Answer:

(-18, 0).

(-14, 1).

(-22, -1).

Step-by-step explanation:

x - 4y = -18

x = -18 + 4y

Let y = 0, then x = -18 so one point is (-18, 0).

Let y = 1 then x = -18+4 = -14 so another point is (-14, 1).

Let y = -1 then x = -18 +4(-1) = -18 - 4 = -22 so another point is (-22, -1).

a car decreased in value from $980 to $720 in one year what was the per cent of decrease to the nearest whole per cent ?

kolezko [41]

The decrease was 27%.

Step-by-step explanation:

Old value = $980

New value = $720

Decrease = Old value - New value

$Decrease=980-720=\$260$

Percent decrease = $\frac{Decreased/ amount}{Old value}*100$

$Percent\ decrease=\frac{260}{980}*100\\Percent\ decrease=0.265*100\\Percent\ decrease= 26.5\%$

Rounding off to near whole percent

Percent decrease = 27%

The decrease was 27%.

Please help me solve this

Nataly_w [17]

Answer:

x = 24

Step-by-step explanation:

using the rule of exponents

$a^{m}$ × $a^{n}$ = $a^{(m +n)}$

consider left side

$5^{\frac{x}{6} }$ × $5^{\frac{x}{2} }$

= $5^{\frac{x}{6} }$ × $5^{\frac{3x}{6} }$

= $5^{\frac{4x}{6} }$

then

$5^{\frac{4x}{6} }$ = $5^{16}$

since the bases on both sides are equal, both 5 then equate exponents

$\frac{4x}{6}$ = 16 ( multiply both sides by 6 )

4x = 96 ( divide both sides by 4 )

x = 24

Step-by-step explanation:

<u>Initial value is the y-intercept:</u>

b = 1200

<u>Rate of change is the difference in the charge amount per year:</u>

m = (1350 - 1200) / (8 - 5) = 150 / 3 = 50

<u>The equation would be:</u>

y = 50x + 1200
