Write the equation of the line parallel to y = 3x + 3, that passes through (-3, 10).
y=3x+19
Step-by-step explanation:
equation parallel to y=3x+3 means having the same gradient .Here gradient is 3 where you equate equation with y=mx +c where m is the gradient and c is the y-intercept
Equation of line y=3x+c
you must find c ,replace point (-3,10) in equation y=3x+c
10=3(-3)+c
10=-9+c
10+9=c
c=19
equation of line parallel to y=3x+3 that passes through(-3,10) is y=3x+19

Brett bought 2 shirts. One cost $4 more than 3 times the other. Together, the 2 shirts cost
him $72.
HELP PLEASE.
Answer:
one costs 17 dollars the other costs 55 dollars
Step-by-step explanation:
we have to make 2 equations using variables
x=shirt 1
y= shirt 2
y+x=72
x=3y+4
then substitute 3y+4 for x in the first equation
y+3y+4=72
subtract 4 and add y and 3y
4y=68
divide by 4
y= 17
use this for y in the second equation
x=3(17)+4
x=51+4
x=55
How do you solve problems involving sequence? Discuss the mathematics concepts and principles applied when solving problems involving sequence
Step-by-step explanation:
Sequence is defined as arrangement f numbers in a specific or defined pattern. Sequence are categorized into
1) Arithmetic
2) Geometric
Arithmetic sequence are characterized by their common difference while Geometric sequence are characterized by their common ratio.
Given a sequance of numbers say;
T1, T2, T3...
The first term "a" of the sequence is T1
Common difference d = T2-T1 =T3-T2
Common ratio = T2/T1 = T3/T2
The formula for calculating nth term of an Arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
The nth term of a Geometric sequence is expressed as;
Tn = ar^{n-1}
r is the common ratio
Numbers are arranged in a sequence when they follow a predetermined or established pattern. Sequences can be divided into
1) Mathematics
2) Graphitic
Geometric sequences are characterized by their common ratio, whereas arithmetic sequences are distinguished by their common difference.
Suppose a sequence of numbers is given;
T1, T2, T3...
The sequence's initial term "a" is T1.
common distinction d = T2-T1 =T3-T2
T2/T1 Common Ratio T3/T2
The following is the formula for finding the nth term in an arithmetic sequence:
Tn = a+(n-1)d
The first term is a.
The number of terms is n.
d is the typical discrepancy
The nth term of a Geometric sequence is expressed as;
[tex]T_{n} =ar^{n-1}[/tex]
r is the common ratio

Answer:
Given are two complex numbers as
When we add algebraically, we add the real parts and then add the imaginary parts separately
Hence
Geometrically we draw position vector of both the points. The sum would be resultant of these two vectors.
Step-by-step explanation:
The sum of the complex number in rectangular form is -1 +i
Sum of complex numberComplex numbers are written in the form x + iy
Given the complex numbers expressed as:
z1 = 8 - i
z2 = -9 + 2i
Take the sum
z1 + z2 = (8 - 9) + (-i+2i)
z1 +z2 = -1 + i

When a baseball is hit by a batter the height of the ball age of T at time TT equals zero is determined by the equation age of T equals -16 T squared +64 2+ 4FT is in seconds for which interval of time is the height of the bar greater than or equal to 52 feet
Answer:
1 ≥ t ≤ 3
Step-by-step explanation:
Given
h(t) = -16t² + 64t + 4
Required
Determine the interval which the bar is at a height greater than or equal to 52ft
This implies that
h(t) ≥ 52
Substitute -16t² + 64t + 4 for h(t)
-16t² + 64t + 4 ≥ 52
Collect like terms
-16t² + 64t + 4 - 52 ≥ 0
-16t² + 64t - 48 ≥ 0
Divide through by 16
-t² + 4t - 3 ≥ 0
Multiply through by -1
t² - 4t + 3 ≤ 0
t² - 3t - t + 3 ≤ 0
t(t - 3) -1(t - 3) ≤ 0
(t - 1)(t - 3) ≤ 0
t - 1 ≤ 0 or t - 3 ≤ 0
t ≤ 1 or t ≤ 3
Rewrite as:
1 ≥ t or t ≤ 3
Combine inequality
1 ≥ t ≤ 3
Derrick is placing a right triangle in the coordinate plane. He knows that the longer leg is 3 times the length of the shorter leg. He places the longer leg on the x-axis.
What coordinates should he assign to the third vertex of the triangle?
Answer:
Longer leg is placed on X axis.
Let the longer leg be at A(0,0) and B(3 a,0),or (-3 a,0), which is either base or altitude.
AB= 3 a
As longer leg = 3 × shorter leg
Shorter leg should be placed either at (0,a) or (0,-a) maintaining triangle as right angled triangle.

