1. You start at (0,-3) because the last number in slope intercept form (the equation above) represents the y intercept.
2. Plot a point at (0,-3).
3. The 3/2 represents the slope, so from (0,-3), go up 3 lines and right 2 lines. Keep plotting the points. You can also go down 3 and left 2.
4. Make a line from the points.

One angle of a triangle is a right angle. The second angle measures 41 degrees. What is the measurement of the third angle? A. 4

BARSIC [14]

Answer:

All triangles add up to 180 degrees

right angles are 90 degrees

we add 41 and 90 to find how many degrees are already there

41 + 90 = 131

we need 180 degrees so we see how many degrees are left

180 - 131 = 49

49 degrees are left so 49 is the answer because 49 finishes the triangle

Hope this helps

Answer:

A pound of potato costs $3.10

A dozen egg costs $5.5

A wheel of cheese costs $6.25

Step-by-step explanation:

Represent

- a dozen egg with D

- a wheel of cheese with W

- a pound of potato with P

For Adam:

$3D + W + 5P = 38.25$ ---- (1)

For Barry:

$D + 10P = 36.50$ ---- (2)

For Charles:

$2D + 2P = 17.20$ ---- (3)

Make D the subject in (2)

$D = 36.50 - 10P$

Substitute 36.50 - 10P for D in (3)

$2(36.50 - 10P) + 2P = 17.20$

$73 - 20P + 2P = 17.20$

$73 - 18P= 17.20$

Collect Like Terms

$- 18P= 17.20 - 73$

$- 18P= -55.8$

$18P= 55.8$

Solve for P

$P = 55.8/18$

$P = 3.1$

Substitute 3.1 for P in $D = 36.50 - 10P$

$D=36.50 - 10 * 3.1$

$D=36.50 - 31$

$D=5.5$

Substitute 3.1 for P and 5.5 for D in $3D + W + 5P = 38.25$

$3(5.5) + W + 5(3.1) = 38.25$

$16.5 + W + 15.5 = 38.25$

Solve for W

$W = 38.25 - 16.5 - 15.5$

$W = 6.25$

You take out the negative and do the regular equation but turn it into the fraction with one as the numerator and the solution of the exponent as the denominator.
