PLEASE HELP!!!!!
i know my equation is y=2x+5
what graph is it?
Answers
Answer: D
Step-by-step explanation:
Since the line is y = 2x + 5
We know that one point is the y-intercept (0, 5)
If we plug in another point into the equation we should be able to determine the graph
when x = 4;
y = 2(4) + 5
y = 13
so another point is (4, 13)
D is the graph that has both the point (0, 5) and (4, 13)

Answer:
see attached
Step-by-step explanation:
Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change) and "rise" (vertical change) between the marked points.
In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.
The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.
If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)

If the weight of hardcover version is double the weight of paperback version then weight of hardcover version is 2.8 pounds and the weight of paperback version is 1.4 pounds.
What is equation?
An equation is a relationship between variables in equal to form. It is evaluated to find the values of variables.
How to solve an equation?
The weight of hardcover book is h
The weight of paperback version is p.
According to question:
h=2p (weight of hardcover version is double the weight of paperback version)
h+ p= 4.2 (weight of hardcover version and weight of paperback version is equal to 4.2 pounds)
Put the value of h=2p in h+ p=4.2
2p+p=4.2
3p=4.2
p=1.4
Put the value of p=1.4 in h=2p to get the value of h
h=2p
=2*1.4
=2.8
Hence the weight of hardcover version is 2.8 pounds and the weight of paperback version is 1.4 pounds.

A composite number can be divided evenly by a number that is not itself or 1
Neither would be 1 and negative numbers, as 1 only has one factor (itself) and the terms prime and composite do not include negative numbers.
9 is perfectly divisible by 3 so it is composite.
Answer:
9 has the following factors: 1,9,3
Thus, it is composite

To solve the quadratic equation 4x^2 + 20x = -29 using the quadratic formula, we can first rearrange the equation to bring all terms to one side:
4x^2 + 20x + 29 = 0
Now we can identify the coefficients a = 4, b = 20, and c = 29 in the general quadratic equation ax^2 + bx + c = 0. Applying the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
Substituting the values for a, b, and c into the quadratic formula:
x = (-(20) ± √((20)^2 - 4(4)(29))) / (2(4))
Simplifying further:
x = (-20 ± √(400 - 464)) / 8
x = (-20 ± √(-64)) / 8
x = (-20 ± 8i) / 8
Now, we can simplify the expression:
x = -20/8 ± (8i)/8
x = -5/2 ± i
Therefore, the roots of the given quadratic equation are:
x = -5/2 + i
x = -5/2 - i
B. p – 8; p ≠ –4
C. –p – 8; p ≠ –4
D. p + 8; p ≠ –4
Answers
The expression is:
Since the the divisor cannot be zero, that means that p+4 cannot be zero:
p + 4 ≠ 0
⇒ p ≠ -4
Let's simplify this expression:
Now, cancel out (p+4) and you will get:
and p must not be equal to -4
