y= -3x + 1 and y= x - 3
Answer:
x= 1
y= -2
Step-by-step explanation:
equation (1): y= -3x+1
equation (2): y=x-3
solve the system of equations by substitution:
step1: sub ( x-3 ) for y in equation 1:
y = -3x+1
x-3 = -3x+1
step2: simplify the equation to get x:
(add 3 for both sides)
x = -3x+4
(add 3x for both sides)
4x = 4
(divide 4 from both sides)
x = 1
step3: sub the value of x (x=1) in equation 2:
y = x-3
y = 1-3
step4: solve the equation to get y:
y = -2

$2,016. The meal price per guest is $25. How many guests, x, can Margaret invite to the reception and stay under budget?
Select the number line that includes the largest number of guests Margaret can invite without exceeding her budget.
Answer:
I'm pretty sure it's C.
Step-by-step explanation:
4,991 - 2,016 is 2975 for the amount of money she has left over after what she spent already. 2975 divided by 25 is 119 for the amount of guests she can serve.

15 lb ≈ ? kg
Answer:
6.82 kg
Step-by-step explanation:
set up a proportion based on 2.2 lbs in 1 kg
2.2/1 = 15/x
cross-multiply:
2.2x = 15
x = 6.82
The value of 15 lb in kg is 6.81 kg.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We know that;
⇒ 1 lb = 0.454 kg
Hence, We get;
⇒ 1 lb = 0.454 kg
⇒ 15 lb = 15 × 0.454 kg
= 6.81 kg
Thus, We get;
⇒ 15 lb = 6.81 kg

Write the equation of the line that goes through (9,-4) and is perpendicular to the line
y = -3x – 8
Answer: y = (1/3)*x - 7
Step-by-step explanation:
When we have a line:
y = a*x + b
A perpendicular line to this one needs to have a slope s equal to:
s = -(1/a)
Then any line written as:
y = -(1/a)*x + c
is perpendicular to the lines of the form "y = a*x + b"
Then if we have the line:
y = -3*x - 8
The family of perpendicular lines to this one is:
y = -(1/-3)*x + c
y = (1/3)*x + c
where c can be any real number.
Now we also want that this line passes through the point (9, -4)
Then we need to replace x by 9, and y by -4
-4 = (1/3)*9 + c
Now we can solve this for c.
-4 = 9/3 + c
-4 = 3 + c
-4 - 3 = c
-7 = c
Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:
y = (1/3)*x - 7

Step-by-step explanation:
The value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.
What is Expression?An expression is combination of variables, numbers and operators.
1. The given equation is x /45 = 3
Now value of x is 45×3
x=135
3. The expression is −5.8 + (−2.5)
−5.8 −2.5
The value of expression is -8.3
4.To find the sale price after a 20% discount, we need to subtract 20% of the original price from the original price:
20% of $399 = (20/100) x $399 = $79.80
Sale price = $399 - $79.80 = $319.20
Therefore, the sale price is $319.20.
5. The side length of cube is 5 cm
Volume = 5³
=125 cubic centimeter
6. y = 8/ x equation represents a proportional relationship
7. 5 ft² is area of the wall will the game board cover
9. The given expression is 5 /8 x 4 /5
20/40
1/2
Hence, the value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.

Answer:
a) The length of segment AC is approximately 5.83 centimeters.
b) The angle ACD is approximately 34.5º.
Step-by-step explanation:
a) Since [tex]AB \perp BC[/tex], the length of segment [tex]AC[/tex] is determined by Pythagorean Theorem, that is:
[tex]AC = \sqrt{(5\,cm)^{2}+(3\,cm)^{2}}[/tex]
[tex]AC \approx 5.831\,cm[/tex]
The length of segment AC is approximately 5.831 centimeters.
b) Since [tex]AB \perp BC \perp AD[/tex], the length of segment [tex]AD[/tex] is determined by this Pythagorean identity:
[tex]AD = \sqrt{(3\,cm)^{2}+(5\,cm)^{2}+(4\,cm)^{2}}[/tex]
[tex]AD \approx 7.071\,cm[/tex]
The angle ACD is determined by the following trigonometric expression:
[tex]\cos C = \frac{AC}{CD}[/tex]
[tex]\cos C = \frac{5.831\,cm}{7.071\,cm}[/tex]
[tex]\cos C = 0.825[/tex]
[tex]C = \cos^{-1} 0.825[/tex]
[tex]C \approx 34.448^{\circ}[/tex]
The angle ACD is approximately 34.448º.

What is the length of line segment HJ?
Answer:
b = 5√3 (units)
Step-by-step explanation:
To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.
In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.
a^2+b^2 = c^2 (pythagorean therorm)
5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)
25+b^2 = 100 (square the numbers)
b^2 = 75 (subtract 25 from both sides)
b = √75
b = √25 * √3 (factor out√75)
b = 5 * √3 (find square root of√25)
b = 5√3
