1 answer:
Naddik [55]3 years ago

Answer:

15) <u><em>y= 1/2 + 3.75</em></u>

16) <u><em>y = x</em></u>

Step-by-step explanation:

For #15)

<em>Equation used: y=mx+b ; Slope: y₂ - y₁ / x₂ - x₁</em>

1) First, you need to pick any 2 points on the graph. I'll use (6,3) and (8,4).

2.1) Then you'll use the <em>slope </em>equation to find the slope (m) of your equation.

(y) ~ 4 - 3 = 1

(x) ~ 8 - 6 = 2

Slope= 1/2

3) So from the look of the answers, the y here is 3.75 so you can trust that.

4) The final equation is <u><em>y= 1/2 + 3.75</em></u>

<u><em /></u>

For #16)

Use the same steps as #15. You can still choose whatever points/plots you want. Ima use (5,4) and (6,5).

(y) ~ 4 - 3 = 1

(x) ~ 6 - 5 = 1

slope= 1 or x

Answer: y=x

<em>Your welcome for the answer! <3</em>

In the expansion (ax+by)^7, the coefficients of the first two terms are 128 and -224, respectively. Find the values of a and b
madam [21]

Answer:

a = 2, b = 3.5

Step-by-step explanation:

Expanding (ax+by)^7 using Binomial expansion, we have that:

(ax+by)^7 =

(ax)^7(by)^0 + (ax)^6(by)^1 + (ax)^5(by)^2 + (ax)^4(by)^3 + (ax)^3(by)^4 + (ax)^2(by)^5 + (ax)^1(by)^6 + (ax)^0(by)^7

= (a)^7(x)^7+ (a)^6(x)^6(b)(y) + (a)^5(x)^5(b)^2(y)^2 + (a)^4(x)^4(b)^3(y)^3 + (a)^3(x)^3(b)^4(y)^4 + (a)^2(x)^2(b)^5(y)^5 + (a)(x)(b)^6(y)^6 + (b)^7(y)^7\\\\\\= (a)^7(x)^7+ (a)^6(b)(x)^6(y) + (a)^5(b)^2(x)^5(y)^2 + (a)^4(b)^3(x)^4(y)^3 + (a)^3(b)^4(x)^3(y)^4 + (a)^2(b)^5(x)^2(y)^5 + (a)(b)^6(x)(y)^6 + (b)^7(y)^7

We have that the coefficients of the first two terms are 128 and -224.

For the first term:

=> a^7 = 128

=> a = \sqrt[7]{128}\\ \\\\a = 2

For the second term:

a^6b = -224

b = \frac{-224}{a^6}

b = \frac{-224}{2^6} \\\\\\b = \frac{-224}{64} \\\\\\b = 3.5

Therefore, a = 2, b = 3.5

Every quadrilateral with opposite angles supplementary can be inscribed in a circle.TrueFalseIf a triangle is inscribed in a cir
solniwko [45]

Explanation

The Inscribed Quadrilateral Theorem states that a quadrilateral can be inscribed in a circle if and only if the opposite angles of the quadrilateral are supplementary

Answer 1: True

Also, Given a triangle, the circumscribed circle is the circle that passes through all three vertices of the triangle. The center of the circumscribed circle is the circumcenter of the triangle, the point where the perpendicular bisectors of the sides meet.

Answer 2: True

Solve 2-3x=-x-8 i need help on this question i cant solve this
Nikitich [7]

Answer:

x=5

Step-by-step explanation:

We start by adding 3x to both sides, giving 2-3x+3x=-x+3x-8, which after simplifying gives 2=2x-8.

We then add 8 to both sides, giving 2+8=2x-8+8, which after simplifying gives 10=2x.

We can then divide both sides by 2, giving 10/2=2x/2, which after simplifying gives 5=x, or x=5. So, x is 5.
