Answer:
y=-2x+11
Step-by-step explanation:
Slope-intercept form is y=mx+b.
Slope is rise/run, which is y2-y1/x2-x1. Using these points, that's (13-5)/(-1-3). This is 8/-4, or -2.
You can plug this into y=mx+b to get y=-2x+b.
To solve for b, you can use one of the original points and plug it back into the formula:
y=-2x+b
5=-2(3)+b
5=-6+b
b=11
So, putting it all together, you get y=-2x+11.

9514 1404 393
Answer:
89.1 liters
Step-by-step explanation:
"At the same rate" means miles and liters are proportional. The unknown is liters, so we can write the proportion with liters in the numerator:
liters/miles = x/672 = 49/369.6
Multiplying by 672, we have ...
x = 672(49/369.6) ≈ 89.09091
It will take 89.1 liters of gas to go 672 miles.

Answer:
60 would be a good inverse for this table, it is best for xy, 60 is the k/p in this equation.
Step-by-step explanation:
Answer:
1.5
Step-by-step explanation:
The formula for inverse variation is xy=k. So i did 3*5 which is 15 and then I did 15*1 which is 15 and 30*0.5 which is 15. So know i know that 10 times something has to equal 15 so i do 15/10 to get 1.5 which is my answer

Step-by-step explanation:
find the values of a,b, or c for y = x^2 - 9x +18 please help!!
Answer:
It's X^1 = 3, x^2 =6
Step-by-step explanation:
If xy =1 show that dy/dx=-1/x²
If xy = 1, then differentiating both sides with respect to x gives
x dy/dx + y = 0
(use the product rule)
Solve for dy/dx :
dy/dx = -y/x
Solve the starting equation for y and substitute that into the derivative.
xy = 1 → y = 1/x
→ dy/dx = -(1/x)/x = -1/x²

Michael buys a car and agrees to pay $1,500 up front and $450 month for the next 2 years. Which shows the total amount,y, in dollars that will be paid at the end of x months?
Answer:
Total cost= $12,300
Step-by-step explanation:
Giving the following information:
Fixed cost= $1,500
Monthly cost= $450
To calculate the total cost, we need to use the following formula:
Total cost= fixed cost + unitary variable cost*x
x= number of units
For 2 years:
Total cost= 1,500 + 450*24
Total cost= $12,300

A company sells bottles of vitamin capsules. The graph and table show the linear relationship between the cost per capsule in cents and the number of bottles ordered. What is the slope of the line that models this situation?
Answer:
[tex] slope (m) = -5 [/tex]
Step-by-step explanation:
The slope can be calculated using two points, (2, 60) and (4, 50) as shown below:
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex], where,
[tex] (2, 60) = (x_1, y_1) [/tex]
[tex] (4, 50) = (x_2, y_2) [/tex]
Plug in the values into the equation
[tex] slope (m) = \frac{50 - 60}{4 - 2} [/tex]
[tex] slope (m) = \frac{-10}{2} [/tex]
[tex] slope (m) = -5 [/tex]

Henry is using a total of 16 ft. of lumber to make a bookcase. The left and right sides of the bookcase are each
4 ft. high. The top, bottom, and two shelves are all the same length, labeled S. How long is each shelf?
Answer: Each shelf is 2ft
Step-by-step explanation:
16 = (2 x 4) + 4s
16 = 8 + 4s
8 = 4s (subtract 8 from both sides)
8/4 = 4s/4 (divide both sides by 4)
2 = s

The total source voltage in the circuit is 6-3i V. What is the voltage at the middle source
Answer:
The voltage at the middle source is [tex](2-4\mathbf{i})\ V[/tex]
Step-by-step explanation:
Voltage Sources in Series
When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.
The figure shown has three voltage sources of values:
[tex]2 + 6\mathbf{i}[/tex]
[tex]a + b\mathbf{i}[/tex]
[tex]2 - 5\mathbf{i}[/tex]
The sum of these voltages is:
[tex]V_t=4+a+(6+b-5)\mathbf{i}[/tex]
Operating:
[tex]V_t=4+a+(1+b)\mathbf{i}[/tex]
We know the total voltage is [tex]6-3\mathbf{i}[/tex], thus:
[tex]4+a+(1+b)\mathbf{i}=6-3\mathbf{i}[/tex]
Equating the real parts and the imaginary parts independently:
4+a=6
1+b=-3
Solving each equation:
a = 2
b = -4
The voltage at the middle source is [tex](2-4\mathbf{i})\ V[/tex]
The voltage at the middle source is;
E2 = (2 + 4i) V
From the image, we see the voltage at each point as;
E1 = (2 + 6i) V
E2 = (a + bi) V
E3 = (2 - 5i) V
The given voltages are in series and as such the total voltage will be;
E_t = E1 + E2 + E3
We are told that the total source voltage is (6 - 3i)V. Thus;
(6 - 3i) = (2 + 6i) + (a + bi) + (2 - 5i)
Rearranging gives;
(a + bi) = 6 - 3i - (2 + 6i) - (2 - 5i)
(a + bi) = 6 - 3i - 2 - 6i - 2 + 5i
(a + bi) = 2 - 4i
The middle source voltage is E2 = (a + bi) V. Thus;
E2 = 2 - 4i

Answer:
P(-2,4)
Q(2,5)
R(-1,8)
Step-by-step explanation:
The rule for reflecting points across the x-axis is to keep the x-value the same but "negate" the y-value. So, the points above are your answers.

d. Circumcenter:
Answer:
see explanation
Step-by-step explanation:
1
(a)
If 2 chords of a circle intersect then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord.
(b)
If 2 secants are drawn from an external point to a circle then the product of the measures of one secant's external part and the entire secant is equal to the product of the measures of the other secant's external part and that entire secant.
(c)
If a tangent and a secant are drawn from an external point to a circle , then the square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant.

A radian is defined as the angle subtended at the centre of a circle by an arc equal to the radius of the circle.
1 revolution = 360° = 2π radians
1 radian = [tex]\frac{360}{2\pi }[/tex] ≈ 57°

(a)
An inscribed circle of a triangle is a circle drawn inside a circle so the circle barely touches the sides of the triangle.
(b)
The incentre is at the point of intersection of the triangle's 3 angle bisectors.
(c)
A circumscribed circle of a triangle ( circles drawn around the triangle so that the circle passes through each of the triangles's vertices.
(d)
The circumcentre is at the intersection of the perpendicular bisectors of the triangle's sides.
