Answer:
a. -1
b. -3
Explanation:
To solve negative and positive numbers on the number line, we make a simple analogy. If we wanted to -3+2 for instance:
Imagine a customer placed an order for 3 bags of apples from your store but you are out of stock and only have 2 bags left. You then come to an agreement with the customer to send 2 bags now and send the remaining one later in the week when your stock arrives from your supplier. In this way, you are only able to send two bags which you have,+2, and then be owing the customer one bag left(-1) to deliver out of the three, -3.
To solve -2+1 on the number line, with -2 on the left side of 0(negative) on the number line and +1 on the right side of 0(positive), we use same analogy above.
-2+1= -1
Also using same analogy, -2+(-1)= -3
Note: +1×-1=-1

Solve for P.
-1 + 14 p = -435
Answer:
P = -31
Step-by-step explanation:
-1 + 14p = -435
Remove the -1 by adding it from both sides.
14p = -434
Remove the 14 by dividing it from both sides.
p = -434/14
p = -31
Answer:
-31
Step-by-step explanation:
-1+14p=-435
14p=-435-(-1)
14p=-435+1
14p=-434
p=-434/14
p=-31

HELP/ solve for x. Write your answer as "x=__"
Answer:
Hello! answer: x = 50
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees! so...
50 × 3 = 150 150 - 20 = 130
130 + 50 = 190 therefore x = 50 hope that helps!

In a specific arithmetic sequence, if -4 is the first term and 10 is the third term, which term is 157?
Step-by-step explanation:
everything can be found in the picture
The nth term of an arithmetic sequence is expressed as Tn = a +(n - 1)d. The 157th term of the sequence is 2180
Arithmetic sequenceThe nth term of an arithmetic sequence is expressed as:
Tn = a +(n - 1)d
where
a is the first termd is the common differencen is the number of termsIf -4 is the first term and 10 is the third term, then;
a = -4
a + d = 10
d = 10 - (-4)
d = 14
Determine the 157th term
T157 = -4 + (157 - 1)(14)
T157 = -4 + (156*14)
T157 = 2180
Hence the 157th term of the sequence is 2180

Answer:
AD = 6
Step-by-step explanation:

If two angles are both vertical and supplementary, can we determine the angles? Is it possible to be both vertical and complementary? If so, can you determine the angles? Explain how you know ASAP
Answer:
Two angles can be vertical and supplementary only if they add up to 90 degrees because there perpendicular.
Step-by-step explanation:
Answer:
90 + 90 = 180, 45 + 45 = 90
Step-by-step explanation:
Supplementary angles add up to 180 and to be vertical angles they need to be equal to each other so 2x = 180
x = 90
Hence both angles will be equal to 90
Complementary angles add up to 90 and as previously stated, to be vertical angles they need to be equal to each other so 2x = 90
x = 45
Hence both angles equal to 45

Describe the behavior of the function h around its vertical asymptote at x=-6.
Answer:
B
Step-by-step explanation:
One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .
When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.
Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B

Answer:
A. y = 2/5x - 2
Step-by-step explanation:
We can use the slope formula to find the slope of the line.
[tex]m=\frac{y_1-y_2}{x_1-x_2} \\m=\frac{-2-0}{0-5} \\m=\frac{-2}{-5}\\m=\frac{2}{5}[/tex]
Now we know that the slope of the line is 2/5. By looking at the graph, the line crosses the y-axis at the point (0, -2). Therefore, the equation of the line is y = 2/5x - 2.

Question 15 of 25 Given any triangle ABC with corresponding side lengths a, b, and c, the law of cosines states: 6. C A O A. b^2=a^2 +c^2 - 2 ac cos(B) so O B. b^2= a^2 +c^2 - 2bccos(A) O C. b2 = a^2 -c^2 -25ccos(5) OD. b^2=a^2 -c^2 -2bccos(C)
The correct representation of the law of cosines is A. c² = a² + b² - 2ab cos C.
What is the law of cosine?Let there is triangle ABC such that |AB| = a unit, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:
[tex]a^2 + b^2 -2ab\cos(\theta) = c^2[/tex]
(c is the opposite side to angle A)
We have been Given any triangle ABC with corresponding side lengths a, b, and c.
In the given triangle ABC, the sides are;
BC = a, AB = b and AC = c
Now we know as per the law of cosines for all three sides of the triangle;
c² = a² + b² - 2ab cosC
a² = b² + c² - 2bc cosA
b² = a² + c² - 2ac cosC
Therefore the correct representation of the law of cosines is A. c² = a² + b² - 2ab cos C.

Emil is cutting a 72-inch-long board and a 54 in long board into shelving. He wants to make as many shelves as he can while using up all the wood. What is the longest possible length of the shelves?
Answer: The longest possible length of the shelves = 18 inches
Step-by-step explanation:
Given: Lengths of two boards are 72-inches and 54 inches.
To make as many shelves as he can while using up all the wood we will find the longest possible length of the shelves = HCF ( 72, 54)
72 = 2 x 2 x 2 x 3 x 3
54 = 2 x 3 x 3 x 3
HCF(72,54) = 2 x 3 x 3 = 18
Hence, the longest possible length of the shelves = 18 inches
