Answer:
False
Step-by-step explanation:
y=x-2 y=3x+4
Substitute the point into both equations and see if it is true
2=4-2
2=2 true
and
2=3*4+4
2 = 12+4
2 =16
False
It is not a solution
Answer:

Step-by-step explanation:
<u>Rational Numbers</u>
A rational number is any number that can be expressed as a fraction

for a and b any integer and b different from 0.
As a consequence, any number that cannot be expressed as a fraction or rational number is defined as an Irrational number.
Let's analyze each one of the given options

The first part of the number is indeed a rational number, but the second part is a square root whose result cannot be expressed as a rational, thus the number is not rational

The second part is an exact square root (resulting 4) but the first part is a known irrational number called pi. It's not possible to express pi as a fraction, thus the number is irrational

The square root of 121 is 11. It makes the whole number a sum of a rational number plus an integer, thus the given number is rational

As with the first number, the square root is not exact. The sum of a rational number plus an irrational number gives an irrational number.
Correct option:

Answer: 32 buttons
Step-by-step explanation:
Matt has 11 white buttons.
Matt has 9 fewer brown buttons than white buttons. This means he has (11 -9) = 2 brown buttons
Matt has 17 more grey buttons than brown buttons. This means that he has (2 + 17) = 19 grey buttons.
The total number of buttons that Matt has will be;
= 11 white + 2 brown + 19 grey
= 32 buttons
Answer:
y = 3x+9
Step-by-step explanation:
The standard form of equation of a line is in the form y = mx + c
m is the gradient
c is the y intercept
Get the y-intercept
Substitute m = 3 and the point (-2, 3) into the formula y = mx+c
3 = 3(-2) + c
3 = -6+c
c = 3+6
c = 9
Get the required equation;
y = 3x + 9
Hence the required equation is y = 3x+9
None because two sides of the triangle added together have to be greater than the other side
