Answer:
Step-by-step explanation:
Write an equation of the line with a slope of −7 and y-intercept of 1.
Answer:
y = -7x + 1
Step-by-step explanation:
Remember the formula for slope-intercept form: y = mx+ b
m is equal to the slope value
b is equal to the y-intercept value
Meaning, when you substitute the values in, you get:
y = -7x + 1
Answer:
y = -7x - 1 is the desired equation.
Step-by-step explanation:
Choose the form of the equation of a straight line that requires the least amount of work. In this particular case we are given the slope (-7) and the y-intercept (1), and so use the slope-intercept form y = mx + b:
y = -7x - 1 is the desired equation.

Step-by-step explanation:
use soh cah toa
1. cos is adjacent/hypotenuse
cos73=x/28
multiply both sides by 28
28cos73=x=8.186
2. sin is opposite over hypotenuse
sin68=x/28
multiply both sides by 28
28sin68=x=25.961
3. sin is opposite over hypotenuse
sin26=x/9
myltiply both sides by 9
9sin26=x=3.945
Which of the following is a true statement about the angles in the figure below?
Answer:
The statement which is true about the angles in the figure is;
The measure of Angle 4 is 137 degrees
Step-by-step explanation:
From the question diagram, we have;
The interior angles of the triangle are;
43°, 56°, and ∠1
Therefore, by the angle sum theorem, we have;
∠1 = 180° - 43° - 56° = 81°
∠1 = 81°
The measure of ∠1 is 81°
By the sum of angles on a straight line, we have;
∠1 + ∠2 = 180°
∴ 81° + ∠2 = 180°
∠2 = 180° - 81° = 99°
The measure of ∠2 is 99°
Similarly, for the angles 56° and ∠3 which are on a straight line, we have;
56° + ∠3 = 180°
∠3 = 180° - 56° = 124°
The measure of ∠3 is 124°
For the angles 43° and ∠4 which are on a straight line, we have;
43° + ∠4 = 180°
∠4 = 180° - 43° = 137°
The measure of ∠4 is 137°
Therefore the true statement is the measure of angle 4 is 137 degrees.

a3 = 18 and a6 = -486
Find a10
Answer:
The value of a₁₀ is -1158
Step-by-step explanation:
a₃ = 18
a₆ = - 486
Now,
a₃ = 18 can be written as
a + 2d = 18 ...(1) and
a₆ = - 486 can be written as
a + 5d = - 486 ...(2)
Now, from equation (2) we get,
a + 5d = - 486
a + 2d + 3d = - 486
18 + 3d = - 486 (.°. a + 2d = 18)
3d = - 486 - 18
3d = - 504
d = - 504 ÷ 3
d = - 168
Now, for the value of a put the value of d = -168 in equation (1)
a + 2d = 18
a + 2(-168) = 18
a - 336 = 18
a = 18 + 336
a = 354
Now, For a₁₀
a₁₀ = a + 9d
a₁₀ = 354 + 9(-168)
a₁₀ = 354 - 1512
a₁₀ = -1158
Thus, The value of a₁₀ is -1158

Rahim was asked to make p the subject of this formula
Q = 5/3 -7
He started his answer as follows
3Q = p - 21 hence p =
Complete Rahim's final answer.
Answer:
p = 63
Step-by-step explanation:
3Q = p - 21
transfer the -21 to the left as the value of Q. Since it was negative, when we transfer it to the left it will turn to poditve so,
3(21) = p
multiply 3 and 21 so 3 multiplied by 21 is equal to,
63 = p, then the answer is p = 63
Given B=45, C=95, & c=5. Find b. This is Laws of Sines
Answer:
b = 3.55 to the nearest hundredth.
Step-by-step explanation:
b / sin B = c / sin C
b / sin 45 = 5 / sin 95
b = 5 sin 45 / sin 95

GEOMETRY HELP PLEASE!! WILL MARK BRAINLEIST!
4
Answer:
5.7 unit
Step-by-step explanation:
From the question,
Applying pythagoras theorem,
a² = b²+c²....................... Equation 1
From the diagram.
a = /QX/, b = /XR/, c = /RQ/
Given: b = /XR/ = 4 units, c = /RQ/ = 4 units.
Substitute these values into equation 1
a² = 4²+4²
a² = 16+16
a² = 32
a = [tex]\sqrt{32}[/tex]
a = 5.7 units
Hence, QX = 5.7 units

