Which lines are perpendicular to the line y - 1= 1(x+2)? Check all that apply
y2= -36% -4)
y-5=9(x - 11)
• y=-3x-2/
y = 1x-2
3x + y=7
) Intro
Done
Step-by-step explanation:
Given the line y-1 = 1(x+2), in order to know the line that is perpendicular to the given line, we will first find the slope of the known line.
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the intercept
Rewrite the equation given
y-1 = 1(x+2)
y-1 = x+2
y = x+2+1
y = x+3
Comparing to the standard form, the slope m = 1.
For two lines to be perpendicular, the product of their slope must be -1 i.e mM = -1
Substitute
1(M) = -1
M = -1
For us to know the line that is perpendicular to the given line, its slope must be -1.
Since none of the equation has a slope of -1, hence none of the lines are perpendicular to the line y - 1= 1(x+2).

What is inequality?
A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.
Now the given inequality is,
a(x + 3) < 5x + 15 - x
or, a(x + 3) < 4x + 15
Now let us solve for x first,
⇒ ax + 3a < 4x + 15
Subtract 3a from both sides we get,
ax < 4x + 15 - 3a
Subtract 4x from both sides we get,
ax - 4x < 15 - 3a
or, (a - 4)x < 15 - 3a
Dividing both the side by (a - 4) we get,
x < (15 - 3a) / (a - 4)
Now for solutions to be real numbers,
a - 4 > 0
subtracting 4 both the side we get,
⇒ a > 4
this is the required value of a for which the solution of the inequality is all real numbers
Thus, the required value of a for which the solution of the inequality is all real numbers is a > 4.

If f(x) = 5x - 3, fill out the following table of values:
-2,-1,0,1,2,3
What type of function is this?
Answer:
Step-by-step explanation:
Given function is,
f(x) = 5x - 3
Where f(x) represents the output values and 'x' is the variable representing the input values.
For x = -2,
f(-2) = 5(-2) - 3
= -13
For x = -1,
f(-1) = 5(-1) - 3
= -8
For x = 0,
f(0) = 5(0) - 3
= -3
For x = 1,
f(1) = 5(1) - 3
= 2
For x = 2,
f(2) = 5(2) - 3
= 7
For x = 3,
f(3) = 5(3) - 3
= 12
Table for the input-output values will be,
x -2 -1 0 1 2 3
f(x) -13 -8 -3 2 7 12
Since the values of f(x) has a common difference of [-13 - (-8) = -5] negative five, given function will be a linear function.

What is the slope-intercept form of a line?The slope-intercept form of a line is represented by y=mx+c where m=slope and c is the y-intercept of the line
Given here: The graph of a line that passes through the point (0,-1)
We know the slope intercept form of a line is given by
y=mx+c
Thus if the line passes through this point then
-1=m×0+c
c=-1
Again we can clearly observe that one of the points that lie on the line is (-1,3)
3=-m-1
m=4
∴ The required equation is y=4x-1

On a graph.
Answer:
The answer will be listed below!
Step-by-step explanation:
To graph the equation y=3/2x+2, you must know what 3/2x is and what 2 is. 2 would be your y-intercept as the 3/2x would be your slope. As you can see, look for 2 on the y axis and place a dot there. Now, take your slope and use rise/run which means up three and to the right 2. After you finish, draw a line through it and you have graphed it!

Step-by-step explanation:
Kiran sells f full boxes and h half-boxes of fruit to raise money for a band trip. He earns $5 for each full box and $2 for each half-box of fruit he sells and earns a total of $100 toward the cost of his band trip. The equation 5f+2h=100 describes this relationship. Solve the equation for f.
Answer:
f = (100 - 2h) / 5
Step-by-step explanation:
Given:
5f + 2h = 100
Solve the equation for f.
5f + 2h = 100
Subtract 2h from both sides
5f + 2h - 2h = 100 - 2h
5f = 100 - 2h
Divide both sides by 5
5f / 5 = (100 - 2h) / 5
f = (100 - 2h) / 5
If f = 1 full box
h = 1/2 box
h = 1/2 of f
h = 1/2f
Substitute h = 1/2f into
f = (100 - 2h) / 5
f = {100 - 2(1/2f)} / 5
f = (100 - 2/2f) / 5
5f = 100 - f
5f + f = 100
6f = 100
f = 100 / 6
= 16.67
f = 16.67
The required value of f is 16.67.
Given that ;
Kiran sells full box of fruit cost for each box = f = $5
And Kiran sells half box of fruit cost for each = h = $2
According to the question ;
For full box cost + for half box cost = Total cost of his band trip
5f + 2h = 100
Solve the equation following equation for f .
5f + 2h = 100
Subtract 2h from both sides
5f + 2h - 2h = 100 - 2h
5f = 100 - 2h
Divide both sides by 5
[tex]\frac{5f}{5} = \frac{100}{5} - \frac{2h}{5}[/tex]
f = 20-2h
For full box f = 1 full box
For half box h = 1 half box
It means h = [tex]\frac{1}{2}[/tex] of f
h = [tex]\frac{1}{2}f[/tex]
Substitute the value of h
[tex]f = \frac{(100-2h)}{5} \\f = \frac{100-2(\frac{1}{2f} )}{5}[/tex]
[tex]f = \frac{100-f}{5}[/tex]
5f = 100 - f
5f + f = 100
6f = 100
[tex]f = \frac{100}{6}[/tex]
f = 16.67
The required value of f is 16.67.
