y=2x y=7x + 15 substitution
Answer:
y = -6 and x = -3
Step-by-step explanation:
Data :
Eq 1 : y = 2x
Eq 2 : y = 7x + 15
So
Take eq 1 and solve for x
⇒ x = y/2 eq 3
Put eq 3 in eq 2
y =7 (y/2) + 15
y - 7y/2 = 15
( 2y-7y )/2 = 15
-5y/2 = 15
-5y =30
y = -6
And put value of y in eq 3 to find x
x = -6/2
x =-3
What is the distance between (-1,5) and (2,9)
Answer:
5 units
Step-by-step explanation:
To find the distance between two points on a graph, we use the distance formula [tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2[/tex] where [tex]d[/tex] is the distance between points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].
For this problem, we will identify [tex](x_1,y_1)\rightarrow(-1,5)[/tex] and [tex](x_2,y_2)\rightarrow(2,9)[/tex]:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(9-5)^2+(2-(-1))^2}\\\\d=\sqrt{(4)^2+(3)^2}\\\\d=\sqrt{16+9}\\\\d=\sqrt{25}\\\\d=5[/tex]
Therefore, the distance between [tex](-1,5)[/tex] and [tex](2,9)[/tex] is 5 units

i don’t really know how to picture what the graph of the derivative would look like
Answer:
A) f'(3) < f'(0) < f'(-2)
Step-by-step explanation:
You don't need to create a graph of the derivative. Remember that the derivative is the slope/rate of change of a function at a certain point!
At f(-2), you can see that the function is increasing around it, which suggests that f'(-2) is positive.
At f(0), you can see that the function doesn't increase nor decrease around it, which suggests that f'(0) is 0 (or no slope!).
At f(3), you can see that the function is decreasing around it, which suggests that f'(3) is negative.
This must mean that f'(3) < f'(0) < f'(-2)
I hope this clears things up, and please ask questions in the comments if you are still confused! I want to help you!
Jerry, a plumber, charges an initial fee of $75, plus $65 per hour. Which represents the cost of hiring Jerry for 6 hours?
Answer:
The cost of hiring Jerry for 6 hours would be $475.
Step-by-step explanation:
All you really have to do to get this answer is multiply 65 by 6, and then add 75 on to that.
65 x 5 = 390
390 + 75 = 465
Hope I helped!
Answer:
465
Step-by-step explanation:
Cost = ($65 x h) + $75
H= Hours
65 x 6= 390
390+ 75= 465
Which of the following gives the area, A, of a circle with a diameter of 6? A A=π(3) B A=π×2(3) C A=π(3)2 D A=π×2(3)2
Answer:
C
Step-by-step explanation:
the area (A) of a circle is calculated as
A = πr² ( r is the radius )
here diameter = 6 , then r = 6 ÷ 2 = 3 , so
A = π(3)² → C
Which system of equations below has infinitely many solutions? y = –3x 4 and y = –3x – 4 y = –3x 4 and 3y = –9x 12 y = –3x 4 and y = Negative one-thirdx 4 y = –3x 4 and y = –6x 8.
the equations y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions. option B is correct.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

If [tex]\rm \dfrac{a}{d} = \dfrac{b}{e} = \dfrac{c}{f}[/tex] then lines have infinitely many solutions.
Which system of equations below has infinitely many solutions?y = –3x + 4 and 3y = –9x + 12
On comparing we have
a = -3 , b = 1, and c = 4
d = -9 , e = 3, and f = 12
Then their ratio will be
[tex]\rm \dfrac{1}{3} = \dfrac{-3}{-9} = \dfrac{4}{12}\\\\\rm \dfrac{1}{3} = \dfrac{1}{3} = \dfrac{1}{3}[/tex]
Hence y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions.
Thus the option B is correct.