One of the measures of a triangle is 30º. If the sum of the other 2 angles is 150º and the differnce their measures is 18º what are the of the unkown angles
Answer: 84° & 66°
Step-by-step explanation:
find our variables...
difference in two unknown angles is 18 so...
Let's use a, b, & c to set up
a=30 b=b c=b-18
150=b+c
150=b+(b-18)
150=2b-18
168=2b
84=b
Use our known b to find c...
c=b-18
c=84-18
c=66
Adding all three up to make sure they give us 180 degrees is a good way to check our work.
a+b+c=
30+84+66=180

x - 4 = -3
Step-by-step explanation:
We need to find x in this question.
x - 4 = -3
So, shifting -4 from one side to another, we get:-
x = -3 + 4
[+4 because the sign changes when we replace the numbers]
x = 4 - 3
x = 1 is the required answer.

joey took a total of 12 pages of notes during 3 hours of class. after attending 4hours of class, how many pages of notes will joey have in his notebook
HELPPP
Answer:
If he kept taking notes at the same pace, he would have 16 pages of notes in his notebook.
Step-by-step explanation:
By dividing the number of pages of notes taken by the time spent taking them, you can find his rate of note-taking, which is 4 pages an hour. By adding another hour of notes, he should have 16 pages of notes. But if this question is asking for 4 more hours, the answer would be 28 pages.

On Tuesday, Lisa spent $35.78 at the
grocery store. Later in the week, she
returned. At the end of the week, she
had spent $96.52 at the grocery
store. How much did Lisa spend on
her second trip?
Answer:
$60.74 on the second trip.
Step-by-step explanation:
Well we know that she spent $35.78 on the first trip.
We DON’T know how much she spent for the second trip so lets put it as “x” for unknown.
We know she spent a TOTAL of $96.52 for those two trips combined.
So we can make a simple equation
35.78+x=96.52
Now solve the equation.
Subtract 35.78 on both sides to isolate the X
35.78-35.78=0
96.52-35.78= 60.74
So if you plug everything in
0+x=60.74
0 is nothing so we can get rid of that
x=60.74

[tex] \underline{ \underline{ \text{QUESTION : }}}[/tex] In the given quadrilateral PQRS, the mid-points of the sides PQ , QR , RS and SP are A , B , C and D respectively. Prove that ABCD is a parallelogram.
Answer:
See Below.
Step-by-step explanation:
We are given that A, B, C, and D are the midpoints of sides PQ, QR, RS, and SP, respectively.
And we want to prove that ABCD is a parallelogram.
By the definition of midpoint, this means that:
[tex]SD\cong DP, \, PA\cong AQ, \, QB\congBR, \, \text{ and } RC\cong CS[/tex]
To prove, we can construct a segment from S to Q to form SQ. This is shown in the first diagram.
By the Midpoint Theorem:
[tex]DA\parallel SQ[/tex]
Similarly:
[tex]CB\parallel SQ[/tex]
By the transitive property for parallel lines:
[tex]DA\parallel CB[/tex]
Likewise, we can do the same for the other pair of sides. We will construct a segment from P to R to form PR. This is shown in the second diagram.
By the Midpoint Theorem:
[tex]AB\parallel PR[/tex]
Similarly:
[tex]DC\parallel PR[/tex]
So:
[tex]AB\parallel DC[/tex]
This yields:
[tex]DA\parallel CB\text{ and } DC\parallel AB[/tex]
By the definition of a parallelogram, it follows that:
[tex]ABCD\text{ is a parallelogram.}[/tex]

Lin’s family needs to travel 325 miles to reach her grandmother’s house.
At 26 miles, what percentage of the trip’s distance have they completed?
How far have they traveled when they have completed 72% of the trip’s distance?
At 377 miles, what percentage of the trip’s distance have they completed?
Answer:
8%, 234 miles , 100%
Step-by-step explanation:
X/100 x 325 = 26, X/100 = 0.08, X = 8%
.
0.72 x 325 = 234 miles
.
3rd i guess the question itself is wrong but answer it by 100%
Answer:
Percentage = 8%
Step-by-step explanation:
At 26 miles, Lin's family completed 8% of the trip’s distance
1. Let's review the information given to us to answer the question correctly:
Distance from Lin's home to her grandmother's house = 325 miles
2. At 26 miles, what percentage of the trip’s distance have they completed?
Percentage = Distance covered/Total distance * 100
Replacing with the values we know:
Percentage = 26/325 * 100
Percentage = 0.08 * 100
Percentage = 8%
