Step-by-step explanation:

Hey there!

Here, The equations are:

y = x+1........(i)

4x + y = 6........(ii).

Now,

Putting equation (i) in (ii)

4x + y = 6

4x + (x + 1) = 6

5x + 1 = 6

5x = 6-1

$x = \frac{5}{5}$

Therefore, x= 1

Putting the value of x in equation (i).

y = x+1

y = 1+1

Therefore the value of y is 2.

Check:

y = x+1

2 = 1+1

2=2 ( True ).

Hope it helps....

Solve for x x^9=12^2x12^7

jekas [21]

Answer:

Step-by-step explanation:

Hi!

Here is your answer,

I will explain in step by step,

${x}^{9} = {12}^{2} \times {12}^{7}$

Here we can simplify this further using this law,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

So we will get,

${x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9}$

Since the powers are same we can cancel it out and we will get,

$x = 12$

(Hope this answer helped :))

Marcy has 150 to buy packages of hotdogs and hamburgers for her booth at the carnival. Grocery store she found packages of hotdo

bekas [8.4K]

Answer:

Part (A): The required equation will be: $6d+20b=150$

Part (B):The required equation will be: $d=\frac{150-20b}{6}$

Part (C):The required equation will be: $b=\frac{150-6d}{20}$

Step-by-step explanation:

Consider the provided information.

Let d represents number of packages of hot dogs and b represents the number of packages of hamburgers.

Part (a)

It is given that the cost of a package of hot dogs is $6 and cost of a package of hamburger is $20.

The required equation will be: $6d+20b=150$

Part (b) Solve the above equation for d.

Subtract 20b from both sides.

$6d=150-20b$

Divide 6 from both sides.

$d=\frac{150-20b}{6}$

The required equation will be: $d=\frac{150-20b}{6}$

Part (c) Solve the equation for b.

Subtract 6d from both sides.

$20b=150-6d$

Divide 20 from both sides, we get

$b=\frac{150-6d}{20}$

The required equation will be: $b=\frac{150-6d}{20}$

Write the standard form equation of the line through the given points. through (0.-4) and (-3,-2)

Alexxx [7]

Answer:

The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is $\frac{2}{3}x+y=-4$

Step-by-step explanation:

The standard form of equation is $Ax+By=C$

Finding slope

Using the given points (0,-4) and (-3,-2) we can find slope using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

$Slope=\frac{-2-(-4)}{-3-(0)}\\Slope=\frac{-2+4}{-3} \\Slope=-\frac{2}{3}$

Finding y-intercept

Using point (0,4) and Slope=-2/3 we can find y-intercept

$y=mx+b\\-4=-\frac{2}{3}(0)+b\\-4=0+b\\b=-4$

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

$y=mx+b\\y=-\frac{2}{3}x-4$

Now, standard form of equation will be: $\frac{2}{3}x+y=-4$

So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is $\frac{2}{3}x+y=-4$
