Answer:
The point where all three lines meet is (8, 11)
Step-by-step explanation:
The given functions are;
f(x) = x²⁽ˣ ⁻ ⁵⁾ + 3
g(x) = 2·x - 5
h(x) = 8/x + 10
Equating the simpler functions g(x) to h(x) to find the points of the same value gives;
2·x - 5 = 8/x + 10
2·x - 15 = 8/x
2·x² - 15·x = 8
2·x² - 15·x - 8 = 0
With the aid of an online application, we have;
(2·x + 1)(x - 8) = 0
x = -1/2, or x = 8
The y-values at the point of intersection, is given as follows;
g(x) = 2·x - 5 = 2×(-1/2) - 5 = -6 or g(x) = 2·x - 5 = 2×(8) - 5 = 11
The points where g(x) and h(x) meet are (-1/2, -6) and (8, 11)
To check where the point of intersection of the two functions g(x) ang h(x) meet f(x), we have;
At x = -1/2, f(x) = [tex]2^{(0.5 - 5)} + 3[/tex] = 3.0442
At x = -1/2, f(x) = 2⁽⁸⁻⁵⁾ + 3 = 8 + 3 = 11
Therefore, the point where all three lines meet = (8, 11).
Find the sum of QR
4x+33
Answer:
Step-by-step explanation:
Simplifying
4x + 5 = 33
Reorder the terms:
5 + 4x = 33
Solving
5 + 4x = 33
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + 4x = 33 + -5
Combine like terms: 5 + -5 = 0
0 + 4x = 33 + -5
4x = 33 + -5
Combine like terms: 33 + -5 = 28
4x = 28
Divide each side by '4'.
x = 7

Tyler swims at a constant speed, 6 meters every 4 seconds. How long does it take him to swim 114 meters?
Answer:
91.2 seconds
:)
Answer:
76 seconds (1:16 one hour and 16 minutes)
Step-by-step explanation:
You take the distance that he has to travel (114m) and you divide it by the distance you're given that he is moving at every time (6m). this gives us 19. Then you take that and multiply it by how many seconds it takes him to move the given 6m (4s), which gives us an answer of 76 seconds

Step-by-step explanation:
Answer:
No Omar does not have to put the blanket
Step-by-step explanation:
The answer is No ,because since Omar only covers the plant when its below 0 , And when the temperature is 5 degrees Celsius at 4:00 pm and the temperature is predicted to decrease 0.5 degrees Celsius every two hours until 4:00 am. So 6 times 0.5 =3 so 5 - 3 = 2

WILL GIVE BRAINLIEST The knitting club sold 40 scarves and hats at a winter festival and made $700 from
the sales. They charged $18 for each scarf and $14 for each hat.
If x represents the number of scarves sold and y represents the number of hats
sold, how many scarves and hats did the knitting club sell at the winter festival?
I NEED HOW MANY SCARVES AND HATS WERE SOLD NOT THE SOLUTION
Answer:
s+h=40 and 18s+14h=700
Step-by-step explanation:
lets say
s= number of scarves sold
and
h=number of hats sold
since the total of hats/scarves equals 40 then that means that scarves+hats sold equals 40 so
s+h=40
the second constraint it found similarly,
scarves and hats are being sold for 18$ and 14$ respectively and together they need to equal 700$ so you plug it into a similar equal as before
18s+14h=700

In isosceles triangle ABC the segment BD is the median to base line AC. Find BD if the perimeter of the triangle is 50m and the perimeter of ABD is 40 m
Answer:
BD = 15 m
Step-by-step explanation:
Mathematically, we can find the perimeter of a triangle by adding all of the sides
Mathematically, the line from the top vertix of an isosceles triangle is perpendicular to the base line
So what this mean is that it splits the base line into 2 equal parts
So, in this case, since AC is base;
AD = CD
Please check the attachment for diagrammatic representation
So from the diagram;
25-x + x + BD = 40
25 + BD = 40
BD = 40-25
BD = 15 m

Find the slope of the line without graphing using the 2 points below.
(3 , -10) & (4 , -21)
m = _______
Answer: m=-11
Step-by-step explanation:
To find the slope of the line, you want to use formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Since we are given two points, we can directly plug them in and solve.
[tex]m=\frac{-21-(-10)}{4-3} =\frac{-11}{1} =-11[/tex]
Now, we know that the slope is -11.

