Use substitute to determine if x=-4 is a solution to the equation. 5+3x=-7 fill in is or is not.
Answer:
Does fill in!!!!
Step-by-step explanation:
1st substitute x with -4
5+3(-4)=-7
2nd step multiply
5-12=-7
3rd step subtract
-7=-7
so yes -4 is correct!!!!
Answer:
-4 is a solution
Step-by-step explanation:
x = -4
Equation:
5 + 3x = -7
Substitute x for -4
New equation:
5 + 3 x -4 = -7
Solve:
3 x -4 = -12
5 + -12 = -7
-7 = -7

find the product below in standard polynomial form. (show work) (x+3(x-3)(x+7)
Answer:
4x^2 + 19x - 63
Step-by-step explanation:
3(x-3) = 3x - 9
x + 3x - 9 (x + 7)
(4x -9)(x + 7) = 4x(x) + 4x(7) - 9x - 9(7)
4x^2 + 19x - 63

Answer: English please
Step-by-step explanation:
Are the lines parallel, perpendicular, or neither show work cause I need to understand this
Answer:
Niether
Step-by-step explanation:
the slopes arent opposite so they arent perpendicular, they arent the same so they arent parallel. they are niether due to thier slopes, but if they had the same slope, the y intercept would have to be different for them to be parrallel or else they would be the same line

Write ways to represent the fraction 10/9.
Answer:
mixed number form 1 1/9
decimal form 1.11111111111111 it goes on forever
percent form 111.111111111111% it goes on forever (again)
Step-by-step explanation:
i hope that helps!
Answer:
1 1/9
Step-by-step explanation:
10/9, you get 1 as the whole number.
You have a 1 left over when dividing 10 and 9. the 1 will be over 9.
Giving you 1 as the whole number and 1/9 next to it.
Is 2(2x + 3y) = 4x + 6y true or false and how do you know?
Answer:
True because when you multiply the 2 by everything in the parentheses you get 4x + 6y which is 4x + 6y = 4x + 6y. and when you solve it you'll get 0 = 0
Step-by-step explanation:
Answer:
2×2x +2×3y=
4x+6y
Step-by-step explanation:
you first clear the bracket as i have shown above
you use the one outside the bracket to multiply the ones inside the bracket and when you multiply you get 4x+6y

What is the slope of the line passing through
(4,56) and (5,70)
Answer:
14
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points and simplify:
(y2 - y1) / (x2 - x1)
(70 - 56) / (5 - 4)
14 / 1
= 14
So, the slope of the line is 14.
Answer:
m=14

A piece of wire in the form of a rectangle 18 cm long and 15 cm wide is bent and reshaped as a circle. Find the radius of a circle.
Answer:
r = 12.89
Step-by-step explanation:
18(2) + 15(3) = 81 = C
C = 2πr
81 = 2πr
81/2 = πr
r = 81/2π ≈ 12.89

Answer:
B)[tex]y=\frac{-2}{3}x-\frac{-13}{3}[/tex]
Step-by-step explanation:
2x +3y = 5
3y = -2x + 5
Divide both sides by 3
[tex]\frac{3y}{3}=\frac{-2x}{3}+\frac{5}{3}\\\\y =\frac{-2}{3}x+\frac{5}{3}[/tex]
Parallel lines have same slope.
m = (-2/3) ; (-2 , -3)
y - y1 = m(x -x1)
[tex]y-[-3]=\frac{-2}{3}(x-[-2])\\\\y + 3 = \frac{-2}{3}(x +2)\\\\y + 3 =\frac{-2}{3}x + 2*\frac{-2}{3}\\\\y+3=\frac{-2}{3}x-\frac{4}{3}\\\\y=\frac{-2}{3}x-\frac{4}{3}-3\\\\y=\frac{-2}{3}x-\frac{4}{3}-\frac{3*3}{1*3}\\\\y=\frac{-2}{3}x-\frac{4}{3}-\frac{9}{3}\\\\y=\frac{-2}{3}x-\frac{-13}{3}[/tex]

Answer:
7. Orthocenter is on the triangle, at (0,0).
8. Orthocenter is outside the triangle, at (1,-5)
Step-by-step explanation:
Answer:
7. (0, 0) - on the triangle8. (1, -5) - outside the triangleStep-by-step explanation:
Question 7Given points:
J(1, 3), K(-3, 1), L(0,0)Orthocenter is the intersection of altitudes. Altitude is perpendicular segment with one end on the opposite vertices.
Lets work out two altitudes and find their intersection.
Slope of JL
m(JL) = (0 - 3)/(0 - 1) = 3Equation of the line that is perpendicular to JL and passes through K(-3, 1). The line has the slope -1/3.
y - 1 = -1/3(x - (-3)) ⇒ y = -1/3xSlope of KL
m(KL) = (0-1)/(0 - (-3)) = -1/3Equation of the lines that is perpendicular to KL and passes through J(1, 3). The line has a slope -1/(-1/3) = 3
y - 3 = 3(x - 1) ⇒ y = 3xThe orthocenter is the intersection of the lines:
-1/3x = 3x ⇒ x = 0 ⇒ y = 0The point is (0, 0) which overlaps with point L so it is on the triangle
Question 8Given points:
D(-3, -2), E(-2, -2), F(1,2)Lets work out two altitudes and find their intersection.
Slope of DE
m(DE) = (-2 - (-2))/(-2 -(-3)) = 0, horizontal lineEquation of the line that is perpendicular to JL and passes through F(1, 2). The line is vertical:
x = 1Slope of EF
m(EF) = (2- (-2))/(1 - (-2)) = 4/3Equation of the lines that is perpendicular to EF and passes through D(-3,-2)
The line has a slope -1/(4/3) = -3/4:
y - (-2) = -3/4(x - (-3)) ⇒ y = -3/4x - 17/4The orthocenter is the intersection of the lines:
x = 1y = -3/4 - 17/4 = -20/4 = -5The point is (1, -5) is outside the triangle
