Answer:
Step-by-step explanation:
So we know that Alex is trying to save $230.
He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.
If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.
38×5= 190
Therefore, Alex will have enough money to buy a tablet in five weeks.
I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

Factorise
x^2+18x+80
Answer:
(x + 10)(x + 8)
Step-by-step explanation:
Given
x² + 18x + 80
Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)
The factors are + 10 and + 8 , since
10 × 8 = + 80 and 10 + 8 = + 18 , then
x² + 18x + 80 = (x + 10)(x + 8) ← in factored form
Graph the line that passes through the points (1,-9) and (1,-3) and determine the equation of the line
Answer:
x = 1
Step-by-step explanation:
Note that the x-coordinates of the two given points are identical. This tells us immediately that the line is a vertical one whose slope is undefined.
The equation of this line is x = 1.
Veronica cut a triangular piece of cookie cake with side lengths that measure 3.6 cm, 6 cm and 4.8cm.

Answer:3.6 + 4.8 > 6
Step-by-step explanation:
The answer is YES, the triangle that is cut down by Veronica is a right triangle.
What is a triangle?The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.
As per the given information in the question,
The lengths of the sides of the triangle are given as,
Let Base, b = 3.6 cm
Perpendicular, p = 4.8 cm
Hypotenuse, h = 6 cm
Now, use the equation of Pythagoras' theorem,
h² = p² + b²
6² = 4.8² + 3.6²
36 = 23.04 + 12.96
36 = 36
It satisfies Pythagoras' theorem, which means that it is a right triangle.

Amanda plans on going to the amusement park this Friday. It costs $25.00 to
enter the park, and then $1.25 for every ride that Amanda goes on. What will be
the total cost if Amanda goes on 9 rides?
Answer:
$36.25
Step-by-step explanation:
To enter the park, Amanda pays 25 dollars.
+$25
It costs 1.25 for every ride that Amanda goes on.
Since we don't know the number of rides Amanda goes on, we will add a variable to represent the number of rides.
1.25x
Then, the passage says that Amanda goes on 9 rides. So, substitute 9 for x.
Equation: 25+1.25(9)
Then solve:
$36.25
A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *
9514 1404 393
Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property
y = x^2 +4x -2x -8 . . . . use the distributive property again
y = x^2 +2x -8 . . . . . . . .equation in standard form

Continue the pattern by filling in the next 3 terms
-5, -2, 1,
Answer:
4, 7, 10
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 2 - (- 5) = 1 - (- 2) = 3
To obtain a term in the sequence add d = 3 to the previous term, then
a₄ = a₃ + 3 = 1 + 3 = 4
a₅ = a₄ + 3 = 4 + 3 = 7
a₆ = a₅ + 3 = 7 + 3 = 10

The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
What is the value of y when x 5 and z = 12?
A. 540
B. 9
C. 153
D. 450
Answer:
A
Step-by-step explanation:
Joint variation is given by:
[tex]y=kxz[/tex]
Where k is some constant.
We are given that y = 360 when x = 4 and z = 10. Therefore:
[tex]360=k(4)(10)[/tex]
Solving for k:
[tex]40k=360\Rightarrow k=9[/tex]
Therefore, our equation is:
[tex]y=9xz[/tex]
Then when x = 5 and z = 12:
[tex]y=9(5)(12)=540[/tex]
