An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The system of equations to find the cost of large and small candles are,
4x + 3y = 34
2x + y = 16
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: 2x + 4 - 8 is an equation.
We have,
At Yankee Candle, four large candles and three small candles sell for $34. For two large candles and one small candle, the cost is $16.
Large candles = x
Small candles = y
Now,
4x + 3y = 34
2x + y = 16
Thus,
The system of equations to find the cost of large and small candles are,
4x + 3y = 34
2x + y = 16
Option D is the correct answer.

Is x + 5 a factor of P(x) = x ^ 3 + 4x ^ 2 + 2x + 35
Answers
Answer:
yes
Step-by-step explanation:
If ( x + 5) is a factor of p(x) then p(- 5) = 0
p(- 5)
= (- 5)³ + 4(- 5)² + 2(- 5) + 35
= - 125 + 100 - 10 + 135
= 0
Since p(- 5) = 0 then (x + 5) is a factor of p(x)
Answer:
(x +5 ) is a factor
Step-by-step explanation:
x + 5 = 0
x = -5
P(x) = x³ + 4x² + 2x + 35
P(-5) = (-5)³ + 4*(-5)² + 2*(-5) + 35
= -125 + 4*25 - 10 + 35
= -125 + 100 - 10 + 35
= -25 -10 +35
= -35 + 35
= 0
P(-5) = o. So, (x +5 ) is a factor

Required
The number of puppies in the kennel
Step two:
Let us the part to all method to find the number of puppies
let the number of puppies be x
2/5=x/65

Need to know the following angle
Answers
Given:
[tex]m\angle A=(2x-15)^\circ[/tex]
[tex]m\angle B=(x-5)^\circ[/tex]
[tex]\text{Exterior}\ m\angle C=148^\circ[/tex]
To find:
The [tex]m\angle ABC[/tex].
Solution:
In triangle ABC,
[tex]\text{Exterior}\ m\angle C=m\angle A+m\angle B[/tex] [Exterior angle theorem]
[tex]148=(2x-15)+(x-5)[/tex]
[tex]148=3x-20[/tex]
[tex]148+20=3x[/tex]
[tex]168=3x[/tex]
Divide both sides by 3.
[tex]\dfrac{168}{3}=x[/tex]
[tex]56=x[/tex]
Now,
[tex]m\angle ABC=(x-5)^\circ[/tex]
[tex]m\angle ABC=(56-5)^\circ[/tex]
[tex]m\angle ABC=51^\circ[/tex]
Therefore, [tex]m\angle ABC=51^\circ[/tex].

Step 2. X-4 = 0 and x - 2 = 0
Step 3. x = 4 and x = 2
A. in Step 2
B. in Step 1
C. The student did not make any mistakes, the solution is correct
D. in Step 3
Answers
Answer:(b) step 1
Step-by-step explanation:
The wrong step in the student's workings is step 1
How to determine the wrong step?The equation is given as:
x^2 - 2x - 8 = 0
Expand the equation
x^2 + 2x - 4x - 8 = 0
Factorize the equation
x(x + 2)- 4(x + 2)
Factor out x + 2
(x - 4)(x + 2) = 0
The above means that the factored equation of x^2 - 2x - 8 = 0 is (x - 4)(x + 2) = 0
This means that the step 1 of the student's step is wrong and incorrect
