How many solutions does this equation have?
–2 − 10z = –4 − 10z
Answer:
No solutions
Step-by-step explanation:
To find out how many solutions there are you must solve:
- 2 - 10z = - 4 - 10z
Add 10z to both sides:
-2 = -4
Since the two terms are different from one another, that means that there are no solutions for this equation.

what is the slope of the line 7x+2y=5
Answer:
slope = -7/2x
Step-by-step explanation:
you can solve the equation in order to make it slope-intercept form.
7x + 2y = 5
2y = -7x + 5
divide everything by 2
it becomes y = -7/2x + 5/2
The required slope of the line is m = -7 / 2.
A line can be defined by the shortest distance between two points is called a line.
Method 1
7x + 2y = 5
Rearranging the equation in the standard form of the equation of a line
y = mx + c
where m is the slope of the line and c is the intercept of the line.
7x + 2y = 5
2y = -7x + 5
y = -7x/2 + 5 - - - - - -(1)
Comparing equation 1 with the standard form of the equation
m = -7/2 and c = 5
Method 2
Differentiate the given equation, with respect to x
d/dx (7x + 2 y) = d/dx (5)
7 + 2dy/dx = 0
dy/dx = -7/2
Slope = dy/dx = -7/2
Thus, the required slope of the equation is m = -7/2

Two boats started to move towards each other from two boat stations, located 30 miles apart. One boat moved at a speed of 3 miles per hour, the other moved twice as fast. How soon will the boats meet?
Answer:
The boats will meet in 3.33 hours.
Step-by-step explanation:
The position of each boat can be modeled by a first order equation.
I am going to say that the first boat is at the position 0, and moving in the positive direction with a speed of 3 miles per hour. So
[tex]A(t) = 0 + 3t[/tex]
They are moving in oppositie directions, and initially are 30 miles apart. This means that the second boat starts at the position 30, and moves in the negative direction at the rate of 6 miles an hour. So
[tex]B(t) = 30 - 6t[/tex]
How soon will the boats meet?
This is t when:
[tex]A(t) = B(t)[/tex]
[tex]3t = 30 - 6t[/tex]
[tex]9t = 30[/tex]
[tex]t = \frac{30}{9}[/tex]
[tex]t = 3.33[/tex]
The boats will meet in 3.33 hours.

Francesca made a rug to go in her daughter's room. The length is 5 ft and the width is 8 ft. What is the perimeter AND area of the rug?
Perimeter:
Area:
Step-by-step explanation:
Length of the room is 5 ft and the width is 8 ft.
Perimeter is equal to the sum of all sides of the room.
The shape of room is rectangle.
The perimeter of rectangular room is given by :
[tex]P=2(L+B)\\\\P=2(5+8)\\\\P=26\ ft[/tex]
Area of a rectangular shaped room is given by :
[tex]A=L\times B\\\\A=5\times 8\\\\A=40\ ft^2[/tex]
So, the perimeter and area of the rug are 26 feet and 40 sq feet.
Mrs. Burdell's storage container is 3 feet long, 2 feet wide, and 8 feet tall. Can she fit 44 boxes that each has a volume of 1 cubic foot in her container? Explain your answer.
Answer:
Yes, she can fit 44 boxes if each has a volume of 1 cubic foot in her containerStep-by-step explanation:
If Mrs. Burdell's storage container is 3 feet long, 2 feet wide, and 8 feet tall, then the volume of the strorage container is expressed as shown;
Volume = Length *Breadth * Height
Volume of the container = 3*2*8 = 48ft³
If she each boxes she is to fit into the storage container has a volume of 1ft³, the total number of boxes she can fit into the container is expressed as:
Number of container = volume of the storage container/volume of a container
= 48ft³/1ft³
= 48 boxes
Since she can fit 48 boxes successfully in her storage tank, then she can fit 44 boxes as well into the storage tank since the total number of boxes the tank can take is greater tan the proposed amount of boxes in question.
So, yes she fit 44 boxes if each has a volume of 1 cubic foot in her container

The table shows the estimated number of bees, y, in a hive x days after a pesticide is released near the hive.
A 2-column table with 6 rows. The first column is labeled number of days with entries 0, 10, 20, 30, 40, 50. The second column is labeled estimated number of bees with entries 10,000; 7,500; 5,600; 4,200; 3,200; 2,400.
Which function best models the data?
y = 9,958(0.972)x
y = 0.972(9,958)x
y = 9,219x– 150
y = –150x + 9,219
Answer:
A
Step-by-step explanation:
y = 9,958(0.972)x
Function which best models the given data is -150x + 9219.
What is the solution of an equation?A solution is an assignment of values to the unknown variables that makes the equality in the equation true.
According to the given question
y represents the number of bees.
and, x represents the number of days.
Since, we have to find the function to represent the given data.
As, we know the given data are the solution of any function, so they must satisfy the function. For this we will take any value of x and y and check whether it satisfy the given function or not.
From the given data,
Let check for the point (0, 1000).
Substitute (0, 1000) in the given function one by one.
For, y = 9,958(0.972)x
At, x = 0
We get y = 0
⇒ ( 0, 1000) is not the solution of the function 9958(0.72)x
For, y = 0.972(9,958)x
At, x = 0
we get y = 0
⇒ (0, 1000) is not the solution for the function 0.972(9958)x
For, y = 9219x - 150
At x = 0
we get y = -150
⇒ (0, 10000) is not the solution of function, 9219x -150
For, y = -150x + 9219
At x = 0
y = 9219 which is nearly equals to 10000 because y is the estimated number of bees.
⇒ (0, 10000) is the solution of the given function y = -150x + 9219 .
Hence, the function which best models the given data is -150x + 9219.

find the measure of the angles indicated
Answer: 60º
Step-by-step explanation:
With respect to the line ZB, it makes an angle of 180º if measured using DZ. If the angle outside the triangle measures 140º, subtract from 180º to find the angle inside the triangle.
180º-140º=40º
So, now we have angle c=80º and angle b=40º, we can make an equation to find angles D which we'll call x.
The sum of the angles of a triangle must be equal to 180º.
80+40+x=180
120+x=180
x=180-120
x=60
Answer:
Find the measure of the angles indicated
∠CDB = 60°
Step-by-step explanation:
∠CBD + ∠CBZ = 180°
∠CBD + 140° = 180°
∠CBD = 180° - 140°
∠CBD = 40°
∠CBD + ∠BCD + ∠CDB = 180°
40° + 80° + ∠CDB = 180°
120° + ∠CDB = 180°
∠CDB = 180° - 120°
∠CDB = 60°

If one factor of x2 + 2x - 24 is (x+6), what is the other factor?
eOf
(x+8)
(x-8)
(x+4)
(x-4)
Answer:
(x - 4)
Step-by-step explanation:
Given
x² + 2x - 24
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (+ 2)
The factors are + 6 and - 4, since
6 × - 4 = - 24 and 6 - 4 = + 2, thus
x² + 2x - 24 = (x + 6)(x - 4) ← in factored form
Thus the other factor is (x - 4)
The solution is Option D.
The equation x² + 2x - 24 = 0 has the factors as ( x + 6 ) and ( x - 4 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
x² + 2x - 24 = 0 equation (1)
The equation can be factorized as
x² + 6x - 4x - 24 = 0
Taking x as the common factor , we get
x ( x + 6 ) - 4 ( x + 6 ) = 0
So , the equation will be
( x + 6 ) ( x - 4 ) = 0
Therefore , the factors of x are -6 and 4
Hence , the factors of the equations are ( x + 6 ) and ( x - 4 )
