Answer:
about 2.1
Step-by-step explanation:
The slope of the secant line is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (121/100 -1)/(11/10 -1) = (21/100)/(1/10) = 2.1
The slope of the tangent is about 2.1.
_____
Additional comment
We can refine our estimate by choosing a secant line between the points (9/10, 81/100) and (11/10, 121/100). That is, points either side of x=1.
That slope is ...
(121/100 -81/100)/(11/10 -9/10) = (40/100)/(2/10) = 2.0
We expect the slope of the tangent at x=1 to be exactly 2.0.

2y=-x+9
3×-6y=-15 whats the solution to the system
Answer:
Step-by-step explanation:
2y = -x +9
3x - 6y = -15
The solution is the value of x and y that will make the two equations true in the same time.
3x-6y = -15; divide both sides by 3
x-2y = -5; substitute 2y for -x+9 because the first equation tell us they are equal
x-(-x+9) = -5; open parenthesis
x+x-9 = -5 ; add 9 to both sides and combine like terms
2x = -5 +9; 2x = 4; divide both sides by 2
x= 2
Substitute x for 2
2y = -x+9 ; 2y = -2 +9 ; 2y = 7; y = 7/2 = 3.5
Solution is (2, 3.5)
Answer:
(2, 7/2)

a. $35.42
b. $118.58
C. $177.00
d. $189.42
Answer:
D. 189.42
Step-by-step explanation:
The amount that will be withheld from his paycheck for income tax in all is d. $189.42.
Using this formula
Amount withheld=State income tax+( State income tax× Percentage of federal income tax)
Where:
State income tax=$154.00Percentage of federal income tax=23%Let plug in the formula
Amount withheld=$154.00+($154,00×23%)
Amount withheld=$154.00+$35.42
Amount withheld=$189.42
Inconclusion the amount that will be withheld from his paycheck for income tax in all is d. $189.42.

Answer:
5/16 Got a C
Step-by-step explanation:
A = 1/4 x 32
B = (32 - A)/2
D = 2
A = 8
B = (32 - 8)/2
B = 24/2
B = 12
D = 2
8 + 12 + 2 = 22

Berry delicious is a popular shop that sells the shop used 60% more strawberries than the previous year when it used 3,090 kilograms how many strawberries did berry delicious use this year
Answer:
4,944 kg of strawberries
Step-by-step explanation:
In order to know the amount of strawberries Berry Delicious used this year, you have to know how much is 60% of 3,090 kg of strawberries. You can solve this by multiplying 3,090 by 60%.
Let's solve.
3,090 kg x 60% (0.60) = 1,854 kgNext, we have to add 1,854 kg to 3,090 kg.
3,090 kg + 1,854 kg = 4,944 kg of strawberriesTherefore, Berry Delicious used 4,944 kg of strawberries this year. This is 1,854 kg more than last year's.

Distributive property is basically just multiplying the outside number with the things that are in the parentheses. so 7*p is 7p, 7*q is 7q, and 7*9 is 63, so that makes your answer 7p+7q+63
A triangle has two 90° angles and a side 12 centimeters in length.
Select True or False for each statement about this type of triangle.
Answer:
False for the first one
true for the second
true for the last
Step-by-step explanation:
The triangle with 2 angles as 90° is not possible and the statement is false
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ∠ABC
Now , the measures of the angles of the triangle are
A triangle has two 90° angles and a side 12 centimeters in length
So , ∠ABC = ∠BAC = 90°
And , For a Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
Therefore , a triangle cannot be formed with 2 angles as 90°
Hence , the statement is False

4. In the diagram, LW is parallel to ST. RL = 6 centimeters, LS = 3
centimeters, and WT = 4 centimeters.
The solution is, The value of x is 8. so, the correct answer is option C.) 8.
Here, we have,
from the given diagram, we get,
In the diagram, LW is parallel to ST.
RL = 6 centimeters, LS = 3 centimeters, and WT = 4 centimeters.
as, we know that,
if, LW is parallel to ST , by property of triangle,
we get,
LW divides RT & RS proportionally.
i.e. RW: WT = RL : LS
now, here, RW = x
so, we have,
x: 4 = 6 : 3
or, x = 6 *4 / 3
or, x = 8
Hence, The value of x is 8.

Match the graph with the correct equation.
Answer:
y = 1.2x + 1.5
Step-by-step explanation:
Formula: y = mx + b
m = slope
b = y-intercept
The y-intercept is at "1.5"
slope = y/x or rise over run
r/r = 6/5 = 1.2
Slope is 1.2
Equation form....
y = 1.2x + 1.5
And the slope is positive since the line is increasing
