Answer:
- 21
Step-by-step explanation:
They lost 14 yards, then lost and additional 7 more. You would simply add and make it a negative number due to the key word " lost ".
The equation would look like this: -14 + ( -7 ).
Another way to solve this equation is to multiply. ( + ) x ( - ) = -.
Your equation will the look this this: -14 - 7.
Now you just solve.
Thus, your answer should be - 21.
Hopes the helps!
Have a great day.
Answer: -21
Step-by-step explanation:
.A football team will lose an additional 7 yards if they lost 14 on their first play.
. Since the first play resulted in a loss of 14 yards, the integers that reflect the overall change in yards for the two plays are negative.
.In the second play, we score 14 points but lose 7 yards, which is a loss of 7 points.
.Negative 14 + Negative 7 = Negative 21, which is the overall change in yards.
. Hence, the answer would be -21 yards.
. -21 would be the correct integer that will represent the the total change in yards for the two plays.

Initially, there were only 4 weeds at a park. The weeds grew at a rate of 15% each week. The following function represents the weekly weed growth: f(x) = 4(1.15)x. Rewrite the function to show how quickly the weeds grow each day and calculate this rate as a percentage.
f(x) = 4(1.15)7x; spreads at a rate of approximately 1.5% daily
f(x) = 4(1.02)7x; spreads at a rate of approximately 2% daily
f(x) = 4(1.157)x; spreads at a rate of approximately 2.66% daily
f(x) = 4(1.02)x; spreads at a rate of approximately 0.2% daily
The function to show how quickly the weeds grow each day is "f(x) = 4(1.02)7x; spreads at a rate of approximately 2% daily. Option B
How can we figure out the rate of increase in percentage terms each day?f(x) = 4(1.15)x = 4(1+ 0.15)x ................... (1)
Given that there are seven days in a week, the daily growth rate of the weeds may be estimated using equation (1) by dividing 0.15 (which stands for the 15% weekly growth rate) in the following manner:
f(x) = 4(1.15)x = 4(1+ 0.15/7)x
f(x) = 4(1 + 0.02)x
f(x) = 4(1.02)x
Since 0.02 is the same as 2%, this implies that the rate at which the weeds grow each day is 2%.

Johnson buys a newspaper each day.the cost of the newspaper is $1 per day except sunday.on sunday it cost $3. how much johnson spend on newspapers in 52 weeks.
By using the Unitary method, $468 was spent on newspapers in 52 weeks.
Unitary method is a method used for finding the unit cost in which we divide the total cost by the total number of articles and to find the cost of more than one article, we multiply the unit cost by the number of articles required.
Cost of newspapers in a week from monday to saturday = $(1 x 6) = $6
Cost of newspaper only on sunday of a week = $3
Cost of newspapers in a week = $(6 + 3) = $9
Therefore, the cost of newspapers in 52 weeks = $(52 x 9) = $468.

Answer:

Step-by-step explanation:
Hypotenuse is 13.5 the angle is 41 degrees what’s the opposite
If the length of the hypotenuse is 13.5 units and angle is 41 degrees, then the length of the opposite side is 8.86 units
The length of the hypotenuse = 13.5 units
The angle = 41 degrees
Here we have to use the trigonometric function
sin θ = Opposite side / Hypotenuse
cos θ = Adjacent side / Hypotenuse
tan θ = Opposite side / Adjacent side
In this question hypotenuse and angles are given and we have to find the opposite side.
sin θ= opposite side / Hypotenuse
Substitute the values in the equation
sin 41 = Opposite side / 13.5
Opposite side = sin 41×13.5
= 8.86 units
Hence, if the length of the hypotenuse is 13.5 units and angle is 41 degrees, then the length of the opposite side is 8.86 units.

and the constant number then find the factors that will give me the coefficient of x.
ATTACHED IS THE SOLUTION
Step-by-step explanation:
are you sure this is the whole information ?
because
6² = 5x + 6
is not called a quadratic equation.
it is a quadratic equation, when there is one term in x² involved.
I assume therefore, that your problem is
6x² = 5x + 6
that is then as basic quadratic equation
6x² - 5x - 6 = 0
the general solution to a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
a = 6
b = -5
c = -6
x = (5 ± sqrt((-5)² - 4×6×-6))/(2×6) =
= (5 ± sqrt(25 + 144))/12 = (5 ± sqrt(169))/12 =
= (5 ± 13)/12
x1 = (5 + 13)/12 = 18/12 = 3/2
x2 = (5 - 13)/12 = -8/12 = -2/3
so, the 2 solutions for the quadratic equation are
x = 3/2 and x = -2/3

Applying the slope formula, we have:
16. Slope = -9/4; Parallel slope = -9/4; Perpendicular slope = 4/9.
17. Slope = -4; Parallel slope = -4; Perpendicular slope = 1/4.
See explanation below for the rest answers.
How to Find the Slope of a Line?Slope of a line = change in y / change in x.
The slope of parallel lines are the same, while the slopes of two lines that are perpendicular to each other are negative reciprocals of each other, i.e. 1/a and -a can be the slopes of two lines that are perpendicular to each other.
In an equation given in slope-intercept form, y = mx + b, the slope is represented as "m".
16. Given, (3, 7) and (7, -2):
Slope (m) = (-2 - 7)/(7 - 3)
Slope = -9/4
Parallel slope = -9/4
Perpendicular slope = 4/9.
17. Given, y = -4x + 2,
Slope = -4
Parallel slope = -4
Perpendicular slope = 1/4.
18. Rewrite 5x - 2y = 8 in slope-intercept form:
-2y = -5x + 8
y = 5/2x - 4
Slope = 5/2
Parallel slope = 5/2
Perpendicular slope = -2/5.
19. Rewrite 4x + 3y = 2 in slope-intercept form:
3y = -4x + 2
y = -4/3x + 2/3
Slope (m) = -4/3
Substitute (a, b) = (2, -5), and m = -4/3 into y - b = m(x - a):
y - (-5)) = -4/3(x - 2)
y + 5 = -4/3(x - 2) [point-slope form]
20. Given, y = -5x + 2
Slope (m) = -5
Substitute (a, b) = (-4, -6), and m = -5 into y - b = m(x - a):
y - (-6) = -5(x - (-4))
y + 6 = -5(x + 4) [point-slope form]
21. Rewrite 9x - 3y = 6 in slope-intercept form:
-3y = -9x + 6
y = 3x - 2
The slope of y = 3x - 2 (9x - 3y = 6) is 3.
The slope of -3x - 5 is -3.
