Mathematics
1 answer:
Mashutka [201]3 years ago
7 0

Answer:

D and E

Step-by-step explanation:

Given

\sqrt{x} < 9 ( square both sides )

(\sqrt{x} )² < 9², that is

x < 81

The only values where x < 81 are 75 and 80, that is D and E

What type of triangle is formed by joining the points D(7, 3), E(8, 1), and
KiRa [710]

D(7, 3), E(8, 1), and  F(4, -1)

We calculate the squared distances between the points:

DE^2 = 1^2 + 2^2 = 5

EF^2=4^2+2^2=20

DF^2=3^2+4^2=25

Since DF^2=DE^2+EF^2 we have a right triangle with hypotenuse DF.

WHAT THE HECC IS THIS
anyanavicka [17]

Answer:

h(x)

Step-by-step explanation:

to solve for an inverse, you swap the x and the y and then solve for y

f(x) = 4x^3-8

y = 4x^3 - 8

x = 4y^3 - 8   swap the x and y

now solve for y:

x + 8 = 4y^3

(x + 8)/4 = y^3

1/4x + 8/4 = y^3

1/4x + 2 = y^3

y = \sqrt[3]{1/4x + 2}

AlexFokin [52]

Answer:

  1. \huge{x =  -  \frac{5}{4}  +  \frac{7}{4} y}
  2. \huge{x =  -  \frac{7}{3}  +  \frac{2}{3} y}

Step-by-step explanation:

1. 4x - 7y =  - 5

4x =  - 5 + 7y

\boxed{\green{x =  -  \frac{5}{4}  +  \frac{7}{4} y}}

y E R

○○•○○

2. 3x - 2y =  - 7

3x =  - 7 + 2y

\boxed{\green{x =  -  \frac{7}{3}  +  \frac{2}{3} y}}

y E R
