9y-8x=63 How do I convert this into slope-intercept form?
Answer:
turn it into y=mx+b
Step-by-step explanation:
get y alone
add 8x to both sides
9y=63+8x
divide both sides by 9
63/9=7 8x/9= [tex]\frac{8x}{9}[/tex]
simplify
y=[tex]\frac{8}{9}[/tex]x+7Answer:
y = 0.8x + 7 or
y = [tex]\frac{4}{5}[/tex]x + 7
Step-by-step explanation:
The slope intercept formula is: y = mx + b
9y - 8x = 63
+8x +8x
= 9y = 63 + 8x
9y/9 = 63/9 + 8x/9 ←
We're getting rid of the 9 beside the y, so we have to divde every number by 9.
= y = 0.8x + 7 if you want the 0.8 as a fraction, it'll be [tex]\frac{4}{5}[/tex]

Answer:
50 degrees
Step-by-step explanation:
You can see that angle ADC is composed of angle ADB and angle BDC
Angle ADB is 38 degrees and angle BDC is 12 degrees
Therefore angle ADC is 50 degrees
Angle ADC is opposite from angle ABC so they are congruent.
So angle ABC is 50 degrees

Write an equation in slope-intercept form for a line with a slope of -2 and a 8 points
y-intercept of 7. *
Answer:
y=-2x+7
Step-by-step explanation:
slope intercept form is equal to y=mx+c
where y is the y value
x is the x value
m is the gradient
and c is the y intercept
so the equation for this set of values is equal to
y=-2x+7
slope will be the m
and b is the y intercept
y＝mx＋b
y＝-2x＋7

Find the measure of each missing angle. Subject: Geometry
Unit 5: Relationships in Triangles
Homework 1: Triangle Midsegments
Answer:
Q10
∠1 = ∠5 = 180° - 144° = 36°∠2 = 56°∠3 = 180° - 56° = 124°∠4 = 144° - 56° = 88°∠5 = ∠1 = 36°Q11
∠1 = 35°∠2 = 180° - 35° = 145°∠3 = 90° - 35° = 55°∠4 = 180° - ∠5 = 180° - ∠3 = 180° - 55° = 125°∠5 = ∠3 = 55°Measure of angles for figure 1:
∠1=36∠2=56∠3=124∠4=88∠5=36Measure of angles for figure 2:
∠1=35∠2=145∠3=55∠4=125∠5=55The angle is formed by two rays at a common point of the two rays.
For given figure 1:
∠1+144=180 (Sum of angles on same side of transversal is 180°)
∠1=180-144
∠1=36
∠5+144=180(Sum of angles on a line is 180°)
∠5=180-144
∠5=36
Similarly, ∠3=180-56
∠3=124
∠4+36+56=180(Sum of all angles of a triangle is 180°)
∠4=180-36-56
∠4=88
∠2+36+88=180
∠2=56
Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.
For given, figure 2:
∠1=35(Alternate angle on same side of transversal are equal)
∠2=180-35
∠5=180-35-90(Sum of all angles of a triangle is 180°)
∠5=55
∠4+55=180(Sum of angles on a line is 180°)
∠4=180-55
∠4=125
Similarly, ∠2=180-35(Sum of angles on a line is 180°)
∠2=145
∠3=180-35-90(Sum of all angles of a triangle is 180°)
∠3=55
Thus, measure of angles for figure 2 are ∠1=35, ∠2=145, ∠3=55, ∠4=125, ∠5=55

Answer:
11. 35 ft²
12. 24 cm²
13. 18 ft²
14. 28 in²
15. 9 in²
Step-by-step explanation:
11. A= (b×h)÷2
= (10×7)÷2
= 70 ÷ 2
= 35 ft²
12. A= (b×h)÷2
= (8×6)÷2
= 48 ÷ 2
= 24 cm²
13. A=(b×h)÷2
=(9×4)÷2
= 36 ÷ 2
= 18 ft²
14. A=(b×h)÷2
=(7×8)÷2
= 56 ÷ 2
= 28 in²
15. A=(b×h)÷2
=(3×6)÷2
= 18 ÷ 2
= 9 in²
