−7x−8y=9
−4x+9y=−22
HELP FAST !!!!!!!!!
Answer:
x = 1 , y =− 2
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of
x opposite.
( − 4 ) ⋅ ( − 7 x − 8 y ) = ( − 4 ) ( 9 ) ( 7 ) ⋅ − 4 x + 9 y ) = ( 7 ) ( 22 )
Simplify.
y=-2
x=1
Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
Answer:
£3,692
Step-by-step explanation:
First four years
A = p(1 + r/n)^nt
P = £2350
r = 4.2% = 0.042
n = 1
t = 4
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Next 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692

Find the missing length.
Answer:
Triangle 1 - 4
Triangle 2 - 10
Step-by-step explanation:
To find the missing side lengths of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem states that: a² + b² = c². In this equation, a and b are legs, and c is the hypotenuse.
Using this to solve triangle 1, you get the equation: a² + 3² = 5² or a² + 9 = 25. To solve for a², you subtract 9 from both sides to get a² = 16. To solve for a, find the square root of 16, which is 4.
Using the Pythagorean Theorem to solve for triangle 2, you get the equation: 6² + 8² = c² or 36 + 64 = c². Add 36 + 64 to get 100 = c². Find the square root of 100 to solve for c. The square root is 10.
Hope it helps!
Henry places £6000 in an account which pays 4.6% compound interest each year
Calculate the amount in his amount after 2 years
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

Use the table below to determine whether f(x) could represent a linear function. If it could write f(x) in the form f(x) = mx +b.
Answer:
5x-3
Step-by-step explanation:
This is linear because the numbers are changing at a constant rate (of 5)
We can also see that when x=0 y= -3 which means that in our equation
y=mx+b
-3 =b
I said prior that the rate of change is 5 which means that our slope is 5
which means that our equation looks like
5x-3
