Mathematics
1 answer:
Radda [10]4 years ago
6 0

Answer:

C. No solution.

Step-by-step explanation:

y = −2x + 1

4x + 2y = −1

Substituting y = -2x + 1 in the second equation:

4x + 2(-2x + 1) = -1

4x - 4x + 2 = -1

2 = -1  which is  absurd so there is no solution.

Fittoniya [83]

Answer: 172 square centimeters.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Area of a pentagon (A) = 1/2× 5s × a

Where:

s : side of the pentagon

a: apothem

Replacing with the values given and solving for A (area):

A =1/2 x (5 x10) x 6.88

A = 172 square centimeters.

STatiana [176]
Let the length of the shorter sides be x, then
Perimeter = x + x + x + 5
29 = 3x + 5
3x = 29 - 5 = 24
x = 24/3 = 8

Therefore, the length of longest side is 8 + 5 = 13 m.

Which of these statements is true for f(x) = 2.3*?
Marina86 [1]

The true statement for f(x) = 2(3)^x is the y-intercept is (0, 2).

<h3>How to determine the true statement?</h3>

The function is given as:

f(x) = 2(3)^x

Set x = 0 to determine the y-intercept

f(0) = 2(3)^0

Evaluate

f(0) = 2

This means that the y-intercept of f(x) = 2(3)^x is (0,2)