One soulution contains 2 parts salt to 8 parts water, and another contains 3 parts salt to 5 parts water. How much of each should be mixed together in order to obtain 280 quarts of a soulution that is 3 parts salt to 7 parts water?
PLS HELP!!!!
Answer:
120
Step-by-step explanation:
Given,
Solution A contains 2 parts salt to 8 parts water
Solution B contains 3 parts salt to 5 parts water
Target Mixture contains3 parts salt to 7 parts water:
Expressing the salt concentration in decimal form
Solution A: 2/(2 + 8) = 2/10 = 0.20 salt
Solution B: 3/(3 + 5) = 3/8 = 0.375 salt
Mixed Solution: s/(3 + 7) = 3/10 = 0.30 salt
Since target mixture is 280 quarts
If the amount of 0.375 salt present in mixed solution = x
Then, the amount of 0.20 salt, y = 280 – x
Using a typical mixture equation
0.375x + 0.20(280-x) = 0.30(280)
0.375x + 56 - 0.20x = 84
Subtract 56 from both sides of the equation
0.375x - 0.20x + 56 – 56 = 84 – 56
0.375x - 0.20x = 28
0.175x = 28
Divide both sides of the equation by 0.175
0.175x/0.175 = 28/0.175
x = 160
y = 280 – x
y = 280 – 160
y = 120

First, determine the value of x. Then find the measure of ∠BCA. Will brainlist first correct answer.
X=_________
Answer:
x = 16° || ∠BCA = 57°
explanation:
All the angles lie on a straight line.
A triangles total interior angle is 180°
So we need to find the inner angle of each side and they are:
∠ABC = 180 - ( 5x + 12 )∠BCA = 180 - ( 10x - 37 )∠CAB = 180 - ( 9x + 1 )So with this:
180 - ( 5x + 12 ) + 180 - ( 10x - 37 ) + 180 - ( 9x + 1 ) = 180
180 - 5x - 12 + 180 -10x +37 + 180 -9x-9 = 180
564 - 24x = 180
-24x = 180 - 564
-24x = -384
x = 16°
Then ∠BCA = 180 - ( 10x - 37 )
= 180 - ( 10 * 16 - 37)
= 57°

Find the distance between (6,4) and (0,-5)
Step-by-step explanation:
we know,
distance = √(x_2 - x_1)² + (y_2 - y_1)²
given points
(6,4) and (0,-5)
according to formula
→ d = √(0 - 6)² + (-5 - 4)²
→ √(-6)² + (-9)²
→ √36 + 81
→ √117 = 10.81 (approx.)
therefore, distance between both the points are 10.81 (approx.).

The given ratios are not proportional.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
The given fractions are 0.2/2.6 and 0.3/3.6
Here, 0.2/2.6 =2/26
= 1/13
Now, 0.3/3.6 =3/36
= 1/12

Using what you know about angles and translations, find all of the angle
measures in the image below.
Answer:
∠1=135°

∠3=45°
∠4=135°
∠5=135°
∠6=45°
∠7=45°
∠8=135°
Step-by-step explanation:
→∠1=∠4[Being vertically opposite angles]
→∠4=135°
→∠1=∠5[Corresponding angles]
→∠5=135°
→∠5=∠8[Being vertically opposite angles]
→∠8=135°
→∠1+∠2=180°[Sum of linear pair]
→∠2=180°-135°
→∠2=45°
→∠2=∠3[Being vertically opposite angles]
→∠3=45°
→∠3=∠6[Alternate angles]
→∠6=45°
→∠6=∠7[Being vertically opposite angles]
→∠7=45°
Answer:
∠1 = 135°
∠2 = 45°
∠3 = 45°
∠4 = 135°
∠5 = 135°
∠6 = 45°
∠7 = 45°
∠8 = 135°
Step-by-step explanation:
The diagram shows two lines that are intersected by a transversal. (A transversal is a line that passes through two lines in the same plane at two distinct points).When two lines are intersected by a transversal, the angles in matching corners are called Corresponding AnglesUsing the Angles on a Straight Line theorem
Angle 1 and 2 are on a straight line, so
∠2 = 180 - ∠1 = 180 - 135 = 45°
Similarly,
∠3 = 180 - ∠1 = 180 - 135 = 45°
∠4 = 180 - ∠3 = 180 - 45 = 135°
Using the Corresponding Angles theorem
As ∠1 = ∠5, then ∠5 = 135°
As ∠2 = ∠6, then ∠6 = 45°
As ∠3 = ∠7, then ∠7 = 45°
As ∠4 = ∠8, then ∠8 = 135°

Step-by-step explanation:
So the whole cake is 1/1.
She gives half of it to her mom so now she has 1/2.
She eats 1/4 of the remaining cake. 1/4 of 1/2 is 1/8. 1/2=4/8. Now she has 3/8.
She cuts the rest in half. 3/8 = 6/16. Half of 6/16 is 3/16
