M= (7-1)/(2-0)=3
y=3x + c
plug in Q 
1= 3 x 0 +c
=> c =-2
=> the equation represents line QR is y=3x -2

y – 1 = 3x

since Q is (0,1) that would make 1 the y-intercept.

using a formula to find the slope we end up with 3.

1 is a negative because when moved to the other side it must be positive.

9w-4w+6<1+5w supposed to combine like terms
Mariana [72]

Answer/Step-by-step explanation:

Given:

9w - 4w + 6 < 1 + 5w

To solve, collect like terms.

Subtract 5w from both sides

9w - 4w + 6 - 5w < 1 + 5w - 5w

9w - 4w - 5w + 6 < 1

6 < 1 (incorrect)

The inequality given has no solution or an information is missing.

HELP ME PLEASE <br> solve the right triangle
Amiraneli [1.4K]

ST = 7.2

RT = 4.04

m∠S = 34°

Solution:

Given ΔRST is a right triangle.

RS = 6, ∠T = 56°

$\csc A=\frac{\text {Hypotenuse} }{\text {Opposite side}}

$\csc A=\frac{ST}{RS}

$\csc 56^\circ=\frac{ST}{6}

$\csc 56^\circ \times 6=ST

1.206 × 6 = ST

7.236 = ST

ST = 7.2

$\cot A=\frac{\text {Adjacent side} }{\text {Opposite side}}

$\cot A=\frac{RT}{RS}

$\cot 56^\circ=\frac{RT}{6}

$\cot 56^\circ \times 6=RT

0.674 × 6 = RT

4.044 = RT

RT = 4.04

To find the measure of angle S.

Sum of the interior angles of the triangle = 180°

m∠R + m∠S + m∠T = 180°

90° + m∠S + 56° = 180°

m∠S + 146° = 180°

m∠S = 180° – 146°

m∠S = 34°
