Answer:
y=-5/7x-3
Step-by-step explanation:
so, we need the equation to be in y=mx+b form.
The equation right now is 5x+7y=-21 in standard form.
We need to isolate y onto one side
Here's the equation:
5x+7y=-21
subtract 5x from both sides
7y=-5x-21
divide by 7
y=-5/7x-21/7
simplify
y=-5/7x-3
Hope this helps! :)

The function below shows the revenue for t-shirt sales. For every $1 decrease in price, 5 more t-shirts can be sold.
Part A: What is the maximum of this graph and what does the maximum represent?
Part B: What is the y-intercept of the graph? what does it represent?
Part C: Does the graph have zerosolution(s)? If so, identify the zero and what it represents?
Answer:
Part A: The maximum of the graph is the highest point which is at (2.5, 2531.25). Since xx is the decrease in price and yy is the profit, the maximum of (2.5, 2531.25) means that the maximum profit is $2531.25 and occurs when the price of the t-shirts is decreased by $2.50.
Part B: The yy-intercept is when the graph intersects the yy-axis which occurs at about (0, 2500). The yy-intercept then means that the profit is $2500 if the price of the t-shirts does not decrease.
Part C: The solution of a graph is its xx-intercept(s). The graph crosses the xx-axis at (25,0) so this point is the solution. The solution means that the profit will be $0 if the price is decreased by $25.

Step-by-step explanation:
Triangle XYZ, X equals 27 cm, Y equals 79 cm and angle C equals 142Degrees. Find the length of Z, to the nearest centimeter.
Given:
In triangle XYZ, x = 27 cm, y = 79 cm and [tex]\angle C=142^\circ[/tex].
To find:
The length of z.
Solution:
In triangle XYZ, using the Law of cosine, we get
[tex]z^2=x^2+y^2-2xy\cos Z[/tex]
Putting the given values in the above formula, we get
[tex]z^2=(27)^2+(79)^2-2(27)(79)\cos (142^\circ)[/tex]
[tex]z^2=729+6241-4266(-0.788)[/tex]
[tex]z^2=6970+3361.608[/tex]
[tex]z^2=10331.608[/tex]
Taking square root on both sides.
[tex]z=\pm \sqrt{10331.608}[/tex]
[tex]z=\pm 101.6445178[/tex]
Approx the above value to the nearest number and side length cannot be negative. So,
[tex]z\approx \pm 102\text{ cm}[/tex]
Therefore, the length of z is about 102 cm.

Answer:
Step-by-step explanation:
We need to isolate "x" on one side of the inequality symbol, then we divide both sides by "-3", recalling that dividing by a negative number changes the direction of the inequality:
- 3 x < - 15
x > (-15) / (-3)
x > 5
Which can be represented on the number line as shown in the attached image.
Which is equivalent to (2x^2y)(8x^3y^3)?
Answer: A
Step-by-step explanation: In order to answer this you need to understand the rules of exponents. Whenever you multiply two terms with the same base or variable you add the powers together. For example, 4x*2x = 8x^2 or x^4*x^2 = x^6. Any term with a negative exponent is equivalent to its reciprocal. For example x^-2 = 1/x^2.
Knowing this we expand this equation by multiplying. (2x^-2y) * (8x^-3y^-3) = 16x^-5y^-2. We now move the variables with negative exponents to the bottom. Giving us 16/(x^5y^2).

[tex] \sqrt[3]{49} = 3.65930571002 \approx3.66 \\ \\ so \: \sqrt[3]{49} should \: lie \: at \: 3.6 \: which \: \\ fall \: between \: 3 \: and \: 4.[/tex]
Actually Lin did a mistake, she obtained square root and not cube root.
Answer with Explanation:
[tex]3\sqrt{49}[/tex] should be placed in-between 3 and 4 on the number line (a little bit approaching number 4). The cube root of 49 is 6.66. Therefore, it shouldn't be placed on number 7.Lin thought that she was asked to get the square root of 49, which looks like this: [tex]\sqrt{49}[/tex]. Probably, she missed the number 3. It was actually asking for the cube root of 49. This is also the reason why she placed the dot on the number 7 because the square root of 49 is 7.

Solving systems of equations by graphingStep-by-step explanation:
The solution set of the systems of equations would be where the 2 lines intersect. If the 2 lines do not intersect (i.e they are parallel lines), then they will have no solution. If the 2 lines look exactly the same, then they will have infinitely many solutions.
From the graph, we see that the lines intersect once. Therefore, the systems has 1 solution.

Y=5xー2
equals what ? HELPP!!
Answer:
X=-0.4
Y= - 2
Step-by-step explanation:
First we slove for x intetcept so we put 0 for y.
Y=5X-2
0=5X-2 Now move the variables to
the left side.
5x=-2 Divide both sides by 5
because the coefficient
of your variable is 5.
X=-0.4
Now let's solve for Y intetcept.
Y=5X-2
Y=5(0)-2
Y=-2

Jen says that the solutions of the inequality -2(3 – x) > 2x – 6 are all real numbers. Do you agree with your friend? Explain. What if the inequality symbol were ≥?
Answer:
I disagree
'No it won;t
Step-by-step explanation:
Given the inequality functions;
-2(3 – x) > 2x – 6
Open the parenthesis
-2(3) -2(-x) > 2x - 6
-6 + 2x > 2x - 6
Collect like terms
2x-2x > -6 + 6
0x > 0
x > 0/0
The value of x does not exist on any real number. I disagree with my friend since the value of x is an indeterminate function. If the inequality were ≥, it won't change anything as the value of x won't still exist on any real number
