Answer:
B
Step-by-step explanation:
One way to tell is to put both equations into slope-intercept form. That form is usually written [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.
Solve the first equation for y.
[tex]6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2[/tex]
The slope of this line is -3, and its y-intercept is 5/2.
Solve the second equation for y.
[tex]y+3x=2\\y=-3x+2[/tex]
The slope of this line is -3 and its y-intercept is 2.
The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.

The first one (highlighted one)
Step-by-step explanation:
The answer is the one selected. When multiplying and subtracting numbers, you do the combination that is multiplying before you subtract-unless there are numbers in parenthese. You work parentheses first. In all of the other options, you are multiplying first so not subtracting from 3. For example the second option, you would multiply 4x7 BEFORE you subtract from 3 which doesn’t work. You are also multiplying first in options 3 and 4.

A population of 2500 frogs increases exponentially at an annual rate of 25%. Which equation below best represents the population (P) in t years?
P=2500(0.25)^t
P=2500+0.25t
P=2500(0.75)^t
P=2500(1+0.25)^t
Answers
Answer:
P=2500(1+0.25)
Step-by-step explanation:
Given data
Initial population= 2500
Rate= 25%
The exponential increase is described using the expression
P=A(1+r)^t
Hence the correct representation is
P=2500(1+0.25)

The number of people who could be expected to buy a flag using the expression (22/200) x 25,000 is 2,750.
Option D is the correct answer.
We have,
Based on the table,
The number of people who could be expected to buy a flag out of 25,000 visitors is:
(22/total items sold) x 25,000
To find the total items sold, you can add up the number of caps, jerseys, flags, and programs:
Total items sold.
= 68 + 19 + 22 + 91
= 200
The number of people who could be expected to buy a flag is:
(22/200) x 25,000 = 2,750
Thus,
The number of people who could be expected to buy a flag is 2,750.

What is the surface area of the rectangle below?
Answers
Step-by-step explanation:
First, we must take into account that there will be 3 pairs of sides that are the same. Starting at the front, we have 9 * 12. Since the rectangular prism is measured in units squared, this side is 108 units squared. The opposite side is the same. Our current total is 216 units. The side is 15 * 9. This is 135 units, multiplied by 2 since it has the other side, to get 270 units. Our current total is 486 units, so it already can't be A. The top and bottom sides are 15 * 12 units, giving us 180 on each, 360 in total. 360 plus 486 = 846 units squared.

The base of the triangle is 4 inches more than the length of the sides and the total the total perimeter is 64 inches. Write an equation to find the length of each side of the triangle
Answers
Answer:
Both the sides are equal to 20 inches and the base is equal to 24 inches.
b=s3= s1+4----equation 1
s1=s2----equation 2
Perimeter of the triangle = s1+s2+s3--------equation 3
Step-by-step explanation:
Let the sides be denoted by s1 and s2 . Then the base is denoted by b=s3= s1+4----equation 1
According to the statement s1=s2----equation 2
Perimeter of the triangle = s1+s2+s3--------equation 3
64= s1+s2+ s1+4
64 = 3s1+4
60= 3s1
20 = s1
Both the sides are equal to 20 inches and the base is equal to 24 inches.

Step-by-step explanation:
vol = Bh where B is the area of the base and h is the height of the cylinder
The base is a circle so
B = [tex]\pi r^{2}[/tex] h = 5
141.3 = 3.14(5)[tex]r^{2}[/tex]

3 /2 (x−6)=−3
( 3 /2 )(x)+( 3 /2 )(−6)=−3(Distribute)
3 /2 x+−9=−3
3 /2 x−9=−3
Step 2: Add 9 to both sides.
3 /2 x−9+9=−3+9
3 /2 x=6
