What numbers match the equations

1 answer:

6 0

Y = 2/3x + 5....slope here is 2/3...so the line is increasing...going up....the 5 in the equation is ur y int, where the line crosses the y axis....so this equation will be line 4

y = x - 3....slope is 1....increasing....y int is -3....this is line 1

y = -3/4x + 3....slope is -3/4.....this one is decreasing...going down...the y int is 3....so this is line 2

y = -1/2x - 4....slope is -1/2...so this is decreasing...y int is -4...so this one is going to be line 3

Answer:

4 * (-2)^2 - (6+(-9))

= 4 * 4 - (-3)

= 16 - (-3)

= 16 + 3

Error Analysis: A student solves the equation S=2Lw+2Lh+2Wh for W and his answer are W=S-2Lh-2Lh\h Describing and correct the st

serious [3.7K]

S=2LW+2LH+2WH

First, subtract 2LH from both sides
S-2LH=2LW+2LH-2LH+2WH
S-2LH=2LW+2WH

Separate out the W
S-2LH=W(2L+2H)

Divide by 2L+2H to get W alone

$\frac{S-2LH}{2L+2H} =W$

Hope this helps.

Help i tried and cant get the answer lol

zloy xaker [14]

Answer:

$209 \frac{3}{4} - {3}^{2} \times (8 {}^{2} - 38 \frac{1}{2} ) \\ = 209 \frac{3}{4} - 3 {}^{2} \times 25 \frac{1}{2} \\ = 209 \frac{3}{4} - 229 \frac{1}{2} \\ = - 19 \frac{3}{4}$

In a parallelogram, opposite sides are parallel and equal . So to prove JKLM a parallelogram, we need to satisfy both criterias . And only the last option stand up on both criterias that is opposite sides are parallel and equal .

So the correct option is the last option .
