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

F= first car
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

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).

Lourdes plans to jog at least 1.5 miles. Write and solve an inequality to find x, the number of hours that Lourdes will have to jog..

Answers

Answer:

An inequality compares two or more variables by using the <, >, ≤, or ≥ signs.

The number of hours Lourdes will have to jog is 0.4 hours

From the given parameters:

Lourdes plans to jog for at least a distance of 1.5 miles

If Lourdes can jog averagely at the speed of 3.75 mph

Then,

the inequality that can represent the information can be written as:

= 1.5 miles ≤ 3.75 (x) miles/hour

Solving the inequality;

= 1.5 ≤ 3.75 (x)

Making (x) the subject of the formula, we have:

x =  0.4 hours

Therefore, we can conclude that the number of  hours lourdes will have to jog is 0.4 hours

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.

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]

Let f(x)=8x−6. What is the value of f(12)?

Answers

Answer:

f(12) = 90

Step-by-step explanation:

This is more of a notation problem than anything else.

The x on the left means that the variable is x. That sounds weird I know, but it starts out this way.

f(variable) =  8*variable - 6

Where you see the word variable, you put the letter x and that gives you the question.

f(x) = 8*x - 6

That is math shorthand for whatever you see on the left, like an x or in this case 12, you put the value 12 in for x on the right. It will look like this.

f(12) = 8*12 - 6   Now it just becomes a calculator problem.

f(12) = 96 - 6

f(12) = 90

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
