Answer:
.
Step-by-step explanation:
2.
If angle A = 4x + 12 and x is given as 15 we can say that angle A is an acute triangle because its measure is less than 90° ➡ 4 × 15 + 12 = 72°
3.
if the angle BAM is a right triangle then
4x + 22 = 90 subtract 22 from the both sides
4x = 68 divide both sides by 4
x = 17

Step-by-step explanation:
<u>Step 1: Define</u>
-4x + 3y = -2
y = x - 1
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -4x + 3(x - 1) = -2
- [Distributive Property] Distribute 3: -4x + 3x - 3 = -2
- Combine like terms: -x - 3 = -2
- [Addition Property of Equality] Add 3 on both sides: -x = 1
- [Division Property of Equality] Divide -1 on both sides: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em> [Original Equation]: y = -1 - 1
- Subtract: y = -2

Answer:
y= -2/3 x - 9
Step-by-step explanation:
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -2/3 x+b
We have a point to substitute into the equation
-5 = -2/3(-6) +b
-5 = 4 +b
Subtract 4 from each side
-5-4 = 4-4+b
-9 = b
y= -2/3 x - 9
