y=2/3x hope this helps!
The equation of a line from the given graph is y=2/3 x. Therefore, option A is the correct answer.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
From the given table, the coordinate points are (0, 0) and (6, 4)
Here, slope m=(4-0)/(6-0)
= 2/3
Substitute, m=2/3 and (x, y)=(0, 0) in y=mx+c, we get
0=2/3(0)+c
c=0
Substitute, m=2/3 and c=0 in y=mx+c, we get
y=2/3 x
Therefore, option A is the correct answer.

The given equation has one solution which is the variable x = -27.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.
The equation is given in the question,
0.4(5x – 15) = 2.5(x+3)
Multiply both sides by 10
0.4(5x – 15) × 10=25(x+3) × 10
Refine
4(5x–15) =2.5(x+3)
Expand 4(5x-15): 20x-60
Expand 25(x+3): 25x+75
20x-60 = 25x+75
Add 60 to both sides
20x-60+60 = 25x+75 +60
Simplify the above equation,
20x=25x+135
Subtract 25x from both sides
20x-25x = 25x+135-25x
-5x = -135
Divide both sides by -5
-5x / -5 = -135/5
x = -27
Therefore, the given equation has one solution which is the variable x = -27.

Which ordered pair is a solution of the equation?
Answers
Answer:
D, neither
Step-by-step explanation:
If you want to solve this through elimination, just substitute the given points in each choice. (a,b) → (x,y)
In a coordinate the first number is the x value, and the second is the y.
All you have to do is substitute the indicated values given in the coordinate into the point slope equation, and determine whether or not the equation is true. If the equation is true (for example 1 = 1) the order pair IS a solution. If the equation is false (for example 1 = 2), than the ordered pair IS NOT a solution.
If you want to look at this linear equation solving for the quantity y, then use slope intercept.
Choice 1 is incorrect because (5,4) →
y - 4 = 7(x - 6) → (4) - 4 = 7((5) - 6) →
0 = 7(-1) → 0 = -7 (0 is never equal to -7) ; contradictory
Choice 2 is incorrect because (6,5) →
y - 4 = 7(x - 6) → (5) - 4 = 7((6) - 6) →
1 = 7(0) → 1 = 0 (1 is never equal to 0) ; contradictory
Therefore Choice 3 must be incorrect as well because neither of these two pairs are solutions, so combining two pairs that do not satisfy the equation does not make it any more true.
Since Choice 4 is the remaining choice, it must be the correct answer.
The points that fit on this line are given by the slope intercept equation: y = 7x - 3.
To convert point slope form to slope intercept form, first distribute everything in the parenthesis. Then remove all the terms besides y from the left side of the equation to the right:
y - 4 = 7(x - 6) → y - 4 = 7(x) + 7(-6) →
y - 4 = 7x - 42 → y - 4 + 4 = 7x - 42 + 4 →
y = 7x - 38.
Just substitute the x or y value into the equation, and find the corresponding y or x variable that fits the line.

The monthly cost of a short term disability insurance policy varies directly as the salary of the employee. Wanda has an annual salary of $38,500, and the monthly cost for her policy is $11.55. Randy has an annual salary of $49,500. What should Randy expect to pay for his policy?
Answers
Answer: $14.85
Step-by-step explanation:
Ww can solve the question using direct proportion with the formula y = kx
where y = annual salary
x = monthly policy cost.
k = constant of proportionality
Since y = kx
38500 = 11.55k
k = 38500 / 11.55
k = $3333.33
When Randy has an annual salary of $49,500, the amount Randy expect to pay for his policy will be:
y = kx
49500 = 3333.33x
x = 49500 / 3333.33
x = 14.85
The amount that Randy expect to pay for his policy will be $14.85
Write a linear function f with f(2)=−2 and f(1)=1.
Answers
Answer - the answer should be: -3x+4
down below is how i did it,
Step-by-step explanation:
use the formula mx+b=y
y is f(x)
m = -3
x = x
b = 4
so,
mx+b is -3x+4
A linear function is the function of a straight line.
The linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]
The given parameters are:
[tex]\mathbf{f(2) =-2}[/tex]
[tex]\mathbf{f(1) =1}[/tex]
Calculate the slope (m)
[tex]\mathbf{m = \frac{f(b) - f(a)}{b -a}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{-2-1}{2 -1}}[/tex]
[tex]\mathbf{m = \frac{-3}{1}}[/tex]
[tex]\mathbf{m = -3}[/tex]
The linear function is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
This gives
[tex]\mathbf{y = -3(x - 1) + 1}[/tex]
[tex]\mathbf{y = -3x + 3 + 1}[/tex]
[tex]\mathbf{y = -3x + 4}[/tex]
Rewrite as:
[tex]\mathbf{f(x) = -3x + 4}[/tex]
Hence, the linear function is: [tex]\mathbf{f(x) = -3x + 4}[/tex]

c is the answer
Step-by-step explanation:
5x+7 ≤ -3

Answer:
C
Step-by-step explanation:
We have the compound inequality:
[tex]5x+7\leq-3\text{ or } 3x-4\geq11[/tex]
We will solve each inequality individually and then combine them at the end.
For the first inequality, we have:
[tex]5x+7\leq-3[/tex]
Subtract 7 from both sides:
[tex]5x\leq-10[/tex]
Divide both sides by 5:
[tex]x\leq-2[/tex]
For the second inequality, we have:
[tex]3x-4\geq11[/tex]
Add 4 to both sides:
[tex]3x\geq15[/tex]
Divide both sides by 3:
[tex]x\geq5[/tex]
Since our original inequality was an “OR,” our solution set is also an “OR.”
Hence, our solution is:
[tex]x\leq-2\text{ or } x\geq5[/tex]
Thus, our answer is C.

Step-by-step explanation:
4x-58=74

4x=132
4x/4=132/4
x=33
If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
It is known that the If two parallel lines intersect another two parallel lines then all corresponding angles will be the same.
Therefore, 74 = 4x - 58
4x = 132
x = 33.
Since 74° and the adjacent angle of y° are made by two parallel lines on the same line thus both will also same.
The adjacent angle of y = 74°
Since, adjacent angle + y = 180°
y = 180 - 74 = 106°.
Hence "If two parallel lines intersect another two parallel lines then all corresponding angles will be the same thus the value of y is 106° and x is 33°".

Answer:
No
Step-by-step explanation:
[tex]\frac{2}{3} \frac{5}{6}[/tex]
2 goes into 6 3 times so it would be the same as 1 going into 3 3 times.
[tex]\frac{1}{3} \frac{5}{3}[/tex]
Since 3 doesn't go into 5 at all (and by that I mean a whole number) you don't change it.
Multiplying 1/3 and 5/3, you would get 5/9.
Multiplying 2/3 and 5/6, you would get 10/18, which simplifies to 5/9.
That is kind of how cross multiplying works.
