449-162=287

Therefore, since it's 5 or above, this case it's a 7, you'll round it up. Since it's to the nearest hundredth, it is 300.

67a(t+z)=45z+67 solve for (z)

lora16 [44]

Answer: z = $\frac{67(1 - at)}{67a - 45}$

Step-by-step explanation:

67a(t + z) = 45z + 67

67at + 67az = 45z + 67

-67at -45z -45z -67at

67az - 45z = 67 - 67at

z(67a - 45) = 67 - 67at

÷ (67a - 45) ÷ (67a - 45)

z = $\frac{67 - 67at}{67a - 45}$

= $\frac{67(1 - at)}{67a - 45}$

Solve x2 - 8x + 14 = 2x - 7

BabaBlast [244]

Answer:

x=7, x=3

Step-by-step explanation:

$x^{2} -8x+14=2x-7$

$x^{2} -8x-2x+14+7=0$

$x^{2} -10x+21=0$

$\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}$

$x=$ $\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

positive

$x=\frac{-\left(-10\right)+\sqrt{\left(-10\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}$

$x=7$

negative

$x=\frac{-\left(-10\right)-\sqrt{\left(-10\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}$

$x=3$

The point slope of a line that has a slope of -2 and passes through point (5,-2) is shown below. Which equation is in slope inte

kramer

Y + 2 = -2(x - 5)

Simplify.

y + 2 = -2x + 10

Subtract 2 from both sides.

y = -2x + 10 - 2

Simplify.

y = -2x + 8 → Slope-intercept form

Our answer is the second option : y=-2x+8

~Hope I helped!~
