Solve for y 8x-7y=23 (fill all of the boxes)
Answer:
i think this is the correct answer
Step-by-step explanation:
Simplifying
8x + -7y = 23
Solving
8x + -7y = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
8x + -7y + 7y = 23 + 7y
Combine like terms: -7y + 7y = 0
8x + 0 = 23 + 7y
8x = 23 + 7y
Divide each side by '8'.
x = 2.875 + 0.875y
Simplifying
x = 2.875 + 0.875y

Step-by-step explanation:
E2023
Answer:
see attached diagram
market = (3, 8)
Step-by-step explanation:
Park = (2, 5)
Find the number 2 on the x-axis, then count up 5 units
Park = (2, 5)
x-coordinate: 1 unit to the right = 2 + 1 = 3
y-coordinate: 3 units up = 5 + 3 = 8
Therefore, market = (3, 8)

Ross says a $125.95 skateboard at 40% off is cheaper than a $169.95 skateboard at 60% off. Is he correct?
Answer:
Ross isn't right.
Step-by-step explanation:
Skateboard $125.95 at 40% off is $75.57
How I got the number:
125.95/100 = 1.2595
1.2595 x 40 = 50.38
125.95 - 50.38 = 75.57
Skateboard $169.95 at 60% off is $67.98
169.95/100 = 1.6995
1.6995 x 60 = 101.97
169.95 - 101.97 = 67.98
Therefore the skateboard that is 60% off is cheaper.

Max is mountain hiking at a constant rate. This equation y = 10x 30 can be used to represent this situation, where y is Max's elevation in meters and x is the number of hours Max has been hiking. Which statement best describes Max's elevation, given this equation?.
Answer:
D.) Max started at a height of 30 meters and is ascending at 10 meters per hour.
Step-by-step explanation:
This equation y = 10x + 30 can be used to represent this situation, where y is Max's elevation in meters and x is the number of hours Max has been hiking
Max started at the height of 30 meters and is ascending at a rate of 10 meters per hour. Then the correct option is A.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The equation is y = 10x + 30.
Where y is Max's elevation in meters and x is the number of hours.
Max has been hiking.
From the equation, we can conclude.
Max is ascending at a rate of 10 meters per hour.
Max is at the height of 30 meters at the starting.
Thus, option A is correct.

Find the area of the parallelogram.
Answer:
3484 [tex]ft^{2}[/tex]Step-by-step explanation:
Given,
The figure is of a parallelogram
Height (h) of the parallelogram = 52 ft.
Since,
In a parallelogram opposite sides are equal so,
Corresponding base to the height of the parallelogram is = 67 ft.
Therefore,
Area of the given parallelogram
= base × height
[On substituting their values]= 67 ft. × 52 ft.
[On multiplying]= 3484 [tex]ft^{2}[/tex]
Hence,
The required area of the parallelogram is 3484 [tex]ft^{2}[/tex] (Ans)
The angle of elevation of the sun is 39° from the ground. A business building downtown casts a shadow that is 89 m long. How tall is the building?
[tex]\tan 39 \textdegree = \displaystyle \frac{h}{89}\\\\89\tan 39 \textdegree = h\\\\h = 72[/tex]Answer:
72 m
Step-by-step explanation:
Hi there!
Using the given information, we can construct a diagram. Please see the attached image.
We need to solve for the height of the building, or the length of the side opposite the angle that measures 39°. Given the only other piece of information is the length of its adjacent side, which is 89 m, we can use the tangent ratio to solve for the height:
[tex]\tan \theta = \displaystyle \frac{opposite}{adjacent}[/tex]
Plug in the given values:
tan 39° = h/89
89 tan 39° = h
h = 72
Therefore, the height of the building is 72 m.

