Answer:
x = 8
y = 53
Step-by-step explanation:
Sub y = x + 45 into the second equation
x + 45 = 5x + 13
Rearrange by collecting the like terms
45 - 13 = 5x - x
32 = 4x
Divide both sides by 4
x = 8
Sub x = 8 into first equation (y = x + 45)
y = 8 + 45
y = 53
43 +62 +57 + m / 4 = 55

find the slope and the y intercept of the points (0,1) and (2,-3)
Answer:
The slope is -2 and y intercept is 1
Step-by-step explanation:
The slope is found by finding the run, or change in x coordinates from coordinate 1 to 2, which is 2 in this problem, and the rise, or change in y coordinates from coordinate 1 to 2, which is -4 in this problem. To find the y-intercept, you need to find the point on the line that has a x coordinate of 0, which is (0,1) on this line, which means the y-intercept is the y value of the coordinate, or 1.

What is scientific notation?Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using mathematical symbols.
1. Jupiter, has a mass of about 1,898,000,000,000,000,000,000,000,000 kg.
The scientific notation is:- 2 x 10²⁷ kg.
2. Mercury, has a mass of about 330,000,000,000,000,000,000,000 kg.
The scientific notation is:- 3.30 x 10²³ kg.
Divide Jupiter's mass by the mass of mercury.
Jupiter / Mercury = 2 x 10²⁷ / 3.30 x 10²³
Jupiter / Mercury = 5,751.51

Which of the following does NOT represent the equation y= 2x
Answer:
G
Step-by-step explanation:
In F, the graph goes up by two and only to the side by 1. 2/1 simplifies to 2.
In H, y being the double of x would be equal to 2/1 again.
And in J, the numbers are also being doubled.
The slope for G would just be 0, which is undefined.

Byron’s workout starts with a
warmup at home, and then he runs
at 4 mi/h. After half an hour of
running, he is 2 miles from home.
What is an equation in point-slope form that represents Byron’s
distance from home, y, after
x hours?
Answer:
An equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Step-by-step explanation:
Speed of Byron = 4 miles / hour
Distance traveled in x hours = [tex]Speed \times time[/tex]
Distance traveled in x hours = 4x
We are given that After half an hour of running, he is 2 miles from home
So, Total distance = 4x+2
So, y = 4x+2
Hence an equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2

Some number minus 11 is equal to the product of the number and 18.
Answer:
n - 11 = 18n
Step-by-step explanation:
n−11=18n
Step 1: Subtract 18n from both sides.
n−11−18n=18n−18n
−17n−11=0
Step 2: Add 11 to both sides.
−17n−11+11=0+11
−17n=11
Step 3: Divide both sides by -17.
−17n−17=11−17
n=−1117
Answer:
n = −11/17

Um I kinda need help on this and how to do it
Answer:
m = 1
Step-by-step explanation:
Slope is defined by the change in y over the change in x, [tex]\frac{\Delta y}{\Delta x}[/tex]. A trick here is to find where 2 points where the slope intersects a corner of the square grids. For example, here, it can be (0,1) and (1,0). Then, you count how many squares you needed to go up or down by and divide by the number of square you needed to move right or left by. If you move up or right, the value will be positive and vice versa for down and left. Which direction you go will depend on which point you start on. Here, we can see between (0,1) and (1,0), we need to move up 1 and right 1. Meaning 1/1 is the slope or m = 1. If this doesn't make sense, just ignore it but it may come in handy when you move to more complex problems where the slope is a fraction or something.
Answer:
b= -1
m=1
Step-by-step explanation:
the equation for a linear graph is y=mx+b
your y intercept would be -1 because thats where the line crosses on the y axis. The slope which would be 1 is because when you are on the point (0,-1) you go up one and one to the right and get (1,0)
therefore the equation would be
y=1x-1 or y=x-1
