Given equation,
89 (54x − 36) + 2 = -34( −40 + 16x) + 90x
using PEMDAS
solving Parentheses first,
89(54x) - 36(89) + 2 = -34(-40) + 16x(-34) +90x
4806x - 3204 +2 = -1360 - 544x + 90x
4806x + 544x - 90x = -1360 + 3204 -2

Which statement is true about the points shown on the number line?
Option B is a correct representation of the given number line, -3.8 < 1.5, and is located to the left of 1.5.
What is a number line?A number line is a visual depiction of numbers on a straight line drawn either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on them when they are written down on a number line. A number line is thought to begin at zero (0). Left of zero, there are only negative numbers, and right of zero, there are only positive numbers.
Given a number line and two points marked on it,
-3.8 and 1.5
we find from the number line that -3.8 lie left to 1.5,
and the negative numbers are always less than the positive numbers,
so -3.8 is less than 1.5,
-3.8 < 1.5, and lie left to 1.5.
Hence, option B is correct.

if line ST is congruent to line SV, TU=w+10, and UV=2w what is the value of w
If line ST exists congruent to line SV, TU=w+10, and UV=2w then the value of w exists 10.
What does congruent line mean?If two line segments are congruent to one another and are the same length, then they are said to be equal. The angles they make with an axis or location in the plane may or may not be the same.
Congruence between two line segments indicates that their lengths are equal. Two shapes are said to be congruent if they correspond throughout if you take one up and place it on the other (they will match up perfectly and you will not be able to see the one on the bottom).
If line ST exists congruent to line SV, TU = w + 10, and UV = 2w.
TU = UV
substitute the values of TU and UV in the above equation, we get
w + 10 = 2w
simplifying the equation, we get
w = 2w - 10
-w = -10
Divide both sides by -1
[tex]$\frac{-w}{-1}=\frac{-10}{-1}$$[/tex]
w = 10

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse.
This is a question about the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two legs is equal to the square of the length of the hypotenuse.
We can call the distance from the bottom of the ladder to the base of the building as x, and the distance between the ladder base and the building as the ladder's height = h.
By using Pythagorean theorem: x^2 + h^2 = 72^2 , the distance from the bottom of the ladder to the base of the building is x = √(72^2 - 60^2) = √(5184 - 3600) = √1584 = 39.6 ft.

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Complete the function that models the distance they drive as a function of time. Then complete a reasonable domain for this situation.
function notation in slope-intercept form: f(x) =
reasonable domain:
≤ x ≤
The function that models the distance they drive as a function of time is; 120 = 50t + 20
The required domain is;. 0 ≤ t ≤2
How to find the domain of the function?The formula for calculating distance travelled is expressed as:
Distance = Speed × time
The parameters are;
Total distance = 120 miles
Distance already travelled = 20miles
They are driving at a constant rate of 50mi/hr. Thus, the distance travelled at the time "t", during this period will be 50t.
The equation of a line in slope intercept form is;
y = mx + c
Thus,
The required function that models the distance is expressed as;
120 = 50t + 20
To find the domain, we need to get the value of t as shown;
120 = 20 + 50t
120 - 20 = 50t
100 = 50t
t = 100/50
t = 2sec

The points (5, 7) and (3, 3) fall on a particular line. What is its equation in slope-intercept form?
Answer:
y = 2x - 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 7 ) and (x₂, y₂ ) = (3, 3 )
m = [tex]\frac{3-7}{3-5}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2 , then
y = 2x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (3, 3 ) , then
3 = 2(3) + c = 6 + c ( subtract 6 from both sides )
- 3 = c
y = 2x - 3 ← equation of line

(a) A company manufactures 15-inch laptops and 17-inch laptops. It takes 3 hours to manufacture a 15-inch laptop and 5 hours to manufacture a 17-inch laptop. Each 15-inch laptop has 256 GB of memory and each 17-inch laptop has 512 GB of memory. The company has 480 hours available and parts for 43,520 GB of memory. The company makes a profit of $2000 on each 15-inch laptop and $3000 on each 17-inch laptop.
Answer:
We can start by using the information provided to calculate how many laptops of each size the company can manufacture within the 480 hours available:
15-inch laptops: 480 hours / 3 hours per laptop = 160 laptops
17-inch laptops: 480 hours / 5 hours per laptop = 96 laptops
With the 480 hours available and the number of laptops that can be manufactured, we can calculate the total amount of memory that can be used:
15-inch laptops: 160 laptops x 256 GB per laptop = 40,960 GB
17-inch laptops: 96 laptops x 512 GB per laptop = 49,152 GB
Since the company has 43,520 GB of memory available, it can manufacture:
15-inch laptops: 43,520 GB / 256 GB per laptop = 170 laptops
17-inch laptops: 43,520 GB / 512 GB per laptop = 85 laptops
The company can manufacture 170 15-inch laptops and 85 17-inch laptops.
Now, we can calculate the profit that the company can make:
15-inch laptops: 170 laptops x $2000 per laptop = $340,000
17-inch laptops: 85 laptops x $3000 per laptop = $255,000
So, the company can make a total profit of $595,000 from the 170 15-inch laptops and 85 17-inch laptops.
The company can manufacture 170 15-inch laptops and 85 17-inch laptops, and make a total profit of $595,000.

of that is spent on educational programs for zookeepers. What is the cost for
zookeeper education?
So the cost for zookeeper education is $13,932.5
What is a fraction?
A fraction represents a part of a number or any number of equal parts. There is a fraction, containing numerator(upper value) and denominator(lower value).
To calculate the cost for zookeeper education, we need to multiply the total budget for animal care by 1/6.
83,595 x 1/6 = 13,932.5
So the cost for zookeeper education is $13,932.5.
Explanation:
1/6 of the budget, which is expressed as a fraction, is the same as dividing the budget by 6.
So we can use the formula 83,595 / 6 = 13,932.5, the result is the cost for zookeeper education.

What is the point of intersection?
When the lines intersect, the point of intersection is the only point that the two graphs have in common, so the coordinates of that point are the solution for the two variables used in the equations.
The terminal ray of an angle in standard position passes through the point (x,y) in the coordinate plane, where x and y are the coordinates of the point of intersection of the terminal ray with the x-axis and y-axis respectively.
Given that the terminal ray of angle A passes through the point (-6,4)
The coordinates of the point of intersection of the terminal ray with the x-axis are (-6,0) and y-axis are (0,4)
Using the distance formula
The distance from the origin to the point (-6,4) is √((-6-0)^2 + (4-0)^2) = √(6^2 + 4^2) = √(36 + 16) = √(52) = 2*√(13)
Now we can use these coordinates to find the value of sec(A) which is defined as sec(A) = 1/cos(A) = distance of point from x-axis/distance from origin.
sec(A) = 4/2*√(13) = 2/√(13)
hence, the value of sec(A) is 2/√(13) in simplified form, in the standard position.