The question is in the picture below....
Answer:
The measure of the indicated exterior angle is 110°
Step-by-step explanation:
Let us revise the rule of the exterior angle
In a triangle, the measure of an exterior angle at a vertex of the triangle equals the sum of the measures of the two opposite interior angles to this vertex.
We will use this rule to solve the question
∵ The ladder, the house, and the ground formed a right triangle
∵ The ladder's angle with the ground facing away from the house is
an exterior angle of the triangle
∵ The angles of measures 90° and 20° are its opposite interior angles
→ By using the rule above
∴ The measure of the exterior angle = 90° + 20°
∴ The measure of the exterior angle = 110°
∴ The measure of the ladder's angle with the ground facing away
from the house is 110°
∴ The measure of the indicated exterior angle is 110°

The sword maker in the cove ordered a special tape to wrap the sword handles with. He knew each sword would need 48 inches of tape. If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords? How much will he have left over or how much more will he need?
Answer:
a) If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords?
No he would not
b) How much will he have left over or how much more will he need?
= He would have 144 inches left over.
Step-by-step explanation:
The sword maker in the cove ordered a special tape to wrap the sword handles with. He knew each sword would need 48 inches of tape. If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords? How much will he have left over or how much more will he need?
From the above question, each sword would need 48 inches of tape
He would need to wrap 28 swords, hence:
1 swords = 48 inches
28 swords = x
x = 28 × 48 inches
= 1344 inches of tapes
Therefore to cover each sword he would need a total of 1344 inches of tape.
He ordered 100 feet of tape
We convert 100 feet to inches
1 foot = 12 inches
100 feet = x
x = 100 × 12 inches
x = 1200 inches
Hence, he ordered 1200 inches of tape.
a) If he ordered 100 feet of tape, will he have enough tape to wrap 28 swords?
100 feet = 1200 inches of tapes
To wrap 28 swords he would need 1344 inches of tape hence, he would not have enough tape to wrap 28 swords.
b) How much will he have left over or how much more will he need?
= 1344 inches - 1200 inches
= 144 inches
He would have 144 inches left over.
The graph shows a line and two similar triangles. On a coordinate plane, a line goes through (0, 3) and (6, 11). A small triangle has a rise of 4 and run of 3. What is the equation of the line? y = 3 x + 3 y = three-fourths x + 3 y = four-thirds x + 3 y = 4 x + 3
Answer:
i think that the answer is the first equation
Step-by-step explanation:
The equation of the line passing through the points (0, 3) and (6, 11) is:
y = (4/3)x + 3.
Option C is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
To find the equation of the line passing through the points (0, 3) and (6, 11).
We can use the slope-intercept form of a linear equation,
which is y = mx + b, where m is the slope of the line and b is the y-intercept.
First, we can find the slope of the line by using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
where
[tex](x_1, y_1) = (0, 3)\\(x_2, y_2) = (6, 11).[/tex]
So,
m = (11 - 3) / (6 - 0) = 8/6 = 4/3
The slope of the line is 4/3.
Next,
We can use the point-slope form of a linear equation to write the equation of the line in terms of one of the points and the slope:
[tex]y - y_1 = m(x - x_1)[/tex]
Choosing the point (0, 3), we get:
y - 3 = (4/3)(x - 0)
Simplifying and solving for y, we get:
y = (4/3)x + 3
Therefore,
The equation of the line passing through the points (0, 3) and (6, 11) is:
y = (4/3)x + 3.

Answer:
y=2x-5
Step-by-step explanation:

[tex]x_{1}=0, y_{1}=-5\\[/tex], and m=2
[tex]y-(-5)=2(x-0)[/tex], -(-5)-Two negatives make it positive, and you distribute the 2
[tex]y+5=2x[/tex], you now subtract 5 to get y by itself to get your answer of

80 degrees
Answer:
50
Step-by-step explanation:
Answer:
∠ 2 = 50°
Step-by-step explanation:
5x + 55 and 2x + 100 are corresponding angles and are congruent, thus
5x + 55 = 2x + 100 ( subtract 2x from both sides )
3x + 55 = 100 ( subtract 55 from both sides )
3x = 45 ( divide both sides by 3 )
x = 15
Then
5x + 55 = 5(15) + 55 = 75 + 55 = 130°
5x + 55 and ∠ 2 are adjacent angles and are supplementary, thus
∠ 2 = 180° - 130° = 50°
