I need help ASAP will mark you the brainliest

Mathematics
1 answer:
Vadim26 [7]3 years ago
4 0

Answer:

B

Step-by-step explanation:

<DCE = BCA (vertical angles are congruent)

DC corresponds to CB,

DC/CB = 15/5 = 3

EC corresponds to CA,

EC/CA = 12/4 = 3

Thus, two sides in ∆ABC are proportional to two corresponding sides in ∆EDC, and also, the included angle in ∆ABC and ∆EDC are congruent to each other. Therefore, based on the SAS Similarity Theorem, ∆ABC and ∆EDC are similar.

Given the function g(x) = –11 + 12x + x over 3, evaluate g(4).
Paraphin [41]

g(−3)=2

g(0) = 3g(0)=3

Step-by-step explanation:

Given

The attached graph

Required

Determine

g(-3)g(−3)

g(x) = 3g(x)=3

Since a graph has been provided, the question will be solved graphically;

Solving g(-3)

This implies that;

x = -3

And the interpretation is to solve for the y value when x = -3

From the attached graph;

When x = -3; y = 2

Hence;

g(-3) = 2g(−3)=2

Solving g(x) = 3

This implies that;

y = 3

And the interpretation is to solve for the x value when y = 3

From the attached graph;

When y = 3; x = 0

2 times x plus x plus 45 =180
NARA [144]

Answer:

x= 45

Step-by-step explanation:

2x+x + 45 = 180

Combine like terms

3x+45 =180

subtract 45 from each side

3x+45-45= 180-45

3x = 135

Divide each side by 3

3x/3 = 135/3

x = 45

The mean of four numbers is 85. The four numbers are 86, 83, 81, and .
kati45 [8]

Answer:

90

Step-by-step explanation:

a)

Since, to find the average of a set of numbers, you need to add them all together and divide by the amount of numbers:

\dfrac{86+83+81+x}{4}=85

b)

Multiply both sides by 4:

86+83+81+x=340\\x=90

Hope this helps!
