Answer:

C) Linear

Step-by-step explanation:

We can see from the plot that the data approach a straight line.

This means we can draw a line of best fit through this data and it should hit several data points; thus the answer is linear.

This is a goofy question. The data would be well modeled by a linear function which includes a constant offset (y intercept). But a quadratic will actually fit the given data a bit better because there's an extra parameter in the model so more opportunity to capture variance.

I can't see the other choices but I'll guess they want us to answer Linear even though I think it's wrong.

Assume that the wooden triangle shown is a right triangle.

a.

a^2 + b^2 = c^2

The legs are a and b. c is the hypotenuse.

Let a = 6x + 9y; b = 8x + 12y; c = 10x + 15y

The equation is:

(6x + 9y)^2 + (8x + 12y)^2 = (10x + 15y)^2

b.

Now we square each binomial and combine like terms on each side.

36x^2 + 108xy + 81y^2 + 64x^2 + 192 xy + 144y = 100x^2 + 300xy + 225y^2

36x^2 + 64x^2 + 108xy + 192xy + 81y^2 + 144y^2 = 100x^2 + 300xy + 225y^2

100x^2 + 300xy + 225y^2 = 100x^2 + 300xy + 225y^2

The two sides are equal, so it is an identity.

Graph the inequality x plus y is equal to or greater than -4
Setler [38]

Answer:

Step-by-step explanation:

x+y≥-4

consider x+y=-4

when x=0,y=-4

point is (0,-4)

when y=0,x=-4

point is (-4,0)

draw a line through (0,-4) and (-4,0)

put x=0,y=0

0+0≥-4

which is true.

Hence origin lies on the graph.

graph is on and right of the line.

Write the ratio 4/7 over 1/8 in simplest form. How is the simplest form of the ratio 4/7 over 1/8 related to the simplest form o
PIT_PIT [208]

Answer:

Step-by-step explanation:

Ratio = 4/7 : 1/8

        =\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}

       = 32 : 7

\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}

= 7 : 32

Ratio 4/7 over 1/8  is the multiplicative inverse of the ratio 1/8 over 4/7
