y=[tex]4x^{2}[/tex]+3x+4
y=5x+4
Answer:
(0, 4 ) and ( [tex]\frac{1}{2}[/tex], [tex]\frac{13}{2}[/tex] )
Step-by-step explanation:
Given the2 equations
y = 4x² + 3x + 4 → (1)
y = 5x + 4 → (2)
Substitute y = 4x² + 3x + 4 into (2)
4x² + 3x + 4 = 5x + 4 ( subtract 5x + 4 from both sides )
4x² - 2x = 0 ← factor out 2x from each term
2x(2x - 1) = 0
Equate each factor to zero and solve for x
2x = 0 ⇒ x = 0
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
Substitute these values into (2) for corresponding values of y
x = 0 : y = 5(0) + 4 = 0 + 4 = 4 ⇒ (0, 4 )
x = [tex]\frac{1}{2}[/tex] : y = [tex]\frac{5}{2}[/tex] + 4 = [tex]\frac{13}{2}[/tex] ⇒ ([tex]\frac{1}{2}[/tex], [tex]\frac{13}{2}[/tex] )

Y= 8x +3 What is the slope and y-intercept of the equation? Slope = 8; y-intercept = (3, 0) Slope = 3; y-intercept = (0, 8) Slope = -8; y-intercept = (0, 3) Slope = 8; y-intercept = (0, 3)
Answer:
Slope = 8 Y-intecept = (0, 3)
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y intercept value
y = 8x + 3
m = 8
y = 3

Write an algebraic expression to model the given context. Give your answer in simplest form. the price p of a coat reduced by a 5% discount
Answer:
We conclude that the expression of the price p of a coat reduced by a 5% discount will be: 0.95 p
Step-by-step explanation:
Let 'p' be the original price
Discount = 5% = 0.05
The discount amount can be calculated by multiplying the original price by 5% or 0.05
Discount Amount = 5% × p
= 0.05 × p
= 0.05 p
Given that the price p of a coat reduced by a 5% discount.
Thus, the price after 5% discount can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.
Thus,
The expression of the price p after 5% discount = p - 0.05 p
= 0.95 p
Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount will be: 0.95 p
how to multiply and add number subtracting them and equating them
Answer:
Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are: Multiply and divide from left to right. Add and subtract from left to right.
Step-by-step explanation:
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.
Answer:

Work out the surface area of the solid cuboid
H=2cm
W=4cm
L=5cm
Answer:
total surface area = 76 sq.cm
Step-by-step explanation:
total surface area of cuboid = 2 ( lb + lh + bh )
( where l is length , b is width and h is height )
so, surface area :
= 2[ (5×4) + (5×2) + (2×4) ]
= 2 [ 20 + 10 + 8 ]
= 2 × 38
= 76 sq.cm
Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds how many pounds of his weight is made up of fat round your answer to the nearest 10th
Answer:
26.7pounds
Step-by-step explanation:
Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds
This is calculated as:
Pounds of his weight that is made up of fat is calculated as
Body fat percentage × Body weight in pounds
= 15.9% × 168 pounds
= 15.9/100 = 168 pounds
= 26.712 pounds
Approximately to the nearest tenth = 26.7 pounds

Two triangles are similar.The the smaller triangle has side 10,20 and 15 units the larger triangles longest side is 52 units.What is the perimeter of the largest triangle?
Answer: The perimeter of the largest triangle = 117 units.
Step-by-step explanation:
Sides of smaller triangle = 10,20 and 15 units
Longest side = 20 units
Longest side of larger triangle = 52 units
Sides of two similar triangles are proportional.
Let k be proportionality constant.
[tex]k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}[/tex]
[tex]k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}[/tex]
Length of other two sides,
[tex]10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}[/tex]
So sides of larger triangle = 52 units, 26 units , 39 units
Perimeter of largest triangle = 52 +26+39 = 117 units
Hence, the perimeter of the largest triangle = 117 units.

A telephone poll of an SRS of 1234 adults found that 62% are generally satisfied with their lives. The announced margin of error for the poll was 3%. Does the margin of error account for the fact that some adults do not have telephones
Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling

A rental car company charges $68.64 per day to rent a car and $0.12 for every mile driven. Jaxon wants to rent a car, knowing that: • He plans to drive 500 miles. • He has at most $210 to spend. What is the maximum number of days that Jaxon can rent the car while staying within his budget?
Answer:
2 days
Step-by-step explanation:
According to the problem, calculations of given data are as follows,
Rental charges per day = $68.64
Rental per mile = $0.12
Total miles = 500
Total spend = $210
Let number of days = X
So, we can find number of days by using following equation,
($68.64 × X ) + ( $0.12 × 500) = $210
$68.64 X + $60 = $210
$68.64 X = $210 - $60
$68.64 X = $150
X = $150 ÷ $68.64
X = 2.18 or 2 Days
