4х – Зу = 15
x - 2y = 0 solve using substitution please show work
Answers
Answer:
(6,3)
Step-by-step explanation:
I'm going to start with the second one.
x - 2y = 0
+2y +2y
x = 0 + 2y which is the same as (x = 2y)
Now plug that in for the x-value in the other equation.
4(2y) - 3y = 15
8y - 3y = 15
5y = 15
Divide both sides by 5
y = 3
Here is where you are going to plug it back into the first one we did.
x - 2(3) = 0
x - 6 = 0
+6 +6
x = 6
So the answer is (6,3)
Hope that helps and have a great day!

Peter says there are two distances for which he and Maria charge the same amount. To prove Peter is not correct, Maria graphs a line for her delivery charges and a line for Peter’s delivery charges. Each line represents the relationship between the amount (y), in dollars, each person charges for a delivery and the distance (x), in miles, each drives for the delivery. Without showing the graph, explain how Maria’s graph of the two lines proves Peter is not correct.

the area of a trapezium is given by the formula A=1/2h(a+b), where h is the height and a and b are the measures of the two bases. what is the height of a trapezoid with an area of 24 square inches if the two bases measure 4 inches and 6 inches?
Answers
Answer:
[tex] h = 4.8 \: inches.[/tex]
Step-by-step explanation:
[tex]A= \frac{1}{2} h(a+b) \\ h(a + b) = 2A \\ h = \frac{2A}{(a+b)} = \frac{2 \times24 }{4 + 6} \\ h = \frac{48}{10} \\ h = 4.8 \: inches.[/tex]
Answer:
h=4.8
Given:
area=24 , a=4 , b=6
To find:
height
Step-by-step explanation:
A = [tex]\frac{1}{2}[/tex] × h(a+b)
24 = [tex]\frac{1}{2}[/tex] × h(4+6)
24 × 2 = h(10)
48 = 10h
48/10 = h
h=24/5
h=4.8
therefore, height of the trapezium is 4.8

Answer fast I will name you the most Brainly please help
Answers
9514 1404 393
Answer:
g - 4 = 9
Step-by-step explanation:
If the number is g, then four less than the number is g-4.
If that is 9, then you have the equation ...
g - 4 = 9
_____
Additional comment
If you add 4 to both sides of the equation, you have its solution.
g -4 +4 = 9 +4
g = 13
So, 4 less than 13 is 9.

standard to slope intercept form
Answers
Answer:
[tex]y=\frac{5}{3}x+8[/tex]
Step-by-step explanation:
Remember, slope intercept form is:
y = mx + b
where m is the slope and b is the y-intercept.
To get the given equation into slope-intercept form, we would have to first solve for y in terms of x.
10x - 6y = -48
Subtract 10x from both sides.
-6y = -48 - 10x
Multiply both sides by -1.
6y = 10x + 48
Divide both sides by 6.
[tex]y=\frac{5}{3}x+8[/tex]
And now, looking at the equation that we found and the equation for slope-intercept form, we can see that we have found the equation for 10x - 6y = -48 in slope-intercept form.

Letter: 8.5 inches by 11 inches Legal: 8.5 inches by 14 inches Junior legal: 5 inches by 8 inches Tabloid: 11 inches by 17 inches a. Are any of the paper sizes similar? b. The dimensions of government-letter paper are each 0.5 inch less than the dimensions of letter paper. Are these paper sizes similar? Question 2 c. By increasing the shorter side of legal paper by inch, it is similar to the size of junior legal paper.
Answers
Answer
a. No none are similar.
b. No.
c. Even if it were to be increased it still won’t be similar as what we would get would be 133 inches.
Step-by-step explanation:
LETTER = 8.5inches * 11 inches = 93.5inches.
LEGAL = 8.5inches * 14 inches = 119 inches
Junior legal: 5 inches * 8 inches = 40inches.
Tabloid: 11 inches * 17 inches = 187 inches
Government paper = 8inches * 10.5 inches = 84 inches.
