d. -3
Answers
Answer:
Step-by-step explanation:
1. Slope = (y2-y1) / (x2-x1) = -3-0/ -1-4= -3/-5= 3/5 (d)
2.
Compare to the equation y= mx+b, where m is the slope
3y = 15x+9 divide by 3 each term
y = 15x/3 +9/3
y= 5x + 3 so slope is 5 ( a)
3.
use first the equation point- slope y-y1 =m (x-x1) and rearange it to be in slope-intercept form y=mx +b
y-y1 =m (x-x1)
y-2 = -3( x-1)
y = 2-3x+3
y= -3x +5 ( c)
4.
if the point y- intercept is at (0, 3) then the y-intercept is b=3
y= mx+b
y = 2x +3 (a)
5.
the equation point- slope y-y1 =m (x-x1), find the slope m= (y2-y1) / (x2-x1)
m= 3-12/ 1+2 = -9/3 = -3
y-1 = -3(x-3) is (a)
6.
y-intercept is at -4 ( yet the graph is off a bit -tell your teacher)
slope m = 1
so the equation is y=mx+b and here is y=x -4 (c)
7.
the slope is m= (y2-y1) / (x2-x1) si pich any two points from the table and calculate the slope
for example (0, 3) and (1, 0)
m = (3-0)/ (0-1) = 3/-1 = -3 (d)
1. Slope = (y2-y1) / (x2-x1) = -3-0/ -1-4= -3/-5= 3/5 (d)
2.
Compare to the equation y= mx+b, where m is the slope
3y = 15x+9 divide by 3 each term
y = 15x/3 +9/3
y= 5x + 3 so slope is 5 ( a)
3.
use first the equation point- slope y-y1 =m (x-x1) and rearange it to be in slope-intercept form y=mx +b
y-y1 =m (x-x1)
y-2 = -3( x-1)
y = 2-3x+3
y= -3x +5 ( c)
4.
if the point y- intercept is at (0, 3) then the y-intercept is b=3
y= mx+b
y = 2x +3 (a)
5.
the equation point- slope y-y1 =m (x-x1), find the slope m= (y2-y1) / (x2-x1)
m= 3-12/ 1+2 = -9/3 = -3
y-1 = -3(x-3) is (a)
6.
y-intercept is at -4 ( yet the graph is off a bit -tell your teacher)
slope m = 1
so the equation is y=mx+b and here is y=x -4 (c)
7.
the slope is m= (y2-y1) / (x2-x1) si pich any two points from the table and calculate the slope
for example (0, 3) and (1, 0)
m = (3-0)/ (0-1) = 3/-1 = -3 (d)

Plainfield Community Center is buying new seating for their building. They want to purchase a combination of stools and chairs. Stools cost $50 and chairs cost $65. The center cannot spend more than $3000.
Which inequality represents all possible combinations of s stools and c chairs?
a) 50s + 65c ≤ 3000
b)50c + 65s ≤ 3000
c) 50c + 65s ≥ 3000
d) 50s + 65c < 3000
Answers
Answer:
A
Step-by-step explanation:
If you have s number of stools and c number of chairs, the price can be expressed as 50s + 65c. Since the question says you cannot spend more than 3000, you could spend less than or equal to 3000. So the inequality is 50s + 65c ≤ 3000.

HELPPPPPP SOLVE FOR X
Answers
Answer:
x = 6
Step-by-step explanation:
These are supplementary angles.
This means that the angles add up to 180 degrees.
The first thing we can do is set 6y equal to 90, because the little red box means that is 90 degrees.
6y = 90
y = 15
Now that we have found y we can solve for x.
Plug in the y to the 5x + 4y
5x + 4(15)
5x + 60
We can set this equal to 90 again
5x + 60 = 90
5x = 30
x = 6
Therefore x is equal to 6.
I hope this helps!!
- Kay :)
Answer:
x= 6
Step-by-step explanation:
Straight line: is equaled to 180 degrees.
6y= 90 (90 divided by 6= 15), so y= 15
5x + 4y= 90 --> 5x + 4(15)= 90 --> 5x + 60= 90 --> 90 - 60= 30 --> 5x= 30 (30 divided by 5= 6), so x= 6

The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).

The required value of f(-2.2) is 1 for the given function f(x)=x+3. The correct answer is an option (C).
The given function is f(x)=x+3.
To find f(-2.2) on the given graph of f(x) = x + 3, we need to locate the corresponding point on the step graph.
From the information provided, we know that the left-most segment starts at (-5, -1) and ends at (-4, -1), and each segment is 1 unit higher and 1 unit farther to the right than the previous segment.
To determine the value of f (-2.2), we need to find the segment that includes the x-coordinate of -2.2.
Since the x-coordinate -2.2 falls between -4 and -3 (1 unit to the right of the left-most segment), the corresponding y-coordinate is 2 units higher than the starting y-coordinate of -1.
So, f(-2.2) = −1 + 2
f(-2.2) = 1.
Thus, the required value of f(-2.2) is 1.

Answers
Answer:

Step-by-step explanation:
Let's solve your equation step-by-step.
180=x+3x−8
Step 1: Simplify both sides of the equation.
180=x+3x−8
180=x+3x+−8
180=(x+3x)+(−8)(Combine Like Terms)
180=4x+−8
180=4x−8
Step 2: Flip the equation.
4x−8=180
Step 3: Add 8 to both sides.
4x−8+8=180+8
4x=188
Step 4: Divide both sides by 4.
4x4=1884
