Heyo! I need some help, please. What is the x coordinate if (x, 17) is on a line that passes through the points (1, 2) and (-1, -8) on a standard (x, y) coordinate plane?
Answer:
x = 4Step-by-step explanation:
The line with points (1,2) and (-1,-8). Work out its equation.
y = mx + bThe slope is:
m = (-8 - 2)/(-1 - 1) = -10/-2 = 5To find the y intercept, substitute x and y-xoordinates of point (1,2):
2 = 5(1) + b b = 2 - 5b = -3The line is:
y = 5x - 3Point (x, 17), substitute y-coordinate and solve for x
17 = 5x - 35x = 17 + 35x = 20x = 20/5x = 4R950 is divided between Ann, Jill, Agnes Ann gets R100 more than Jill, Jill gets R50 more than Agnes. How much did Agnes get

Answer:
90 degrees
Step-by-step explanation:
classmate is muy stupio
the non 90 degree angles are all congruent
which means each of them are 45 degrees
cuz triangle degree add up to 180
then
u use subtraction
cuz a line is 180 degrees
Half of $1\%$ of $40$ is one less than what number? Express your answer as a decimal to the nearest tenth.
Answer:
$0.2
Step-by-step explanation:
1% of $40
1/100 * 40
0.01 * 40 = $0.4
Half of $0.4
$0.4 / 2 = 0.2
Therefore, half of 1% of $40 equals $0.2

2x - 5y = - 15
I need to rewrite it in the terms of “y” an I need the steps on how to do it thanks
Answer:
2x+15=5y
y=(2x+15)/5
hope this helps
Answer:
[tex]y = \frac{2}{5} x + 3[/tex]
Step-by-step explanation:
2x - 5y = -15
Firstly, you will need to isolate the variable you are solving for, in this case, y.
2x - 2x - 5y = -15 - 2x
-5y = -15 - 2x
-5y/-5 = -15/-5 - 2x/-5
A negative divided or multiplied by a negative is positive.
[tex]y = 3 + \frac{2}{5} x[/tex]
Rearrange.
[tex]y = \frac{2}{5} x +3[/tex]
Triangle A C B is a right triangle. Angle C A B is 90 degrees, angle A B C is (4 x) degrees, and angle A C B is (7 x minus 20) degrees. What is the m∠ACB? 10° 50° 90° 180°
Answer:
50°
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees
Hence given that in a triangle ACB with angles 90°, 4x°, 7x - 20
As such
90 + 4x + 7x -20 = 180
simplify
11x + 70 = 180
11x = 180 - 70
11x = 110
Divide both sides by 11
x = 110/11
x = 10
m∠ACB is 7x - 20
Substitute the value of x into the expression
= 7(10) - 20
= 70 - 20
= 50
Answer:
The answer is 50 degrees

Number line graph with open circle on 24 and shading to the right.
Number line graph with closed circle on 24 and shading to the right.
Number line graph with open circles on 0 and 24 and shading in between.
Number line graph with closed circles on 0 and 24 and shading in between.
Answer:
Number line graph with closed circle on 24 and shading to the right.
Step-by-step explanation:
First, the graph has to have a closed circle on only 24.
Since she has $61 and needs at least $85 to buy a skateboard, she needs to have at least $24 saved to buy one.
This means the last 2 answer choices are wrong, because there cannot be shading in between.
The first answer choice is also wrong because it puts a open circle, instead of a closed one, on 24.
So, the correct answer is Number line graph with closed circle on 24 and shading to the right.

Answer:

Step-by-step explanation:
The points form a right triangle. The circumcenter is the midpoint of the hypotenuse of a right triangle. Here, that is the midpoint of AC:
O = (A +C)/2
O = ((1, 1) +(10, 8))/2 = (11, 9)/2 = (5.5, 4.5)
The circumcenter is (5.5, 4.5).

Carl is deriving the quadratic equation by completing the square. His work at one of the steps is shown. x + b/na = + or - b^2-4ac. Carl is not sure what the value of n is. What value should he use to continue deriving the quadratic equation correctly? A. 1 B. 2 C. 3 D. 4
Answer:
the correct option is B. 2
Step-by-step explanation:
As given,
x + [tex]\frac{b}{na}[/tex] = ± √b²-4ac
⇒x = -[tex]\frac{b}{na}[/tex] ± √b²-4ac
As e know that the quadratic formula is
x = [tex]\frac{-b + or - \sqrt{b^{2} - 4ac } }{2a}[/tex]
So , by comparing with the formula
we get
n = 2
So, the correct option is B. 2

the sum of three consecutive even numbers is 78,find the number
Answer:
24, 26, 28
Step-by-step explanation:
The final number is 78
first we can divide 78/3= 26
so 26+26+26= 78
we can leave the middle 26 but we can give 2 from the first number to the last number
24+26+28=78

Find the roots of the equation: f(x)=64x2+6=31
Answer:
5/8, -5/8
Step-by-step explanation:
64x^2 = 25
divide both sides by 64
x^2 = 25/64
take the square root of both sides, and the negative square roots
Answer:
x = 5/8=0.625 and x = -5/8=−0.625
Step-by-step explanation:
f(x)=64x^2+6=31
Subtract 6 from both sides.
64x^2+6=31
Subtract 6 from 31 to get 25.
64x^2=25
Divide both sides by 64.
x^2=25/64
Take the square root of both sides of the equation.
x=5/8=0.625
x=-5/8=−0.625

Answer:
Left: yes it is linear
Right: No it is not.
Step-by-step explanation:
Left Problem
The table on the left is linear. It's general form is
y = 6x + 7
x = 5
y = 5*6 + 7
y = 37
-------------------
x = 8
y = 6*8 + 7
y = 48 + 7
y = 55
------------------
y = 6*12 + 7
y = 72 + 7
y = 79
=============
Right Problem
The right problem looks like it is linear. It is not, I don't think. Do the same thing you did above.
y = 62x
x = 2
y = 2*62
y = 124
-----------------------
y = 62x
x = 6
y = 62 * 6
y = 372
---------------------
y = 62*x
x = 9
y = 62 * 9
y = 558
It should be 558 not 552
