MZ3 = 64 m_4 = 106° and 4 2 3 1 What is mZ1,

ddd [48]

Answer: m∠1=42°

Step-by-step explanation

For this problem, we can separate the triangle into 2 separate triangles to solve for m∠1.

We know that m∠4 is 106°. ∠2 and ∠4 are supplementary angles. You can see that they make a straight line of 180°. We can use this fo find ∠2.

∠2+∠4=180

∠2+106=180

∠2=74°

Now that we know ∠2 is 74°, we can use that to solve for m∠1.

We know that the measures of the angles in a triangle equal to 180°. For the triangle at the bottom, we see ∠3, ∠2, ∠1. Since we know ∠3 and ∠2, we can find ∠1.

∠3+∠2+∠1=180

64+74+∠1=180

138+∠1=180

∠1=42°

Please please need help on these two

kati45 [8]

Answer:

( f + g ) (x) = $2 x^{2} + x - 4$

g(x) - f(x) = $x^{2} - 2 x - 4$

Step-by-step explanation:

f(x) = 4 x - 4 and g(x) = $2 x^{2} - 3 x$

( f + g ) (x) = f(x) + g(x)

= $4 x - 4 + 2 x^{2} - 2 x$

= $2 x^{2} + x -4$

2. g(x) = $x^{2} + 1$ and f(x) = 2 x + 5

g(x) - f(x) = $x^{2} + 1 - (2 x + 5)$

= $x^{2} + 1 - 2 x - 5$

= $x^{2} - 2 x - 4$

How do you write y+1=4/5(x-3) in standard form?

Rudik [331]

Answer:

The standard form of the given expression is $- (\frac{4}{5})x + y + (\frac{17}{5}) = 0$

Step-by-step explanation:

Here, the given expression is $y + 1 = \frac{4}{5} (x-3)$

Now, the Standard Form of the equation is ax + by + c = 0

Solving this, we get:

$y + 1 = \frac{4}{5} (x-3) \implies y + 1 = (\frac{4}{5})x - \frac{12}{5}$

⇒ $y + 1 - (\frac{4}{5})x + (\frac{12}{5}) = 0$

or, $y - (\frac{4}{5})x + (\frac{12}{5} + 1 )= 0 \implies y - (\frac{4}{5})x + (\frac{12+ 5}{5}) = 0$

⇒ $y - (\frac{4}{5})x + (\frac{17}{5}) = 0$

Hence, the standard form of the given expression is $- (\frac{4}{5})x + y + (\frac{17}{5}) = 0$

What graph best represents y=2^x + 1

Citrus2011 [14]

Answer:

The graph that best represents the given equation in the attached figure

Step-by-step explanation:

we have

$y=2^x+1$

Find the y-intercept

Remember that the y-intercept is the value of y when the value of x is equal to zero

For x=0

substitute

$y=2^0+1=2$

The y-intercept is the point (0,2)

The given function is increasing, because the y-value increases as the x-value increases. The function tends to go up as it goes along

therefore

The graph that best represents the given equation in the attached figure
