What is the equation that represents the line that passes through the points (9, -2) and (12, -5)?
Hi there!
[tex]\large\boxed{y = -x + 7}[/tex]
To begin, we must use the slope formula to calculate the slope of the line:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the coordinates:
[tex]m = \frac{-5-(-2)}{12-9}[/tex]
Simplify:
[tex]m = \frac{-3}{3} =-1[/tex]
Recall that the equation for a line in point-slope form is:
y - y1 = m(x - x1)
Plug in coordinates into the equation along with the slope:
y - (-2) = -1(x - 9)
Simplify:
y + 2 = -x + 9
y = -x + 7
explain the differnce between -3^4 and (-3)^4
Answer:
[tex] { - 3}^{4} = - (3 \times 3 \times 3 \times 3) \\ {( - 3)}^{4} = ( - 3 \times - 3 \times - 3 \times - 3)[/tex]
The difference is that (-3)^4 has a negative 3 with parenthesis around it, which means that if it was in PEMDAS, you would work that out first.
If a box has a length of 12 inches, a width of 10 inches and a height of 6 inches, what is the surface area?
Answer:
The answer is 28.
Step-by-step explanation:
Add all of them.
(L/ length) 12.
(W/ width) 10
(H/ height) 6
12 + 10 + 6 = 28
I hope this helps
Answer:
504 inches
Step-by-step explanation:
2(lb+hb+hl)
length = 12
height = 6
width = 10
2 (120 + 60+ 72)
2( 252
= 504
pleaseee helppp mee :/
Answer:
vertical,47
Step-by-step explanation:
they are not right next to each other they are across so that is vertical and vertical angles are equal so the second option is correct
Answer:
Vertical; 47
Step-by-step explanation:
The two angles are vertical since they are opposite to each other. Vertical angles are equal therefore, x equals 47° as well.
Factor 5x^2 + 16x – 16
Answer:
(x + 4)(5x - 4)
Step-by-step explanation:
[tex]5x^2 + 16x – 16 \\ = 5x^2 + 20x - 4x– 16 \\ = 5x(x + 4) - 4(x + 4) \\ = (x + 4)(5x - 4)[/tex]
Answer:
(5x - 4) • (x + 4)
Step-by-step explanation:
Multiply the coefficient of the first term by the constant 5 • -16 = -80
Find two factors of -80 whose sum equals the coefficient of the middle term, which is 16 .
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 20
5x2 - 4x + 20x - 16
Add up the first 2 terms, pulling out like factors :
x • (5x-4)
Add up the last 2 terms, pulling out common factors :
4 • (5x-4)
Add up the four terms of step 4 :
(x+4) • (5x-4)
Which is the desired factorization

when a number is doubled and then eight added it became 60 what is the number
Answer:
26
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
Let the number be x.
Now,
2x + 8 = 60
2x = 60 - 8
x = [tex]\dfrac{52}{2}[/tex]
x = 26
Hence, the number is 26.

can someone pls help
Answer: i think the answer 12
Step-by-step explanation:
Answer:
Hello! answer: 20
Step-by-step explanation:
I don't know why they say z = something there is no z so we dont need that but we do need to know what y and x is so... y = 5 and x = 10
so the 10 + 2 × y = answer
10 + 10 = 20 so 20 is the answer! Hope that helps!

Step-by-step explanation:
If A is the center of the circle then which statement explains how line GH is related to line FH
Answer:
D. GH = FH because FG is perpendicular to the radius of a circle A.
Step-by-step explanation:
A circle has different parts which include but no limited to; diameter, chord, radius, segment, sector, circumference etc. This, it can be observed that FG is a chord on circle A, and a chord is always perpendicular to the radius of the circle that bisects it. This implies that FG has been bisected into two equal haves of FH and GH by the radius AH.
Therefore, since FG is at a right angle to AH, then it is true that GH = FH. So that the appropriate answer to the given question is option D.
For the right triangles below, find the exact values of the side lengths a and c. If necessary, write your responses in simplified radical form.
Answer:
First triangle: [tex]a = 5\sqrt{2}[/tex], second triangle: [tex]c = \frac{8\sqrt{3}}{3}[/tex]
Step-by-step explanation:
In the first triangle, the value of [tex]a[/tex] is equal to the following trigonometric relation:
[tex]a = \frac{5}{\cos 45^{\circ}}[/tex]
[tex]a = \frac{5}{\frac{\sqrt{2}}{2} }[/tex]
[tex]a = \frac{10}{\sqrt{2}}[/tex]
[tex]a = \frac{10\sqrt{2}}{2}[/tex]
[tex]a = 5\sqrt{2}[/tex]
In the second triangle, we obtain the value of [tex]c[/tex] is equal to the following trigonometric relation:
[tex]c = 8\cdot \tan 30^{\circ}[/tex]
[tex]c = 8 \cdot \left(\frac{\sin 30^{\circ}}{\cos 30^{\circ}} \right)[/tex]
[tex]c = 8\cdot \left(\frac{\frac{1}{2} }{\frac{\sqrt{3}}{2} } \right)[/tex]
[tex]c = \frac{8}{\sqrt{3}}[/tex]
[tex]c = \frac{8\sqrt{3}}{3}[/tex]

Find the gradient of the line segment between the points (-4,4) and (0,12).
Answer:
2
Step-by-step explanation:
the gradient = (12-4)/(0+4)=8/4=2
Answer:
gradient = 2
Step-by-step explanation:
Calculate the gradient m using the gradient formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 4) and (x₂, y₂ ) = (0, 12)
m = [tex]\frac{12-4}{0+4}[/tex] = [tex]\frac{8}{4}[/tex] = 2

Describe how to solve x−6=−12.
Answer:
See explanation.
Step-by-step explanation:
You have to use the inverse operation of -6 to get x by itself. So you have to add 6 to each side to get rid of the -6. And -12+6=-6. So, x=6.
Answer:
X is -6
Step-by-step explanation:
You have to add 6 to both sides like -6+6 and -12+6
-12+6=-6 which is the answer because -6-6 is -12

Answer:
x = -2
Step-by-step explanation:
Subtract 5 from both sides (8x + 5 -5 = 6x + 1 -5);Subtract 6x from both sides (8x - 6x = 6x - 6x - 4);Divide both sides by 2 (2x / 2 = -4 / 2);Answer: x = -2please help no links please!’n
