Determine the equation of the tangent to x− 3x +1 at the point (3,1)
9514 1404 393
Answer:
y = 3x -8
Step-by-step explanation:
We assume you want the tangent to the parabola y = x² -3x +1 at the given point. The slope is found using the derivative of the function at that point.
y' = 2x -3
At x=3, the slope is ...
y' = 2(3) -3 = 3
The equation of the line through point (3, 1) with a slope of 3 is ...
y -1 = 3(x -3) . . . . use the point-slope form of the equation for a line
y = 3x -9 +1 . . . . . eliminate parentheses, add 1
y = 3x -8
sarah has a coupon 25% off any item at the big fish store. If she buys an item reguarly marked $60, What is her sale price?
Answer:
$45
Step-by-step explanation:
60×0.75=45
Hope this helps
At the big fish store, Sarah has a coupon good for 25% off any purchase. She will pay $45 for a $60 item if she purchases it at a reduced price.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that Sarah has a coupon for 25% off any item at the big fish store. If she buys an item regularly marked $60,
Sale price =Original price - discount
Sale price = $60 - 25% of $60
Sale price = $60 - $ 15
Sale price = $45
Thus, at the big fish store, Sarah has a coupon good for 25% off any purchase. She will pay $45 for a $60 item if she purchases it at a reduced price.

1/4y+9=1/2
Answer:
y = -34
Step-by-step explanation:
Step 1
1/4 y + 9 = 1/2
1/4 + 9 - 9 = 1/2 - 9
1/4 y = -17/2
Step 2
4 * (1/4 y) = 4* (-17/2)
y = -34

Identify the function shown in this graph.
If r varies directly as t andr= -20 when t = 4, find r when t= -6.
Answer:
Step-by-step explanation:
t r = k/t Where k = constant of proportionality 132 = k/4 k = 4 x 132 k = 528 Formula r = 528/t Using formula r = 528/32 r = 16.5 Hope this helps :-) ...
The value of r should be considered as the 16.5 at the time when t = 4.
Calculation of the value of r:Since we know that
t r = k/t
here k = constant of proportionality
So,
132 = k/4
k = 4 x 132
k = 528
Now
r = 528/t
r = 528/32
r = 16.5
hence, The value of r should be considered as the 16.5 at the time when t = 4.

determine if the point (4,7) is a solution to the system of equations shown below. Justify your yes/no answer.
y=2x-1 and y=1/2x+5
Answer:
The point (4,7) is a solution to the system of equations.
Please also check the attached graph.
Step-by-step explanation:
Given the system of equations
[tex]y=2x-1[/tex]
[tex]y=\frac{1}{2}x+5[/tex]
Let us solve the system of equations using the elimination method
[tex]\begin{bmatrix}y=2x-1\\ y=\frac{1}{2}x+5\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-2x=-1\\ y-\frac{1}{2}x=5\end{bmatrix}[/tex]
subtracting the equations
[tex]y-\frac{1}{2}x=5[/tex]
[tex]-[/tex]
[tex]\underline{y-2x=-1}[/tex]
[tex]\frac{3}{2}x=6[/tex]
now solving [tex]\frac{3}{2}x=6[/tex] for x
[tex]\frac{3}{2}x=6[/tex]
Multiply both sides by 2
[tex]2\cdot \frac{3}{2}x=6\cdot \:2[/tex]
Simplify
[tex]3x=12[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{12}{3}[/tex]
Simplify
[tex]x=4[/tex]
For [tex]y-2x=-1[/tex] plug in x = 4
[tex]y-2\cdot \:4=-1[/tex]
[tex]y-8=-1[/tex]
Add 8 to both sides
[tex]y-8+8=-1+8[/tex]
Simplify
[tex]y=7[/tex]
Therefore, the solution to the system of equations is:
(x, y) = (4, 7)
Hence, the point (4,7) is a solution to the system of equations.

Answer:
33 ft²
Step-by-step explanation:
Each triangle's area is given by the formula ...
A = (1/2)bh
A = (1/2)(3 ft)(4 ft) = 6 ft²
The square base area is given by ...
A = s²
A = (3 ft)² = 9 ft²
__
The total area of the pyramid is the area of the base plus the area of four triangular faces.
Total Area = (9 ft²) + 4(6 ft²) = (9 +24) ft²
Total Area = 33 ft²

Jared consuela and Reggie have an ant farm Jared collected 25/100 of the ants from the ant farm consuela collected 6/10 of the ants what fraction of the ants did Jared and consuela collected together
Answer:
17/20
Step-by-step explanation:
[tex]\frac{25}{100} + \frac{6}{10}[/tex]
to solve this multiply both fractions by 100
(25 + 60) / 100 = 85/100
we need to find the lowest common multiple
Both the numerator and denominator can be divided by 5 = 17/20
The ratio of men to women working for a company is 5 to 6. If there are 198 employees total, how many women work for the company?
Answer: 110 Women !
Step-by-step explanation:
Call their numbers 4x to 5x.
Since there are a total of 198 people,
4x + 5x = 198
9x = 198
x = 22
so that there are
88 men and 110 women.

Toby is trying to show his teacher why the product of two rational numbers is another
rational number. His first steps are shown. Which is the best method Toby could use to
proceed?
L
B
Using the concept of rational numbers, it is found that the best method Toby could use is a multiplication of fractions, as the product of two fractions(two rational numbers) is always a fraction(rational number).
-------------
A rational number, no matter if an integer, a finite decimal or a repeating decimal can always be represented by a fraction.The product of two fractions will always result in a fraction, as the numerator of the multiplication is the multiplication of the numerator of the factors, and same for the denominator.Thus, since the product of two fractions is always a fraction, the product of two rational numbers is always a rational number.A similar problem is given at https://brainly.com/question/10814303

Q varies as e if q is 24 when e is 3 find q when e is 7
Answer:
q = 56
Step-by-step explanation:
Given that q varies as e, then the equation relating them is
q = ke ← k is the constant of variation
To find k use the condition q = 24 when e = 3 , then
24 = 3k ( divide both sides by 3 )
8 = k
q = 8e ← equation of variation
When e = 7 , then
q = 8 × 7 = 56
