Mathematics

vagabundo [1.1K]3 years ago
6 0

Answer:

To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.

- x + 2 = - 1 + 2 = 1

Now - 3 < 1

Thus (1, - 3) is not a solution

Find the perimeter of a rectangle whose length is 150 m and the diagonal is 170 m
zzz [600]

Answer:

460 m

Step-by-step explanation:

Use right triangle PSR with right angle S to find the length of PS.

The Pythagorean theorem can be used for this.

a^2 + b^2 = c^2

(PS)^2 + (SR)^2 = (PR)^2

(PS)^2 + (150 m)^2 = (170 m)^2

(PS)^2 = 22500 m^2 = 28900 m^2

(PS)^2 = 6400 m^2

PS = 80 m

PS = 80 m; SR = 150 m

perimeter = 2(length + width)

perimeter = 2(150 m + 80 m)

perimeter = 2(230 m)

perimeter = 460 m

Put this equation into slope-<br> intercept form.<br> 3x – 2y = 4
PtichkaEL [24]

Answer:

y= 3/2x -2

Step-by-step explanation:

make y be on one side by itself ( -2y = -3x + 4 )

divide by negative 2 in order to get y by itself ( -2y/-2 = -3/-2 + 4/-2 )

two negatives make a positive ( y = 3/2 + -2 )
