Since your question doesn't specify what form you need your answer in, I’ll answer in slope intercept form.
Slope intercept form looks like this: y = mx + b.
m represents slope, b represents y intercept. we already have the slope, 2. To find the y intercept, we can plug in the given values for x and y and solve for x.
y = 2x + b
5 = 2(8) + b
5 = 16 + b
- 11 = b
so, the y intercept is - 11. we can plug this into your equation.
y = 2x - 11
There you go! this is your final answer.
Multiplication because b is next to the 3 thus creating Multiplication
<span>x = 18 and the length of each side of the triangle is 29.
This is a matter of reading the descriptions and converting to mathematical notation.
"QRS is an equilateral triangle"
We now know that all three sides of the triangle have the same length.
"If QR is seven less than twice x". So we can write
QR = 2x - 7
"RS is 61 less than 5 times x". So we can write
RS = 5x - 61
"QS is 11 more than x". And we can write
QS = x + 11
And because we already know that they all have the same length, then we can set those equations equal to each other. Let's just pick 2 of them. Will use the length of QR and QS because they look the simplest and then will solve for x.
QR = 2x - 7
RS = 5x - 61
QS = x + 11
2x - 7 = x + 11
x - 7 = 11
x = 18
So we now know that x = 18. Let's check to make sure all three equations have the same value.
QR = 2x - 7 = 2*18 - 7 = 36 - 7 = 29
RS = 5x - 61 = 5*18 - 61 = 90 - 61 = 29
QS = x + 11 = 18 + 11 = 29
And they all are equal, so 18 is the correct value for x.</span>
Yes he can.He can do so by using the tiles to make a 6 by 6 square. 6,6 is a factor pair of 36.
Step-by-step explanation:
a)
6.9+1.1= 8
b)
9.9+2.45=12.35
c)
2.4+8.9=11.3
d)
6.37+7.7=14.07
