Answer:
linear equation in the point-slope form
Step-by-step explanation:
There are many forms an equation for a line may take. Some of the ones commonly seen are ...
ax +by = c . . . . standard form (a,b,c mutually prime integers; a>0)
y = mx + b . . . . slope-intercept form (m=slope; b=y-intercept)
y -k = m(x -h) . . . . point-slope form (m=slope, (h, k)=point)
__
and some additional ones I commonly use are ...
x/(x-intercept) +y/(y-intercept) = 1
y = m(x -h) +k . . . . variation of point-slope form (m=slope; (h, k)=point)
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . two-point form (points (x1, y1) and (x2, y2))
bx -ay = bh-ak . . . . line perpendicular to standard form line ax +by = c through point (h, k)
__
If you compare these forms to the equation you're given, you see it matches the "point-slope form" for point (4, 2) and slope 7.

What is the measure of \greenD{\angle x}∠xstart color #1fab54, angle, x, end color #1fab54?
Angles are not necessarily drawn to scale.Given the following:
Answer:
<x = 31°
Step-by-step explanation:
m<BCA = m<GCJ (vertical angles)
m<BCA = 59° (substitution)
Since line KL is perpendicular to line FG, the angle formed at point B is 90°.
Therefore, m<ABC = 90°
m<BAC + m<ABC + m<BCA = 180° (sum of triangle)
m<BAC + 90° + 59° = 180° (Substitution)
m<BAC + 149° = 180°
m<BAC = 180° - 149°
m<BAC = 31°
<x = <BAC (vertical angles)
m<x = 31° (substitution)

Solve the proportion 100/x=75/6
Answer: x=8.
Step-by-step explanation: Here are the steps to solving this proportion:
100/x=75/6.
Step 1: Cross-multiply.
100/ x = 75 /6
(100)*(6)=75*x
600=75x
Step 2: Flip the equation.
75x=600
Step 3: Divide both sides by 75.
75x
75
=
600
75
x=8
So the answer is x=8.

Mitchell’s dog is 1/3 as old as Katie’s cat. The sum of their ages is 12 years. How old is Mitchell’s dog?
Answer:
Mitchell's dog is 3 years old
Step-by-step explanation:
9 x 1/3 = 3
9 + 3 = 12
To solve this I just thought of the multiples of three under 12 that if added to 3 are equal to 12 to find Katie's cat age. The multiples of three under 12 are 3, 6 and 9. It couldn't be 3 and 6+3=9 so it had to be 9. So if Katie's cat is 9, you just multiply 9 by 1/3 or divide it by 3 to find Mitchell's dog age.
One batch of brownies calls for 1 box of brownie mix and the ingredients shown below. What amount of eggs, water, and oil would you need for 2 batches of fudge-like brownies?
Group of answer choices
4 eggs, 1/8 cup water, 1/4 cup oil
4 eggs, 1/2 cup water, 1 cup oil
6 eggs, 1/2 cup water, 1 cup oil
6 eggs, 1/4 cup water, 1/2 cup oil
Answer:
4 eggs, 1/2 cup water, 1 cup oil.
Step-by-step explanation:
The brownie mix requires eggs and water to be mixed with the packet mixture to form a paste like substance and then heat the mixture in the oven or microwave. Two batches of fudge like brownie will require 4 eggs and half cup of water. If more eggs are mixed then the fudge substance will be reduced and the cake will be formed.

Use the given x and y values to write a direct variation equation
x=5, y=30
Answer:
The direct variation equation is y = 6x
Step-by-step explanation:
The direct variation equation is y = kx, where
k is the constant of variationTo find the value of k, use the initial values of x and y
∵ y = 5, y = 30
∵ y = k x
→ Substitute the values of x and y to find k
∵ x = 5 and y = 30
∴ 30 = k (5)
∴ 30 = 5k
→ Divide both sides by 5
∴ [tex]\frac{30}{5}=\frac{5k}{5}[/tex]
∴ 6 = k
→ Substitute it in the form of the equation
∴ y = 6x
The direct variation equation is y = 6x
Which one is the answer ?? Plzz
Answer:
answer is c
Step-by-step explanation:
you have to find x first and try any of the equation if you get y and it is the same of the graph and thats the answer

Answer:
t = 6
Step-by-step explanation:
First, add 13.6 (inverse operation)
18 = 3t (divide by 3)
6 = t
sub in to check
Answer:
t=6
Step-by-step explanation:
4.4=-13.6+3t [add -13.6 to both sides]
18=3t [divide 3 from 18]
t=6

A photo 5 inches wide and 8 inches long is enlarged.
How wide is the new photo if it is (1)12 inches; (2)20 inches; (3)10 inches long?
Step-by-step explanation:
if the new photo is 12 inches long than the photo is enlarged
12/8=3/2
so the new photo is (3/2)*5 =15/2=7.5 inches wide.
Now,about the new photo 20 inches long it means that is enlarged 20/8=5/2 inches
so the new photo is wide 5*(5/2)=25/2=12,5 inches.
The photo 10 inches long is enlarged 10/8=5/4 inches.So the new photo is 5*(5/4)=25/4=6,25 inches wide.

Find the sum of -9X + 13 and -16x - 6
A.-25x +7
B. 25x -7
C.-25x-7
D.25x+7
Answer:
A. -25x + 7
Step-by-step explanation:
First, to answer this question, we will combine the two sides of the equation:
(-9x + 13) + (-16x - 6)
Now, we take away the parentheses and add like terms:
-9x + 13 + -16x - 6 =
-25x + 7
So, the answer would be A. -25x + 7

How much tax would you pay on an item at 5% tax rate costing $75? (Round to the nearest cent)
Answer:
3.75
Step-by-step explanation:
Answer:
$3.75
Step-by-step explanation:
All you are going to do is multiply .05 or 5% by 75.
.05 * 75 = 3.75
(So now you are going to add 3.75 to $75 because the tax is 3.75)
75 + 3.75 = $78.75
(So you would pay $3.75 in tax)

Annie bakes cookies and cupcakes in a ratio of 2 to 7 for her gift boxes. Her school needs 36 desserts to sell in a bake sale. How many cupcakes will she bake? How many cookies will she bake ?
Let's say cookies are 2x. If there are 2x cookies then there are 7x cupcakes. Now, 2x cookies + 7x cupcakes = 36 desserts.
9x = 36
So, x = 4
Now, remember that cookies = 2x. 2x = 2 times 4 = 8.
She will bake 8 cookies.

A theater charges $45 for each general admission ticket and $25 for each same-day ticket. If Dan spent $485 on 13 tickets, how much money did he spend on same-day
tickets?
$225
$200
$125
O $75
Answer:
Step-by-step explanation:
45g + 25s = 485
g + s = 13
45g + 25s = 485
-25g - 25s = -325
20g = 160
g = 8
8 + s = 13
s = 5
25(5)= $125 on same-day tickets
