Answer:
1. -4/7
2. 4/3
3. x^2 + 16x + 63
4. x^2 + 19x + 90
Step-by-step explanation:
1. (1, 8) and (8, 4)
slope = m = (8 - 4)/(1 - 8) = -4/7
2. (2, 4) and (5, 8)
slope = m = (8 - 4)/(5 - 2) = 4/3
3. (x + 9)(x + 7) =
= x^2 + 7x + 9x + 63
= x^2 + 16x + 63
4. (x + 10)(x + 9) =
= x^2 + 9x + 10x + 90
= x^2 + 19x + 90

What is the measure of 2x?
Answer:
130 °
....................
Hi! I'm happy to help!
To solve this, we need to first solve for x.
The total of all the interior angles in a quadrilateral (closed, not curved, shape with 4 sides) is 360°. So, we can single out the xs by subtracting the other angles.
360-89
271
271-76
195
Now that we know that, without the other two angles, the quadrilateral is worth 195. The only 2 angles left have x in them. Since there are 3 xs, we can use this to find out our x.
3x=195
Now, divide both sides by 3.
x=65
Now that we have the value of x, the measure of 2x will just be double that.
65×2
130
The measure of 2x is 130°

1. If a is a subset to B and B is the subset of A, what Else is true about sets A and B
2. List all of the the subsets of {a,b,c}
3. How many subsets are there of {a,b,c,d,e,f}
Answer:
Step-by-step explanation:
1. If A is a subset of B and B is a subset of A then A and B must be equal.
2. The subsets of {a,b,c} are
{ } (emptyset}, {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}
3} Since {a,b,c,d,e,f} has 6 elements then there are [tex]2^6[/tex] subsets.
Convert this rational number
to its decimal form and round
to the nearest thousandth.
1/6
Answer: 0.166
Step-by-step explanation:
Converting to a decimal:
1/6 = 0.1666 (1 divided by 6 - long division)
Rounding:
0.1666 to the nearest thousandth = 0.166
For what values of k will the equation 4x² + 8x + k = 0 have two real solutions?
Answer:
k < 4
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant Δ = b² - 4ac informs us about the nature of the solutions.
• If b² - 4ac > 0 then 2 real and distinct solutions
• If b² - 4ac = 0 then 1 real and repeated solution
• If b² - 4ac < 0 then no real solutions
4x² + 8x + k = 0 ← is in standard form
with a = 4, b = 8 , c = k , then
b² - 4ac = 8² - (4 × 4 × k) = 64 - 16k
For two real solutions
64 - 16k > 0 ( subtract 64 from both sides )
- 16k > - 64
Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity.
k < 4
Then any value less than 4 will ensure the equation has two real solutions

If 18 drinks cost £54, how much will 7 drinks cost ?
Answer:
£21
Step-by-step explanation:
Cost of 18 drinks = £54
Cost of 1 drink
= Cost of 18 drinks/18
= £54/18
= £3
Cost of 7 drinks
= Cost of 1 drink × 7
= £3 × 7
= £21

Hello I need help in my math
12: {x,y,z} ? {a,b,c} is it equal or not?
13: {0} ? { } equal or not?
Please help no spam no links I need help mark brainliest!!
12: Equal, because the cardinal number of {x,y,z} are same as {a,b,c}, that is, 3.
13: Not equal, because in set {0}, there is one element , while in set { } , there are no elements at all .
Hope it helps you. Have a nice day!

4. Solve the following equations and verify your answers: (i) 3 (x + 7) = 18
Answer:
8.33333333333
Step-by-step explanation:
Solution for 3x-7=18 equation:
3x - 7 = 18
3x = 18 + 7
3x = 25 (divide both sides by 3 to get x)
3x/3 = 25/3
x = 8.33333333333

The perimeter of a triangle is 143cm, The sides are x-6, x-6, and 25. Find the length of each side of the triangle
Answer:
12
Step-by-step explanation:
SOLUTION:
In a right triangle, the sum of the squares of the
lengths of the legs is equal to the square of the length
of the hypotenuse. The length of the hypotenuse is 13
and the lengths of the legs are 5 and x.
Perimeter cm, area square cm
Step-by-step explanation:
[tex]perimeter = 2(l + b) = \\ 2(15 + 8) = 2(23) = 46cm \\ area = lb \\ 15 \times 8 = 120 {cm}^{2} \\ thank \: you[/tex]
