Answer:
angle 1 should equal to 54.
angle 2 should equal to 126.
Step-by-step explanation:
2x - 8 + 4x + 2 = 180
2x + 4x - 8 + 2 = 180
6x - 6 = 180
6x - 6 + 6 = 180 + 6
6x = 186
6x ÷ 6 = 186 ÷ 6
x = 31
---------------------------------------------
2x - 8 = A1
2(31) - 8 = A1
62 - 8 = A1
54 = A1
-----------------------------------------------
4x + 2 = A2
4(31) + 2 = A2
124 + 2 = A2
126 = A2

Henry places £6000 in an account which pays 4.6% compound interest each year
Calculate the amount in his amount after 2 years
Answers
Answer:
£ 6,564.70
Step-by-step explanation:
Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years
Compound Interest formula =
A = P(1 + r/n)^nt
A = Final Amounrt
P = Principal = £6,000
r = Interest rate = 4.6%
t = Time in years = 2 years
n = Compounding frequency = Yearly = 1
First, convert R percent to r a decimal
r = R/100
r = 4.6%/100
r = 0.046 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 6,000.00(1 + 0.046/1)^(1×2)
A = £ 6,564.70
The amount in his account after 2 years = £ 6,564.70

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Answers
Given:
Jake bought 3 drawing pens for $8.07.
Each pen costs the same amount.
To find:
How much did he spend for one pen?
Solution:
Let x be the cost of each pen. Then
Cost of three pens = 3x
Jake bought 3 drawing pens for $8.07.
[tex]3x=8.07[/tex]
Divide both sides by 3.
[tex]x=\dfrac{8.07}{3}[/tex]
[tex]x=2.69[/tex]
Therefore, he spend $2.69 for one pen.

Jorge has 24 ounces of baking powder to use for baking loaves of bread. if each loaf of bread requires 1/4 of an ounce of baking powder, how many loaves of bread will Jorge be able to bake?
Answers
Answer:
96 loaves of bread
Step-by-step explanation:
Total baking powder = 24 ounces
Baking powder used per loaf of bread = 1/4 of an ounce
loaves of bread will Jorge be able to bake = Total baking powder / Baking powder used per loaf of bread
= 24 ÷ 1/4
= 24 × 4/1
= 96 loaves of bread
loaves of bread will Jorge be able to bake = 96 loaves of bread

What is the solution to the system of equations?
6 x + 2 y = 6. 7 x + 3 y = 5.
Answers
Answer:
x = 2, y = -3
or
(2, -3)
Step-by-step explanation:
6x + 2y = 6
7x + 3y = 5
multiply the first equation by -3 and the second equation by 2 and solve by elimination
6x + 2y = 6
becomes
-18 - 6y = -18
7x + 3y = 5
becomes
14x + 6y = 10
then, add the new equations.
-18x - 6y = -18
14x + 6y = 10
-4x + 0 = -8
-4x = -8
4x = 8
x = 2
then, substitute x for 2 in one of the eqautions.
6x + 2y = 6
12 + 2y = 6
2y = 6 - 12
2y = -6
y = -3

The graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The equation y = 2ˣ⁻⁴ - 3 is an exponential function that has been shifted 4 units to the right and 3 units down from the basic exponential function y = 2ˣ.
If we change the -3 to a 3, we get the new equation:
y = 2ˣ⁻⁴ + 3
This new equation represents the original exponential function shifted 4 units to the right and 3 units up.
Therefore, the graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.

What is the solution to the equation 2(x+7)=-4x+14
Answers
Answer:
x = 0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x+7)=−4x+14
(2)(x)+(2)(7)=−4x+14(Distribute)
2x+14=−4x+14
Step 2: Add 4x to both sides.
2x+14+4x=−4x+14+4x
6x+14=14
Step 3: Subtract 14 from both sides.
6x+14−14=14−14
6x=0
Step 4: Divide both sides by 6.
6x 0
6 = 6
x=0

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the
exponential equation?
Answers
Sorry for tje late answer but it is 150 * 0.08^x
The exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].
What is depreciation?Depreciation is the rate by which the value of an object reduces with respect to time. it is given by the formula,
[tex]A = P(1-\dfrac{r}{100})^t[/tex]
where A is the value of object after t period of time, P is the principal amount, r is the rate of depreciation, and t is the time period.
We know the formula of the depreciation, Also, the initial value of the car is $15,000, and the rate of depreciation r that is 8% per year. Therefore, the function of the depreciation of the car can be written as,
[tex]A = P(1-\dfrac{r}{100})^t\\\\A = 15000(1-\dfrac{8}{100})^t\\\\A = 15000(1.08)^t[/tex]
Hence, the exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].
