60-56=4 kg

2) 9 rows

6*12=72

72/8=9

3) 49 chairs

14*16=224

224-175=49

4) 40

125-45=80

80/2=40

5) 60 years old

10*2=20

20*3=60

6)

3*5.50=$16.50

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

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

$x=3$

On a piece of paper, graph f(x)=16x0.5^x. Then determine which answer choice matches the graph you drew.

Reil [10]

9514 1404 393

Answer:

Step-by-step explanation:

You can use x=0 and x=1 to find points that must be on the graph.

f(0) = 16·0.5^0 = 16

f(1) = 16·0.5^1 = 8

Only graph A matches these points.
