3 Markers Cost $5.79. Which Equation Would Help Determine The Cost Of 13 Markers?

2 answers:

6 0

If we know the cost of 3 markers, we need the unit price to set up an equation for 13 since 13 does not divide by 3 nicely.

$5.79 ÷ 3 = $1.93 for each marker.

If m = marker
1.93m will provide the cost of any number of markers.

First you would find out how much one cost

you do 5.79 / 3= 1.93

then mutliply= 1.93 x 12= $25.09

$25.09 is your answer

Write the slope-intercept form of the equation of the line; (-5,-4) and prep. To y equals 5x plus 1

ohaa [14]

Answer:

$y=-\frac{1}{5} x-5$

Step-by-step explanation:

The given line is defined by: $y=5x+1$ , where we see that the slope is 5 and the y-intercept 1.

In order to find a line perpendicular to the given one, we need it to have a slope that is the "opposite of the reciprocal" of the given slope.

"Opposite" means it would have its sign inverted (in our case from positive to negative); and "reciprocal means that instead of 5, it would be its reciprocal: $\frac{1}{5}$ .

We can write this new line with such slope, and try to find its y-intercept (b) by using the given condition that requires it to go through the point (-5,-4) on he plane:

$y=-\frac{1}{5} x+b$

we require then that when $x=-5$ , the value of $y=-4$ .

Therefore: $-4=-\frac{1}{5} (-5)+b\\-4=\frac{5}{5} +b\\-4=1+b\\b=-4-1=-5$

Then our final answer is that the new line should have the form: $y=-\frac{1}{5} x-5$

Evaluate: <img src="https://tex.z-dn.net/?f=%5Csqrt%5B-3%5D%7B27%7D" id="TexFormula1" title="\sqrt[-3]{27}" alt="\sqrt[-3]{27}"

GenaCL600 [577]

Answer:

1/3 is the simplified form for given expression.

Step-by-step explanation:

Given that:

= $\sqrt[-3]{27}$

By simplifying:

Radical sign will be removed as follows:

= $27^{-1/3}$

For removing the "-" sign from power, base will be inverted:

= $(1/27) ^ {1/3}$

27 can also be written as 3 * 3 * 3 = 3^3

So,

= $(1/3^3)^{1/3}$

= $1^{1/3} / 3^{3* 1/3}$

By simplifying we get:

= 1/3

i hope it will help you!

1. Which range of numbers is most appropriate for the y-axis scale and interval on a graph given the

nata0808 [166]

Answer:

Option B.

Step-by-step explanation:

We need to find the range of numbers is most appropriate for the y-axis scale and interval on a graph for given table.

From the given table it is clear that the minimum value of y is 10 and the maximum value of y is 34.

It means 10 and 34 must be included in the Range.

In option C and D 34 in not included in the range, so these options are incorrect.

In option A, 10 is the minimum value of range and interval of 10 is not possible for the range 10-35, because it contains only multiple of 10 on the y-axis. So, this option is incorrect.

In option B, both 10 and 34 are included and interval of 5 is possible for range 0-35.

Therefore, the correct option is B.

Find the midpoint between 7, -2 and -4,2

SpyIntel [72]

Answer:

The midpoint is (3/2,0)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinate of the endpoints and divide by 2

(7+-4)/2 = 3/2

To find the y coordinate of the midpoint, add the y coordinate of the endpoints and divide by 2

(-2+2)/2 = 0

The midpoint is (3/2,0)
