CAN ANYBODY HELP ME What is the 100th term in the sequence beginning with -45, -43, -41, -39, ...?
Group of answer choices
153
150
155
200
55
Answers
Answer:
153
Step-by-step explanation:
Since the given sequence is arithmetic because it has common difference.
-43-(-45) ,= -43+45 = 2
-41+43 = 2
-39+41 = 2
Therefore, the common difference is 2.
General Term
[tex] \displaystyle \large{a_n = a_1 + (n - 1)d}[/tex]
Since we want to find the 100th term, substitute n = 100.
We know common difference which is 2 and defined as 'd'; substitute d = 2
a1 means first term so:-
[tex] \displaystyle \large{a_{100}= - 45 + (100 - 1)2} \\ \displaystyle \large{a_{100}= - 45 + (99)2} \\ \displaystyle \large{a_{100}= - 45 + 198} \\ \displaystyle \large{a_{100}= 153}[/tex]

Which of following is the graph of y = -(x + 1)2 -3? o ty 2 ?? 덕 a -2 2 4 n DONE
Answers
Answer:
Neither of the graphs shown.
Step-by-step explanation:
Given the quadratic equation, y = - (x + 1)² - 3, where a = -1, and the vertex is the minimum value that occurs at point (-1, -3). It is easier to tell which graph corresponds to the given equation due to the coefficient, a. In quadratic fucntions, if a < 0, then it means that it is a downward-facing parabola. The value of a makes the parent function wider or narrower.
Also, the parabola is shifted 1 unit to the left, as defined by h = -1, and 3 units downward, defined by k = -3.
I'm not sure if there are other graphs as options. Since neither one of the graphs shown applies to the given quadratic equation, I'm including a screenshot of the correct graph for your reference, where it shows where the vertex is located, along with the y-intercept, (0, -4) -- just in case. Hopefully this helps.

Determine the intercepts of the line
x intercept : ?,?
y intercept: ?,?
Answers
Answer:
x-intercept: 3 or (3,0)
y-intercept: -10 or (0,-10)
Step-by-step explanation:
1. The intercepts of a graph are points at which the graph intersects with the x - or y-axis.
2. Given the information above, the line intersects with the x-axis at (3,0) and the y-axis at (0,-10).
Therefore, the x-intercept is 3 or (3,0) and the y-intercept is -10 or (0,-10).

A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas. During one particular week, the two cars went a combined total of 1700 miles, for a total gas consumption of 55 gallons. How many gallons were consumed by each of the two cars that week
Answers
S = second car
F+S =55
F= 55-S
20f+40s=1700
Using substitution method add the value of F to second equation
20(55-s)+40s=1700
1100-20s+40s=1700
1100+20s=1700
20s=600
s=30
So second car consumed 30 gallons of gas; first car consumed 25 gallons

Write a proportion you can use to solve.
Answers
1. The relationship between number of towers and number of customers is proportional.
2. When there are 576 towers, the number of customers that the company is 27648 customers.
How to calculate the value?From the information, the table shows the number of cell phone towers a company will build as the number of its customers increases.
When there are 5.25 towers, the customers are 252. This will be:.
= 252 / 5.25
= 48
Also, when it's 6.25, the customers are 300. This will be:
= 300/6.25
= 48
Therefore, there's a constant value of 48. This illustrates proportionality.
When there are 576 towers, the number of customers that the company have will be:
= 576 × 48
= 27648

Six times the quantity, x-2, is 24. Find the number
Answers
Answer:
x = 6
Step-by-step explanation:
it states 6 times the quantity x - 2, so the expression would be 6 ( x - 2 ) = 24. first multiply because you cannot add or subtract unlike terms. so 6 multiplied by x and -2, the expression would be (6x - 12) = 24. add 12 to 12 so you cancel the coefficient. but when adding to the constant add to the sum. now it is 6x = 36. since 6x is multiplication, divide 6x by 6 to isolate the variable, but divide the answer, 36 divided by 6 is 6. therefore x = 6. hope this helps
