What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(2x + 3) (x² + x - 2)
(2x)(x²) + (2x)(x) + (2x)(–2) + (3)(x²) + (3)(x) + (3)(–2)
2x³ + 2x² - 4x + 3x² + 3x - 6
2x³ + 5x² - x - 6
Thus,
The final expression is 2x³ + 5x² - x - 6.

What is the equation of the translated function? f(x) = (x – 1)2 – 5 f(x) = (x 1)2 5 f(x) = (x – 5)2 – 1 f(x) = (x 5)2 1
The equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5
What will be the equation?The vertex of the original function is (0, 0 )
The vertex of the translated function is (- 1, 5 )
Given f(x) then f(x + a) represents a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
The translated graph has been shifted 1 unit left, thus
f(x) = (x + 1)²
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
The translated graph has been shifted 5 units up,
Thus the equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5

R= d) -8, -7, -6, -5.
Which represents the distance between A(2, 3) and B(-1,-1)?
Answer:
5 units
Step-by-step explanation:
(x1, y1) =A(2,3)
(x2,y2) =B(-1,-1)
Using distance formula,
AB^2 = (x2-x1) ^2 +(y2-y1) ^2
=(-1-2)^2 +(-1-3)^2
=9+16
=25
Therefore, AB=5 units

Answer:
y=-4x-8
Step-by-step explanation:
use the equation y-y1=m(x-x1) and solve for y
Answer:
y=-4x-3
Step-by-step explanation:
For this, you would use the point-slope formula, which is (y-y1)=m(x-x1), with x1 and y1 being the coordinates from the ordered pairs, and m being the slope. You can plug the values from the problem into the formula:
(y-5)=-4(x+2)
y-5=-4x-8
y=-4x-3
hope this helps! :)
STEPS
1)
1. Write the coordinates of the 1st and
2nd points.
2. Label the coordinates of the first point
as
(X1,Y1) and the 2nd point as (X2
Y2).
3. Use the formula
m=Y2-Y
X2 - X
1st Point 2nd Point
1st Point:
2nd Point:
m=Y-Y
X2 - X
m=Y-Y
X2 - X
Answer:
The first point is right in the origin, so it's (0,0)
Our second point is (2, 1)
Our first point (0,0) would look like if labeled
0(X1) , 0(Y1)
Our second point would look like if labeled
2(X2) , 1(Y2)

Points X and Z are on a number line, and point Y partitions line XZ into two parts so that the ratio of the length of line segment XY to the length of line segment YZ is 1:4. The coordinate of X is 1.3, and the coordinate of Y is 3.8. What is the coordinate of Z?
Answer:
13.8Step-by-step explanation:
if Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;
XY/YZ = 1/4
cross multiply;
YZ = 4XY
Also, if The coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3
XY = 2.5
YZ = 4(2.5)
YZ = 10
Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y
coordinate of Z = 10+3.8
coordinate of Z = 13.8

If you add 10 grams of sugar into 30 grams of 20 % sugar syrup, you will make ____ grams of ____% sugar syrup.
Answer:
40 grams of 40% sugar syrup
Step-by-step explanation:
20% of 30 grams = 6grams of sugar
6 grams + 10 grams = 16 grams of 40% instead of 30 now
Therefore, 40g----------100%
16g-----------40%
Answer:
40 grams of 40% sugar syrup
Step-by-step explanation:
40 grams of 40% sugar syrup
30+10== 40 g
20% sugar in 30 = 1/5 of the syrup is sugar. = 6 g of sugar
6+10 = 16g of sugar in 40 grams of syrup.

What is a linear equation?A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
Let Q(t) represent the total number of boxes, and t is the time since noon in hours.
A warehouse contains 55 boxes, hence b = 55. At 3:30 pm (3.5 hours), the warehouse contains 90 boxes.
90 = 3.5m + 55
m = 10
The function that shows this situation is given by Q(t) = 3.5t + 55

Answer:
81%
Step-by-step explanation:
First, let's set up 3 equations:
w*0.6 = x
x*1.5=y
y*0.9=z
Now, we can substitute x in the second equation for w*0.6:
w*0.6*1.5 = y
Lastly, we can substitute y in the last equation for w*0.6*1.5:
w*0.6*1.5*0.9=z
w*0.81=z
Therefore, z is 81 percent of w.
