We can Split the Middle Term of this expression to factorise it.
In this technique, if we have to factorise an expression like
a
x
2
+
b
x
+
c
, we need to think of 2 numbers such that:
N

⋅
N

=
a
⋅
c
=

⋅
3
=
9
and,
N

After trying out a few numbers we get:
N

=

and
N

Gina has been offered a job as a dog walker. Each week Gina works, she gets a flat amount of $10, plus an additional $5 per dog walked. Gina's goal is to earn at least $75 each week. Which inequality can be used to find the number of dogs Gina must walk in a week in order to reach her goal?
Answer:
13
Step-by-step explanation:
Given data
flat amount =$10
let the number of dogs walked be x
and let the money earned be y
y= 10+5x
for y= 75
let us find x
75= 10+5x
75-10= 5x
65= 5x
divide both sides by 5
x= 65/5
x=13
Hence the number of dogs is 13

Step-by-step explanation:
Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
A bank uses positive numbers to represent deposits and negative numbers to represent withdrawals. How would a bank represent a withdrawal of 19.4319.4319, point, 43 dollars?
Answer:
- $19.43
Step-by-step explanation:
Withdrawals are represented by negative values (-)
Deposits are represented by positive values (+)
To represent a withdrawal of $19.43
It would be represented as - $19.43

Quadrilateral WXYZ has vertices W(–3, 4), X(–3, 1), Y(2, 1), and Z(2, 4). What are the coordinates of the image of point W after a reflection across the y-axis?
A. w-(3, 4)
B. w- ( 3 , - 4 )
C. w- ( - 3 , - 4 )
D. w- ( 4 , - 3 )
Answer: A
Step-by-step explanation:
When you reflect over the Y axis you do (-x,y)
And so (-3,4) = (3,4)

Lynn is making a snack. The recipes call for 3/8 cup of water for oats and 1/4 cup of water for dried fruit. She only has 1 cup of water. Does she have enough to make her snack? Explain
Answer: She has enough.
Step-by-step explanation:
You need to add up the quantities of water needed first. That will then tell if she has enough water.
Convert the fractions to decimals then add them up:
3/8 = 0.375
1/4 = 0.25
= 0.25 + 0.375
= 0.625 cups of water is required.
This is less than the 1 cup she has so she has enough water to make the snack.

Sister asked this: shes 10
whats 3/4 + 1/8
Answer:
1/2 or 1/3
Step-by-step explanation:
if you add them across you will get 4/12 which you would simplify and it will give you 1/3 but if you keep the bottem numbers as 8 then add 3 and 1 it will give you 4/8 simplify that's and it gives you 1/2

What is the vertical asymptote
Answer:
Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. It will be the red ones
Step-by-step explanation:
(They can also arise in other contexts, such as logarithms, but you'll almost certainly first encounter asymptotes in the context of rationals.)

Maximum and Minimum Values of General Quadratic Functions
1. By expressing y = 2x^2 + 4x + 17 in the form y = a(x + b)^2 + C, where a, b, and c are constants, state the minimum value of y and the value of x at which this occurs. Hence, sketch the curve y = 2x^2 + 4x + 17
x =
y =
Answer:
x=-1
y=15
Step-by-step explanation:
This works because completing the square is essentially demonstrating what g(x) - where g(x) in this case = x^2 - would have to be translated by to give the function you have.
So by completing the square you have shown that the function you've been given has been shifted to the left by -1, stretched by a factor of 2 along the y axis and shifted up by 15.

Answer:
362.35N/m²
Step-by-step explanation:
Pressure = Force/Area
Area = πr²
Area = 3.14(0.75)²
Area = 3.14(0.5625)
Area = 1.76625m²
Force = 640N
Pressure = 640/1.76625
Pressure = 362.35N/m²

Step-by-step explanation:
Δ AEB and Δ ADC are similar, so ratios of corresponding sides are equal, that is
[tex]\frac{AB}{AC}[/tex] = [tex]\frac{AE}{AD}[/tex] , substitute values
[tex]\frac{9.2}{AC}[/tex] = [tex]\frac{9}{14}[/tex] ( cross- multiply )
9AC = 128.8 ( divide both sides by 9 )
AC ≈ 14.3 (to the nearest tenth )
