Step-by-step explanation:

Answer:

y-intercept(s):  (0,13) max

Step-by-step explanation:

Answer:

Slope is just what is y/x so y=4-3=1, X=3-(-2)=5, remember if you use point 1's y to minus point 2, for x you also need to use point 1's x to minus point 2's x. So it's 1/5

Answer:

Step-by-step explanation:

2) (0,3) ; (3, 2)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

          [tex]=\frac{2-3}{3-0}\\\\=\frac{-1}{3}[/tex]

3)(-2, 1) (3,4)

Slope = [tex]\frac{4 -1}{3-[-2]}[/tex]

          [tex]=\frac{4-1}{3+2}\\\\=\frac{3}{5}[/tex]

Ok sooooooooooo

Lets say your two fractions are

13/26 and 20/40

you can divide the bottom number by the top one and if you get the same answer for both then they are equivalent. For these you get 2 for both, which means they are equivalent.

another example would be if your fractions are

2/5 and 4/10

You can say well 2*2 equals 4 And 5*2 equals ten so these are equivalent fractions.

Answer:

B, 0.07c

Step-by-step explanation:

to get the total sales tax, you need to multiply the price by the tax percent in decimal.

7%=0.07

c= the price

total price =0.07c

Answer:

The first one is a function. The other two are not functions.

Step-by-step explanation:

To find this, you use the vertical line test. If the vertical line touches multiple points on the graphed line, it is not a function. If the vertical line only touches the graphed line at one point, it is a function.

Good Luck! I hope this helps!

Answer:

The answer is D

Step-by-step explanation:

A table of values for a linear function shows a constant rate of change between the x and y values.

Answer:

Yes, it is linear. y=-1/2x+3/4

Step-by-step explanation:

To put it in standard form, you need to get the y by itself.

4y=-2x+3

Divide by 4.

y=-1/2x+3/4

Angle-Side-Angle. The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

Answer:

92

Step-by-step explanation:

To estimate the difference between the standard atomic weights of these two metals we round up the given weights to the nearest whole number

The standard atomic weight for aluminum is 26.98.

To the nearest the whole number = 27

The standard atomic weight for tin is 118.71

To the nearest whole number = 119

Hence,

The estimated difference = 119 - 27

= 92

Answer:

$0.81

Step-by-step explanation:

2.45/3

each were $0.81

Answer:

0.82

Step-by-step explanation:

2.45 divided by 3 is 0.8166666666 so it rounded would be 0.82

Answer:

B, D, and E.

B: As x approaches negative infinity, g(x) approaches positive infinity.

D: As x approaches positive infinity, g(x) approaches positive infinity.

E: Function g is continuous.

Step-by-step explanation:

To answer this question, we will graph it. Please refer to the graph below.

Let’s go through each of the answer choices.

A) Function g is increasing over the entire domain.

Looking at the graph, we can see that this is not true.

More specifically, the red curve is decreasing over its entire interval.

So, A is not correct.

B) As x approaches negative infinity, g(x) approaches positive infinity.

This is true. As x approaches negative infinity i.e. as we go towards the left of the graph, we can see that our function g(x) (the red curve) is approaching positive infinity.

C) Function g includes an exponential piece and a quadratic piece.

This is false. The first piece is indeed exponential, but the second piece is a cubic, not a quadratic.

D) As x approaches positive infinity, g(x) approaches positive infinity.

Again, this is true. As x approaches positive infinity i.e. As we go towards the right of the graph, we can see that our function g(x) (the blue curve this time) is approaching positive infinity.

E) The function is continuous.

For a function to be continuous, it must have no breaks, jumps, and/or gaps.

We can see that our function does not possess any of the above.

So, g(x) is continuous.

Therefore, the correct statements are B, D, and E.

Answer:

Non-proportional

y = [tex]\frac{2}{15}x+20[/tex]

Step-by-step explanation:

If a line doesn't pass through the origin relationship represented by the line is non proportional.

In other words, any line having y-intercept is non-proportional.

From the graph attached,

Line has a y-intercept = 20

Therefore, relationship is non-proportional.

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Since, the given line is passing through (0, 20) and (60, 28),

Slope of the line 'm' = [tex]\frac{28-20}{60-0}[/tex]

m = [tex]\frac{8}{60}[/tex]

   = [tex]\frac{2}{15}[/tex]

y-intercept 'b' = 20

Slope-intercept form of the equation is,

y = mx + b

So the equation will be,

y = [tex]\frac{2}{15}x+20[/tex]

Answer:

1

Step-by-step explanation:

the line crosses the y-axis at the point (0, 1), which is a y-intercept because x=0, so the y-intercept would be 1
