If the equations are the same then the solution will be the same. Then the correct option is D.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The linear equations are given below.
-3x - 8 = 19 ...1
-3x - 2 = 25 ...2
Adding 6 on both sides in equation 1, then we have
-3x + 6 - 8 = 19 + 6
-3x - 2 = 25
The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.
If the equations are the same then the solution will be the same.

Triangle ABC is similar to triangle DEF.
a. Find the scale factor from triangle ABC to triangle DEF.
b. Find x.
c. Find y.
Answer: x=7.7, y=40
3/x = 15/38.5
38.5*3=115.5
115.5/15= 7.7
x=7.7
3/8 = 15/y
15*8=120
120/3= 40
y=40
orrrr you can just easily find the scale factor which is 5, multiply 8 by 5 and get 40. And 38.5/5 which is 7.7

Assume that 48% of the voters in New York favor a certain legislative proposal. De- termine how many voters in New York need to be sampled so that the magnitude of the difference between the observed relative frequency of those favoring the proposal and the population frequency does not exceed 0.01 with probability 0.99.
The number of the voters in the Newyork need to be sampled will be P=19,782.
What is Probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
It is given in the question that:-
Voters percentage=48%
Margin of error=0.01
Z value at 0.99 = 2.58
By using the formula:-
[tex]\rm M=z\sqrt{\dfrac{\pi(1-\pi)}{n}[/tex]
By putting the values:-
[tex]0.01=2.58\sqrt{\dfrac{0.48(1-0.48)}{n}[/tex]

Communicate Precisely: Suppose the numbers on the clock face are removed.
Write instructions that another person could follow to move the minute hand from 2 to 6.
In order to move the minute hand from 2 to 6 first move 60 degrees clockwise then 120 degrees clockwise.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
On a clock, numbers 1 to 12 are printed on it.
If numbers on the clock face are removed.
As we know, the clock is a circle and has a total angle of 360 degrees.
Angle between the two numbers = 360/12 = 30 degree
Then the following instructions have to be followed in order to move the minute hand from 2 to 6:
Set the minute hand vertically up.Move 60 degrees in a clockwise direction, it will be on number 2.Now move 120 degrees in a clockwise direction, it will indicate the number 6.Thus, in order to move the minute hand from 2 to 6 first move 60 degrees clockwise then 120 degrees clockwise.

Write an equation in slope-intercept form for the relationship in the table.
The equation of the relationship in the table, in slope-intercept form, is: y = x + 5.
What is the Slope-intercept Form?The slope-intercept form for a relationship between two variables x and y is represented as: y = mx + b, where:
m = slope = change in y / change in xb = y-intercept.Slope (m) = change in y / change in x = 47 - 42 / 42 - 37 = 5/5
Slope (m) = 1
Substitute (37, 42) = (a, b) and m = 1 into y - b = m(x - a):
y - 42 = 1(x - 37)
y - 42 = x - 37
y = x - 37 + 42
y = x + 5

Find the lateral area and surface area of the regular square pyramid.
Round to nearest tenth.
Answer:
Step-by-step explanation:
lateral edge is an edge from the base to the vertex. As opposed to a base edge.
If the base edge is 6, the base diagonal is 6√2
Now draw a right triangle from the center of the base to the vertex, including one base corner.
(6√2/2)^2 + h^2 = (√34)^2
18 + h^2 = 34
h = 4
So, now we have height 4 and base edge 6, so the faces are triangles with
base = 6
height = √(3^2 + 4^2) = 5
lateral area is thus 4 * 1/2 (6)(5)
add the square base if desired.

Area = 5.612 * 10^14 cm^2
Find: Perimeter - ?
Area = a * bb = Area / ab = (5.612 * 10^14) / (9.2 * 10^7) = 0.61 * 10^7 cm
Perimeter = (a + b)*2Perimeter = (9.2 * 10^7 + 0.61 * 10^7) * 2 = (9.2 + 0.61) * 10^7 * 2 = 9.81 * 2 * 10^7 = 19.62 * 10^7 cm
