Write the slope of the line containing each pair of points.
1. (3, 4) and (5, 7)
2. (5, 2) and (9,4)
Kinda confused on this
Answer:
1) 1.5 2) 0.5
Step-by-step explanation:
To find slope using two points like (x1,y1) and (x2,y2), the slope is (y2-y1)/(x2-x1), so for first question (7-4)/(5-3) = 3/2 = 1.5, and same for the second question.
Last year Jo paid £245 for her car insurance.
This year she has to pay £883 for her car insurance.
Work out the percentage increase in the cost of her car insurance
(3 marks)
Answer:
Increase=638/245*100=260.40
Step-by-step explanation:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.

Find the equation of the straight line which passes through each of the following pairs of points.
(1,4) (3,10)
Answer:
y = 3x + 1
Step-by-step explanation:
First, find slope:
[tex]y2 - y1 / x2 - x1[/tex]
[tex]10 - 4/ 3 - 1 = 6 / 2 = 3[/tex]
Then, put the equation into point-slope form using the point (1, 4):
[tex]y - y1 = m(x - x1)[/tex]
where m is the slope
y - 4 = 3(x - 1)
If you want to put this into slope-intercept form, it would be
[tex]y-4=3(x-1)\\y - 4 = 3x - 3\\y = 3x + 1[/tex]
Two rectangles are similar. The first is 6 inches wide and 4 inches long. The
second is 9 inches wide. Find the length of the second rectangle.
Answer:
It is 6 inches long
Step-by-step explanation:
Since they are similar the ratio of width and length will be the same for both so the ratio for the first one is 2/3 so whats two thirds of 9? 6, and that's your answer. If you have any questions about this just leave a comment

Find the value of x and check the solution.
5 + 4x = -11
Answer:
x=-4
Step-by-step explanation:
5+4x=-11
4x=-11-5
4x=-16
x=-16/4
x=-4
5+4(-4)=-11
5-16=-11
-11=-11
Answer:
x = -4
Step-by-step explanation:
5 + 4x = -11
4x = -11 - 5
4x = -16 (Divide 4 both sides)
x = -4
5 + 4x = -11
5 + 4(-4) = -11
5 - 16 = -11
-11 = -11
HEY CAN ANYONE PLS ANSWER DIS MATH PROBLEM!!!!
Answer: y = (-1/2)x + 8.5
Step-by-step explanation:
A line perpendicular would have a slope that is the negative reciprocal of the given equation.
In this case, the slope is 2, so the perpendicular equation's slope would be -1/2.
We plug in (1, 8) to find b, or the y intercept.
8 = (-1/2)(1) + b
b = 8.5
So the equation would be:
y = (-1/2)x + 8.5

What is the value of y in the equation 2(3y − 6) = 0
Answer:
[tex]y = 2[/tex]
Step-by-step explanation:
1) Divide both sides by 2.
[tex]3y - 6 = 0[/tex]
2) Add 6 to both sides.
[tex]3y = 6[/tex]
3) Divide both sides by 3.
[tex]y = \frac{6}{3} [/tex]
4) Simplify 6/3 to 2.
[tex]y = 2[/tex]
Therefor, the answer is y = 2.
If using the method of completing the square to solve the quadratic equation
x2 + 13x -3 = 0, which number would have to be added to "complete the
square"?
Answer:
Step-by-step explanation:
The term added which completes the square is half of the linear coefficient squared. In a quadratic ax^2+bx+c, b is the linear coefficient, so in this case the added term would be
(13/2)^2=169/4=42.25
The term 13/2 is added to complete the square.
What is a quadratic equation?
A quadratic equation is a polynomial which has the highest degree equal to two. It is a second-degree equation of the form ax² + bx + c = 0, where a, b, are the coefficients, c is the constant term, and x is the variable.
For the given situation,
The quadratic equation is x^2 + 13x -3 = 0.
This is not the perfect square term. So we can solve this by using the completing the square method.
⇒ [tex]x^{2} +13x-3=0[/tex]
⇒ [tex]x^{2} +13x=3[/tex]
⇒ [tex]x^{2} +13x + (\frac{13}{2})^{2} =3+(\frac{13}{2})^{2}[/tex]
⇒ [tex](x+\frac{13}{2} )^{2} =3+\frac{169}{4}[/tex]
⇒ [tex](x+\frac{13}{2} )^{2} =\frac{181}{4}[/tex]
⇒ [tex]\sqrt{ (x+\frac{13}{2} )}^{2} =\sqrt{\frac{181}{4}}[/tex]
⇒ [tex](x+\frac{13}{2})[/tex] = ± [tex]\frac{\sqrt{181} }{2}[/tex]
Hence we can conclude that the term 13/2 is added to complete the square.

The first term of a geometric sequence is 18 and the multiplier is 3.5. What is the 5th term of the sequence?
Answer:
2701.125
Step-by-step explanation:
fifth term = 18(3.5)^4
Answer:
a₅ = 2701.125
Step-by-step explanation:
Multiply each term by 3.5 , that is
a₁ = 18
a₂ = 3.5 × 18 = 63
a₃ = 3.5 × 63 = 220.5
a₄ = 3.5 × 220.5 = 771.75
a₅ = 3.5 × 771.75 = 2701.125
3. A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. 12 radius 18 height
Answer:
8138.88 cubic unit.
Step-by-step explanation:
Given that,
Radius, r = 12
Height, h = 18
We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :
[tex]V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88\[/tex]
So, the volume of the cylinder is 8138.88 cubic unit.
