Find an ordered pair (x, y) that is a solution to the equa
4x - y = 5
Answer:
(xy) (xy) (1−1) (2 3)
Step-by-step explanation:
Slope 4 intercept is -5 we can rearrange with 4x-y=5
We then work out y= -5+ 4x and y=4x−5
We know there is a 4 intercept and we are ready in negatives -5
The slope goes up again by 4 after -1
4+-1 = 3 to find y
We find x by plugging in these values 3(-1) = 2
The required solution as ordered pairs to the given equation 4x - y = 5 are (5/4,0) and (0,-5)
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The equation is given in the question
4x - y = 5 ....(i)
We have to determine the ordered pair (x, y) that is a solution to the given equation.
Two that to find are (a,0) and (0,b); these points are/contain the x and y intercepts.
Substitute the point coordinate values for x and y in the equation and solve for the remaining variable.
Substituting into the given equation (i):
(a,0): 4a - 0 = 5 ⇒ a = 5/4 and (a,0) = (5/4,0)
(0,b): 4(0) - b = 5 ⇒ b = -5 and (0,b) = (0,-5)
Therefore, the required solution as ordered pairs to the given equation 4x - y = 5 are (5/4,0) and (0,-5)

A polynomial function has a root of 5 with multiplicity 3, a root of 1 with multiplicity 2, and a root of 3 with multiplicity 7. If th
function has a negative leading coefficient and is of even degree, which statement about the graph is true?
O The graph of the function is positive on (-0, -5).
O The graph of the function is negative on (-5, 3)!
O The graph of the function is positive on (-0, 1).
O The graph of the function is negative on (3,co).
Answer:
The graph of the function is negative on (3,0)
Step-by-step explanation:
The limiting behavior of a function describes how a function behaves as x ⇒ ±∞. Its behavior is determined by the degree of a polynomial and the sign of its leading coefficient.
Since the function [f(x)] is an even degree polynomial with negative leading coefficient, then f(x) ⇒ -∞ as x ⇒ ±∞. The graph of the function is negative at the root. Since it has a root of 3, The graph of the function is negative on (3,0)
Answer:
The graph of the function is negative on (3, infinity) The answer is D

A shop is having a sale.
All items are reduced by 30%
Work out the sale price of an item normally priced at £110
Answer:
77
Step-by-step explanation:
10%=11
because you divide 110 by 10.
Then i would multiply that by 3, giving you 33
110-33=77
The sale price of an item normally priced at £110 is £77.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that all items are reduced by 30% on a sale.
An item that normally priced at £110 reduced by 30%.
So, 30 percentage of £110
= 30% of £110
= 110×30/100
= 3300/100
= 33.
Therefore, the sale price of an item normally priced at £110 is £77.

After triangle ace is dilated by a factor of 5, it has an area of 100 square inches. What was its area before dilation?
Answer:
20in^2
Step-by-step explanation:
Since you multiply the original area of the triangle by the scale factor to get the new area, you can find the original area (before dilation) by dividing the dilated triangle's area by the scale factor. Since 100 is the area of the dilated triangle, and 5 is your scale factor, you do 100/5 to get the area of the triangle before it was dilated.

The amount of paint needed to cover a wall is proportional to its area. The wall is rectangular and has an area of 4z2 + 2z square meters. Factor this polynomial to find possible expressions for the length and width of the wall. (Assume the factors are polynomials.)
Answer:
2z(2z+1)
Step-by-step explanation:
Write the equation for the area and then factor the polynomial to find the possible expression for the length and width.
A = 4z2 + 2z The GCF of 4z2 and 2z is 2z.
= 2z(2z) + 2z(1) Write the terms as products using the GCF as a factor.
= 2z(2z + 1) Use the distributive property to factor out the GCF. Possible expressions for the dimensions of the wall are 2z m and (2z + 1) m.
The requried expression of the length and width is (2z + 1) and 2z.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
As mentioned in the question, the amount of paint needed to cover a wall is proportional to its area.
The wall is rectangular and has an area of 4z² + 2z square meters. According to the question, we have factored this polynomial to find possible expressions for the length and width of the wall.
So,
Area = 4z² + 2z
Takin common 2z
Area = 2z × (2z + 1)
Comparing the above expression with
Area of rectangle = width × length
From comparison,
Length = (2z + 1)
Width = 2z
Thus, the requried expression of the length and width is (2z + 1) and 2z.

In a classroom there are 15 boys and 13 girls. One of the girls Samantha moved away. What percent of the classroom are girls after Samantha moved.
Answer: 44%
Step-by-step explanation: First, let's add up all the children in the classroom...
15 + 12 = 27
There's 15 boys, therefore have to divide 15 by 27...
15 ÷ 27 = 0.55 x 100 = 55%
Now, let's divided the total amount of girls...
12 ÷ 27 = 0.44 x 100 = 44%
44 + 55 = 99%
The perecent of girls in the classroom are 44%, I hope this helps!
