What is the solution to the system of equations2x + 3y = 40andy=x + 10?
A
x = 2; y = 12
B
x = 4; y = 14
C x = 12; y = 2
D x = 14; y = 4

Answers

Answer 1

Answer:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

Hope that helps

A line includes the points (-1,0) and (-2,-9). What is its equation in slope-intercept form?​

Answers

Answer:

y = -7x -7

Step-by-step explanation:

If (-1, 0) and (-2, -9) are on the same line then that means their slope is the same. We can find slope with (y1 - y2)/(x1 - x2)

(-2 - (-9)) / (-1 - 0) = 7 / -1 = -7

then we can use the formula y = mx + b

we know that forthe first instance y = 0 and x = -1 and m(slope) = -7

0 = -7*-1 + b

0 = 7 + b

b = -7

our formula then becomes y = -7x -7

inequality to represent this situation.

Answers

y-step explanation:

Answer:

10o + 15g ≥ 500

Step-by-step explanation:

Variables:

O = oranges

G = grapefruit

10 boxes of oranges (10o) and 15 boxes of grapefruit (15g) are being added together (10o + 15g). The band wants to raise AT LEAST (greater than or equal to ≥) $500.00.

Put that together, and it's:

10o + 15g ≥ 500

Cans of tuna cost $3.00 for 6 ½ ounces. At that rate, how much would 104 ounces of tuna cost?

HELP FOR POSSIBLE BRAINLIEST!

Answers

Answer:

$48.00

Step-by-step explanation:

$3.00 / 6.5 oz = [unknown $] / 104 oz

unknown $ = 104 oz * $3.00 / 6.5 oz

unknown $ = 16 * $3.00 ((oz/oz cancels out))

unknown $ = $48.00

Answer:$48

6 1/2 = 6.5

Step-by-step explanation:

If $3.00 for 6.5 (6 1/2) ounces

(3 x 2 = 6) Then $6.00 is for 13 ounces

(3 x 10 = 30) then $30.00 is for 65 ounces

(3 x 15 = 45) then $45.00 is 97.5 ounces

(3 x 16 = 48) then $48.00 is 104 ounces.

If you multiply the dollars you will also have to multiply the ounces with the same number you multiplied with dollars.
