70 x 2 = 140, so 1 pound 40p. Adding 35p (half of 70p) equals 175p. This is £1.75p.

can anyone please help me I am struggling?? It’s 9th grade algebra 1 average rate of change comparison
gtnhenbr [62]

Answer:

a) 2 b) 1 c) 7/6

Function a(x) = 2x + 3 has the greatest rate of change

Step-by-step explanation:

a(x) = 2x + 3

2(-1) + 3 = 1 (-1,1)

2(2) + 3 = 7 (2,7)

\frac{7-1}{2-(-1)} = 6/3

=2

b(x) = x^2 - 1

(-1)^2 - 1 = 0 (-1, 0)

(2)^2 - 1 = 3 (2,3)

\frac{3-0}{2-(-1)} = 3/3

=1

c(x) = 2^x + 1

2^(-1) + 1 = 1.5 (-1, 1.5)

2^(2) + 1 = 5 (2,5)

\frac{5-1.5}{2-(-1)} = 3.5/3 or 7/6

=7/6

Which of the following equations is of a parabola with a vertex at (0, -5)
Harlamova29_29 [7]

The x, which is zero in this case will always be the number that goes on the inside of the equation, so far you have y=(x+0)^2 or y=x^2.

The y, which is negative will go on the end of the equation. So you get y=x^2-5

The equation is y=x^2-5 or C if it is multiple choice

Find the midpoint of points A(8,-7) and B(3,-1) graphically
sukhopar [10]

Answer: (5.5, -4)

Step-by-step explanation:

You can use the midpoint formula to find the midpoint of point A and point B.

M(\frac{x_{1}+x_{2} }{2}, \frac{y_{1} + y_{2} }{2})

x₁ = 8

x₂ = 3

y₁ = -7

y₂ = -1

M(\frac{x_{1}+x_{2} }{2}, \frac{y_{1} + y_{2} }{2})

M(\frac{8+3 }{2},  \frac{-7 +-1}{2} )

M(\frac{8+3 }{2},  \frac{-7 -1}{2} )

M(\frac{11 }{2},  \frac{-8}{2} )

M(5.5, -4 )

Midpoint = (5.5, -4)

Hope this helps!

Pls answer this question for ill give brainliest
notka56 [123]

Answer:

BE=15

Step-by-step explanation:

Since E is the center, BE=2x+1

And AC is 6x-12 with E being a midpoint.

Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that

you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE

6x-12=4x+2

BD=AC

6x-4x-12=2

2x=2+12

2x=14

x=7

BE= 2x+1

2(7)=14+1=15
