What is the solution to this equation:
X+7=-8


Answers

Answer 1

Answer:

[tex]\boxed {x = -15}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]x + 7 = -8[/tex]

-Subtract both sides by [tex]7[/tex]:

[tex]x + 7 - 7 = -8 - 7[/tex]

[tex]\boxed {x = -15}[/tex]

So, the value of [tex]x[/tex] is [tex]-15[/tex].

Answer: y=-1/4x+3

Step-by-step explanation:

Answer:   y = (-1/4)x + 3

==================================================

Explanation:

y = mx+b is the general form of slope intercept equations

m is the slope, b is the y intercept

The y intercept is where the graph crosses the y axis. In this case it is at (0,3) so b = 3 is the y intercept

--------------------

The slope can be found through using the slope formula

m = (y2-y1)/(x2-x1)

m = (2-3)/(4-0)

m = -1/4

Or you could note that to go from (0,3) to (4,2) we must go down 1 and over to the right 4.

slope = -1/4 = rise/run

rise = -1 means we go down 1

run = 4 means we move to the right 4

--------------------

Since m = -1/4 and b = 3, we go from y = mx+b to y = (-1/4)x+3

4x+8=7.2+5x solve for x​

Answers

Answer:

[tex]\boxed {x = 0.8}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]4x + 8 = 7.2 + 5x[/tex]

-Take [tex]5x[/tex] and subtract it from [tex]4x[/tex]:

[tex]4x + 8 - 5x = 7.2 + 5x - 5x[/tex]

[tex]-x + 8 = 7.2[/tex]

-Subtract [tex]8[/tex] to both sides:

[tex]-x + 8 - 8 = 7.2 - 8[/tex]

[tex]-x = -0.8[/tex]

-Divide both sides by [tex]-1[/tex]:

[tex]\frac{-x}{-1} = \frac{-0.8}{-1}[/tex]

[tex]\boxed {x = 0.8}[/tex]

So, the value of [tex]x[/tex] is [tex]0.8[/tex].

The solution of the given expression is x = 0.8.

We are given that;

The expression 4x+8=7.2+5x

Now,

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

To solve for x, we can use the following steps:

- Subtract 4x from both sides: 4x + 8 = 7.2 + 5x - 4x - 4x

- Simplify: 8 = 7.2 + x

- Subtract 7.2 from both sides: 8 - 7.2 = 7.2 + x - 7.2

- Simplify: 0.8 = x

Therefore, by expression the answer will be x = 0.8.

Carly wants to buy some fish to keep in her room. At a local pet store customers can pay
$12.50 for a fish tank and $0.20 for each fish they purchase.
a. What is the slope or rate of change in the situation described? Explain.

Answers

Answer:

12.50

Step-by-step explanation:

Im not completely sure on this but the answer is 12.50 because it states that the price for a fish tank is $12.50. So im pretty sure that the intercept is that.

The Slope here is $0.20 which represent cost of each fish.

What is Rate of Change?

A rate of change is a rate that describes how one quantity changes in relation to another quantity.

Given that, Carly wants to buy some fish to keep in her room. At a local pet store, customers can pay $12.50 for a fish tank and $0.20 for each fish she purchased,

Let total cost be C, and total number of fish be n

According to question,

C = 12.50 + 0.20n

Hence, the slope 0.20 represents the change in total cost as the number of purchase of fish changes.

Answers

Answer:

Below in bold.

Step-by-step explanation:

f(x) = -x^2 + 10x - 17

Convert to vertex form by:

f(x) = -(x^2 - 10x) - 17

= - [(x - 5)^2 - 25] - 17

= -(x - 5)^2 + 25 - 17

=  -(x - 5)^2 + 8,

a. So axis of symmetry is x = 5.

b. Vertex is (5, 8) Max.

c.   Domain is All real x.

d. Range is (-∞, 8].
