Answer:

plz give me BRAINLIEST answer

Step-by-step explanation:

For this case we observe that the time varies linearly with the obtained qualification.

The equation of the line can be obtained as follows

g-go = m (t-to)

where (go, to) are points that belong to the line.

To form the equation you need two points. These points are

(g1, t1) = (0,0)

(g2, t2) = (6.5.84)

Then, substituting, the equation of the line is

m = (84-0) / (6.5-0) = 84 / 6.5 = 12.923

g-0 = (12,923) * (t-0)

Rewriting.

g = 12.923t

The slope of the line is

m = 12,923

Pls help for number 6

A: 45x + 30y = 1350
Since we don’t know how many adults and children are in the group, we use x and y

b: x-intercept= 30 y-intercept=45
To find the x-intercept you need to isolate the variable. 45x/45 = x
Then you do the same thing to the other side. 1350/45 = 30
So x=30
Same thing with the y-intercept.
30y/30 = y 1350/30 = 45
y=45 (Not really sure what it means by “what they represent” but I thinks it’s that there are 30 adult tickets and 45 children tickets )

c: so our points are (30,0) and (0,45) so you would graph that.
To find how many children tickets were bought if there were 20 adult tickets just look at the photo I put. I don’t know how to explain this.


Hope this helps

-1/3x+2x=3 3/4 what does the variable represent?
svet-max [94.6K]
Start off by combining like terms on the LHS (the terms with x in them).

So we get \frac{-1}{3}x+2x= \frac{-1}{3}x+ \frac{6}{3}x= \frac{-5}{3}x

Replacing this result with what we had before on the LHS, we get \frac{-5}{3}x=3 \frac{3}{4}= \frac{9}{4}

⇒Solve for x (divide both sides \frac{-5}{3})
⇒Don't forget about reciprocity rules when dividing.  This is the same as multiplying both sides by \frac{3}{-5}

⇒x= \frac{9}{4}( \frac{3}{-5})

⇒x= -\frac{27}{20}=-1\frac{7}{20} ***This is a proper fraction

At a certain real estate firm, realtors selling homes receive a commission of: 7% for the first $100,000 of the selling price, a
scoray [572]

Answer: The actual price of house sold at $109000.

Step-by-step explanation:

Since we have given that

Selling price = $100000

Rate of commission = 7%

So, Amount of commission would be

\dfrac{7}{100}\times 100000\\\\\=\$7000

Total commission = $7540

So, Remaining amount of commission would be

\$7540-\$7000\\\\=\$540

Rate of commission exceeding $100000 = 6%

Let the selling price of house be 'x'.

According to question,

\dfrac{6}{100}\times x=540\\\\0.06x=540\\\\x=\dfrac{540}{0.06}\\\\x=\$9000

Hence, the actual price of house sold at

$100000+$9000=$109000.
