The first equation should be multiplied by 7 and the second equation by -6. The correct option is C.
What is an expression?In mathematics, an expression is a group of symbols (variables, constants, and mathematical operations) used to represent a quantity or a relationship between two numbers.
In order to eliminate the x terms and find y in the fewest steps feasible, the equations should be multiplied by constants such that the coefficient of x in one equation is equal to the negative coefficient of x in the other.
The coefficients of x in the first and second equations in this situation are 6 and 7, respectively. To make these coefficients opposite in sign, we can multiply the first equation by 7 and the second equation by -6.
The correct solution is obtained by multiplying the first equation by 7 and the second equation by -6.

Solve for a.
a+(−4)=−13
a=−17
a=−9
a = 9
a = 17
Answer:
a = -9
Step-by-step explanation:
a+(-4)=-13
add 4 to each side
a-4+4 = -13+4
a = -9
Answer:
a = - 9
Step-by-step explanation:
a + (-4) = -13
Add 4 to both sides
a + (-4) + 4 = -13 + 4
a + 0 = -9
a = -9

Which is the directrix of a parabola with equation x2 = 8y?
O y = 2
O X=-2
O y=-2
O X=2
Answer:
Y=-2
Step-by-step explanation:
You would use the vertex form to find the directrix
The directrix is a horizontal line that is y = -2.
Option C is the correct answer.
What is a parabola?A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.
The equation of a parabola:
y = a(x-h)^2 + k
We have,
The directrix of the parabola with equation x^2 = 8y is a horizontal line, and its distance from the vertex is equal to the value of the parameter p.
To find the value of p, we need to rewrite the equation of the parabola in the standard form:
x² = 8y
Dividing both sides by 8, we get:
x²/8 = y
Comparing this equation to the standard form of a parabola with a horizontal axis of symmetry, which is given by (y-k)² = 4p (x-h), we can see that h = 0, k = 0, and p = 2.
Therefore,
The directrix is a horizontal line that is 2 units below the vertex, which is located at (0,0).
i.e
y = -2.

Write the correct colours to complete these sentences.
The probability that it will be ..................... is 0.2
The solution is 4 green
The probability of choosing a green counter from the bag is 0.2
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
Let the probability of choosing a green counter be = P
Now , the value of P is
Let the total number of blue counters be G = 2
Let the total number of green counters be G = 4
Let the total number of red counters be G = 5
Let the total number of yellow counters be G = 9
So , the total number of counters = number of blue counters + number of green counters + number of red counters + number of yellow counters
Substituting the values in the equation , we get
The total number of counters = 2 + 4 + 5 + 9
The total number of counters = 20
Now , the probability of choosing the green counter P = total number of green counters / total number of counters
Substituting the values in the equation , we get
Probability of choosing the green counter P = 4/20
Probability of choosing the green counter P = 2/10
Probability of choosing the green counter P = 0.2
Therefore , the value of P is 0.2
Hence , the probability of choosing green counter is 0.2

x = 36
Find the values of x, y, and z.
Answer:
x = 20°
y = 160°
z = 160°
Step-by-step explanation:
x = 20°
(Measure of arc is equal to the measure of its corresponding central angle)
z = 180° - 20°
(Linear pair angles)
z = 160°
y = z
(Measure of arc is equal to the measure of its corresponding central angle)
y = 160°

O A. (x – 4)(x - 5)
O B. (x-2)(x+10)
O C. (x - 2)(x - 10)
O D. (x – 4)(x + 5)
The factorization of the given trinomial [tex]x^2 - 9x+ 20[/tex] is (x – 4)(x - 5). The correct option is A.
What is trinomial?A trinomial is a polynomial that has three terms. To factor a trinomial of the form [tex]ax^2 + bx + c[/tex], you need to find two binomials that multiply together to produce the original trinomial.
To factor the trinomial [tex]x^2 - 9x + 20[/tex], we need to find two numbers that multiply to 20 and add up to -9. These two numbers are -4 and -5. Therefore, we can write:
[tex]x^2 - 9x + 20 = (x - 4)(x - 5)[/tex]
Or, To factor [tex]x^2 - 9x + 20[/tex], you need to find two numbers that multiply to 20 and add up to -9. These numbers are -4 and -5 because -4*(-5) = 20 and -4 + (-5) = -9.
You can factor the trinomial as (x - 4)(x - 5).
Thus, the correct option is A.