Step-by-step explanation:
1. A basketball player made 12 out of 15 free throws she attempted. She wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85% (a) Write an equation to represent this situation. (b) Solve the equation. How many consecutive free throws would she have to make to raise her percent to 85%?
Answer:
She would need to make 5 consecutive free successful throws
Step-by-step explanation:
Equations
A basketball player wants to improve his percent of successful throws to 85%.
She currently has made 12 out of 15 free throws, which gives a success percentage of 12/15*100=80%
So, she needs a number of free consecutive free throws to increase that number to the desired target.
The percentage of success can be calculated as:
[tex]\displaystyle P=\frac{\text{successful throws}}{\text{total throws}}*100[/tex]
Let's assume x is the number of required consecutive successful throws. Since she has already thrown 15 times, out of which has had 12 successful throws, now she will have 15+x total throws and 12+x successes, thus the new percentage is:
[tex]\displaystyle P=\frac{12+x}{15+x}*100[/tex]
And this percentage must be equal to 85%, thus:
[tex]\displaystyle \frac{12+x}{15+x}*100=85[/tex]
a) The equation to represent the situation is:
[tex]\mathbf{\displaystyle \frac{12+x}{15+x}*100=85}[/tex]
b) Let's solve it.
Multiply by 15+x:
[tex]\displaystyle (12+x)*100=85(15+x)[/tex]
Dividing by 5:
[tex]\displaystyle (12+x)*20=17(15+x)[/tex]
Operating:
[tex]\displaystyle 240+20x=255+17x[/tex]
Subtracting 17x and 240:
[tex]\displaystyle 20x-17x=255-240[/tex]
Simplifying:
[tex]\displaystyle 3x=15[/tex]
Dividing by 3:
x = 5
She would need to make 5 consecutive free successful throws
The number of throws is an illustration of proportions.
The number of free throws to raise her percent to 85% is 5
(a) The equation
The proportion is given as: 12 out of 15.
Let the number of throws be n.
So, the proportion would be:
[tex]\mathbf{Proportion = \frac{12 + n}{15 + n}}[/tex]
To make 85% success, then the proportion must equal 85%.
So, we have:
[tex]\mathbf{\frac{12 + n}{15 + n} = 85\%}[/tex]
(b) The solution to the equation
In (a), we have:
[tex]\mathbf{\frac{12 + n}{15 + n} = 85\%}[/tex]
Express 85% as decimal
[tex]\mathbf{\frac{12 + n}{15 + n} = 0.85}[/tex]
Cross multiply
[tex]\mathbf{12 + n = 0.85(15 + n)}[/tex]
[tex]\mathbf{12 + n = 12.75 + 0.85n}[/tex]
Collect like terms
[tex]\mathbf{n -0.85n= 12.75 -12 }[/tex]
[tex]\mathbf{0.15n= 0.75}[/tex]
Divide both sides by 0.15
[tex]\mathbf{n= 5}[/tex]
Hence, the number of free throws to raise her percent to 85% is 5

Quick!!
Answer:
-12x - 2 < -62
-12x - 2 > 34
Step-by-step explanation:
1. Start with
x > 5
Multiply both sides by -12.
-12x < -60
Subtract 2 from both sides.
-12x - 2 < -62
2. Start with
x < -3
Multiply both sides by -12.
-12x > 36
Subtract 2 from both sides.
-12x - 2 > 34
Answer:
-12x - 2 < -62
-12x - 2 > 34
