2A + B = 17

3A - B = 18

5A = 35, A = 7, B = 3

Point A is at (-5, -4) and point M is at (0, -3.5).
ludmilkaskok [199]

Answer:

The coordinates of point B are (5,-3)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

In this problem

Point A is at (-5, -4) and point M is at (0, -3.5)

point\ A=(x_1,y_1)\\point\ B=(x_2,y_2)\\point\ M=(0,-3.5)

substitute in the formula

(0,-3.5)=(\frac{-5+x_2}{2},\frac{-4+y_2}{2})

so

Solve for x_2

0=\frac{-5+x2}{2}\\x_2=5

Solve for y_2

-3.5=\frac{-4+y_2}{2}\\-7=-4+y_2\\y_2=-3

therefore

The coordinates of point B are (5,-3)

What is the y-intercept and x-intercept for the equation -3x - 4 = -5y - 8
BARSIC [14]

Step-by-step explanation:

=> -3x - 4 = -5y - 8

=> 8 - 4 = 3x - 5y

=> 4 = 3x + (-5)y

=> 1 = (3x/4) + (-5y/4)

=> 1 = x/(4/3) + y/(-4/5)

Compare this with x/a + y/b = 1 where a and b are x & y intercepts.

Here,

x intercept = 4/3

y intercept = -4/5

When a hockey team gets possession of the puck, the following probabilities have been
Natasha_Volkova [10]

Answer: p(a given b) = p(a and b) / p(b)

a is the probability that they score.

b is the probability that they cross the blue line.

p(a and b) is given as .005

this is the probability that they cross the blue line and score.

p(b is given as .6

that's the probability that they cross the opposing blue line.

the formula becomes:

p(a given b) = .005 / .6 = .0083333333.....

that's what i get using the p(a given b) formula.

Sara paid $11.88 total for apples, after a 3 dollar coupon, and $7.58 for berries with a $20 bill. How much change did Sara rece
Nataliya [291]

After the discount, Sara received a change of <u>$3.54</u>.

Define discount.

The discount is <u>determined by dividing the purchase price by the item's par value</u>. Discount is the type of original price reduction or a new lower price for a product. In other words, a discount i<u>s a sum of money or a portion of the regular selling price of anything</u>.

Given that a discount is the price reduction of goods or services that store owners give at the advertised price, it can be computed using the formula <u>Discount = List Price - Selling Price.</u>

Solution Explained:

Given,
Price of apples = $11.88, price of berries = $7.58

The discount on the coupon is $3 and she paid with a $20 bill

So, total cost = 11.88 + 7.58 = 19.46

Applying discount on the cost =  19.46 - 3 = 16.46

The total change Sara gets is = 20 - 16.46 = $3.54

Therefore, Sara receives a change of $3.54
