Yvonne had 15 hair accessories and gave away 5. Then she went to the
store and found a great deal which allowed her to buy two for the price of
one. She picked up 8 new accessories. How many does she have now?

Answer:

y = 4x + 7

Step-by-step explanation:

Isolate the 2y term on the left by subtracting 8x from both sides.  We get:

2y = -8x + 14

Dividing both sides by 2 isolates y:

         8x + 14          

y = -----------------  =  4x + 7  

             2

y = 4x + 7

The solution for y will be -4x+7

We were given 8x+2y=14

We then isolate y for easy calculation

2y= -8x+14

We divide both sides by 2

2y = -8x+14

2        2

y= -4x+7

Step-by-step explanation:

Can I please have Brainliest?

There are 480 calories are in the 3-ounce size of the bar.

Multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Green Frog convenience store supplies two types of protein bars.

And, One protein bar has 320 calories in the 2-ounce size.

Now,

For 1 ounce size, calories in One protein bar = 320 / 2

                                                                  = 160

Hence, We get;

For 3 ounce size, calories in One protein bar = 160 x 3

                                                                      = 480

Thus, There are 480 calories are in the 3-ounce size of the bar.

Answer:

-6

Step-by-step explanation:

Answer:

A) zeros are x = ½ or x = ½

B) >> sum of zeros = (-Coefficient of x)/(Coefficient of x²)

>> Product of the zeros = Constant term/Coefficient of x²

Step-by-step explanation:

To find the zeros, we will equate the polynomial to zero.

Thus;

4x² - 4x + 1 = 0

Using quadratic equation, we can find the zeros.

x = [-(-4) ± √((-4)² - (4 × 4 × 1))]/(2 × 4)

x = (4 ± 0)/8

x = 4/8 and x = 4/8

Thus, zeros are x = ½ or x = ½

Now, to find the relationships between its zeroes and coefficients;

Sum of zeroes = ½ + ½ = 1

This is equal to -b/a = -(-4)/4 = 1.

Thus;

sum of zeros = (-Coefficient of x)/(Coefficient of x²)

Product of zeros = ½ × ½ = ¼

c/a = 1/4

This is equal to the product of the zeros.

Thus;

Product of the zeros = Constant term/Coefficient of x²

Measure of angle A = 55°.

Step-by-step explanation:

From the picture attached,

[tex]\frac{AC}{LN}=\frac{BC}{LM}[/tex]

[tex]\frac{10}{5}=\frac{8}{4}[/tex]

2 = 2

Corresponding sides of the given triangles ΔACB and ΔNLM are proportional.

Therefore, ΔACB ~ ΔNLM.

m∠A = 180° - (90° + 35°) [By triangle sum theorem]

         = 180° - 125°

         = 55°

Measure of angle A is 55°.

4x + 8y = -40

if x = -6

4(-6) + 8y = -40

-24 + 8y = -40

8y = -40 + 24

8y = - 16

y = -16/8

y = -2

Answer:

Step-by-step explanation:

To find value of y

4x + 8y = -40

x = -6

=> 4x + 8y = -40

[By putting the value of x = -6 then ]

=> 4×(-6) + 8y = -40

=> -24 + 8y = -40

=> 8y = -40 + 24

=> 8y = -16

[tex] = > y = \frac{ - 16}{8} [/tex]

=> y = -2
