Step-by-step explanation:

Takes 6 days to eat 1 apple so multiply 6 by three to get your answer.

Answer:

18 days

Step-by-step explanation:

Find the y-intercept and the axis of symmetry of:
f(x) = ax^2 + 8ax - 5

Answers

Answer:

y-intercept (0,-5) and AOS x = -4

Step-by-step explanation:

To find the y-int make x = 0 so f(0) = -5

The axis of symmetry (AOS) can be found by the equation x = -b/2a

So AOS = -8a / 2a, so AOS = -4 since b=8a and a = a

solve the equation
3b/7 -1 = 5

Answers

Answer:

b = 14

Step-by-step explanation:

The required solution to the equation 3b/7 - 1 = 5 is b = 14.

What is simplification?

Simplification involves directions of arithmetic and algebra to remove disproportionate terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property

Here,
To solve for b, we need to isolate b on one side of the equation.

First, we add 1 to both sides of the equation to get:

3b/7 = 5 + 1

Simplifying the right-hand side:

3b/7 = 6

Next, we multiply both sides by 7/3:

(7/3) * (3b/7) = (7/3) * 6

Simplifying:

b = 14

Therefore, the solution to the equation 3b/7 - 1 = 5 is b = 14.

A) By using the Pythagorean Theorem, we will see that [tex]8^2 + 15^2 = 17^2[/tex]. If we simplify it, we will find that the hypotenuse of Δ[tex]ABC = 17[/tex]

B) approximately [tex]18.79[/tex]

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is [tex]leg^2 + leg^2 = hypotenuse^2[/tex]

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, [tex]8^2 + 17^2 = AD[/tex].

[tex]8^2 + 17^2 = 64 +289[/tex][tex]64 + 289 = 385[/tex][tex]\sqrt{385} \\[/tex] ≈ [tex]18.79[/tex]
