Answer:
y=1/2x-5
Step-by-step explanation:
We have slope so we just need to find the y intercept.
slope intercept formula is
y=mx+b
(m) is slope
(b) is y int
y=1/2x+b
now apply our given x and y values (4 & -3)
-3=1/2(4)+b
simplify
-3=2+b
subtract 2 from each side
-5=b
put that into our equation
y=1/2x-5

Answer:
40
Step-by-step explanation:
It's basically reverse-simplifying. You can cross multiply, but for me, the easiest thing is to look and see how 3 turned in to 12. To get 12 from 3, you multiply by 4. So then multiply 10 by 4 and you get 40. Hope this helps!! :)

In graph, the area below f(x) is shaded and labeled A, the area below g(x) is shaded ad labeled B, and the area where f(x) and g(x) have shading in common is labeled AB
the graph represents which system of inequalities?
y≤-2x+3
y≤x+3
y≥-2x+3
y≥x+3
y≤-3x+2
y≤-x+2
y>-2x+3
y>x+3
Answer:
The graph represents the system of inequalities y ≤ -3x + 2 and y ≤ -x + 2 ⇒ C
Step-by-step explanation:
From the given figure
∵ The direction of each line is to left
∴ The slopes of the lines are negative
∵ The slope of the line is the coefficient of x
∴ The coefficient of x in each inequality is negative ⇒ (1)
∵ The two lines intersect the y-axis at the point (0, 2)
∴ The y-intercept of the two lines is (0, 2)
∵ The y-intercept is the numerical term in the equation
∴ The numerical term in each inequality is 2 ⇒ (2)
∵ The two lines are solids
∵ The shaded area of each one is under the line
∴ The sign of inequality in both equations is ≤ ⇒ (3)
→ Look at the answer and find which one has the 3 conditions above
∵ y ≤ -3x + 2 and y ≤ -x + 2
∴ m = -3 and m = -1 ⇒ negative coefficients of x
∴ b = 2 ⇒ numerical term
∵ The sign of inequality is ≤
∴ The graph represents the system of inequalities y ≤ -3x + 2 and y ≤ -x + 2
Find the measure of the missing angle.
32 a
Answer:
Soln,
32°+a=90°[right angled triangle]
or,a=90°-32°
or,a=58°
•°•a=58°
The measure of the missing angle is, a = 58 degree
Used the concept of complementary angle that states,
The sum of complementary angles is always equal to 90 degrees.
Given that,
There are two angles shown in the image.
From the given image,
Angle a and 32 are complementary angles.
Hence,
a + 32° = 90°
a = 90° -32°
Therefore, the missing angle is,
a = 58 degree

The work in an office takes 150 hours to complete every week.
Each person in the office works for 32 hours a week.
What is the smallest number of people needed to complete the work?
Answer: A minimum of 5 people will be needed.
Step-by-step explanation:
150/32 = 4.6875
You can't have a partial person, so round up to 5.
It may be possible to have 4 employees working 32 hours and another working 22 hours, but that is not what the question asks exactly. That is still 5 people.

Ada Lovelace had 210 minutes to read, play soccer, and code her computer.
She spent t minutes reading
She spent 2(t +18) minutes playing soccer
She spent 30 minutes coding.
How many minutes did Ada spend reading
Answer:
She spent 48 minutes reading
Step-by-step explanation:
Here, we want to calculate the number of minutes spent reading
By adding all the breakdown of individual tasks, we get the total
Thus, mathematically;
30 + 2(t + 18) + t = 210
30 + 2t + 36 + t = 210
3t = 210-30-36
3t = 144
t = 144/3
t = 48
From the question, she spent t minutes reading which means she spent 48 minutes reading

Parallelogram RSTU is constructed with line AB drawn through its center. If the parallelogram is
dilated using a scale factor of 4 and a line is drawn through the center of the new dilated figure,
what relationship will the new line have with line AB? Explain your reasoning using complete
sentences. (10 points)
Answer: New line = 4AB
Step-by-step explanation:
If a figure is dilated with a scale factor of k , then the measure of new side length = k x (Original side)if AB a line through center of parallelogram RSTU is drawn , then, after dealation with scale factor k= 4 , the length of new line through center = 4 x AB or 4AB.
The relationship will the new line have with line AB :
New line = 4AB

What number is the first multiple of 5 that is greater than 17
Answer:
20
Step-by-step explanation:
Multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, etc. Each multiple is created by multiply 5 times some other number.
The first multiple of 5 that is greater than 17 is 20.
What are multiples of a number?Multiples of a number is simply it's table.
We know 5 has a multiple of 20 which is 5 times 4 and we also know that
20 > 17.
Now the previous multiple of 5 before 20 is 15 which is not greater than 17 and 25 is also a multiple of 5 but 20 comes before 25.
So, the most appropriate multiple of 5 that is greater than 17 that is greater than 17 is 20.
