state the gradient and the y-axis intercept of
y=3x+7
Step-by-step explanation:
the slope (or gradient) of a line is the factor of x.
in our case here : 3
it is expressed as ratio y/x and represents the amount of units y changes (and via the sign in what direction), when x changes a certain amount of units (again, via the sign in what direction). like when going from a point 1 to a point 2.
so, here we have 3 = 3/1, and that means, when x changes by 1 unit to the right (positive), y changes 3 units up (positive).
the y-axis intercept is simply the point, where x = 0. clearly, any point with the x coordinate being unequal to 0 cannot be on the y axis.
so, here
y = 3×0 + 7 = 7
=>
the y-axis intercept point is (0, 7).
solve for u
-4+ u =-2
u=?
Answer:
u = 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]-4 + u = -2[/tex] [tex]u - 4 = -2[/tex]Step 2: Add 4 to both sides.
[tex]u - 4 + 4 = -2 + 4[/tex] [tex]u = 2[/tex]Therefore, u = 2.

Find the distance between M(6, -7) and a line that contains
C(-6, -2) and H(-1, 10).
Answer
Step-by-step explanation:
i really need help with it
The distance between M and C is √61 and distance between M and H is 13√2.
What is distance formula?The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula.
Assume that 'd' is the distance between A and B.
d =√(x2 - x1)² + (y2 - y1)²
Given coordinates:
M(6, -7) and a line that contains C(-6, -2) and H(-1, 10).
Now, distance between M and C
=√(-6 -6)² + (-2 + 7)²
=√36 + 25
= √61
and, MH
=√(-1-6)² + (10 +7)²
=√49+ 289
= √ 338
= 13√2

Answer:
A) Dilated 150% then reflected across the x-axis
Step-by-step explanation:
By counting the squares of shape A, you can see that 2 squares = 100% and 1 square = 50%. You can then count 2 squares into shape B (because that is your starting point) and then count the remaining squares, which is 3. 3 squares is equal to 150% so we know there is a 150% dilation.
We can then also see shape A has been reflected across the x-axis to give shape B.

In Earth's southern hemisphere, the summer season is from December to March and winter is from June to September. The table shows the highest temperatures recorded at the South Pole for three different months.
Graph model:
South Pole Temperatures
Month Highest temperature (°F)
January 6
June –24
November –2
Each month's highest recorded temperature is plotted on the number line.
Which of these months had the lowest high temperature? (ignore this)
1. Write the three temperatures in order from least to greatest. Explain how you put the numbers in order.
2. Which month had the lowest high temperature?
3. Which month had the highest temperature?
Answer:
1: (-24, -2, 6) 2: June 3:January
Step-by-step explanation:
1: the closer the negatives get to 0 backwards, the higher the temperature is, and after 0 would be even higher.
2: -24 is the most far back from the other two
3: 2 of them are negatives and the other is positive so the positive number would be the highest temp
Answer:
1. -24,-2,6
We order this way as the value of an integer decreases when we go lower below 0
2. The lowest High temperature is in June when the temperature is -24
3. January has the highest temperature because the highest temperature was above 0 which was 6

Although the actual amount varies by season and time of day, the average volume of water that flows over the falls each second is 3.2 x 10^5 gallons. How much water flows over the falls in an hour? Write the result in scientific notation. (Hint: 1 hour equals 3600 seconds)
Answer:
1.152 x 10^9 gal/hr
Step-by-step explanation:
Given:
3.2 x 10^5 gal / 1 sec
1 hr = 3600 s
Convert:
[tex]\frac{3.2 x 10^5 gal}{1 sec} * \frac{3600 sec}{1 hr}[/tex]
By this, seconds cancel out leaving us with gal/hr, which is what we need.
= 1152000000

feet?
The inequality expression for the number of years when tree will be atleast 20 feets tall is x ≥14
Current height = 2 Growth rate = 1.3 feets per yearThe height of the tree after x years can be represented as a linear equation thus :
Height = 2 + 1.3xNumber of years when the tree will be 20 feets tall :
20 = 2 + 1.3x 20 - 2 = 1.3x 1.3x = 18x = 13.84The tree would be atleast 20 feets tall in 14 years x this can be expressed thus
