Answer:
-4/3
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
-3-5/8-2
-8/6
-4/3
Best of Luck!
Answer:
-4/3
Step-by-step explanation:
You can use rise/run. The rise (y values) goes from 5 to -3. You subtract 8 for this. The run (x values) goes from 2 to 8. You add 6 for this. the proportion is -8/6, which can be simplified to -4/3.
Therefore, the slope is -4/3!

1)A triangle has sides that measure 3 cm, 8 cm, and 4 cm. Do these measurements form a right
triangle?
A. Yes
B. No
Answer:
A. Yes
Step-by-step explanation:
the 8cm will be the hypotenuse and the 4cm and 3cm will join to create a right triangle.
Answer:
by using Pythagoras theorem,
a^2 + b^2 = c^2
LHS
3^2 +4^2
9 + 16 = 25

Can someone help
Answer:
Hope this helps have a good day! :)
Step-by-step explanation:
Exact form = 10/3
Decimal form = 3.3
Mixed number form = 3 1/3
the solution for x is x = 10/3 or approximately x = 3.33.
To solve for x in the equation 8x - 2 - 5x = 8, we need to simplify and combine like terms, then isolate x on one side of the equation.
Let's start by combining the x terms on the left side:
(8x - 5x) - 2 = 8
Simplifying further:
3x - 2 = 8
Next, we want to isolate the x term. We can do this by adding 2 to both sides of the equation:
3x - 2 + 2 = 8 + 2
Simplifying the equation:
3x = 10
Finally, to solve for x, we divide both sides of the equation by 3:
(3x) / 3 = 10 / 3
The division yields:
x = 10/3
Therefore, the solution for x is x = 10/3 or approximately x = 3.33.

The amount of fertilizer needed for a lawn varies directly with the area of the lawn Mr. Dundee lawn is a rectangular shape and measures 78' x 93' 4 pounds of fertilizer are needed for 750 ft.² of lawn how much is needed for Mr. Dundees lawn to the nearest whole pound
Answer:
39 pounds is needed
Step-by-step explanation:
Given
Lawn Dimension: 78' by 93'
4 pounds fertilizer for 750ft² area
Required
Determine the amount needed for the given dimension
First, we need to calculate the area of the lawn
[tex]Area = 78' * 93'[/tex]
' means feet
So:
[tex]Area = 78ft * 93ft[/tex]
[tex]Area = 7254 ft^2[/tex]
Let the amount of fertilizer need be x
So, we have:
4 pounds = 750ft²
and
x = 7254ft²
Cross Multiply:
[tex]x * 750 = 4 * 7254[/tex]
[tex]x * 750 = 29016[/tex]
Solve for x

Pedro is a salesman for a department store. He earns a commission of 8.5% on his sales. If he sold $1,200 in merchandise, what would his total commission be?
Answer: $102
Step-by-step explanation:
From the question, we are informed that Pedro earns a commission of 8.5% on his sales and that he sold $1,200 in merchandise.
Therefore, his total commission will be:
= 8.5% × $1200
= 8.5/100 × $1200
= 0.085 × $1200
= $102

What is a sphere?It is a three-dimensional figure where the volume is given as
= 4/3 x πr³
We have,
Current gumball machine.
Diameter = 22 inches
Radius = 22/2 = 11 inches
Volume = 5,575 cubic inches
The volume can be written as,
4/3 x πr³ = 5575
4/3 x 22/7 x r³ = 5575

Write the equation of the line in slope-intercept form that has: slope: -1 point: (2, -3) *
Answer:
y = -1x - 3
Step-by-step explanation:
y = mx + b
m = slope = -1
b = y-intercept = -3
Plug in
y = -1x - 3
Answer:
y = -x - 1
Step-by-step explanation:
Slope - Intercept form is y = mx + b
m = slope
b = y-intercept
We already have the slope of -1. Substitute it into the equation.
y = -x + b
To find b, substitute the given point (2, -3) into the equation.
-3 = -2 + b
b = -1
Substitute the value of b into the equation and you are left with:
y = -x - 1
AXYZ is in Quadrant 1. It is rotated 90° counterclockwise around the origin.
Then AX'Y'Z' is reflected across the y-axis. Then AX"Y"Z" is translated 5 units to
the right. In which Quadrant is AX"Y"" Z"'? How do you know?
Answer:
Quad 1
Step-by-step explanation:
AXYZ is in the 2nd quad bc of the rotation, then goes back to 1st quad bc of reflection (y axis). After this, the translation doesn't affect the movement of quadrants. A""X""Y""Z"' lands in quadrant 1.
Answer:
1st quadrant
Step-by-step explanation:
1. Rotated 90° counterclockwise from the 1st quadrant, moves object to the second quadrant.
2. Reflection across y-axis, moves object back to the 1st quadrant.
3. Translation to the right is moving to the right inside the 1st quadrant.

In the arithmetic sequence 5,2,-1,-4 what term is -25?
Answer:
Thus, the eleventh term is -25.
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the sequence:
5,2,-1,-4,...
We can directly find the common difference by subtracting two successive terms:
r = 2 - 5 = -3
The same result is obtained by subtracting any pair of successive terms.
The first term is a1 = 5. The general equation is:
[tex]a_n=5-3(n-1)[/tex]
[tex]a_n=5-3n+3[/tex]
[tex]a_n=-3n+8[/tex]
We need to find which term is -25, thus:
-3n + 8 = -25
Subtracting 8:
-3n = -25 - 8 = -33
Dividing by -3:
n = -33 / (-3)
n = 11
Thus, the eleventh term is -25.

The student council receives 35% of the sales from the tickets to a school dance. If they received $196.00, what was the total of the ticket sales? i need help!
Answer:
$560
Step-by-step explanation:
The student council receives 35% of the sales from the tickets to a school dance.
Let us represent the total of the ticket sales as x
35% of x = $196.00
35/100 × x = $196
35x/100 = $196
Cross Multiply
35x = $196 × 100
x = 196 × 100/35
x = $560
The total of the ticket sales is 560
