The graph shown below represents a ladder leaning against wall the bottom of the latter is 4 feet from the wall in the top of the ladder reach is 20 feet above the ground what is the slope of graph (I’m so sorry I don’t have a picture)
Answer:
C.) -5
Step-by-step explanation:
The slope formula is rise/run, in other words, rise divided by run or the y variable divided by the corresponding x variable.
In this question, we are told that the y-value is "20 feet above" meaning this is the rise and the run is "4 feet from"
To find the slope all we have to do is divide 20 by 4 giving us 5. Since the ladder is going down we know that we have to place a negative sign before the slope giving us our final answer of -5
while shooting Baskets at a basketball hoop you make 36 out of 80 shots your friend makes 43.75 percent of the shots who made a higher percent
Answer:
The 'your friend' made a higher percentage of shots .
Step-by-step explanation:
80 - 43.75 = 36.25
80 is the total amount
36 (36.25) is YOUR amount
43.75 is 'your friends' amount
and with the equation I shows at the top 'your friend' has the higher number of percent from the shots compared to you
I hope this helps!

(6y + 10) - (2y + 3)
Answer:
4y+7
Step-by-step explanation:
First, remove the unnecessary parenthesis. Add like terms (In this case it’s y) So it will be 6y-2y. Which gives you 4y. And then after that 10-3, which gives you 7. So your final answer is 4y+7!!

please help me I'm confused
Answer: The correct answer is 8^2 or 64
Step-by-step explanation: Can I please get the brainliest answer.
Answer:
8²
Step-by-step explanation:
When we divide numbers with exponents that have the same bases, we can just subtract the exponents. So, 8^9/8^7 equals 8^(9-7) = 8^2 (Which equals 64, but it isn't a power).
Evaluate f(x)=7x+7 when x=-9
Answer:
-56
Step-by-step explanation:
f(x) = 7x + 7
x = -9
We meed to plug in x = -9 into the first equation:
f(-9) = 7(-9) + 7
We can open up the parentheses:
f(-9) = -63 + 7
And then simplify:
f(-9) = -56

8r+7t
Step-by-step explanation:
Answer:
An equivalent expression to 12r + t - 4r + 6t is 8r + 7t
Step-by-step explanation:
You just need to combine like-terms together, 12r and -4r, t and 6t, to get to 8r + 7t.
What is the mode and range of the data set
18,22,20,21,24
Answer:
There is NO mode.
The range is 6.
Step-by-step explanation:
Mode is the most frequent number and in this case there are no repetitive numbers.
Range is the Max Number minus the Minimum Number. So in this case 24-18 which equals 6.
Anu borrowed Rs 4000 from a bank at 7 % per annum for 2 years. She then lent this amount to Nidhi at 9 % per annum for the same period. How much did Anu gain in this transaction?
Step-by-step explanation:
p- 4000
r- 7
t-2years
SI- P×r×t/100
SI-4000×7×2/100
SI- 4000×14/100
SI- 56000/100
SI- 560
so anu give = p+ SI
= 4000+560
= 4560 ₹
p- 4000
r- 9
t-2 years
SI- P×r×t/100
SI- 4000×9×2/100
SI- 4000×18/100
SI- 72000/100
SI- 720
so nidhi give= p+SI
= 4000+720
= 4720

(8x + 9) + (–6x – 1)
Answer:
5
Step-by-step explanation:
Simplifying
(8x + 9) + -1(6x + -1) = 0
Reorder the terms:
(9 + 8x) + -1(6x + -1) = 0
Remove parenthesis around (9 + 8x)
9 + 8x + -1(6x + -1) = 0
Reorder the terms:
9 + 8x + -1(-1 + 6x) = 0
9 + 8x + (-1 * -1 + 6x * -1) = 0
9 + 8x + (1 + -6x) = 0
Reorder the terms:
9 + 1 + 8x + -6x = 0
Combine like terms: 9 + 1 = 10
10 + 8x + -6x = 0
Combine like terms: 8x + -6x = 2x
10 + 2x = 0
Solving
10 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + 2x = 0 + -10
Combine like terms: 10 + -10 = 0
0 + 2x = 0 + -10
2x = 0 + -10
Combine like terms: 0 + -10 = -10
2x = -10
Divide each side by '2'.
x = -5
Simplifying
x = -5

Solve the system of linear equations below: y= 4x-9 y= x-3
[tex] \begin{cases} y = 4x - 9 \\ y = x - 3 \end{cases}[/tex]
We can combine both equations
[tex]4x - 9 = x - 3[/tex]
Solve the equation.
[tex]4x - x = 9 - 3 \\ 3x = 6 \\ x = \frac{6}{3} \longrightarrow \frac{2}{1} \\ x = 2[/tex]
Then we substitute the value of x in any given equations which I will be substituting in the second equation
[tex]y = x - 3 \\ y = 2 - 3 \\ y = - 1[/tex]
Therefore, from x = 2 and y = -1, the solution is (2,-1)
Answer Check
Substitute the value of x and y in both equations.
First Equatio
[tex]y = 4x - 9 \\ - 1 = 4(2) - 9 \\ - 1 = 8 - 9 \\ - 1 = - 1[/tex]
Second Equation
[tex]y = x - 3 \\ - 1 = 2 - 3 \\ - 1 = - 1[/tex]
Both equations are true for (2,-1).
Answer[tex] \begin{cases} x = 2 \\ y = - 1 \end{cases} \\ \sf \underline{coordinate} \\ (2,-1)[/tex]
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x - 9 → (1)
y = x - 3 → (2)
Substitute y = 4x - 9 into (2)
4x - 9 = x - 3 ( subtract x from both sides )
3x - 9 = - 3 ( add 9 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = 2 - 3 = - 1
solution is (2, - 1 )

Your mom sends you to the store to buy some meat for
your birthday party.
She gives you $65 and wants you to spend it all on
exactly 15 pounds of meat.
Chicken is $3 a pound.
Steak is $5 a pound.
Is her request possible? If so, how much of each meat
would satisfy your mom's request?
Answer: the request is possible. you could buy 10 pounds of steak, for $50, which leaves you with $15 dollars left over. you could buy 5 pounds of chicken for $15. leaving you with no extra money and 15 pounds of meat.
Step-by-step explanation:
10 pounds of steak for 5 dollars each = $50
$65 - $50 = $15
5 pounds of chicken for 3 dollars each = $15
$15 - $15 = 0 10 pounds + 5 pounds = 15 pounds
Answer:Yes
Step-by-step explanation:
If you want to buy 13 pounds of steak then you spend all of your money
