugar does Patrick have left?
Answer:
7/30
Step-by-step explanation:
5/6-3/5 ,the LCM of denominators 6 and 5 is 30 ,6 denominator divided by 30 the result from the LCM times 5 the numerator is =25, 5 denominator divided by 30 the result from the LCM times 3 is =18 ,then subtract 25 from 18 giving you 7 ,then 7/6 or seven divided by six is one whole number, one over six
determine b so that the line with equation 5x + by - 6 = 0 is perprdicular to the line with equation 7y = 4x + 7
9514 1404 393
Answer:
b = 20/7
Step-by-step explanation:
The slope of the first line can be found by solving for y:
by = -5x +6 . . . . . . add 6-5x
y = -5/b +6/b . . . . . divide by b
The slope is -5/b.
The slope of the second line can be found by solving for y:
7y = 4x +7
y = 4/7x +1 . . . . . . divide by 7
The slope is 4/7.
For the lines to be perpendicular, the product of these slopes must be -1:
(-5/b)(4/7) = -1
-20/(7b) = -1 . . . . simplify
b = 20/7 . . . . . . . multiply by -b
The lines will be perpendicular when b = 20/7.

What is the solution
y=-x+2
y=-3x-2
Answer: (-2, 4)
Concept:
There are three general ways to solve systems of equations:
Elimination: using addition/subtraction to cancel out variables.Substitution: when two variables appear in both equations and are isolated, they could substitute each other.Graphing: graph the equations to find the intersection for the solution.Here we are going to use substitution since the variable [y] is being isolated in both equations.
Solve:
Given equations
y = -x + 2
y = -3x - 2
Using the method of substitution to combine the equations
-x + 2 = -3x - 2
Add 3x on both sides
-x + 2 + 3x = -3x - 2 + 3x
2x + 2 = -2
Subtract 2 on both sides
2x + 2 - 2 = -2 - 2
2x = -4
Divide 2 on both sides
2x / 2 = -4 / 2
[tex]\boxed{x=-2}[/tex]
Find the y value
y = -x + 2 →→→ Given expression
y = -(-2) + 2 →→→ Substitute values into the expression
y = 2 + 2 →→→ Simplify the value
[tex]\boxed{y=4}[/tex] →→→ SImplify by addition
