Answer:
y= -1/2x - 2
Step-by-step explanation:
To change standard form to slope intercept form, bring the -x to the other side of the equation.
You'll have 2y=-4-x. Since there is no number on the -x, put a 1 on the front of it. (Not necessary). You'll have 2y= -4 -1x
Make y stand on its own. Divide the other side by 2.
You will end up with y= -1/2x -2
The base of a triangle is 24 millimeters and the height is 7 millimeters. What is the area of the triangle?
Answer:
84
Step-by-step explanation:
area of a triangle is represented by this equation: A= 1/2(b x h)
so we plug in the base for b and the height for h to get A=1/2(24 x 7) and now we solve accordingly. 24 x 7 is 160, and 160 x 1/2 is 84.

A salesperson had $240, 000 in sales last year, which is 60% of the sales she had this year. Which equation could be used to determine x, the salesperson's total amount of sales, in dollars, for this year?
Answer: $400,000
Step-by-step explanation:
Let the salesperson's total amount of sales, in dollars, for this year be represented by x.
Therefore, 60% of x = $240,000
60/100 × x = $240,000.
0.6 × x = $240,000..
x = $240000 / 0.6
x = $400,000
Therefore, the salesperson's total amount of sales, for this year is $400,000.
find the area of the semi circle please
Answer:
58.4197cm^2
Step-by-step explanation
cirlce area formula: [tex]\pi[/tex]r^2
r= 6.1
[tex]\pi[/tex]=3.14
Now plug numbers into the formula
area of circle:
= (3.14)(6.1^2)
=(3.14)(37.21)
= 116.8394cm^2 ------> area of full circle
now divide by 2, to find area of semi circle
116.8394/2= 58.4197cm^2
[tex] \huge\fbox\red{A}\fbox\pink{n}\fbox\purple{S}\fbox\green{w}\fbox\blue{E}\fbox\orange{r}[/tex]
area of semicircle is 58.572 m²
[tex] \huge \sf { \fcolorbox{green}{g}{Explanation :- }}[/tex]
[tex] \huge \underline{\large \fbox \red{Concept : }}[/tex]
We have to find the area of semicircle
So firstly we need to find the area of circle. because the semicircle of circle is the half of area of circle so first we find the area of circle then divide by 1 /2 then we get the area of semicircle.
We have given the radius of circle is 6.1 m
[tex]\huge\mathfrak\red{Solution : }[/tex]
[tex] \mathfrak \green{Area \: of \: circle = π × ( radius) ²}[/tex]
[tex]\mapsto \: \: \small \: \: \: \: \: \mathfrak \blue{ = \frac{22}{7} \: \times( 6.1 \: m)^{2} } \\ [/tex]
[tex]\mapsto \small \: \: \: \: \: \mathfrak \blue{ = \frac{22}{7} \: \times37.21 \: m {}^{2} } \\ [/tex]
[tex]\mapsto \: \small\: \: \: \: \: \: \mathfrak \blue{ = 116.94 \: m {}^{2} }[/tex]
Therefore,
[tex]\small \mathfrak \red{Area \: of \: semicircle = \frac{1}{2} \times area \: of \: circle}[/tex]
[tex] \small \mathfrak \green{ = \frac{1}{2} \times 116.94 \: cm \: {}^{2} } \\ [/tex]
[tex]\mapsto \: \small\: \: \: \: \: \: \mathfrak { = 58.472\: m {}^{2} }[/tex]

Question 1 of 5 Select the correct answer. If the factors of quadratic equation are (x − 7) and (x + 3), what are the x-intercepts? (-7,0) and (-3,0) (-7,0) and (3,0) (3,0) and (7,0) (-3,0) and (7,0)
Answer:
(7,0) and (-3,0)
Step-by-step explanation:
Given the factors, we want to get the x-intercepts
All we have to do is to get the x values by equating the factors to zero
we have this as;
(x -7) = 0 and (x + 3) = 0
x = 7 and x = -3
The x-intercepts are;
(7,0) and (-3,0)

I have two congruent sides.I also have two congruent angle i am (n) -------- that measures 45 each s
Answer:
Isosceles triangle
Step-by-step explanation:
Given
Two congruent angles and two congruent sides
Base on the given description, the concept being described is an isosceles triangle, as it has two congruent sides and two congruent angles.
If each angle measures 45 degrees each, then the third angle is 90 degrees.
This is shown below.
[tex]\theta + 45 + 45= 180[/tex] --- angles in a triangle
[tex]\theta + 90= 180[/tex]
Subtract 90 from both sides
[tex]\theta = 90[/tex]

A model car is made to a scale of 1:50 (model: real). If the model has a length of 10 cm, calculate the length of the real car (answer in meters).
Answer:
5 m
Step-by-step explanation:
A model car is made to a scale of 1:50 (model: real).
If the model has a length of 10 cm, calculate the length of the real car (answer in meters).
We have a scale of :
model: real = 1:50
The model has a length of 10cm
Hence:
1 cm = 50 cm
10 cm = x cm
Cross Multiply
x cm × 1cm = 10 cm × 50 cm
x cm = 10 cm × 50 cm/1cm
x cm = 500 cm
The length of the real car is 500cm
Converting the length of the real car to meters
100cm = 1 m
500 cm = x m
Cross Multiply
100cm × x m = 500 cm × 1 m
x m = 500 cm × 1 m/100 cm
x m = 5 m
The Length of the real car in meters is 5m

Can someone explain their answer?
Answer: -36
Step-by-step explanation:
13, 6, -1
to get from 13 to 6 and 6 to -1, you would subtract by 7 so keep subtracting by 7 until you get 8 different terms
13, 6, -1, -8, -15, -22, -29, -36
the eighth term would be -36
i hope that makes sense