Paul opens a savings account with $350. He saves $150 per month. Assume that he does not withdraw
money or make any additional deposits.
a. Write a linear model that represents the total amount of money Paul deposits into his account after m months.
b. After how many months will Paul have $2,000?
Answer:
350+150m=total money
11 months
Step-by-step explanation:
you just put in the number of months that have passed in for m and solve for total money.
After how many months will Paul have $2,000?
350+150m=2000
350-350+150m=2000-350
150m=1650
150m/150=1650/150

2 2/3 lbs of rice cost $5.52. What is the cost of 1lb
Answer: I'm not fully sure but I think its 2.07
Answer:
$2.07 per pound
Step-by-step explanation:
we can rewrite 2 2/3 as 8/3
now we can create a proportion from cost to pounds of rice
5.52 is to 8/3 pounds as 'c' is to 1:
(5.52 ÷ 8/3) = c/1
cross-multiply to get:
8/3c = 5.52
multiply each side by 3/8 to get:
c = 5.52(3/8)
c = 2.07
Carlos designs the skateboard ramp shown in the diagram, 132in h? 22 degrees Enter the height of the ramp (h), in inches, Round your answer to the nearest whole inch.
The height of the ramp is 49.45in
Data;
Length of the skateboard = 132inAngle between the height and skateboard = 22 degreesheight of the skateboard rampTrigonometric RatioTo solve this problem, we can use trigonometric ratio SOHCAHTOA
Since we have the value of the angle and length of the ramp, this can be illustrated as hypotenuse and angle between the hypotenuse and opposite of the right-angle triangle.
From the information above, we have angle and hypothenuse but we need to solve for the opposite of the right-angle triangle. The sine angle can solve this problem.
[tex]sin \theta = \frac{opposite}{hypothenuse} \\sin 22 = \frac{x}{132} \\x = 132 sin 22\\x = 49.45 in[/tex]

Answer:
Yes it is a function. It passes the vertical line test. In other words, it is impossible to draw a single vertical line through more than one point on the V shaped graph. Any input leads to exactly one output.
The domain is the set of all real numbers. This is because we can plug in any x value leading to some specific y value. There are no holes or gaps or jumps to indicate we must restrict any given x value. The domain would not be the set of whole numbers only because values between the whole numbers (eg: decimal values like x = 2.75) work just fine.
The range is the set of y values such that y is either 0 or larger than 0. In short, the range is . Notice how any point on the V shaped graph has a y coordinate that is either 0 or larger than 0. It is impossible to get a y value that is negative.

Write an equation in slope-intercept form for the line with slope -6 and y-intercept 7. Then graph the line.
Answer:
y = -6x + 7
Step-by-step explanation:
Slope-intercept form: y = mx + b
where:
m is the slopeb is the y-intercept (when x = 0)Given: a line with a slope of -6, and y-intercept of 7
Equation: y = -6x + 7
y-intercept: (0, 7)Randomly select x-values that will help you graph the equation:
when x = -2:
y = -6(-2) + 7 [multiply]
y = 12 + 7 [add]
y = 19
coordinate: (-2, 19)
when x = 1:
y = -6(1) + 7 [multiply]
y = -6 + 7 [add]
y = 1
coordinate: (1, 1)
when x = 2:
y = -6(2) + 7 [multiply]
y = -12 + 7 [add]
y = -5
coordinate: (2, -5)
These coordinates fall on the line for the linear equation. Graph them on a coordinate plane, and they should give you the line for the equation.

Answer:
10.3 cm
Step-by-step explanation:
There are a few ways to do this.
1)Using the law of cosines, you have ...
b² = a² +c² -2ac·cos(B)
b² = 11² +11² -2(11)(11)·cos(56°) = 106.67
b = √106.675 ≈ 10.3
AC = 10.3 cm
__
2)Using trig functions. When you draw an altitude in this isosceles triangle from B to AC, it divides AC in half, and it divides angle B in half. The sine relation can help here:
Sin = Opposite/Adjacent
sin(56°/2) = (AC/2)/(11 cm)
AC = (22 cm)sin(28°) ≈ 10.3 cm
__
3)Using a triangle solver, you can find the value of AC to be about 10.3 cm. Triangle solvers are available as apps and on the web. Your graphing calculator may have one. See attached for the results from a nice solver available on the web. Units are cm.
