Answer:

Graph 3 represents the solution to the system of equations.

Step-by-step explanation:

The given two linear equations of x and y are

y = 3x + 2 ........ (1) and

10x + 2y = 20 .......... (2)

Now, to solve those two equations let substitute the value of y from equation (1) to the equation (2).

Hence, 10x + 2(3x + 2) = 20

⇒ 16x = 16

⇒ x = 1

And from equation (1), y = 3x + 2 = 5

Therefore, the solution of the system of equations (1) and (2) are (1,5).

Therefore, graph 3 represents the solution to the system of equations. (Answer)

Leno4ka [110]

Answer:

You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference.

Help me answer the question j

The value of the expression is 252

Step-by-step explanation:

The expression that we have to evaluate in this problem is

$7x^2y$

And we have toe valuate it for

x = 3

y = 4

In order to evaluate the expression, let's substitute the values of x and y into it:

$7x^2y=7\cdot (3)^2\cdot (4)$

First, we calculate the square of 3, which is:

$3^2 = 3\cdot 3 = 9$

Substituting into the expression,

$7\cdot 3^2 \cdot 4 = 7\cdot 9 \cdot 4$

Now we multiply everything and we get:

$7\cdot 9 \cdot 4 = 252$

Evaluate each expression if a=2, b=3 and c=4<br><br> A.) 2a+4b-c<br> B.) 6(a+c)-b

djyliett [7]

Answer:

Step-by-step explanation:

A.) 2a+4b-c: Replacing a with 2, b with 3 and c with 4, we get:

2(2) + 4(3) - (4) = 4 + 12 - 4 = 12

B.) 6(a+c)-b: Replacing a with 2 and c with 4, we get 6(2 + 4) - 3.

The work inside parentheses should be done first, resulting in 6(6) - 3.

This comes out to 33.

Can you guys show me the proper steps for this ?

malfutka [58]

Answer:

C+11/c+9

Step-by-step explanation:

3c+33/3c+18 = c+11 / c+6

C^2+17c +66 = (c+6)(c+11)

C^2 +20c+99 = (c+11)(c+9)

So the given question becomes

{C+11/c+6} {(c+6)(c+11)/(c+11)(c+9)}

= c+11 /c+9

malfutka [58]

Answer:

$3+2(log_{2}(x+1) )$

Step-by-step explanation:

First simplify the quadratic present $8(x^{2}+2x+1)=8(x+1)^{2}$

$log_{2}8+log_{2}(x+1)^{2}$

⇒ $3+2(log_{2}(x+1) )$
