Answer: 30.6 in the moon
6. What type of slope does the equation
7x + 3y = 15 have? (Hint: convert to slope
intercept form.)
A) positive
B) Negative
C) Zero
D) Undefined
We can convert the line 7x + 3y = 15 into the slope-intercept form (y = mx + c) by making y the subject of the equation. In this form the coefficient of x (m) is the slope.
Since 7x + 3y = 15
3y = -7x + 15
y = - ⁷/₃x + 5
∴ the slope is NEGATIVE.
Check your answer:
A line with a negative slope is highest to the left and lowest to the right. This is because when x values increase, the y values decrease, and when x values decrease, y values increase (the two variables are negatively related). If we graph the line this should be true, and it is.
can someone please help
Answer:
the slope is -8

What type of polynomial is P(x)=x3−1?
A. cubic
B. quintic
C. linear
D. quartic
Answer:
A.
Step-by-step explanation:
Cubic because the highest exponent is 3.
The classification of the polynomial P(x) = x^3−1 by degree is; Cubic. Hence, option A is correct.
What are polynomials forms?Generally, polynomials take the form,
P(x) = ax^n + bx^(n-1) + cx^(n-2).... + z
where:
a, b....= arbitrary constants
x = variable
n = highest power of the variable in the polynomial
The given polynomial is P(x) = x^3−1
The classification of the polynomial P(x) = x^3−1 by degree is; Cubic.
Cubic function is one that has the highest exponent is 3.
Hence, option A is correct.

Each letter of L I T T R E L L is written on a card. The cards are placed in a basket. Find each probability if Elsa selects a card, leaves it out, and then selects another card.
7. Is this an independent or dependent event? Explain: ______________________________ _____________________________________ _____________________________________
8. What is the probability of selecting a T and then an E?
9. What is the probability of selecting a T, and then another T?
10. P(E, then I)?
Step-by-step explanation:
7. I believe it's independent because it makes sense and if it was dependent it wouldn't make senses.
8.For T you have 2 (Ts) so that give you a 2/8= 25% so you would basically make those Ts disappear and focus on 1 out of 6 and you'd get a 16.67% chance
9. 14.2857%
10. I don't understand ;-; am I suppose to multiply or see the chance if % it would get

Enter the number that belongs in
the green box

Answer:
58°
Step-by-step explanation:
in ΔABD
∠ADB = 32°
∠DBA = 90°
∠BAD = 180° - (32 + 90)
∠BAD = 58°
As ΔBAD ≅ ΔBCD
∠BAD = ∠BCD
So ∠BCD = 58°
Jack’s recipe calls for One-half teaspoon of baking powder. He cannot find the One-half teaspoon measuring spoon. Instead, Jack uses the One-eighth teaspoon measuring spoon to add Three-eighths teaspoon of baking powder. Which statement is true? Jack should stop adding baking powder because One-eighth equals . Jack should add more baking powder because Three-eighths is less than One-half. Jack should add more baking powder because Five-eighths is less than One-half. Jack has added too much baking powder because is greater than .
Answer:
Jack should add more
Step-by-step explanation:
Because four eighth is half
And he only added 3/8
So when he adds 1/8 more the sum becomes 4/8
4/8=1/2

.. ......................
the shopkeeper sold a laptop having its cost price rupees 25000 at a profit of 25% find its selling price
Answer:
Let's see what we have here. A shopkeeper sold Item X for a his selling price (SP).
Let SP = x
Since the question says that Profit is 25% of the selling price, we have:
Profit = 25% SP = 0.25x
Now, we already know that:
Profit = SP - Cost
This part is the catch. To find out how much Item X originally cost,
Cost = SP - Profit = x - 0.25x = 0.75x
Now that we know the original cost of Item X, we can easily calculate the Real profit % using this formula:
= (Profit/Cost)*100
= (0.25x/0.75x)*100
= 33%
And there you have it. Hope I explained it clear enough.
Answer:
Step-by-step explanation:
Cost price = CP = ₹ 25,000
Profit% = 25%
Selling price = SP
[tex]SP =\dfrac{100+profit}{100}*CP\\\\\\=\dfrac{100+25}{100}*25000\\\\=\dfrac{125}{100}*25000[/tex]
= 125 * 250
= ₹31250
