Given: -4x + 2y = 8
Prove: y = 4 + 2x​

Answer:

4 [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

When adding fractions, you want to make the denominators of the fraction the same. To do this, we can multiply both the numerator and denominator of 3/4 by 3. When changing either a denominator or numerator in a fraction, you must do the same thing to the numerator as the denominator.

Now we have [tex]\frac{3\cdot3}{4\cdot3} = \frac{9}{12}[/tex]. To add 9/12 and 5/12, we keep the denominator the same, and add the numerators, getting [tex]\frac{9+5}{12} =\frac{14}{12}[/tex]. This is greater than 1, so we can take 12/12 from 14/12, and make it [tex]1 \frac{2}{12}[/tex]. If we then add 3, we get [tex]4 \frac{2}{12}[/tex], which simplifies to [tex]4 \frac{1}{6}[/tex]

Answer:

The equation is [tex]y=-\frac{1}{3}x+1[/tex]

Step-by-step explanation:

You have the y-int, so you just need to find the slope, which is the negative reciprocal of A/B since it is perpendicular. Plugging in the numbers gets you the above equation.

Answer:

A senior citizen will pay $4.97

Step-by-step explanation:

Mathematically, discount = discount percentage * marked price

Sales price = marked price - discount

In the question, marked price = $6

First, we have a discount of 10%, so therefore , the sales price will be;

$6 - (10/100 * $6 ) = $6 - $0.6 = $5.4

Now, a further 8% discount was given to senior citizens,

The extra discount for senior citizens is thus;

8/100 * 5.4 = $0.432

Amount to be paid by senior citizens = $5.4 - $0.432 = $4.968. which is $4.97 to the nearest cent

Answer:

the answer is $4.97.

solve for y first

2y=12-6×

divide each term by 2 and simplify

y=6-3x

Answer:

y=6-3x

Step-by-step explanation:

6x+2y=12

6x+2y=12 divide all by 2

3x+y=6 subtract 3x from both sides

y=6-3x

y=-2x+9

Answer:

Step-by-step explanation:

Note: Perimeter = sum of all the lengths of the shape.

In the case of a square, since all the sides are equal.

This means that if one side = 8x + 4, the perimeter would be 4 times 8x+4 since there are 4 equal sides in a square.

Perimeter = 4 ( 8x + 4)

Perimeter = 32x + 16

We also get told in the question that the perimeter = 80 inches.

Meaning that:

32x + 16 = 80

From here we can solve for x.

Subtract 16 from both sides:

32x = 80 - 16

32x = 64

Divide both sides by 32 to solve for x.

x = 64/32 = 2

Answer:

y=3

Step-by-step explanation:

Given problem:

What is the value of x = ?

 Solution:

Angle on a straight line is 180°

Sum of angles in a triangle  = 180°

Now to solve the problem, we need to find the two internal angles first;

  For the first one;

      let us say it is y;

              163 + y  = 180

                        y  = 180 - 163 = 17°

    For the second, assume it is z;

            69 + z = 180

                    z = 180 -69  = 111°

The sum of the internal angles of the triangle;

    y + z + 2x   =  180

     17 + 111 + 2x  = 180

                    2x  = 180 - 128

                     2x  = 52

                       x = [tex]\frac{52}{2}[/tex]   = 26

The value of x is 26

157 = .166 x

157/0.166 = x

945.78313253 = x

157 is 16.6% of 945.78313253, which rounds to 946.

The 157 is approximately 16.6% of 945.78313253012 rounded to the nearest decimal place.

To find the number that 157 is 16.6% of,  set up the following equation:

16.6% = 0.166 (since percentages expressed as decimals)

0.166 × x = 157

To isolate x, we divide both sides of the equation by 0.166:

x = 157 / 0.166

Simplifying the division:

x ≈ 945.78313253012
