Answer:

y = 8

x = 21

Step-by-step explanation:

Find x first. Since there is a straight line, we can conclude it's equal to 180 degrees.

11x + 10 -61 = 180

Add 10 to negative 61.

11x - 51 = 180

Add 51 to both sides.

11x = 231

Divide 11 both sides

x = 21.

Now put x in the equations to solve.

This is for the small angle on the right side.

(21+10) = 31

This is for the big angle on the right side.

(10(21) - 61)

210 - 61 = 149.

Now for the other side, we know the degree for the smaller side on the left side since it's a vertical angle.

31 degrees for top left angle. Since we know this side is 180 just subtract 31 from 180 and you'll get 149.

18y + 5 = 149

Subtract 5 both sides.

18y = 144

y = 8.

We observe that a line will pass through 3 points, but to find a slope we only need two.

We see that it passes through points (assuming the scale of graph is 1 : 1) P_1(x_1,y_1)=P_1(0,1) and P_2(x_2,y_2)=P_2(2,-1).

We can use slope formula that applies for any line and produce the same slope for any two different points on the line

m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-1}{2-0}=-1

So the slope is -1 also it intersects y-axis at n=1 so the general form of the linear function is

f(x)=mx+n

That is in your case

\boxed{f(x)=-x+1}

Hope this helps.

Find the area of the composite figure.
REY [17]
Answer: 174ft^2


Area of triangle: (bh)/2

A = (6*4)/2
A = 24/2
A = 12ft^2


Area of rectangle: LW

A = 18(9)
A = 162ft^2

Add area of rectangle and triangle together


A = 162ft^2 + 12ft^2
A= 174ft^2

A teacher bought 7 packs of dominoes for a math game. Each pack had 55 dominoes. The teacher already had 118 dominoes to use in
Mamont248 [21]

Answer:

the teacher had 503 dominoes for the game.

Step-by-step explanation:

In order to find the answer, first you have to find the amount of dominoes the teacher purchased by multiplying the number of packs for the number of dominoes in each pack:

7*55=385

Now, since the stament indicates that the teacher already had 118 dominoes to use in the game, you have to add this amount to the number of dominoes that were purchased:

385+118=503

According to this, the answer is that the teacher had 503 dominoes for the game.

Find function then simplify tje answer
Scrat [10]

Answer:

a)(x+h+2)²=x²+2xh+h²+4x+4h+2

b)(x+h+2)²–(x+2)²=2xh+h²+4h

c)2x+4+h

Step-by-step explanation:

f(x)=x²+4x+2

Aight so for part a you have to replace x with x+h

a)f(x+h)=(x+h)²+4(x+h)+2=x²+2xh+h²+4x+4h+2

and then for part b you need to subtract f(x) from part a:

b)f(x+h)–f(x)=x²+2xh+h²+4x+4h+2–x²–4x–2===>

2xh+h²+4h

and for part c divide the answer by h:

c)

\frac{f(x + h) - f(x)}{h}  =  =  =  > \\  \frac{2xh + 4h +  {h}^{2} }{h}  =  =  =  >  \\ 2x + 4 + h

and if you limit h by 0 you'll get the derivative of f(x)
