Explain how showing fractions with a model and a number line are alike and different

You use a number line to see what is greater and less than. And use a model to visualize it more. And they are alike because they can both help in the same way but for different people.

Find the x and y intercept of y= -2(x-3)^2+4

Neko [114]

Y intercept occurs when x = o so it is -2(0-3) + 4 = -2

x intercepts:-

-2(x - 3)^2 + 4 = 0

(x - 3)^2 = -4/-2 = 2

x - 3 = +/- sqrt2

x = 3 + sqrt2 and 3- sqrt2

What is the simplest form of the product cube root4x^2*cube root8x^7

Illusion [34]

Answer:

f(x) = $2^{\frac{5}{3} }x^{3}$ is the simplest expression

Step-by-step explanation:

We are given an expression and we are supposed to find the simplest form of the given expression.

The given expression is

f(x) = $\sqrt[3]{4x^{2} } \times \sqrt[3]{8x^{7} }$

Since the cube root is common we can multiply the quotient inside the radical sign.

f(x) = $\sqrt[3]{32x^{(2+7)} }$

= $\sqrt[3]{32x^{9} }$

= $2^{\frac{5}{3} }\times x^{\frac{9}{3} }$

= $2^{\frac{5}{3} }x^{3}$

f(x) = $2^{\frac{5}{3} }x^{3}$ is the simplest expression

Find the value of each variable. Write the<br> equation and solve showing ALL the work.

Wittaler [7]

Answer:

x = 96°

y = 102°

Step-by-step explanation:

Angles on a straight line add up to 180

78 + y = 180

y = 180 - 78

y = 102

Angles in a quadrilateral add up to 360

78 + 90 + x + x = 360

78 + 90 + 2x = 360

168 + 2x = 360

2x = 360 - 168

2x = 192

x = 192/2

x = 96°
