Answer:
Option 3 (79−3x=12x+19)
Step-by-step explanation:
When replacing x with 4 you will get the answer 67 = 67, which is true! The other three options are not true when replacing x with 4.
Equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.
Given that, the equations that have {4} as its solution set.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
1) Solution of an equation 5 + 2x = 3x + 3 is
3x-2x=5-3
⇒x=2
2) Solution of an equation 7−x=12x is
7−x=12x
⇒12x+x=7
⇒13x=7
⇒x=7/13
3) Solution of an equation 79−3x=12x+19 is
12x+3x=79-19
⇒15x=60
⇒x=4
4) Solution of an equation x²+3=10x−21 is
x²+3=10x−21
⇒ x²-10x+24=0
⇒ x²-6x-4x+24=0
⇒ x(x-6)-4(x-6)=0
⇒ (x-6)(x-4)=0
⇒ x=6 or 4
Therefore, equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

120
4=?
7=210 then cris cross the answer is 120
Suppose that Jane's height is x cm thus we have :
[tex] \frac{x}{210} = \frac{4}{7} \\ [/tex]
[tex]x = \frac{210 \times 4}{7} \\ [/tex]
[tex]x = 120[/tex]

For questions #9 - 11 "finding the slope" of a linear (straight) line, recall the "tools" that we can use:
1) Given a Graph: Slope or "m" = rise/run from one (x, y) point to a second (x, y) point on the line
2) Given any two (x, y) points on the line: Slope or "m" = y2 - y1 / x2 - x1
3) Given a "Table of Values": Choose any two (x, y) points in the table, then calculate the slope using the slope formula - Slope or "m" = y2 - y1 / x2 - x1

Kevin is creating a target for a game that will be played at the school's carnival and needs to put red tape in the shape of an "x" as shown below. If the area of the square board is 25 square feet, how many feet of tape will he need?
Answer:Kevin need 14.14 feet of red tape
Step-by-step explanation:
Given: (Figure Attached)
Area of Square = 25 square feet
As we know
Area of square = length x width = a x a = 25
a * a = 25
a = ±5 by taking square root both sides
It means a = 5 as the length can not be negative
Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,
By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.
=
=
x = ± 7.07 It means x = 7.07
Now the total tape required is 2 * x = 2*7.07 = 14.14
(help asap!) What is the value of the function at x = 2?
Enter your answer in the box.
Answer:
f(2) = -3
Step-by-step explanation:
Given the graph of a negative-sloped function:
In order to determine the value of a function given that x = 2, simply locate the x-coordinate of 2 in the graph, and find its corresponding y-coodinate. Doing so will provide you the corresponding output value of y = -3. Therefore, the value of the function at x = 2 is f(x) = -3, or f(2) = -3.

= 35/100 × $347.25
= $121.54
Thus, The sale price = $347.25 - $121.54
= $225.71

The expanded form of the given decimal number is 5+0.4+0.03+0.007.
What is expanded from of a decimal number?Unlike whole numbers, decimal numbers can also be written in the expanded form. For writing the decimals in expanded form, we multiply each of the decimal digits with increasing exponent values of (1/10).
The given decimal is 5.437
Now, the expanded form is
5+4/10+3/100+7/1000
= 5+0.4+0.03+0.007
Therefore, the expanded form of the decimal 5.437 is 5+0.4+0.03+0.007.
