Parallel to y=2x+1<br> Goes through (5,4)

Ket [755]

      y = mx + b
      y = 2x + 1
y - y₁ = m(x - x₁)
y - 4 = 2(x - 5)
y - 4 = 2(x) - 2(5)
y - 4 = 2x - 10
+ 4     + 4
   y = 2x - 6

Solve 11x+10y=32..... Will mark the brainliest!

erica [24]

The equation 11x + 10y = 32 is a linear equation, and the solution to the linear equation 11x + 10y = 32 is $y = \frac{32 - 11x}{10}$

<h3>How to solve the equation?</h3>

The equation is given as:

11x + 10y = 32

Subtract 11x from both sides

10y = 32 - 11x

Divide both sides by 10

$y = \frac{32 - 11x}{10}$

Hence, the solution to the linear equation 11x + 10y = 32 is $y = \frac{32 - 11x}{10}$

(a+b)2 ;a=1/2 and b=2

FrozenT [24]

Answer:

$\frac{25}{4}$

Step-by-step explanation:

a + b = $\frac{1}{2}$ + 2 = 2 $\frac{1}{2}$ = $\frac{5}{2}$ , thus

(a + b)² = ( $\frac{5}{2}$ )² = $\frac{5}{2}$ × $\frac{5}{2}$ = $\frac{5(5)}{2(2)}$ = $\frac{25}{4}$

What is the measure of EG?

IrinaVladis [17]

The first thing you should know in this case is that a circumference has a total measure in 360 degrees.
We have then that the formula to find EG in this case is:
EG + GF + FE = 360
We cleared EG:
EG = 360-GF-FE
We substitute the values:
EG = 360-83-66
EG = 211
Answer
EG = 211 degrees.
