Answer:y=4x+6

Step-by-step explanation:

We have the information that the slope is 4 and the line goes through the point (-2,-2). With this information, we can make a linear equation in a point slope form ( $y - y_{1}= m * (x - x_{1})$ , so the equation would be $y+2=4(x+2)$ , or simplified, $y+2=4x+8.$ in order to solve for y (to make it a slope-intercept equation), we must subtract 2 from both sides. This gives us the equation y=4x+6. Hope this helps!

A customer orders a round of coffee for her friends. If she orders two 12-ounce cups and one 16-ounce cup, she will owe the coff

Answer:

D.$3.95

Step-by-step explanation:

Let us represent

12-ounce cup = x

16-ounce cup = y

A customer orders a round of coffee for her friends.

If she orders two 12-ounce cups and one 16-ounce cup, she will owe the coffee shop $10.75.

Hence:

2x + y = 10.75.....Equation 1

y = 10.75 - 2x

If she orders one 12-ounce cup and two 16-ounce cups, she will owe the coffee shop $11.30.

Hence:

x + 2y = 11.30.....Equation 2

We substitute 10.75 -2x for y in Equation 2

x + 2(10.75 - 2x) = 11.30

x + 21.50 - 4x = 11.30

Collect like terms

x - 4x = 11.30 - 21.50

-3x = -10.20

x = -10.20/-3

x = $3.40

Solving for y

y = 10.75 - 2x

y = 10.75 - 2($3.40)

y = 10.75 - 6.8

y = $3.95

Therefore , 16-ounce cup is represented by y, the cost for a 16-ounce cup of coffee is $3.95

Option D is correct

tangare [24]

Step-by-step explanation:

Range if third side is in between 10-22

Reason:

For the lowest value of third side 16-6= 10

For the highest value if third side 16+6= 22

The product of a number and 12 is nomore than 15

allsm [11]

Answer:

As an equation, the product of a number and 12 is no more than 15 would be:

12n ≤ 15

N would represent the number.

≤ means less than or equal to, which is the same as "no more than".

NEED HELP ASAP!!!!!!!!!!! 2. Solve for x 3. Solve for x

Anton [14]

Answer:

2. x = 47

3. x = 2

Step-by-step explanation:

These problems involve proportions, or equivalent ratios. You can solve for 'x' in each by using cross-multiplication and division.

2. 28(7) = 4(x + 2)

Distribute = 196 = 4x + 8

Subtract 8 from both sides: 196 - 8 = 4x + 8 - 8 or 188 = 4x

Solve for x: x = 47

3. 2(2x + 7) = 11(3x - 4)

Distribute: 4x + 14 = 33x - 44

Add 44 to both sides: 4x + 14 + 44 = 33x - 44 + 44 or 4x + 58 = 33x

Subtract 4x from both sides: 4x + 58 - 4x = 33x - 4x or 58 = 29x

Solve for x: x = 2
