How do u Mulitply a Coefficient

1 answer:

Alex73 [517]3 years ago

6 0

Answer:

To multiply terms, multiply the coefficients and add the exponents on each variable. The number of terms in the product will be equal to the product of the number of terms.

Step-by-step explanation:

For example, 3 is the coefficient in 3x. Rather than using a multiplication sign between 3 and x, the number is just written in front of a variable, which means that the 3 and x are multiplied together. Instead of writing a + a + a + a, you can express it as 4a, with 4 being the coefficient.

The total cost for Sophia to build b birdhouses is represented by the function f(b)=3.5b+24.

dybincka [34]

Answer: For each birdhouse built, the total cost increases by $3.50.

Step-by-step explanation:

Given: The total cost for Sophia to build b birdhouses is represented by the function $f(b)=3.5b+24$

We can see in the function 3.5 is multiplied to b, so when b increases , f(b) increases by 3.5.

$f(1)=3.5(1)+24=3.5+24=27.5$

$f(2)=3.5(2)+24=7+24=31$

$f(3)=3.5(3)+24=10.5+24=34.5$

and $f(2)-f(1)=f(3)-f(2)=3.5$

Therefore, the value of 3.5 represents that for each birdhouse built, the total cost increases by $3.50.

A box office sells balcony seats, ground-level seats, and VIP passes for shows on tour. The table shows the numbers of each type

Lana71 [14]

Answer:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

Step-by-step explanation:

Let the price of one Balcony seat = $ $x$

Let the price of one Ground level seat = $ $y$

Let the price of one VIP seat = $ $z$

As per the given table:

$135x+280y+29z=37170 ....... (1)\\150x+270y+58z=42240 ....... (2)\\130x+265y+29z=35570 ....... (3)$

Multiplying (1) with 2 and subtracting (2) from it:

$120x+290y=32100 \\12x+29y=3210..... (4)$

Subtracting (3) from (1):

$5x+15y=1600\\x+3y=320 ....... (5)$

Multiply equation (5) with 12 and subtracting (4) from it:

$7y=630\\\Rightarrow y =\bold{90}$

By equation (5), putting value of $y$ :

$x=\bold{50}$

By equation (1), putting the values of $x, y:$

$135\times 50+280\times 90+29z=37170\\\Rightarrow 29z=37170-31950\\\Rightarrow 29z=5220\\\Rightarrow z =\bold{180}$

Therefore, the answers are:

The price of one Balcony seat = $50

The price of one Ground level seat = $90

The price of one VIP seat = $180

(c) If 2a + 7b = 11 and ab = 2, find the value of 4a2 + 49b2.

Mademuasel [1]

I hope this helps you

take both of sides paranthesis square

(2a+7b)^2=(11)^2

4a^2+2.4a.7b+49b^2=121

4a^2+49b^2+56.2=121

4a^2+49b^2=9
