Answer:

x = \frac{1}{2} , y = 3

Step-by-step explanation:

y = 2x + 2 → (1)

y = - 2x + 4 → (2)

Substitute y = 2x + 2 into (2)

2x + 2 = - 2x + 4 ( add 2x to both sides )

4x + 2 = 4 ( subtract 2 from both sides )

4x = 2 ( divide both sides by 4 )

x = \frac{2}{4} = \frac{1}{2}

Substitute this value into (1) for value of y

y = 2(\frac{1}{2} ) + 2 = 1 + 2 = 3

Ymorist [56]

Answer:

Step-by-step explanation:BASE+3X=22.85

BASE+10X=40

BASE=40-10X NOW SUBSTITUTE (40-10X)FOR BASE IN THE FIRST EQUATION

40-10X+3X=22.85

-7X=22.85-40

-7X=-17.15

X=-17.15/-7

X=$2.45 IS THE PRICE FOR EACH POUND.

BASE+10*2.45=40

BASE+24.50=40

BASE=40-24.50

BASE=15.50 IS THE BASE PRICE FOR THE DELIVERY.

PROOF

15.50+3*2.45=22.85

15.50+7.35=22.85

22.85=22.85

All you need is in the photo ​<br><br><br>please explain step by step
V125BC [204]

Answer:

Hi there

The formula is

A=p (1+r)^t

A future value

P present value

R interest rate

T time

A) A=2,000×(1+0.04)^(3)=2,249.728

B) A=2,000×(1+0.04)^(18)=4,051.63

C) 2500=2000 (1+0.04)^t

Solve for t

T=log(2,500÷2,000)÷log(1+0.04)

T=5.7 years

D) t=log(3,000÷2,000)÷log(1+0.04)

t=10.3 years

Hope it helps

Y2-y1 and y=me+b<br> Plzz help me with this
mestny [16]
Well if you have the coordinates (2,2) and (4,4) you plug in the y from the second cords for y2

So it would be 4-2/4-2 and 2/2 equals 1
1 would be the m in y=MX+b
Then plug one set of coords in y=MX+b
2=1x+b

I know it's confusing to understand but I tried lol
