Is it possible to use substitution to solve a system of linear equations if one equation represents a horizontal line and the other equation represents a vertical line?
Answer:
NoStep-by-step explanation:
Horizontal line:
y = kVertical line:
x = mThe intersection is (m, k)
No substitution is possible, as no variables to substitute
No
One is horizontal lines
That should be in this form
y=aa is any number
A line is vertical
x=bLook at both equations
a and b are not equal plus there is no x in horizontal line and no y in vertical line.
There is nothing to substitute
The solution will come (b,a)

Classify the triangle by its angle measures. 80 30 70
Answer:
Scalene
Step-by-step explanation:
The three angles have different measures, so the sides have different lengths.
Sometimes it's hard not to assume something from a picture. Just because two of the sides look congruent doesn't mean they are. The information in the diagram (and geometry knowledge and logic!) are your guide.

Step-by-step explanation:
Leah predicts that she will need to contribute $7,000 per year for college tuition and already has $4,000 in savings. She is beginning her Junior year in high school and knows she has 2 years to save to pay for her first year. How much does Leah need to put into her savings account each month to pay for her first year?
Answer:
125 Dollars
Step-by-step explanation:
Total fee = 7000
Amount in hand = 4000
Amount to be saved in 2 years = 7000 - 4000 = 3000
No of months in 2 years = 12 x 2 = 24
Per month saving = 3000 / 24 = 125 $
Max purchased a box of green tea mints. The nutrition label on the box stated that a serving of three mints contains a total of 10 calories. Write an equation that represents C(x). Where C(x) represents the number of calories in 'x' mints. A full box of mints contains 180 calories. Determine the total number of mints in the box.
I WILL GIVE BRANLIEST PLEASE JUST ANSWER BRUV
Answer: equation is
c(x)=(10/3)x
54 mints per box
Step-by-step explanation: ok so 3 mints=10 calories
if you input 3 for number of mints, ou get 10 for caloires
10=k3
divide both sides by 3
10/3=k
therfor
C(x)=(10/3)x
full box =180 caloies
therefor
full=180=(10/3)x
multiplyboth sides by 3/10 to clear fraction (since 10/3 times 3/10=30/30=1)
540/10=x
54=x

15(t-2v)
W-
V
Make v the subject of the formula
Answer:
v=15t/(w+30)
Step-by-step explanation:
multiply by w
wv=15(t-2v)
expand brackets
wv=15t-30v
+30v on both sides
wv+30v=15t
factorize to remove v
v(w+30)=15t
divide by (w+30)
v=15t/(w+30)
After making {v} the subject of the formula, we get -
v = 15t/(w + 2).
What is algebraic expression?An algebraic expression in mathematics is a combination of terms both constant and variable. For example, we can write the algebraic expressions as -
2x + 3y + 5
2z + y
x + 3y
Given is to make {v} the subject of the formula -
w = 15(t - 2v)/v
The given equation is -
w = 15(t - 2v)/v
w = 15t/v - 2v/v
w = 15t/v - 2
w + 2 = 15t/v
v = 15t/(w + 2)
Therefore, after making {v} the subject of the formula, we get -
v = 15t/(w + 2).

Maya has a car loan of $31,470. The loan has a simple interest rate of 5% per year.
What is the amount of interest that Maya will be charged on this loan at the end of one year?
Answer:
$1573.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 31470 × 0.05 × 1 = 1573.5
I = $ 1,573.50
The simple interest accumulated
on a principal of $ 31,470.00
at a rate of 5% per year
for 1 year is $ 1,573.50.

The area of a rectangular field is 7371 m2. If the length of the field is 91 meters, what is its width?
Answer:
81 m
Step-by-step explanation:
From the question given above, the following data were obtained:
Area (A) = 7371 m²
Length (L) = 91 m
Width (W) =?
Area of a rectangle is given by the following equation:
Area = Length × Width
A = L × W
With the above formula, we can obtain the width of the rectangular field as follow:
Area (A) = 7371 m²
Length (L) = 91 m
Width (W) =?
A = L × W
7371 = 91 × W
Divide both side by 91
W = 7371 / 91
W = 81 m
Thus, width of the rectangular field is 81 m

This is solving quadratic functions by square roots btw
Answer:
x = 0
Step-by-step explanation:
add 7 to each side to get:
2x² = 0
divide each side by 2 to get:
x² = 0
take square root of each side to get:
x = [tex]\sqrt{0}[/tex]
x = 0
Answer:
x = 0
Step-by-step explanation:
[tex] {2x}^{2} - 7 = - 7[/tex]
[tex] = {2x}^{2} = 0[/tex]
[tex] = {2x}^{2} \div 2 = 0 \div 2[/tex]

What does A U B mean?
Answer:
Math:The Union of A and B is the set of all those elements which belong either to A or to B or both A and B. use the notation A U B (which is read as 'A union B') to denote the union of set A and set B.
Algebra: n(A U B) = n(A) + n(B) - n(A n B) so 20 = n(A) + 10 - 5 OR n(A) = 15.
