Given f (x) = 3x - 8 find x if f(x) = -14
Answers
Answer:
[tex]x=-2[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=3x-8[/tex]
And we want to solve for x if f(x) is -14.
So, substitute -14 for f(x):
[tex]-14=3x-8[/tex]
Add 8 to both sides:
[tex]-6=3x[/tex]
Divide both sides by 3:
[tex]x=-2[/tex]
And we're done!
Answer:
The value of x is -2 .
Step-by-step explanation:
You have to solve it by doing comparison :
[tex]f(x) = 3x - 8[/tex]
[tex]f(x) = - 14[/tex]
[tex]3x - 8 = - 14[/tex]
[tex]3x = - 14 + 8[/tex]
[tex]3x = - 6[/tex]
[tex]x = - 6 \div 3[/tex]
[tex]x = - 2[/tex]
What are the coordinates of the point that divides the segment into a 3:2 ratio?
Answers
Answer:
(–2.2, –1.2)
Step-by-step explanation:
o divide the segment into a 3:2 ratio, we need to divide the segment into five identical parts, and find the point that divides the segment into 3/5 and 2/5. To do this we have to calculate the distance between the two points of the segment, in x and y, we can do this by just subtracting the two "y" coordinates and the two "x" coordinates:
Δy=║-4-3║=7
Δx=║-1-(-4)║=3
Then we divide those differences by 5.
7/5=1.4
3/5=0.6
and now, we multiply those results by 3 and subtract them or add them from the coordinates of the point G (subtract them from the coordinate y and add it to the coordinate x, because we are moving down and right).
Px=-4+3*0.6=-2.2
Py=3-3*1.4=-1.2
so the coordinates of the point we are looking for (which I called "P") are:
P(-2.2, -1.2).

Answers
Answer:
Mylar Ballons: 11
Latex Balloons: 7
Step-by-step explanation:
1.25 times 11 equals 13.75
.75 times 7 equals 5.25
5.25+ 13.75 equals 19

Suppose we get 24 inches of snow tomorrow. Warm weather comes the next day. For the next several days it stays warm and begins to melt the snow. If the snow melts at 2.5 inches a day, how much snow will be left on the ground after 7 days?
Answers
Answer:
6.5 inches
Step-by-step explanation:
Suppose we get 24 inches of snow tomorrow
The next day becomes warm.
The weather remains warm for the next several days.
The snow melts at 2.5 inches a day
Therefore the amount of snow that will be left after 7 days can be calculated as follows
= 2.5 ×7
= 17.5
Since the initial amount of snow was 24 inches then,
24 -17.5
= 6.5
Hence the amount of snow that will be left on the ground after 7 days is 6.5 inches
Two cities are 243 miles apart
It takes a train 4 hours to travel between the two cities at a constant speed.
A car travels between the two cities at a constant speed of 65 miles per hour.
Which is traveling faster, the car or the train? Explain your reasoning.
Answers
Answer:
The car is travelling faster.
Step-by-step explanation:
Given that,
Distance between two cities = 243 miles
Time of train = 4 hours
Speed of car = 65 miles/hours
We need to calculate the speed of train
Using formula of speed
[tex]v=\dfrac{d}{t}[/tex]
Where, d = distance
t = time
Put the value into the formula
[tex]v=\dfrac{243}{4}[/tex]
[tex]v=60.75\ miles/ hours[/tex]
Hence, The car is travelling faster.

Step-by-step explanation:
2 servings is 1/5 of 10 servings, so the amount of water needed is 1/5 of 8 cups.
(1/5)(8 cups) = 8/5 cups = 1.6 cups
1.6 cups of water are needed for 2 servings.

3x - 8 = 15
Answers
Answer:x = 7.667
Step-by-step explanation:
3x - 8 = 15
+ 8 = 23
3x = 23
divide 3 by 3 and 23 so you get x by itself
answer = 7.667
Answer:
x = 7.667
Step-by-step explanation:
3x - 8 = 15 (Rearrange expression)
-8 - 15 = -3x (Combine like terms)
-23 = -3x (Divide)
x = 7.667
Give the equation of a line that goes through the point ( − 24 , 2 ) and is perpendicular to the line 8 x + 3 y = − 6 . Give your answer in slope intercept form
Answers
Answer:
[tex]y=\frac{3}{8}x+11[/tex]
Step-by-step explanation:
To find a line that is perpendicular to 8x + 3y = -6 and goes through (-24, 2), lets first find what the line's slope would be.
We can find this by finding the slope of 8x + 3y = -6 and taking the negative reciprocal of it.
We can find the slope of that line by putting it in slope-intercept form:
8x + 3y = -6
Subtract 8x from both sides.
3y = -6 - 8x
Divide both sides by 3.
[tex]y=-\frac{6}{3}-\frac{8}{3}x[/tex]
[tex]y=-\frac{8}{3}x-2[/tex]
So the slope of that line would be -8/3.
The negative reciprocal of -8/3 would be 3/8.
Now we know that the new line would have to pass through the point (-24, 2). We can use this point and write the equation in point-slope form:
[tex]y-2=\frac{3}{8}(x+24)[/tex]
Now lets change this into slope-intercept form. Add 2 to both sides.
[tex]y=\frac{3}{8}(x+24) +2[/tex]
Distribute the 3/8.
[tex]y=\frac{3}{8}x+9+2[/tex]
Simplify.
[tex]y=\frac{3}{8}x+11[/tex]
And now we have our equation in slope-intercept form.
I hope you find this helpful.

It’s bath time while filling the tub dad used the last capful of bubble bath.after doing quick search for more to buy he notices that he can get 36oz for $3.79 or 24 oz for $2.89. Which of these options is the better deal ?
Answers
If you divide the price by the number of ounces, you will get how much you are paying for a single ounce.
[tex]\frac{3.79}{36}[/tex] ≈ 0.11 dollars per ounce
[tex]\frac{2.89}{24}[/tex] ≈ 0.12 dollars per ounce
As you can see, you are paying about 0.01 dollars more for every ounce of bubble bath in the second option. So you are better off buying 36 ounces for 3.79 dollars.
You can also do this buy dividing ounces by dollars.
[tex]\frac{36}{3.79}[/tex] ≈ 9.5 ounces per dollar
[tex]\frac{24}{2.89}[/tex] ≈ 8.3 ounces per dollar
Again, you can see that you get about 1 more ounce for every dollar you pay in the first option. So 36 ounces for 3.79 dollars is the way to go.

Chen is baking muffins and banana bread for a brunch buffet. He needs 3 and one-fifth cups of flour to make the muffins and 3 and two-thirds cups of flour to make the banana bread. Which is the best estimate of the number of cups of flour that Chen needs to bake both recipes? 6 cups of flour 7 cups of flour 8 cups of flour 9 cups of flour
Answers
7 cups of flour
reason:
to find how much flour is needed, first you need to combine the two fractions.
to add the fractions, you first have to find a common denominator, which in this case is 15
multiply 1/5 by 3 to get 3/15, and 2/3 by 5 to get 10/15. combined, this is 13/15
since the answer is looking for the best estimate, you take the overall amount of flour, which would be 6 13/15, which is closer to 7 cups than 6
(I may be wrong this is just how I did it)
Answer:
The answer would be b. 7 cups of flour.
