Find the equation of the line shown
Answer:
y=x+1
Step-by-step explanation:
The slope of the equation is 1, you can try the rise over run method or picking 2 points and subtracting them for example 2,3 and 3,4
2,3-3-4=1,1. The y-intercept is 1 because that is the point where the line crosses the y axis.
Answer:
Slope intercept form:
y = mx + b
Where 'y' is the independent variable and 'x' is the dependent variable.
'm' represents the slope(rise/run), and 'b' represents the y-intercept(where the line meets the y-axis).
If we look at this graph, we can see the line meets the y-axis at 1. So 1, will be our y - intercept.
We can also see, that from the point 1, it rises 1 and goes over 1. So 1, will be our slope as well.
To double check this, we select two fixed points on this graph and subtract the y-coordinates from each other and divide the result of that by the x-coordinates subtracted from each other.
y2(second y-coordinate) - y1(first y-coordinate)
_____________________________________
x2(second x-coordinate) - x1(first x-coordinate)
We pick the two points to be, (1,2) and (2,3).
3 - 2 1
______ = _______, which is equal to 1, so 1 is the slope.
2 - 1 1
Now we insert these values into our slope intercept form equation:-
y = mx + b
y = 1x + 1 or y = x + 1.
Where 1 is the slope, and the y-intercept is 1.

360=164+71+24+x
360=260+x
x=360-260
x=100
Answer:
Step-by-step explanation:
Since angles in quadrilateral (4-sided shape) add up to 360 degrees
therefore,
360 = 164 + 71 + 25 + x
360 = 260 + x
subtract 260 from both sides
360-260 = 260-260 + x
100 = x

The volume of a cylinder is approximately 942 cubic inches. The height of the cylinder is 12 inches. Which is the best approximation for the radius of the cylinder? 4 inches, 6 inches, 7 inches, 5 inches
Answer: 5 inches
Step-by-step explanation:
The volume of a cylinder is equal to pi*radius^2*height.
We can replace the height with 12 inches and the volume with 942 cubic inches.
Therefore, 942 in^3 = pi*radius^2*12 inches
We can divide both sides by 12:
pi*radius^2 = 78.5 inches^2
We can divide both sides by pi:
Radius^2 = About 24.99 inches^2
We can square both sides:
Radius approximately equals 5 inches.

What is an equation of the line that passes through the points (-6,-4) and
(-4,0)?
Answer:
y = 2x + 8
Step-by-step explanation:
the equation of a line in slope-intercept form is.
y = mx+b
where m is the slope and b the y-intercept
to calculate m use the gradient formula
m = (y2−y1 ) / (x2−x1)
let (x1,y1)=(-6,-4) and (x2,y2)=(-4,0)
m = (0 - (-4)) / (-4 - (-6) = 2
y = 2x+b←is the partial equation
to find b substitute either of the 2 given points
into the partial equation
using (-6, -4) then
-4 = -12+b⇒b=8
y = 2x + 8←is the equation of line

The area of the parallelogram is 50 square kilometers. What is the parallelogram's base, b?
Answer:
✓50 km
Step-by-step explanation:
Here, Area of parallelogram = base x height
so, at least two data should be given,
hence, let us consider base = height in this case.
Here it becomes,
Area of parallelogram = base²
50 km² = base²
Now, providing square root on both sides,
we get,
✓50 km = base
Work out the length QR.
Give your answer correct to 3 significant figures.
Total marks: 5
Answer:
The length of QR is 29.9 cm
Step-by-step explanation:
Let us revise the sine and cosine rules
In triangle ABC:
[tex]\frac{AB}{sin(C)}=\frac{BC}{sin(A)}=\frac{AC}{sin(B)}[/tex] ⇒ sine rule
(AC)² = (AB)² + (BC)² - 2(AB)(BC)cos(∠B) ⇒ cosine rule
Let us use these rules to solve the question
In Δ PQS
∵ [tex]\frac{PS}{sin(Q)}=\frac{QS}{sin(P)}[/tex]
∵ PS = 11.7 cm
∵ m∠P = 95°, m∠Q = 28°
→ Substitute them in the rule above
∴ [tex]\frac{11.7}{sin(28)}=\frac{QS}{sin(95)}[/tex]
→ By using cross multiplication
∴ QS × sin(28) = 11.7 × sin(95)
→ Divide both sides by sin(28) to find QS
∴ QS = 24.82680292 cm
Now let us use the cosine rule to find QR
In Δ QSR
∵ (QR)² = (QS)² + (RS)² - 2(QS)(RS)cos(∠QSR)
∵ RS = 10.2 cm
∵ m∠QSR = 110°
→ Substitute these values in the rule above
∴ (QR)² = (24.82680292)² + (10.2)² - 2(24.82680292)(10.2)cos(110)
∴ (QR)² = 893.631984
→ Take √ for both sides
∴ QR = 29.89367799
→ Round it to 3 significant figures
∴ QR = 29.9 cm

Determine whether the sequence is arithmetic, geometric, or neither: 20,17,14,11
==================================================
Explanation:
Add -3 to each term to get the next term. This is the same as subtracting 3 from each term. In this case, the common difference is d = -3.
The first term is a = 20
---------
The nth term formula for the arithmetic sequence is
a(n) = a+d(n-1)
a(n) = 20+(-3)(n-1)
a(n) = 20-3n+3
a(n) = -3n+23
If we plug in n = 1, we would get a(n) = 20. Plug in n = 2 to get a(n) = 17. And so on. This helps confirm we have the correct nth term formula.
