Answer:If I’m correct I believe seven you cars for 16.45 would be better

Step-by-step explanation:

Since three cars cost 7.50 you would divide 7.50 to get the cost for each car which would give you 2.50 and since seven cars cost 16.45 you would divide 16.45 by 7 to get the cost of each car which would come out to 2.35 making it a better buy

What is the measure of segment eb ?

Nady [450]

We know that
When two chords intersect each other inside a circle, the products of their segments are equal (Intersecting Chord Theorem)
so
in this problem
AE*EB=DE*EF----> EB=DE*EF/AE
AE=4 in
DE=12 in
EF=8 in
EB=?

EB=DE*EF/AE-----> EB=12*8/4----> EB=24 in

the answer is
EB=24 in

Trey evaluated 12/15 + 1/10 and got the answer of 13/25. which statement is true about this answer?

Ganezh [65]

Answer:

Option C. His answer is not correct, because the same can not be less than either attend

Step-by-step explanation:

we have

$\frac{12}{15}+\frac{1}{10} =\frac{13}{25}$

we know that

$\frac{12}{15}=0.8$

$\frac{1}{10}=0.10$

$\frac{13}{25}=0.52$

substitute

$0.80+0.10=0.52$ ----> is not true

therefore

His answer is not correct, because the same can not be less than either attend

Find the average rate of change of the function from x=1 to x=2. f(x)=−14/x^2

Irina-Kira [14]

Answer:

The average rate of change of the function from x=1 to x=2 will be: 10.5

Step-by-step explanation:

Given the function

$f\left(x\right)=-\frac{14}{x^2}$

at x₁ = 1,

f(x₁) = f(1) = -14/(1)² = -14/1 = -14

at x₂ = 2,

f(x₂) = f(2) = -14/(2)² = -14/(4) = -3.5

Using the formula to determine the average rate of change at which the total cost increases will be:

Average rate of change = [f(x₂) - f(x₁)] / [ x₂ - x₁]

= [-3.5 - (-14)] / [2 - 1]

= [-3.5 + 14] / [1]

= 10.5 / 1

= 10.5

Therefore, the average rate of change of the function from x=1 to x=2 will be: 10.5
