Answer:
y=-7
Step-by-step explanation:
Simple enough. Slope of zero means that x does not have to be determined. So if you just put the y coordinate in a slope of zero, you should get your answer.
The equation of line is y = -7.
Equation of line is,
[tex]y=mx+c[/tex]
Where m is slope.
Given that, slope is 0.
Equation of line become, [tex]y=0*x+c=c[/tex]
And Line passes through the point (5, -7)
Substitute these point,
[tex]c=-7[/tex]
Hence, equation of line is, [tex]y=-7[/tex]

Karla buys t-shirts to promote her local business. She develops the inequality t > 100 for the number of t-shirts she needs to sell in order to make a profit. Answer the following questions. If she is selling each shirt for $15 dollars, how much money did Karla spend to make the t-shirts? How do you know?How much money would Karla have lost if she sells only 90 t-shirts?
Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.
What is an inequality?An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let t represent the number of t-shirts she needs to sell in order to make a profit. Since:
t > 100 and the price is $15 per shirt, hence:
Money spent = $15 * 100 = $1500
Money lost in sell 90 shirts = (100 - 90) * 15 = $150
Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.

the length of a rectangle is 1 more than 3 times the width. if the perimeter is 98. what is the length ?
Answer:
length = 37
Step-by-step explanation:
w= x
l= 3x + 1
to get the perimeter you need to add all sides.
x + x + 3x + 3x + 1 + 1 = 98
8x + 2 = 98
8x = 96
x = 12
To get the length plug in the value of the x to 3x + 1.
length = 3(12) +1
length = 37

f(x)=x2+9f x = x 2 + 9
f(x)=x2−6x+9f ( x ) = x 2 − 6 x + 9
f(x)=x2+6x+9f ( x ) = x 2 + 6 x + 9
Answer:
[tex]\large\boxed{\sf f(x) = x^2-6x+9}[/tex]
Step-by-step explanation:
We are here given a graph of a equation and we are interested in finding the equation .
From the given graph we can see that it cuts the x axis at point (3,0) . This graph represents a quadratic function and its two zeroes are 3,3 . We can write the equation using the two zeroes .
Say if the zeroes of the quadratic equation are p and q , then the quadratic equation can be written as ,
[tex]\longrightarrow (x-p)(x-q)=0 [/tex]
And the quadratic function can be written as ,
[tex]\longrightarrow f(x)= k[ (x-p)(x-q)][/tex]
where k is a constant .In this case k = 1 . So we can write the function as ,
[tex]\longrightarrow f(x) = (x-3)(x-3)[/tex]
Distribute ,
[tex]\longrightarrow f(x)= x (x-3)-3(x-3)[/tex]
Simplify by opening the brackets,
[tex]\longrightarrow f(x) = x^2-3x -3x +9 [/tex]
Add like terms,
[tex]\longrightarrow \underline{\underline{f(x) = x^2-6x+9}}[/tex]

What is the perimeter of the rectangle?Let W be the rectangle's width and L its length. The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
The width of a rectangular flower shop is 20 feet less than twice the length.
W = 2L - 20
The perimeter is more than 70 feet. Then the inequality is given as,
P < 2(L + W)
70 < 2(L + 2L - 20)
70 < 2L + 2(2L - 20)
Replace L with x, then we have
2x + 2(2x - 20) > 70
The perimeter is represented by the inequality 2x + 2(2x - 20) > 70. Then the correct option is B.

Work out 4/5 - 3/20 - 2/10
Answer:
9/20
Step-by-step explanation:
LCM of 5, 20, and 10 = 20
4/5
= 4/5 x 4/4
= ( 4 x 4 )/( 5 x 4 )
= 16/20
2/10
= ( 2/10 ) x ( 2/2 )
= ( 2 x 2 )/( 10 x 2 )
= 4/20
4/5 - 3/20 - 2/10
= 16/20 - 3/20 - 4/20
= ( 16 - 3 - 4 )/20
= ( 16 - 7 )/20
= 9/20
Answer:
9/20
Step-by-step explanation:
First, you need to find common denominators between all of the fractions.
All of these denominators can be multiplied by a whole number to equal 20.
For 4/5, multiply both the numerator and the denominator by 4 to get 16/20
Leave 3/20 alone
For 2/10, multiply both the numerator and the denominator by 2 to get 4/20
Now you have 16/20 - 3/20 - 4/20
= 9/20

