Step-by-step explanation:
Use substitution to solve the system of equations.
5x + y = -24
x + 3y = -2
• A X=-5. y = -1
• B. x = 5, y = 1
• C. x=-5, y = 1
• D. x = 5, y = -1
o
B

D
the answer should be C.x=-5,y=1
The functions g and h are given by g(x) = x + 1 and h(x) = x²
Find the values of x for which hg(x) = 3x² + x - 5
Answer:
x = - [tex]\frac{3}{2}[/tex] , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]
x - 2 = 0 ⇒ x = 2

Answer:
w+6=8 and w=2
Step-by-step explanation:
2(w+6) = 16
divide by two on both sides to remove the 2
w+6=16/2
w+6=8
-6 (remove six from both sides)
w=2

. Cost. A circular terrace has a radius of 6 ft. If it costs $1.50 per square foot to pave the terrace with brick, what will the total cost be?
Answer:
$169.65 is the total cost
Step-by-step explanation:
A= πr2= π·6(2)≈ 113.1
113.1 * 1.50 = 169.65
If a vector gets multiplied by a negative number then its direction
A. remain same
B. gets reversed
C. gets half
D. gets double
Answer:
I believe it is B
Step-by-step explanation:
Answer:
B. gets reversed
Step-by-step explanation:
except that multiplying by a negative number will reverse the direction of the vector's arrow. For example, multiplying a vector by 1/2 will result in a vector half as long in the same direction, while multiplying a vector by −2 will result in a vector twice as long but pointed…

how do i get 60% out of 60/100?
Answer:
Calculator 1: Calculate the percentage of a number.
For example: 60% of 100 = 60
Calculator 2: Calculate a percentage based on 2 numbers.
For example: 60/100 = 60%
6x + 2(7x – 4) = 92 I T
Answer:
x = 5
Step-by-step explanation:
6x + 2(7x – 4) = 92
simplify:
6x + 14x - 8 = 92
20x = 100
x = 5
Answer:
6x+2(7x−4)=92
Step 1: Simplify both sides of the equation.
6x+2(7x−4)=92
6x+(2)(7x)+(2)(−4)=92(Distribute)
6x+14x+−8=92
(6x+14x)+(−8)=92(Combine Like Terms)
20x+−8=92
20x−8=92
Step 2: Add 8 to both sides.
20x−8+8=92+8
20x=100
Step 3: Divide both sides by 20.
100
20
x=5
The question is in the picture
Answer:
y= -5x+7
Step-by-step explanation:
since it is parallel, the gradient is the same
m=-5
y=mX+C
y=-5x + c
sub in the coordinate to get the y intercept
(2)= -5(1)+c
2+5 = C
C=7
therefore the ans is :
y= -5x + 7

Step-by-step explanation:
Let the function f(x) have the form f(x) = Acos(x-C). To produce a graph that matches the one shown below, what must the value of C be?
Answer: Option B, C = 3.
Step-by-step explanation:
Here we have the function:
f(x) = A*cos(x - C)
A is the amplitude, and we can easily see that the amplitude is 2.
Then:
f(x) = 2*cos(x - C)
We also can see that when x = 0, f(x) ≈ -2
This means that:
cos(0 - C) ≈ -1
Cos(C) ≈ -1
Now we can just evaluate in the different options and see which one is the correct option.
Cos(1) = 0.54
Cos(2) = -0.42
Cos(3) = -0.99
Cos(4) = -0.65
The closer option to -1 is when C = 3, then the correct option is option B.

B

A recipe for beef fajitas uses 5 pounds of beef to make 20 meals. How many pounds of beef are needed to make 80 meals?
Answer: 0.25 pound of beef are needed to make 80 meals.
Step-by-step explanation:
Given : A recipe for beef fajitas uses 5 pounds of beef to make 20 meals.
Then the of beef required for 1 mesal = ( 5 pounds) ÷ 20
= [tex]\dfrac{5}{20}[/tex] pound
[tex]=\dfrac{1}{4} [\text{Divide numerator and denominator}][/tex]
=0.25 pound
Hence, 0.25 pound of beef are needed to make 80 meals.
Which point is best represented by the ordered pair (2, -5.5)?
A point W
b point V
c point S
d point R
Answer:
B
Step-by-step explanation:
Answer:
The answer is A, Point W.
This is because (2, -5.5) is equal to (x, y). So, x would be 2, while point y will be -5.5. Point W represents this because it goes to 2 on the x axis, and down to -5.5 on the y axis.
Can someone give me the answer and explanation
Answer: A
Step-by-step explanation:
The total minus the cost of the eggs leaves you with just the total of the potatoes. Since we know that the total of the potatoes is the product of 5 bags, we can divide the total of the potatoes by 5 to find the cost of each bag of potatoes.

Which property is being demonstrated?
quotient of powers property
power of a product property
product of powers property
power of a quotient property
Answer:
A.
Step-by-step explanation:
We see a fraction. A fraction means a division, and the result of a division is called a quotient. We know we have a quotient.
We have two choices with "quotient."
A. quotient of powers property
D. quotient of powers property
We need to choose A or D.
A. quotient of powers means a division of powers. That is what we see with the fraction. A power in the numerator, and a power in the denominator. We have a division of powers, so it is a quotient of powers.
D. power of a quotient. This is take a fraction which is a quotient, and raise the entire fraction to an exponent. This is not what we have.
Answer: A.

Step-by-step explanation:
classify and degree 2x+7
Answer:
Number of terms.
A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.
A binomial has two terms. For example: 5x2 -4x
A trinomial has three terms. For example: 3y2+5y-2
Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2
Practice classifying these polynomials by the number of terms:
1. 5y
2. 3x2-3x+1
3. 5y-10
4. 8xy
5. 3x4+x2-5x+9
Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial
2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

Give the number of terms:
cd + 3d2 – 2d
Give the number of terms
Answer:
3
Step-by-step explanation:
Given the expression
cd + 3d2 – 2d
We are to determine the number of terms
From the equation, the term so of the expression are cd, 3d^2 and -2d. From the listed functions, we can see that we only have three of them. Hence the number of terms in the expression is 3
