Answer:
y=51(Alternate interior angles)
z=40(Alternalte interior angles)
x=89(Sum of angles in a triangle)
Solve the triangle if a = 40 and B = 40°.
If the question is asking to look for the third angle, given angle a being 40° and angle b being 40° as well, then we must figure out the total ° that the triangle is (internally), which is 180°.
180 - (40 + 40)
180 - 80
100° is what angle C is

Find the area of this semi-circle with diameter, d = 58cm.
Give your answer rounded to 2 DP.
Answer:
The area of the semi-circle
A = 1320.37 cm²
Step-by-step explanation:
Explanation:-
Given the diameter of the circle 'd' = 58cm
The radius of the circle 'd' = 2r
[tex]r = \frac{d}{2} = \frac{58}{2} = 29[/tex]
The area of the semi-circle
[tex]A = \frac{1}{2} \pi r^{2}[/tex]
[tex]A = \frac{1}{2} (3.14) ((29))^{2}[/tex]
A = 1320.37 cm²

please help me with number 4 it’s been due
Answer:
1. 4y = 3x - 8
2.y-7 = -2(x + 4)
Step-by-step explanation:
1. The general equation form is;
y = mx + b
m is slope b is y-intercept
so we have;
y= 3/4x - 2
Multiply through by 4
4y = 3x -8
2. The point-slope form is;
y-y1 = m(x-x1)
y-7 = -2(x + 4)

Step-by-step explanation:
which of the following is an x intercept of the function f(x)=x^3 -x^2-8x+12
A. 3
B. -4
C. -3
D. 4
Answer:
C
Step-by-step explanation:
Substitute each of the values into f(x) and if equal to zero then it is an x- intercept.
f(3)
= 3³ - 3² - 8(3) + 12 = 27 - 9 - 24 + 12 = 6 ≠ 0
f(- 4)
= (- 4)³ - (- 4)² - 8(- 4) + 12 = - 64 - 16 + 32 + 12 = - 36 ≠ 0
f(- 3)
= (- 3)³ - (- 3)² - 8(- 3) + 12 = - 27 - 9 + 24 + 12 = 0
f(4)
= 4³ - 4² - 8(4) + 12 = 64 - 16 - 32 + 12 = 28 ≠ 0
Since f(- 3) = 0 then x = - 3 is an x- intercept of f(x)
The x - intercept of the function f (x) = x³ - x² - 8x + 12 will be;
⇒ x = - 3
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The function is,
⇒ f (x) = x³ - x² - 8x + 12
Now,
Since, The function is,
⇒ f (x) = x³ - x² - 8x + 12
We know that;
The x - intercept of the function is satisfy the function.
So, We check all the option to find the x - intercept as;
Put x = 3;
⇒ f (x) = x³ - x² - 8x + 12
⇒ f (3) = 3³ - 3² - 8×3 + 12
⇒ f (3) = 27 - 9 - 24 + 12
⇒ f (3) = 6 ≠ 0
Put x = -4;
⇒ f (x) = x³ - x² - 8x + 12
⇒ f (-4) = (-4)³ - (-4)² - 8×-4+ 12
⇒ f (-4) = -64 - 16 + 32 + 12
⇒ f (-4) = - 36 ≠ 0
Put x = -3;
⇒ f (x) = x³ - x² - 8x + 12
⇒ f (-3) = (-3)³ - (-3)² - 8×-3 + 12
⇒ f (-3) = -27 - 9 + 24 + 12
⇒ f (-3) = 0
Thus, The x - intercept of the function is,
⇒ x = - 3

Aubrey invested $7,100 in an account paying an interest rate of 5.6% compounded quarterly. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 19 years?
The amount of money in Aubrey's account after 19 years will be $20,424.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Aubrey invested $7,100 in an account paying an interest rate of 5.6% compounded quarterly.
Assuming no deposits or withdrawals are made.
Then the amount of money in Aubrey's account after 19 years will be
P = $ 7100
r = 0.056/4 = 0.014
n = 4 x 19 = 76
Then we have
A = 7100 (1.014)⁷⁶
A = $ 20,424

How many solutions exist for the given equation?
} (x + 12) = 4x – 1
zero
one
two
infinitely many
Answer:
The given equation has one solution.
Step-by-step explanation:
Given equation is:
(x+12) = 4x-1
We will solve the equation to check how many solutions it has.
x+12 = 4x-1
Adding 1 on both sides
x+12+1 = 4x-1+1
x+13 = 4x
Subtracting x from both sides
x-x+13=4x-x
13 = 3x
x = 13/3
Hence,
The given equation has one solution.
