you must substitute x in the equation given :)

examples:

when x is -2

therefore, y = 2(-2) + 3

y = -1

when x is 0

therefore, y = 2(0) + 3

y = 3

when x is 1

therefore, y = 2(1) + 3

y = 5

when x is 3

therefore, y = 2(3) + 3

y = 9

for (b) you only have to plot based on the table ;)

hope this helps

A website sells a dress at £40 and shoes at £32. The website has an offer: Buy a dress and shoes together and get 1/2 off the pr

tekilochka [14]

Answer:

$\pounds36$

Step-by-step explanation:

Cost of one dress = $\pounds40$

Cost of one pair of shoes = $\pounds32$

Cost of one dress and a pair of shoes is $40+32=\pounds72$

They get half off the price because they buy both

$\dfrac{72}{2}=\pounds32$

The shipping and handling charge is $\pounds4$ .

So, the total amount Ruth has to pay is $32+4=\pounds36$ .

Which expression converts startfraction pi over 4 endfraction radians to degrees?

scZoUnD [109]

Using the degree and radian relation π/4 radian equals 45°.

Given angle =π/4 radian

<h3>What is the relation between radian and a degree?</h3>

π radian equals 180 degrees means 1 radian equals 180/π degree or we can say 1-degree equals π/180 radian.

Since, 1 radian equals 180/π degree.

So, π/4 radian =180/π * π/4 degree.

π/4 radian = 45°.

So, π/4 radian equals 45°.

Therefore, using the degree and radian relation π/4 radian equals 45°.

△ABC has interior angles with measures x°, 100°, and 70°, and △DEF has interior angles with measures y°, 70°, and 20°. Using the

Umnica [9.8K]

△ABC has interior angles with measures x°, 100°, and 70°.

By using angle sum property, which states that the sum of measures of all three angles is 180 degrees.

$x^{\circ}+100^{\circ}+70^{\circ}=180^{\circ}$

$x^{\circ}=10^{\circ}$

Now, △DEF has interior angles with measures y°, 70°, and 20°.

By using angle sum property,

$y^{\circ}+70^{\circ}+20^{\circ}=180^{\circ}$

$y^{\circ}=90^{\circ}$

Now, we can say that,

"The two triangles are not similar because x≠y"

As one angle of measure 70 degree is common in both the triangles.

If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.

Therefore, the two triangles are not similar because x is not equal to y.

Vanyuwa [196]

21 + 20 = 43

Total is 123, so divide by 43.

123/43 = 2.86 rounded to 3.
