Answer:
no
Step-by-step explanation:
10² + 24² ≠ 28²
Answer:
y = (-3/2) x + 3
Step-by-step explanation:
The line passes through (0, 3) and (2, 0)
Slope = (0 - 3)/(2 - 0) = -3/2
Let y = (-3/2) x + b
Use (0, 3) to get b:
3 = (-3/2)*0 + b, so b = 3
Then y = (-3/2) x + 3
Answer:
the length is 22 and the width is 18
Step-by-step explanation:
The perimeter is 2(l) + w(2)
w is the width and l is the length
if you plug in 22 and 18 you get
2(22)+(2)18
then you do multiplication to get
44+36
then you add and you get 80
Answer:
(c) y < x^2 -5x
Step-by-step explanation:
A quadratic inequality is one that involves a quadratic polynomial.
<h3>Identification</h3>
The degree of a polynomial is the value of the largest exponent of the variable. When the degree of a polynomial is 2, we call it a <em>quadratic</em>.
For the following inequalities, the degree of the polynomial in x is shown:
- y < 2x +7 . . . degree 1
- y < x^3 +x^2 . . . degree 3
- y < x^2 -5x . . . degree 2 (quadratic)
<h3>Application</h3>
We see that the degree of the polynomial in x is 2 in ...
y < x^2 -5x
so that is the quadratic inequality you're looking for.

<em>Additional comment</em>
When a term involves only one variable, its degree is the exponent of that variable: 5x^3 has degree 3. When a term involves more than one variable, the degree of the term is the sum of the exponents of the variables: 8x^4y3 has degree 4+3=7.
Hello!
ANSWER:
36 students have a dog as a pet, and 30 students have a cat as a pet.
EXPLANATION:
Let's quickly convert these fractions to decimals by dividing their numerators by their denominators.
4 ÷ 5 = 0.8
2 ÷ 3 = 0.6666666667
Now, multiply the decimal forms by the number of students in Mrs. Hu's class.
0.8 × 45 = 36
0.(6)7 × 45 = 30
