Answer:

x=-2 ⇒ y=2

x=-1 ⇒ y=-4

x=0 ⇒ y=-6

x=1 ⇒ y=-4

Step-by-step explanation:

Formula: y=2x^{2} -6

To find the value of y add the value of x given:

Now solve for each:-

For:

x=-2

y=2(-2)^{2} -6

y=2

For:

x=-1

y=2(-1)^{2} -6

y=-4

For:

x=0

y=2(0)^{2} -6

y=-6

For:

x=1

y=2(1)^{2}-6

y=-4

Answer:

x = 40

smaller angle is 80

larger angle is 100

Step-by-step explanation:

Supplementary angles add up to equal 180 degrees

Hence, x + 40 + 3x - 20 = 180

( note that we just created an equation that we can use to solve for x )

We now solve for x using the equation created

x + 40 + 3x - 20 = 180

step 1 combine like terms

x + 3x = 4x

40 - 20 = 20

we now have 4x + 20 = 180

step 2 subtract 20 from each side

180 - 20 = 160

we now have 160 = 4x

step 3 divide each side by 4

160 / 4 = 40

4x / 4 = x

we're left with x = 40

we now plug in 40 for x to find the value of each angle

x + 40

* substitute 40 for x *

40 + 40 = 80

3x - 20

* substitute 40 for x *

3 ( 40 ) - 20

3 * 40 = 120

120 - 20 = 20

so the larger angle is 100 degrees and the smaller angle is 80 degrees

irinina [24]

Answer:

Subtract 4 and then add 6.

Step-by-step explanation:

8-4=4

4+6=10

10-4=6

6+6=12

12-4=8

8+6=14

The rule for this pattern can be subtracting 4, and then adding 6.

ΔABC and ΔXYZ are similar triangles. If BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4, find the value of x.
Nat2105 [25]

Solution:

we are given that ΔABC and ΔXYZ are similar triangles.

As we know , when two triangles are similar then the ratios of their corrsponding sides are equal.

Here we have

BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4

So we can write

\frac{x+9}{x+5}= \frac{x+7}{x+4}\\&#10;\\&#10;(x+9)(x+4)=(x+7)(x+5)\\&#10;\\&#10;x^2+13x+36=x^2+12x+35\\&#10;\\&#10;13x-12x=35-36\\&#10;\\&#10;x=-1\\&#10;\\

Hence then value of x=-1.
