Answer:
[tex]= -2x^2 +4x+ 16[/tex]
Step-by-step explanation:
From the given equation:
[tex](x+ 2 ) \ and \ (-2x +8)[/tex]
As a single equation, we have:
[tex]= (x + 2) \ \times \ ( -2x + 8) \ = 0[/tex]
open brackets
[tex]\implies -2x^2 +8x +(-4x) + 16[/tex]
[tex]= -2x^2 +4x+ 16[/tex]

The sum of 8 times a number and 7 equals 3.
Answer:
8x + 7 = 3 (x = -0.5)
Step-by-step explanation:
I think this is the equation for what you said
If this is the right equation then x would equal -0.5
(hope this helps)
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
"The sum of 8 times a number (x) and 7 equals 3."
Let, "a number" = x
8x + 7 = 3
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
First, subtract 7 from both sides of the equation:
8x + 7 (-7) = 3 (-7)
8x = 3 - 7
8x = -4
Next, divide 8 from both sides of the equation:
(8x)/8 = (-4)/8
x = -4/8
x = -1/2
-1/2 is your number, or -0.5

The marked price of fan is Rs.1250, and the shopkeeper allows a discount of 6% on it . Find the selling price of the fan .
Given:;
Marked price of a fan = Rs. 1250.
Discount percent = 6%.
To find:
The selling price of the fan.
Solution:
We have,
Marked price of a fan = Rs. 1250.
Discount percent= 6%.
So,
Selling price = Marked price - Discount
[tex]S.P.=1250-\dfrac{6}{100}\times 1250[/tex]
[tex]S.P.=1250-75[/tex]
[tex]S.P.=1175[/tex]
Therefore, the selling price of the fan is Rs. 1175.

5x +9= -29
and
5x = -20
Are they equivalent
Answer:
No.
Step-by-step explanation:
We can try to simplify this by making sure the first equation has only the 5x on one side.
[tex]5x+9 =-29[/tex]
Subtract 9 from both sides.
[tex]5x = -38[/tex]
[tex]5x = -38[/tex] ≠ [tex]5x = -20[/tex]
They are not equal.

31.25/1.25= 25
total miles 25
Answer:
25
Step-by-step explanation:
sub 4.30 35.55 - 4.30 = 31.25
Divide 1.25 31.25/1.25 = 25
Final answer is 25

Triangle XYZ at X(–6,1), Y(4,0), Z(1,3) is reflected across the y-axis. What are the new coordinates of the triangle?
Answer:
X(6, 1), Y(-4, 0), Z(-1, 3)
Step-by-step explanation:
When reflecting an image across the y-axis, (i.e, across a vertical line at the position x = 0), All you need to do is negate the x coordinate of each point, so:
(-6, 1) becomes (6, 1)
(4, 0) becomes (-4, 0)
(1, 3) becomes (-1, 3)
Answer:
(6,1) (-4,0) (-1,3)

9514 1404 393
Answer:
x = 5y = 52Step-by-step explanation:
In any isosceles triangle, the base angles have the same measure:
y° = 52°
In any triangle the sum of angles is 180°.
52° +(14x +6)° +52° = 180°
14x = 70 . . . . . . . . subtract 110°, divide by °
x = 70/14 = 5 . . . . divide by the coefficient of x
The values of x and y are 5 and 52, respectively.

What is the solution to 3x+30+x=10+2x+5x+2?
The solution of the linear equation 3x + 30 + x = 10 + 2x + 5x + 2 will be 6.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
3x + 30 + x = 10 + 2x + 5x + 2
Simplify the equation, then we have
3x + 30 + x = 10 + 2x + 5x + 2
4x + 30 = 7x + 12
3x = 18
x = 6
The solution of the linear equation 3x + 30 + x = 10 + 2x + 5x + 2 will be 6.
