Answer:
number of dimes is 8
number of quarters is 15
Step-by-step explanation:
let 'd' = number of dimes
let 'd+7' = number of quarters
.10d + .25(d + 7) = 4.55
.10d + .25d + 1.75 = 4.55
.35d = 2.80
d = 8
q = 7 + 8

[tex](\frac{dy}{dx})_{x=-1} = e^{-5}[/tex]
Step-by-step explanation:
Explanation:-
Given function
y = f(x) = e ˣ⁻⁴ ...(i)
Differentiating equation (i) with respective to 'x' , we get
[tex]\frac{dy}{dx} = e^{x-4} \frac{d}{dx} (x-4)[/tex]
[tex]\frac{dy}{dx} = e^{x-4} (1)[/tex]
Slope of the tangent line
[tex](\frac{dy}{dx})_{x=-1} = e^{-1-4} = e^{-5}[/tex]

Hello!
[tex]\large\boxed{x = 4.21in}[/tex]
Use the Pythagorean Theorem to solve:
a² + b² = c²
We are given the Hypotenuse (c) and one of the legs (b), so we can plug those values in to solve for a:
a² + (6.8)² = 8²
a² + 46.24 = 64
Subtract 46.24 from both sides:
a² = 17.76
Square root both sides:
a = √17.76
a ≈ 4.21 = x

- 4x +35> 2 What is the answer?
Answer:
x < [tex]\frac{33}{4}[/tex]
Step-by-step explanation:
Given
- 4x + 35 > 2 ( subtract 35 from both sides )
- 4x > - 33
Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity.
x < [tex]\frac{33}{4}[/tex]

You spend c dollars for p identical pairs of pants. A friend claims that because c increases if you increase p and p increases if you increase c either c or p could be the independent variable. Is your friend right or wrong? Explain.
Answer:
Your friend is wrong.
Step-by-step explanation:
Since we have that you spend c dollars for p identical pairs of pants. We can represent this using:
C = kP.
Where k is the price for one pair of pants whereby the amount of dollars you spend depends on the number of pants picked.
C is the dependent variable here, depending on P and P is independent. Therefore, you have only one independent variable which is P.

If ABCD is dilated by a factor of 2 the coordinate of b would be? Will mark barinlyist.
Answer:
B'(- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
Jazmine can run 4 5/6 miles in 2/3 of an hour. How many miles can she run in 1 hour?
Answer: she can run [tex]6\dfrac54[/tex] mile sin 1 hour.
Step-by-step explanation:
Given : Distance run by Jasmine in [tex]\dfrac23[/tex] of an hour = [tex]4\dfrac56\text{ miles}=\dfrac{24+5}{6}\text{ miles}[/tex]
[tex]=\dfrac{29}{6}[/tex] miles
Distance run by Jasmine in 1 hour = [tex]\dfrac{29}{6}\times\dfrac{3}{2}=\dfrac{29}{4}[/tex] miles.
[tex]=6\dfrac{5}{4}[/tex] miles.
Hence, she can run [tex]6\dfrac54[/tex] mile sin 1 hour.
the zero of the quadratic polynomial x^2+99x+127 are a both positive b both negative c one +ve one-ve d both equal. please help
Step-by-step explanation:
By Descrates' Rule of Signs,
x² + 99x + 127 changes sign 0 times.
Hence it has 0 positive roots.
Since the discriminant b² - 4ac is also positive, there are 2 real distinct roots.
Hence both the roots are negative. (B)

A half marathon is around 13 miles. Brian can run about 6 1⁄3 miles per hour. If Brian keeps his pace, how long will it take him to run a half marathon?
Answer:
2.053 hours
Step-by-step explanation:
From the question,
A half marathon is around 13 miles. Brian can run about 6 1⁄3 miles per hour.
If Brian keeps his pace, how long will it take him to run a half marathon?
This is calculated as:
6 1/3 miles = 1 hour
13 miles = x hour
Cross Multiply
6 1/3 miles × x hour = 13 miles × 1 hour
x hour = 13 miles × 1 hour/6 1/3 miles
x hour = 13 ÷ 6 1/3 miles
x hour = 13 ÷ 19/3
x hour = 13 × 3/19
x hour = 39/19
x hour = 2.0526315789 hours
Approximately = 2.053 hours
It will take him 2.053 hours to run a half marathon.

what is the linear equation for this graph? (y=mx+b)
Answer:
y = -3x - 3
Step-by-step explanation:
the y-intercept is -3 as shown in the graph, so, b = -3
if you count, the rise is 3 and the run is -1, so the slope will be -3/1
-3/1 equals to -3
y = -3x - 3
Answer:
y = –3x – 3
Step-by-step explanation:
m = the slope which is 3/1, or 3. Since the line is going from the bottom right corner to the top left, it is a negative slope so –3.
b = the y-intercept which is –3.
So,
y = –3x – 3
