Answer:

65°

Step-by-step explanation:

Sum of interior angles of a triangle = 180°

⇒ m∠EAB = 180 - 90 - 70 = 20°

⇒ m∠DAG = 90 - 45 - 20 = 25°

⇒ m∠AGD = 180 - 90 - 25 = 65°

ΔADG ≅ ΔAFG

⇒ m∠AGD = m∠AGF = 65°

ΔABE ≅ ΔAFE

⇒ m∠AEB = m∠AEF = 70°

Answer:

The rate of change, slope, m is

m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so

m=(39-5)/(21-4)

m=34/17

m=2

So the rate of change is 2

Answer:

it would be the 1st graph

Step-by-step explanation:

this is the graph when the equation is put into a ti calculator! the app i use is wabbit

and it's only available on Android. the pics should be attached! to do this yourself!

also to know without the tool is simply looking at the equation itself and seeing if a negative is in fro

nt of the equation or not which determined if the proabla is flipped or not.

the 1st term in the equation is that number positive or negative? If positive then the proabla is positive and going up, if it has a negative sign then the proabla is going down

Answer:

36/45 and 35/45

Step-by-step explanation:

5 and 9's least common denominator is 45 and to get to that you need to multiply both top and bottom of how to get to 45. How I got to 45 the easiest way is to keep multiplying both numbers until the reach the same product. In this case for 4/5, you multiply it by 9 for top and bottom. And for 7/9, it would be multiplying by 5 for top and bottom which will get you both of the answers. Hopefully this answers your question.

Take 2 points

Slope:-

[tex]\\ \sf\longmapsto y-4=\dfrac{2}{3}(x-0)[/tex]

[tex]\\ \sf\longmapsto 3(y-4)=2x[/tex]

[tex]\\ \sf\longmapsto 3y-12=2x[/tex]

[tex]\\ \sf\longmapsto 3y=2x+12[/tex]

[tex]\\ \sf\longmapsto 2x-3y+12=0[/tex]

Answer:

f(g(x)) = 7x + 27

Step-by-step explanation:

We have, f(x) = 7x+13 and g(x) = x+2.

So, the function f(g(x)) is obtained by substituting the function g(x) = x+2 in f(x) = 7x+13,

i.e. f(g(x)) = f(x+2)

i.e. f(g(x)) = 7 × (x+2) + 13

i.e. f(g(x)) = 7x + 14 + 13

i.e. f(g(x)) = 7x + 27

Thus, f(g(x)) = 7x + 27

Answer: 33.6

60 x 56 divided by 100 is 33.6

The y-intercept is where the x-value is zero.

      [tex]y+2=-(x+1)\\y + 2 = -(0+1)\\y = -1-2 = -3[/tex]

                 Y-intercept of Equation A is (0,3)

       The value of y where x is 0 is -1.

       The Y-intercept of line B is (0,-1)

Hope that helps!

Answer:

See Below.

Step-by-step explanation:

Given :-

Line A equation

Line B graph

To Find :-

Value of the y-intercept of line A and line B

Solving :-

=> y + 2 = -(x + 1)

=> y + 2 = -x - 1

=> y = -x - 3

=> y-intercept is (0, -3)

     2. Line B

=> y = x/4 - 1

=> y-intercept is (0, -1)

Answer:

y=x^2

Step-by-step explanation:

The true equation about the logarithmic equation [tex]\log_xy = 2[/tex] is [tex]y = x^2\\[/tex]

The logarithmic equation is given as:

[tex]\log_xy = 2[/tex]

Apply the change of form logarithm rule.

This rule would convert the logarithmic equation to an exponential equation.

So, we have:

[tex]y = x^2\\[/tex]

Hence, the true equation about [tex]\log_xy = 2[/tex] is [tex]y = x^2\\[/tex]

Answer: 2.7

Step-by-step explanation:

(1)(1/10)+(2)(3/10)+(3)(4/10)+(4)(2/10)=2.7

Solution:

To solve this problem, we will use PRT/100.

Where:

1. Converting the number of months into years.

[tex]\bullet \ \ 1 \ \text{year} = 12 \ \text{months}[/tex]

[tex]\bullet \ \ \rightarrow \text{x years = 12x months = 18 months}[/tex]

[tex]\bullet \ \ \rightarrow \frac{12x}{12} = \frac{18}{12}[/tex]

[tex]\bullet \ \ \rightarrow x = 1.5 \ \text{years}[/tex]

2. Using PRT/100:

[tex]\bullet \ \ \rightarrow \dfrac{P \times R \times T}{100}[/tex]

[tex]\bullet \ \ \rightarrow \dfrac{1900 \times 5.9 \times 1.5}{100}[/tex]

[tex]\bullet \ \ \rightarrow19 \times 5.9 \times 1.5}[/tex]

[tex]\bullet \ \ \rightarrow \boxed{\$168.15}[/tex]

Thus, the interest will be [tex]\bold{\$168.15}[/tex].

Answer: the answer is B,  each term is multiplied by the same number to arrive at the next term

Step-by-step explanation:

Answer:

It's B. Each term is multiplied by the same number to arrive at the next term. as well as D. There is a common ratio between terms.

Step-by-step explanation:

In a geometric sequence, each term is equal to the previous term times a constant, non-zero multiplier called the common factor. Geometric sequences can have a fixed number of terms, or they can be infinite. They must be a progression of terms as well.
