I need to solve and find x. 4x+15<40
antiseptic1488 [7]

Answer:

x or x< 6 \frac{1}{4}

Step-by-step explanation:

4x + 15 < 40

Subtract 15 from both sides

4x + 15 - 15 < 40 - 15

4x < 25

Divide both sides by 4

4x/4 < 25/4

x < 6.25

or

x < 6 1/4

3/2 (4)^x = 6144
3/2 4^x = 6144
(2/3)3/2 4^x = 6144(2/3)
4^x = 4,096
4^6 = 4,096
4,096 = 4,096

topjm [15]

Answer:

<h2>y = 2x+4</h2>

Step-by-step explanation:

A(-3,-2) and B(1,6).\\\\x_1 = -3\\y_1 = -2\\x_2 = 1\\y_2 =6\\\frac{y-y_1}{x-x_1} =\frac{y_2-y_1}{x_2-x_1} \\\frac{y -(-2)}{x -(-3)} =\frac{6-(-2)}{1-(-3)}\\\frac{y+2}{x+3} = \frac{6+2}{1+3} \\\frac{y+2}{x+3} = \frac{8}{4} \\Cross-multiply\\4(y+2) =8(x+3)\\4y +8 =8x+24\\4y = 8x +24-8\\4y = 8x+16 \\OR\\ y = 2x+4
