What is the slope of the line?
-3/2
slope = rise/run
We can use the two points to calculate rise (y value change) and run (x value change)
slope = (-6)/4 = -3/2
PLEASE HELP !!! ILL GIVE BRAINLESS
Answer:
a. ∠G = 180 - (90 + 32)
b. ∠G = 58°
c. ∠J = 180 - 58°
d. ∠J = 122°
Step-by-step explanation:
Angles are added to result in 180°
when the line is straight; thus:
a.
∠G = 180 - (90 + 32)
b.
∠G = 180 - 122
∠G = 58°
c.
∠J = 180 - 58°
d.
∠J = 122°

Out of the 232 media executives, 6 of them control 90% of all media outlets. If there are a total of 400 major
media outlets, how many are controlled by those 6 executives.
Answer:
360
Step-by-step explanation:
6 executives control 90% of the 400 major media outlets
so we need to find 90% of 400
first, convert 90% to a decimal and multiply
0.9•400 gives us 360
so 360 media outlets are controlled by those 6 executives
hope this helps babe <3

Hi can someone tell me what this is in y=mx+b please?
Answer: y= 5x +7
Slope is rise over run. From the two given points we rise 10 and run 2 which is 10/2 or 5.
7 is how high/low we are when we are at x=0
Answer:
Hi!
y= 5x+7
The five is the slope and i counted from the point on the y axis until the next point on the line. Which is 10/2. simplified that is 5/1 or just 5.
The seven in where the line intercepts the y axis.
Hope this helps! Have a good day and don't forget to be tiger fierce!! :)
what is the solution to the system of equations x-y=5 and 3x+7y=-5
Answer:
Step-by-step explanation:
3(x-y)-3x-7y=3(5)-(-5)
3x-3y-3x-7y=15+5
-10y=20
y=-2, since x-y=5
x-(-2)=5
x+2=5
x=3
So the solution is the point (3,-2)

Step-by-step explanation:
b for which -x^2+8x+20=b will have no real roots
Answer:
Step-by-step explanation:
-x² + 8x + 20 = b
-x² + 8x + 20 - b = 0
a = -1 ; b = 8 ; c = 20 - b
There is no real roots.
So, b² - 4ac < 0
Plug in a, b and c values
8²- 4(-1)(20-b) < 0
When we multiply (-1) and (-4), we will get 4
64 + 4(20 - b) < 0
64 + 4*20 - 4b < 0
64 + 80 - 4b < 0
144 - 4b < 0
Subtract 144 from both sides
-4b < -144
Divide both side by -4 and when we are dividing by (-4), < will change to >
b > -144/-4
b > 36
So, when value of b is greater than 36, the equation will have no real roots.
Write the equation of a line that has a slope of 3 and passes through the point (5, 7).
O y = 3x + 8
O y = 5x + 7
O y = 3x - 8
O y = 7x + 5
Answer:
y = 3x - 8
Step-by-step explanation:
All the options are written in slope-intercept ( [tex]y = mx + b[/tex]) form. So, what we can do with the given information is write the equation in point-slope form first, then convert it to slope-intercept form.
1) First, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to find the point-slope equation of the line. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute 3 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, substitute the x and y values of (5,7) into the appropriate places in the formula as well. This gives the following equation of the line in point-slope form:
[tex]y-7 = 3(x-5)[/tex]
2) Now, isolate y in the above equation to find its slope-intercept form.
[tex]y-7=3(x-5)\\y-7 = 3x-15\\y = 3x -8[/tex]
Thus, the answer would be the third option as it matches the result we received.

A soccer field is a rectangle 90 meters wide and 120 meters long. The coach asks the players to run from one corner to the corner diagonally across the field. How far do the players run?
Answer:
150 meters
Step-by-step explanation:
Answer:
150 metresStep-by-step explanation:
We can imagine the rectangle, when cut diagonally it forms a Right angled Triangle
Using this we can find the diagonal i.e hypotenuse.
From the question we know that,
Length = 120 metres
Width = 90 metres
So we can find the diagonal by keeping it as x using the pythogorean theorem.
[tex] {120}^{2} + {90}^{2} = {x}^{2} \\ 14400 + 8100 = {x}^{2} \\ 22500 = {x}^{2} \\ x = \sqrt{22500} \\ x = 150[/tex]
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=71°, and DB = 67 feet. Find the length of BC to the nearest tenth of a foot.
Answer:
in triangle BCD
relationship between base and hypotenuse is given by cos angle
cos 71=b/h
cos71=BD/BC
cos71=67/x
x=67/cos71=205.8ft.
the length of BC to the nearest tenth of a foot is 206ft.

Which equation matches the hanger?
y = 6.3
3y = 6.3
y/3 = 6.3
y + 3 = 6.3
Answer:
B 3y=6.3
Step-by-step explanation:
On the hangers left side there are 3 Y's so we would put that together as 3y
On the hangers right side there is a rectangle with a whole of 6.3
The 3y would equal with the 6.3

Sally invests £8000 in a savings account.
The account pays 2.8% compound interest per year.
Work out the value of her investment after 4 years.
Give your answer to the nearest penny.
Answer:
£8934.34
Step-by-step explanation:
[tex]8000 * 1.028^4 = 8934.34[/tex]
rounding to 2dp
if trunctuated at 2dp however, 8934.33
the number is multiplied by 1.028 to the power of four as you go through the equation four times, so it would be the same as
x * n * n * n * n, where it would simplify to x * n^4

The quadradic formula is:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
When:
[tex]ax^2+bx+c[/tex]
This is the standard form of a quadradic equation.
We have the equation:
[tex]3x^2+5x-2\\\\[/tex]
Recall the standard form.
'3' is in a's place, '5' is in b's place, and '-2' is in c's place.

BA = 8, BA = 30
BA = 8, AC = 16
BA = 8, AC = 8√2
BA = 8, AC = 8√3
Answer:
D. BA = 8, AC = 8√3
Step-by-step explanation:
First, because this is a right triangle, refer to the trigonometric ratios:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
BA is the opposite side to the angle measure given, ∠C—which is 30°—and we have the measure of BC. BC is the hypotenuse, as it is across from the right angle of the right triangle. So we can use sine:
sine = opposite side/hypotenuse
sin(30) = BA/16
sin(30) / 1 = BA / 16
Cross multiply:
BA = sin(30) (16)
BA = 8
AC is the adjacent side to the angle measure given, ∠C—which is 30°—and we have the measure of BC. BC is the hypotenuse, as it is across from the right angle of the right triangle. So we can use cosine:
cosine = adjacent side/hypotenuse
cos(30) = AC/16
cos(30) / 1 = AC / 16
Cross multiply:
AC = cos(30) (16)
AC = 8√3
You can check by using the Pythagorean Theorem:
a² + b² = c²
8² + (8√3)² = 16²
64 + 192 = 256
256 = 256
