Answer:

35 deg

Step-by-step explanation:

since ABC is straight line. angle ABC should be 180 deg. implies

$45 + 100 + x = 180 \\ x = 180 - 100 - 45 \\ x = 35 \: degree$

In need of some help! Thank you in advance. 100 points <3

Answer:

the equation (x-4)^2-17=8 has two solutions because it is in a quadratic form.

(x-4)^2-17=8

x²-8x+16-17-8=0

x²-8x-9=0

Doing middle term factorization

x²-9x+x-9=0

x(x-9)+1(x-9)=0

(x-9)(x+1)=0

either

x=9

x=9or

x=9orx=-1

x^2+4x+3=0:

Doing middle term factorization

x²+3x+x+3=0

x(x+3)+1(x+3)=0

(x+3)(x+1)=0

either

x=-3

x=-1

Josh’s solution is incorrect because he missed x=-3.

3.

x^2-6x+7=0

By using quadratic equation formula:

Comparing above equation with ax²+bx+c=0

we get

a=1

b=-6

c=7

Now

we have

x= $\frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a}$

x= $\frac{ 6± \sqrt{ {-6}^{2} - 4*1*7} }{2}$

x= $\frac{ 6±2\sqrt{ 2}}{2}$

x= ${ 3±\sqrt{ 2}}$

Taking positive

x= ${ 3+\sqrt{ 2}}$

taking negative

x= ${ 3-\sqrt{ 2}}$

If h(x) = −5x − 10, find h(−2). −20 1.6 −1 0

LiRa [457]

H(x) = -5x - 10
h(-2) = -5(-2) - 10
h(-2) = 10 - 10
h(-2) = 0

The solution is 0.