Quadrilateral DEFG has coordinates D (2, 1), E (2, 6), F (5, 6), and G (5, 1). How can quadrilateral DEFG be classified?
Group of answer choices
rhombus but not a square
parallelogram but neither a rhombus nor a rectangle
rectangle but not a square
square
Answer:
Rectangle but not a square
Step-by-step explanation:
Let's start by determining if it's a parallelogram.
The slope of side DE is undefined.
The slope of side EF is 0.
The slope of side FG is undefined.
The slope of side DG is 0.
Thia means we have 2 pairs of opposite parallel sides, meaning DEFG is a rhombus.
Now, let's determine if it's a rectangle. Since the slope of
side DE is undefined and the slope of side EF is 0, sides DE and EF are perpendicular. This means that angle DEF is a right angle, and thus DEFG is a rectangle.
To determine if DEFG is a rhombus, we can find the lengths of adjacent sides DE and EF.
The length of DE is 5.
The length of EF is 3.
Since the pair of consecutive sides (sides DE and EF) aren't congruent, DEFG is not a rhombus.
Since DEFG is not a rhombus, it also cannot be a square.
This means DEFG is a rectangle, but not a square.
Arianna and Blair are working on a problem together: Solve x/3 + 8 = -2. Blair thinks the first step is to multiply by 3. Arianna explains that this, not the most efficient way to solve. Explain who is correct and justify your reasoning.
x/3 + 8 = -2
Because x is in a fraction, the most efficient way to solve is to remove the 8 first.
The first step should be to subtract 8 from both sides:
x/3 = -10
Then you would multiply both sides by 3:
x = -30
Blair was correct but Arianna is correct too.
Let's see why :
_________________________________ We're gonna solve it from Blair's method .
[tex] \frac{x}{3} + 8 = - 2 \\ [/tex]
Multiply sides by 3
[tex]x + 24 = - 6[/tex]
Subtract sides minus 24
[tex]x = - 6 - 24[/tex]
[tex]x = - 30[/tex]
_________________________________
The faster way is :
[tex] \frac{x}{3} + 8 = - 2 \\ [/tex]
Subtract sides minus 8
[tex] \frac{x}{3} = - 2 - 8 \\ [/tex]
[tex] \frac{x}{3} = - 10 \\ [/tex]
Multiply sides by 3
[tex]x = - 30[/tex]
It is very easier to calculate -2-8 than -24-6 and also it is very easier to multiply -10 by 3 than multiply 8 by 3 and multiply -2 by 3 and then calculate.
So Arianna is correct.
I think this is the correct answer.
Thanks for watching buddy good luck.

Write an equation of the perpendicular bisector of the segment with endpoints G(5,-8) and H(7,4) Your answer should be in slope-intercept form. Please type your equation with NO SPACES and if the slope is not a whole number, please make sure it is written as a faction.
Answer:
[tex]y=-\frac{1}{6}x-1[/tex]
Step-by-step explanation:
In order to solve this problem we can start by finding the slope of the perpendicular equation. We can do this by finding the slope of the equation that passes through the two points provided by the problem.
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
so we input the two points (5,-8) and (7,4) to get:
[tex]m=\frac{4-(-8)}{7-5}[/tex]
so
m=6
next, we find the negative reciprocal to get the slope of the perpendicular line, so we get:
[tex]m=-\frac{1}{6}[/tex]
Now we need to find one point that the line passes through.
we can find that point by using the midpoint formula:
[tex]x=\frac{x_{2}+x_{1}}{2}[/tex]
[tex]y=\frac{y_{2}+y_{1}}{2}[/tex]
so we get:
[tex]x=\frac{7+5}{2}=6[/tex]
[tex]y=\frac{4-8}{2}=-2[/tex]
So the point is (6,-2)
So now we can find the equation of the line by using the point-slope form of the linear equation:
[tex]y-y_{1}=m(x-x_{1})[/tex]
and substitute the point and the slope into the equation:
[tex]y-(-2)=-\frac{1}{6}(x-6)[/tex]
and solve for y:
[tex]y=-\frac{1}{6}x+1-2[/tex]
[tex]y=-\frac{1}{6}x-1[/tex]
which will be our answer.
