Find the values of x and y that make k ll j and m ll n

Mathematics
1 answer:
777dan777 [17]3 years ago
3 0

Answer:

<u><em>x = 80</em></u>

<u><em>y = 130</em></u>

Step-by-step explanation:

The 2 angles are supplementary. so, x-30 + x+50 = 180.

We solve and get 2x = 180-20

<u><em>x = 80</em></u>

y = x+50, because of parallel rules.

<u><em>y = 130</em></u>

san4es73 [151]

Answer:

5, 29 will both blank boxes

Step-by-step explanation:

the product of (4z^2 + 7z – 8) and (–z + 3)

(4z² + 7z – 8)(–z + 3)

-z(4z² + 7z – 8) + 3(4z² + 7z – 8)

-4z³-7z²+8z+12z²+21z-24

choose like terms

-4z³-7z²+12z²+8z+21z-24

-4z³+5z²+29z-24

HELP WANTED, APPRECIATED, AND NEEDED ASAP
Anit [1.1K]

Let's assume

x is number of hours worked

y is amount paid

Since, this is linear relationship

We can select any two points

(2,36.50) and (4,73)

so, we can also write as

x1=2 , y1 =36.50

x2=4 , y2=73

Firstly, we can find slope

m=\frac{y_2-y_1}{x_2-x_1}

we can plug values

m=\frac{73-36.50}{4-2}

m=18.25

now, we can use point slope form of line

y-y_1=m(x-x_1)

we can plug values

y-36.50=18.25(x-2)

now, we can solve  for y

y=18.25x

or

y=18.3x..............Answer
