Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8

Find the area of the triangle below:
Answer:
9 cm^2
Step-by-step explanation:
The area of a triangle is calculated with the following formula:
1/2*b*h (b: base, h: height)
The base is given as 3 and height is 6 so
1/2*3*6 = 9 cm^2 is the answer we are looking for.
Put the steps in correct order for the equation Solve 3(2x−7)+5=−19
Answer:
6x-21+5 = -19 Distribute
6x-16 = -19 Combine like terms
6x = -3 Add
x = -1/2 Division
Answer: x=-1/2 in decimal form -0.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*(2*x-7)+5-(-19)=0
3 • (2x - 7) + 5) - -19 = 0
Pull out like factors :
6x + 3 = 3 • (2x + 1)
Solve : 2x+1 = 0
Subtract 1 from both sides of the equation :
2x = -1
Divide both sides of the equation by 2:
x = -1/2 = -0.500
An ice-skating competition lasted three days. Day one had an attendance of 16,390 people. Day two had an attendance of 16,550 people. Day three had an attendance of 16,237 people. Write the days in order from least attendance to greatest attendance. Use words or numbers to show how you know.
Answer:
[tex]Day\ 3 = 16237[/tex]
[tex]Day\ 1 = 16390[/tex]
[tex]Day\ 2 = 16550[/tex]
Step-by-step explanation:
Given
[tex]Day\ 1 = 16390[/tex]
[tex]Day\ 2 = 16550[/tex]
[tex]Day\ 3 = 16237[/tex]

Answer:
The third one x+49+28=180
Step-by-step explanation:
We can say that the angle between the 29° angle and the 49° angle is equal to x, since they are vertically opposite angles.
The sum of 28+49+x is equal to a supplement angle which is a straight line essentially
We can then say x+28+49=180
:)
If you want to calculate x,
x=180-28-49
x=103
an art teacher had 2/3 gallon of paint to pour into containers. if he poured 1/8 gallon of paint into each container until he ran out of paint, how many containers had paint in them, including the one that was partially filled?
1
SEE ANSWER
Answer:
6 containers
Step-by-step explanation:
This problem is asking us to divide the total 2/3 gallons by the 1/8 gallon of paint being poured into each container.
Given:
[tex]\frac{2}{3} /\frac{1}{8}[/tex]
"Keep, change, and flip:"
[tex]\frac{2}{3}*\frac{8}{1}[/tex]
Multiply across:
[tex]\frac{2*8}{3*1} =\frac{16}{3}[/tex]
Simplify:
5 [tex]\frac{1}{3}[/tex]
Since the problem is counting the one partially filled, we round 5 [tex]\frac{1}{3}[/tex] up to be 6 containers with paint in them.

Round 324,145
to the nearest
hundred thousand.
Answer:
320,145
Step-by-step explanation:
Anything under 5 goes down and anything above 5 goes up.
Answer:
300,000
Step-by-step explanation:
Given the following question:
[tex]324145[/tex]
To round to the nearest hundred thousand of this number we must first find the hundred thousand place value and then determine if the number next to that place value is greater than five, if so, we can round the number up.
[tex]324145[/tex]
[tex]PV=3[/tex]
[tex]2 < 5[/tex]
[tex]=30000[/tex]
Rounded to the nearest hundred thousand "300,000" is your answer.
Hope this helps.

Tiana placed two orders for flowers and bushes. The first order was for 24 flowers and 6 bushes. The total cost of the first order was $144. The second order was for 18 flowers and 3 bushes. The total cost of the second order was $90. What is the cost of each plant?
Answer:
Step-by-step explanation:
24x + 6y = 144.
18x + 3y = 90.
Divide the (24x + 6y = 144) by 3.
8x + 3y = 48.
18x + 3y = 90.
Cancel the 3y.
8-18x = -10x.
48-90 = -42.
-10x = -42.
x = 4.2
8(4.2) + 3y = 48.
33.6 + 3y = 48.
Cancel out the whole number.
3y = 14.4
y = 4.2
The cost of a flower is $3 and a bush is $12.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.
Given:
Tiana placed two orders for flowers and bushes.
The first order was for 24 flowers and 6 bushes.
The total cost of the first order was $144.
The second order was for 18 flowers and 3 bushes.
The total cost of the second order was $90.
Let x be the number of flowers and y be the number of bushes.
So, we have a system of equations,
24x + 6y = 144
18x + 3y = 90
Simplifying,
4x + y = 24
6x + y = 30
Subtracting the equations,
we get,
2x = 6
x = 3, and y = 12
Therefore, the solution is x = 3, and y = 12.

What is the y intercept function f?
Type the correct answer in each box. Spell all the words correctly, and use numerals instead of words for numbers. If necessary, use / for the fraction bar(s). We can show that ∆ABC is congruent to ∆A′B′C′ by a translation of unit(s) and a across the -axis. Reset Next
Answer:
We can show that ∆ABC is congruent to ∆A′B′C′ by a translation of (x-2, y) unit(s) and a across the x-axis.
Step-by-step explanation:
The triangle ABC is shown in the image attached. The coordinates of the triangle are A(8, 8), B(10, 4), C(2, 6), while the triangle A'B'C' is at A'(6, -8), B'(8, -4), C'(0, -6).
A transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, dilation and rotation.
If a point O(x, y) is translated a units on the x axis and b units on the y axis, the new coordinate is O'(x+a, y+b).
If a point O(x, y) is reflected across the x axis, the new coordinate is O'(x, -y)
Hence if triangle ABC is translated -2 units on the x axis (2 units left), the new coordinates are A*(6, 8), B*(8, 4), C*(0, 6). If a reflection across the x axis is then done, the new coordinates are A'(6, -8), B'(8, -4), C'(0, -6).
Answer:
We can show that ∆ABC is congruent to ∆A′B′C′ by a translation of 2unit(s) left and reflected across the x-axis.

Find two integers with a product of −40 and a sum of −3.
Which of the following are lengths of the sides of a 30°-60°-90° triangle? A. 5√3, 15., 10√3 units B. 3, 4, and 5 units C. √3, 3√3 and 2√3 units D. 5√6, 12√6, and 13√6 units
Answer:
A
Step-by-step explanation:
law of sine
c/sin(C) = b/sin(B) = a/sin(A)
with the sides and corresponding angles being always opposite.
sin(90) = 1
sin(30) = 0.5
c, the Hypotenuse, is the longest side in such a right-angled triangle.
c/1 = b/0.5
b = c×0.5 = c/2
so, one side has to be half the length of the longest side (Hypotenuse).
the only answer meeting that criteria is A.
the longest side is 10×sqrt(3) = 17.32...
the side half of that is 5×sqrt(3).
and Pythagoras for such a triangle is then
c² = (c/2)² + a²
c² = c²/4 + a²
so, a² = 3c²/4
c² = c²/4 + 3c²/4
therefore we can check also the third side
15² = 3×(5×sqrt(3))² = 3×25×3 = 3×75 = 225 = 15²
correct.
A is such a triangle.
