HELP!!!! how many solutions does this linear system have?
Answer:
Yes. Your answer is correct. There is only one solution:. (1, -4).
Step-by-step explanation:
If you plug in 1 for x and -4 for y both sides of the equation are equal to each other. (Because the points are (x, y))
But any other answer is not right because when you plug in the answer the sides don't equal each other.

Answer:

Step-by-step explanation:
To find the relative maximum of a function the double derivative should be less than zero at the stationary point. For that we need to find the stationary value/values of the function so here goes,
[tex]f(x)=-x^3+6x^2-9x-1\\f'(x)=-3x^2+12x-9\\\\For\ stationary\ point\ f'(x)\ equals\ zero\\\\0=-3x^2+12x-9\\3x^2-12x+9=0\\x^2-4x+3=0\\\\x^2-3x-x+3=0\\x(x-3)-1(x-3)=0\\(x-3)(x-1)=0\\x=3\ ,\ x=1[/tex]
Now since we have two values of x at which the function is stationary we need to test them both for that we need to take the double derivative so here goes,
[tex]f'(x)=-3x^2+12x-9\\f''(x)=-6x+12\\now\ put\ x = 1\\f''(1)=-6(1)+12\\f''(1)=-6+12=6\\since\ f''(1)>0[/tex]
The point x = 1 is a relative minimum
But we need the relative maximum so lets try out x = 3
[tex]f''(x)=-6x+12\\f''(3)=-6(3)+12\\f''(3)=-18+12=-6[/tex]
[tex]since\ f''(3)<0[/tex]
The point x = 3 is the relative maximum because for relative maximum the double derivative should be negative or less than 0 in this case its true so the last option is your answer

A. Explain why ABC and ADBE
are similar
B. What is the height of the building?
Step-by-step explanation:
This figure is not the best, but I'll try my best here
Since BC is parallel to BE (BC is part of BE) and BA is part of BD, two sides are parallel, making two angles congruent and the triangles therefore similar.
Since BA correlates to BD (they are parallel), we can use the knowledge that BA is 7 and BD is 42 to find the scaling factor to be 42/7 =6 from ABC to DBE. Since BC correlates to BE, BC = 10, and the scaling factor is 6, BC*6=BE= 60 = height

1F hX)=(fog)(x) and h(x)=5(x + 1)³ Find one possibility For f(x) and g(x)
Answer:
f(x) is 5x³ and g(x) is x+1
Step-by-step explanation:
Given the composite function:
h(x) = f(g(x)) = 5(x + 1)³
The function and be splitted into 5x³ and x+1 where f(x) = 5x³ and g(x) = x+1
Check:
f(g(x)) = f(x+1)

8.3 + 5y = -7
- 7x + y = -4
Answer:
Multiplying the first equation by 1 and the second equation by 5 to eliminate the y variable .
x= 0.3
y= -1.9
Step-by-step explanation:
8.3x + 5y = -7 ----------i
- 7x + y = -4 -----------ii
Multiply the first equation by 1 and the second equation by 5 to eliminate the y variable as below;
[8.3x + 5y = -7 ]1
[- 7x + y = -4]5
8.3x + 5y = -7
-35 x + 5y = -20
perform subtraction to eliminate y as
8.3x --35x = -7--20
43.3 x = 13
x= 13/43.3
x= 0.3
Using equation ii ;
-7x + y = -4
-7 * 13/43.3 + y = -4
-91/43.3 + y = -4
y= -4 + 91/43.3
y= -4 + 2.1
y= -1.9

Cherries cost $4/lb. Grapes cost $2.50/lb. You can spend no more than $15 on fruit, and you need at least 5 lb in
all. Create a graph showing the amount of each fruit you can buy.
i need a picture of a graph
Answer:
Let's define the variables:
x = number of Cherrie pounds you buy
y = number of Grape pounds you buy.
The total cost of buying that will be:
x*$4 + y*$2.50
And this must be no more than $15, then we have the inequality:
x*$4 + y*$2.50 ≤ $15
And we also know that you need at least 5 pounds in total, then we will have:
x + y ≥ 5
We have the set of inequalities:
x + y ≥ 5
x*$4 + y*$2.50 ≤ $15
To graph them, a easy way is to write them as lines, and just graph the lines:
y ≥ 5 - x
y ≤ ($15 - x*$4)/$2.50
in the first inequality, we have the symbol ≥, this means that we will have a solid line and we must shade above the line.
In the second inequality, we have the symbol ≤, this means that we will have a solid line and we must shade below the line.
And we also must include the conditions:
x ≥ 0
y ≥ 0
Because you can only buy positive numbers of fruit.
This will restrict us to the first quadrant only
Then the graph will be the one shown below.
Where the solutions are the ones in the double shaded region in the first quadrant.
The inequalities that represent the given data are [tex]\rm y \leq \dfrac{15-4x}{2.5}[/tex] and [tex]\rm y\geq 5-x[/tex] and the graph of these inequalities is attached below.
Given :
Cherries cost $4/lb. Grapes cost $2.50/lb. You can spend no more than $15 on fruit, and you need at least 5 lb in all.The following steps can be used in order to determine the graph showing the amount of each fruit you can buy:
Step 1 - Let 'x' be the total amount of cherries in pounds and let 'y' be the total amount of grapes in pounds.
Step 2 - The inequality that represents the total amount of fruits you can buy is given below:
[tex]\rm 4x+2.5y\leq 15[/tex]
[tex]\rm y \leq \dfrac{15-4x}{2.5}[/tex]
Step 3 - The inequality that represents the total amount of fruits you need to buy:
[tex]\rm x+y\geq 5[/tex]
[tex]\rm y\geq 5-x[/tex]
Step 4 - The graph that represents the inequalities evaluated in the above steps is attached below.

Dawn earned $97.50 for 10 hours of work. Amy earned 120 in 12 hours of work how much did each person earn per hour
Answer:
Amount earned in 1 hour [tex]=\$9.750[/tex]

Total amount earned by Dawn = $97.50
Dawn earned $97.50 for 10 hours of work
Amount earned in 1 hour [tex]=\frac{97.50}{10}=\$9.750[/tex]

Solve for x. 7x−9 11
Enter your answer, including the inequality symbol, in the boxes.
x_____or x ______
Answer:
x<20/7
Step-by-step explanation:
The expression is not well written. Fine the correct expression below
Given the expression 7x−9<11
Add 9 to both sides of the expression
7x-9+9<11+9
7x < 20
Divide both sides by 7
7x/7 = 20/7
x < 20/7
Hence the required solution is x<20/7
Which equation, when graphed with the given equation, will form a system that has no solution?
y = 3x+6
y=-3(x+6)
y=-3(x-2)
y = 3(x-2)
Answer:
Y=-3(x+6)
Step-by-step explanation:
Did this on edge2020
Answer:
y = -3(x + 6) and y = -3(x - 2)
Step-by-step explanation:
A system that has no solutions means that the lines do not intersect at any point meaning the lines are parallel to each other, and for lines to be parallel to each other the slope of the lines should be equal since parallel lines have same slope.
So the equation of the line in the graph is y = -3x + 6
and the equation when graphed will form a system that has no solution is
y = -3(x + 6) and y = -3(x - 2)
both have same slope to the slope of the line graphed in the figure that is -3
