if f(x)=8x+3 what is the value of x when f(x) =19
Answer:
2
Step-by-step explanation:
plug in f(x)
19=8x+3
subtract 3 from both sides
16=8x
divide by 8
2=x

Answer:
A. For each input value, x, there is exactly one output value, y.
Step-by-step explanation:
A function always have exactly one output value (y-value) that is related or assigned to each input value (x-value), however, two different x-values can have the same y-value.
In the graph given, although two different values have the same y-value, every x-value has exactly one y-value corresponding to it. No x-value has two different y-values.
Therefore, the graph represents a function.

Jean's bedroom is 13 feet by 13 feet. She has chosen a carpet which costs $28.60 per square yard. This includes installation.
Answer:
$528.8
Step-by-step explanation:
Given data
Dimension
13 feet by 13 feet
1 ft =4.3 yard
Area= 4.3^2
Area= 18.49 yard
cost of carpet
1 yard= $28.60
18.49 yard= x
cross multiply
x= 18.49*28.60
x=$528.8
Hence the cost to cover the room is $528.8
What is −3x+4y=−16 in slope-intercept form?
Answer:
y=3/4x-4
Step-by-step explanation:
First you put x to the other side of the equation, so you have 4y = 3x-16. Next you need to get y alone so you get 4y/4=y. But, you need to do this to both sides of the equation, so you do 3x-16/4=3/4x-4. All in all, your slope-intercept form is y=3/4x-4.
Is x = 5 a solution to the equation 19 - x= 14?
A. Yes, because 19 - 5 = 14 is not true.
B. No, because 19 - 5 = 14 is not true.
C. Yes, because 19 - 5 = 14 is true.
D. No, because 19 - 5 = 14 is true.
Answer:
C.
Step-by-step explanation:
If you plug in the value of x (5) into the equation you get...
19-5=14
Then solve.
14=14
Is 14=14?
Yes!
Meaning that it is a solution.
Hope this helps!
Write down in terms of n an expression of the nth terms?
Answer:
A. nth term = 4 + (n - 1) -3
B. nth term = -7 + (n - 1) -5
Step-by-step explanation:
A. 4, 1, -2, -5, -8
First term, a = 4
Common difference, d = 1 - 4 = -3
nth term = a + (n-1)d
nth term = 4 + (n - 1) -3
B. -7, -12, -17, -22, - 27
First term, a = -7
Common difference, d = -12 - (-7)
= -12 + 7
= -5
nth terms = a + (n - 1)d
nth term = -7 + (n - 1) -5
Noah's oven thermometer gives a reading that is 2% greater than the actual temperature.
If the actual temperature is 325°F, what will the thermometer reading be?
Round your answer to the tenths (first) decimal place.
Do not include units (°F) in your answer.
PLS HELP
357 I think is the right answer.Since the thermometer reading was 7°F greater than 350. The thermometer reading is 359+7=357

1. The ratio of boys to girls is 4/5. If there
are 24 boys, how many girls are there?
Given:
The ratio of boys to girls is [tex]\dfrac{4}{5}[/tex].
Number of boys = 24
To find:
The number of girls.
Solution:
We have,
Boys: Girls = 4:5
Let the number of boys be 4x and number of girls be 5x.
[tex]4x=24[/tex]
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
Now,
Number of girls = [tex]5x[/tex]
= [tex]5(6)[/tex]
= [tex]30[/tex]
Therefore, the number of girls is 30.

y=[?]°
Answer:
Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.
48 + 90 + y = 180
138 + y = 180
-138 + 138 + y = 180 - 138
y = 42°
