The given expression [-20 - (-4)] is equivalent to (-20 + 4).
What is a linear equation?A linear expression is an expression in which the highest power of the variable is always 1. If there is no variable, we can assume the power of the variable as 0.
Therefore, the variable x⁰ = 1.
Given linear expression:
-20 - (- 4)
= (-20 + 4)

Answer:
The length of TQ is 14.
Step-by-step explanation:
The length of SV and VS are the same.
4x - 1 = 15
4x = 16
x = 4
Similarly, the length of TS and TQ are the same.
3x + 2 = 3(4) + 12 = 14
Aaaaaa help I’m stuck at F I really need to do this so I could get a D please with explanation
Answer:
$1.51
Step-by-step explanation:
1.25 lb. of dried fruit : [tex]\frac{\$1.84}{lb.}*\frac{1.25\ lb.}{1}=\$2.30[/tex]
0.5 lb. of cereal : [tex]\frac{\$2.38}{lb.}*\frac{0.5\ lb.}{1}= \$1.19[/tex]
Cost = $2.30 + $1.19 = 3.49
Money = $5
$5 - $3.49 = $1.51 in change
Which of the following transformations is the only one that can change the lengths of its sides but remain similar??
A) Translation
B) Rotation
C) Reflection
D) Dilation
Answer:
D
Step-by-step explanation:
It is dilation because transformation is moving and sliding, rotation is spinning, reflection is a mirroring of the shape upon a certain line or axis, and dilation is the change in size leaving 1 point the same.

Find an equation of a line that is parallel to y = 5x + 9 and passes through
the point (3, 11).
Answer:
y = 5x - 4
Step-by-step explanation:
The equation y = 5x + 9 currently does not pass through the point (3, 11). It asks us to create the equation of a line parallel to y = 5x + 9. So all we have to change is the 9, where the line passes through the y-coordinate. The slope, 5x, has to stay the same, otherwise, the new line will not be parallel to y = 5x + 9.
The line has to pass through to point (3, 11). The 3, stands for the x value, and 11 the y value. If we start at the y value of -4, that means the very next point would be (1, 1), and the next one, (2, 6), and the final one, (3, 11). This is because we know the slope of the line is 5x, that means for every 1 gained x value, the y value gains 5 values.
So, the equation of the new line would be this:
y = 5x - 4

the graph below shows a quadratic function f(x) and an absolute value function g(x)
which of the following x-values are approximate solutions to the equation f(x)=g(x)? select all that apply
Answer:
The x-values that are approximate solution of the equation [tex]f(x) = g(x)[/tex] are [tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex], respectively.
Step-by-step explanation:
From graph we infer that the x-values that represents a solution to the system of equations corresponds to those values of x in which both functions coincide. As we see, there are two x-values for [tex]f(x) = g(x)[/tex], which are described below:
[tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex]
The x-values that are approximate solution of the equation [tex]f(x) = g(x)[/tex] are [tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex], respectively.
Find the sum and the product of the roots of the equation: x^2+35x−51=0
what is the product of them?
Answer:
(a)
[tex]Sum = -35[/tex]
[tex]Product = -51[/tex]
(b)
[tex]Product = 1785[/tex]
Step-by-step explanation:
Given
[tex]x^2 + 35x - 51 = 0[/tex]
Required
(a) Determine the sum and product of the equation
(b) Determine the products of the (a)
Solving (a)
The general form of a quadratic equation is:
[tex]ax^2 + bx + c = 0[/tex]
Where
[tex]Sum = -\frac{b}{a}[/tex]
[tex]Product = \frac{c}{a}[/tex]
By comparison of [tex]ax^2 + bx + c = 0[/tex] tp [tex]x^2 + 35x - 51 = 0[/tex]
[tex]a = 1[/tex]
[tex]b = 35[/tex]
[tex]c = -51[/tex]
So:
[tex]Sum = -\frac{b}{a}[/tex]
[tex]Sum = -\frac{35}{1}[/tex]
[tex]Sum = -35[/tex]
[tex]Product = \frac{c}{a}[/tex]
[tex]Product = \frac{-51}{1}[/tex]
[tex]Product = -51[/tex]
Solving (b)
From (a) above, we have:
[tex]Sum = -35[/tex]
[tex]Product = -51[/tex]
Their product is:
[tex]Product = -35 * -51[/tex]
[tex]Product = 1785[/tex]

y= 3x - 5 (x)
Answer:
y= 3x - 5
y+5 = 3x
x = (y+5)/3
Answer:
x = [tex]\frac{y+5}{3}[/tex]
Step-by-step explanation:
Given
y = 3x - 5 ( add 5 to both sides )
y + 5 = 3x ( isolate x by dividing both sides by 3 )
[tex]\frac{y+5}{3}[/tex] = x
