Step-by-step explanation:
For which equations is 8 a solution? Select the four correct answers.
x + 6 = 2
x + 2 = 10
x minus 4 = 4
x minus 2 = 10
2 x = 4
3 x = 24
StartFraction x Over 2 EndFraction = 16
StartFraction x Over 8 EndFraction = 1
Answer:
The answers include
x + 2 =10
x - 4 = 4
3x = 24
Start Fraction x Over 8 End Fraction = 1
Step-by-step explanation:
x + 2 = 10; 8 + 2 = 10
x - 4 = 4; 8 - 4 = 4
3x = 24; 3(8) = 24
Start Fraction x Over 8 End Fraction = 1; 8/8 = 1
Equations with solution x = 8 are
x + 2 = 10,
x minus 4 = 4,
3x = 24,
Start Fraction x Over 8 End Fraction = 1
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given equations
x + 6 = 2
⇒ x = 2-6
⇒ x = -4
x + 2 = 10
⇒ x = 10 - 2
⇒ x = 8
x minus 4 = 4
x - 4 = 4
⇒ x = 4 + 4
⇒ x = 8
x minus 2 = 10
x -2 = 10
⇒ x = 10+2
⇒ x = 12
2x = 4
⇒ x = 4/2
⇒ x = 2
3x = 24
⇒ x = 24/3
⇒ x = 8
Start Fraction x Over 2 End Fraction = 16
x/2 = 16
⇒ x = 2(16)
⇒ x = 32
Start Fraction x Over 8 End Fraction = 1
x/8 = 1
⇒ x = 8(1)
⇒ x = 8
Hence, equations
x + 2 = 10,
x minus 4 = 4,
3x = 24,
Start Fraction x Over 8 End Fraction = 1
have 8 as solution.

For this exponential function what is the output value (y) when the input value (c) is 3?
Answer:
y = 40
Step-by-step explanation:
Given, y = 5 * 2^x
If x = 3, y would be:
Substitute the value of x into the given function.

Noah wrote that 6+6 =12. Then he wrote that
6+6 -n =12 - n. Are his equations balanced? Explain.
Answer:
Hs equations are balancedStep-by-step explanation:
To check whether both equations are balanced, we will simplify
6+6 -n =12 - n
Add n to both sides of the equation using additive property
6+6-n+n = 12-n+n
6+6 +0 = 12+0
6+6 = 12 (This gives the other equation)
Since they are both equal, this shows that the equations are balanced

Paige is a graphic designer who makes logos for companies. She makes a design for a logo, which is in the shape of a square. The design of this logo is drawn on the coordinate plane as square ABCD. She then dilates this logo by a scale factor of 2, forming square A'B'C'D'. She realizes that she needs a much bigger design and so further dilates this transformed square by a scale factor of 3 to form A"B"C"D". What are the coordinates of vertex A' and vertex C"?

Please hurry; Which function increases the fastest? A. y 5 14x B. y 5 23 · 17x C. y 5 120x D. y 5 2275x^x
a y = 14^x
b y = -3 (17)^x
c y = 120x
d y = -275x
Answer: y = 14^x
Step-by-step explanation:
Here the options are:
a y = 14^x
b y = -3*(17)^x
c y = 120x
d y = -275x
to see which function increases the fastest (or which function is steeper) we need to look at the first derivations of each one of these, and see which one is larger for every value of x:
the derivations are:
a y = x*14^(x - 1)
b y = -x*3*(17)^(x - 1)
c y = 120
d y = -275
So we can already discard options c and d, because have constant rate of change.
Then we keep options a and b.
Always when we have an exponential function, like a^x and b^x
The one with the larger base will be steeper.
So if a > b, then:
a^x is steeper than b^x
In this case, the function:
y = -3*(17)^x
has a larger base, but, this function is negative.
This means that as x increases, our function will decrease, then this function will not "increase the fastest" (because it does not increase)
Then the left option (a: y = 14^x)
Will be the correct one.
(this will happen after some value of x, because two of the options have constant derivatives, these may be steeper for smaller values of x, and as x increases, we will see that y = 14^x is the one that increases the fastest)
What is the scale factor of this dilation?
A:2/3
B:1 1/2
C:3
D:5

Step-by-step explanation:
Two candles were lit and are burning. Candle A has
an initial height of 10 inches and burning down at a
rate of 1.5 inches per hour. Candle B is burning down
at a rate of 0.5 inches per hour and has an initial
height of 6 inches. Let t represent time in hours and
h represent the total height of the candle.
Answer:
A - 6 hours and 40 minutes
B - 12 hours
Step-by-step explanation:
Candle A - After 6 hours: the candle will be 1 inch tall, because 6 times 1.5 = 9. You need an extra 40 minutes for the candle to burn completely, because 10/1.5 = 6 and 2/3
Candle B - After 12 hours, the candle will be completely burned, because 6/.5 = 12.
Equation - Initial height/inches burned per hour = time it takes for cnadle to burn down completely

Jessica is selling books during the summer to earn money for college. She
earns a commission on
each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(X) = 10x - 30, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply.
A. She can earn $10 per week even if she does not knock on any
doors.
B. She will lose $10 per week if she does not knock on any doors.
C. If she does not knock on any doors at all during the week, she will
lose $30.
D. Her expenses are $30 per week.
Jamil makes a drink by mixing
1 part of orange squash with 9 parts of water.
He uses 750 millilitres of orange squash.
Jamil is going to put the drink he has mixed into 1 litre bottles.
Work out the greatest number of 1 litre bottles that Jamil can completely fill.
Answer:
7 bottles
Step-by-step explanation:
first, calculate the volume of the total ammount of soloution
750ml + 9(750ml)=7500ml
then divide by 1000 to put the total into litres
7500/1000=7.5L
7.5L goes into 1L exactly 7 times with a remainder of 500ml as the bottles are required to be completely full
