x = 5 and y = 8
Step-by-step explanation:
y = 3x - 74x - 5y = -20→ Subtitute the value of y to second equation :
4x - 5y = -20
4x - 5(3x - 7) = -20
4x - 15x + 35 = -20
-11x + 35 = -20
-11x = -20 - 35 → (multiplied by -1)
11x = 20 + 35
11x = 55
x = 5
→ Subtitute x to one of Equation :
For example i take from First Equation…
y = 3x - 7
y = 3(5) - 7
y = 15 - 7
y = 8
∴ So, the value of x = 5 with y = 8

Answer:
The estimate is too low
Step-by-step explanation:
46×6=276 which isn't a very close estimate. However if you used 46×7=322 the estimate would be OK. Now if you used 46×8=368 that would be too high of an estimate here. In simpler terms 1 to 6 is too low of an estimate here and 8 to 9 is too high of an estimate. The number 7 is the middle ground here. Hope this helped.
Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.
Count the boxes each as 1.

Convert 56∘F to ∘C.
Round to one decimal place and do not include units in your answer.
What formula are you using I'm using the one below so hopefully you're able to utilize this.
C = (F-32) ÷ 1.8
C = (56-32) ÷ 1.8
C = ( 24 ) ÷ 1.8
C = 13.3333333
Rounding one decimal place (tenths)
C = 13.3

Yep sorry again this math is hard
Answer:
<
Step-by-step explanation:
Firstly, you can focus on the scientific notation and calculate which one is bigger. The left side is [tex]10^3[/tex] whereas the right side is [tex]10^4[/tex]. This shows that even if the number before this was bigger, the larger exponent of these two are the bigger number.
[tex]10^3 = 1000\\10^4 = 10000[/tex]
Meaning the correct sign would be the smaller than sign (<) as the right side is bigger than the left.

The answers are :
a) The graph is translated downwards by 4 units.
b) The graph is translated downwards by 2 units.
What do you mean by translation of a graph ?
The modification of an existing graph or graphed equation to create a different version of the following graph is known as translation.
a)
The graph of y = f(x) is shown.
The other function is y = f(x) - 4.
As it can be observed that the graph is translated from its parent function which is y = f(x) to function y = f(x) - 4.
The graph is shifted down by 4 units or translated downwards by 4 units.
b)
Here , the graph of y = g(x) is shown.
The other function is y = g(x -2)
As we can observe that the graph is translated from its parent function which is y = g(x) to function y = g(x - 2).
The graph is shifted downwards by 2 units or translated downwards by 2 units.
Therefore , the answers are :
a) The graph is translated downwards by 4 units.
b) The graph is translated downwards by 2 units.

Answer:
x=5
Step-by-step explanation:
2(x + 4) = 18
Divide each side by 2

Answer:
(a) 29/69
Step-by-step explanation:
It can help to be familiar with divisibility rules. Even numbers are divisible by 2, so the fraction 174/414 can immediately be reduced to 87/207.
Both numbers have a digit total that is divisible by 3, so each of these numbers can further be divided by 3, reducing the fraction to 29/69. The number 29 is prime, so this fraction cannot be reduced further.
The reduced fraction is ...
made shots/attempts = 174/414 = 29/69
__
Additional comment
As is often the case, a calculator can help you identify arithmetic expressions that have the same value (are equivalent).
174/414 ≈ 0.42028986
29/69 ≈ 0.42028986 . . . . same value
87/207 ≈ 0.42028986 . . . . same value, but 29/69 is reduced
17/41 ≈ 0.41453415 . . . . . not equivalent
14/46 ≈ 0.30434783 . . . .not equivalent (and not reduced; both numbers are even)

Answer:
(d) y = 2×7^x
Step-by-step explanation:
If you try x=2 in each of the expressions, you find only one of the gives 98 as the value.
a) 14^2 = 196
b) 7×2^2 = 28
c) 2^(7×2) = 2^14 = 16,384
d) 2×7^2 = 2×49 = 98 . . . . . . . correct answer choice
__
Alternatively, you can recognize that the x-values in the given (x, y) pairs differ by 1, so the ratio of y-values will be the base of the exponential term:
98/14 = 7
so you're looking for something of the form 7^x. That would be ...
y = 2×7^x
__
In more general terms, consider
y = ab^x
If you have x=1 and x=2, then this will be ...
y1 = ab^1 = ab
y2 = ab^2
Dividing the second by the first gives ...
y2/y1 = (ab^2)/(ab) = b . . . . . . . general solution when x-values differ by 1
98/14 = b = 7
From the x=1 case, we have ...
14 = 7a ⇒ a = 2
y = 2·7^x
solve include real and non real solutions.
