Answer:
(X+9)(X+8)=0
X=-9,-8
Step-by-step explanation:
x^2+ 17x-12=-84
x^2+17x-12+84=0
x^2+17x+72=0
x^2+(9+8)X+72=0
x^2+9x+8x+72=0
X(X+9)+8(X+9)=0
(X+9)(X+8)=0
X=-9,-8
So the value of the X is -9,-8

Solve x^2+ 8x- 6=0 using the Quadratic Formula
Answer:
x=−4+√22 or x=−4−√22
Step-by-step explanation:
Substitute all values in the quadratic formula.
Solve.
Answer:
[tex]\boxed {\sf x= {{ - 4\pm \sqrt{22} }}}[/tex]
Step-by-step explanation:
The quadratic equation is used to find the roots of a quadratic. The formula is:
[tex]x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}[/tex]
when [tex]{ax^2 + bx + c = 0}[/tex]
We are given the quadratic: [tex]x^2+8x-6=0[/tex]
If we compare the given quadratic to the standard form of a quadratic, then:
[tex]a= 1\\b=8 \\c= -6[/tex]
Substitute the values into the formula.
[tex]x = \frac{{ - 8\pm \sqrt {8^2 - 4(1)(-6)} }}{{2(1)}}[/tex]
Solve inside the radical first.
Solve the exponent.
8²= 8*8= 64[tex]x = \frac{{ - 8\pm \sqrt {64 - 4(1)(-6)} }}{{2(1)}}[/tex]
Multiply 4, 1, and -6.
4(1)(-6)= 4(-6)= -24[tex]x = \frac{{ - 8\pm \sqrt {64 - -24}}}{{2(1)}}[/tex]
Add 64 and 24 (2 negative signs become a positive)
64- -24 64+24=88[tex]x = \frac{{ - 8\pm \sqrt {88}}}{{2(1)}}[/tex]
Solve the denominator.
[tex]x = \frac{{ - 8\pm \sqrt {88}}}{{2}}[/tex]
The radical can be simplified. 88 is divisible by a perfect square: 4
[tex]x= \frac{{ - 8\pm \sqrt {4}\sqrt{22} }}{{2}}[/tex]
Take the square root of 4.
[tex]x= \frac{{ - 8\pm 2\sqrt{22} }}{{2}}[/tex]
Divide by 2.
[tex]x= {{ - 4\pm \sqrt{22} }}[/tex]
The roots are: x=0.690416 and x=−8.69042
Graph the line that contains the point (-3,1) with a slope of 2/3
Answer:
The graph of the line [tex]y=\frac{2}{3}x+3[/tex] that contains the point (-3,1) with a slope of 2/3 is attached below.
Step-by-step explanation:
We know that the slop-intercept form of the equation is
[tex]y=mx+b[/tex]
where m is the slope, and b is the y-intercept.
Given the slope = m = 2/3, and point (-3, 1)
[tex]1=\frac{2}{3}\left(-3\right)+b[/tex]
[tex]-\frac{2}{3}\cdot \:3+b=1[/tex]
[tex]-2+b=1[/tex]
[tex]b=3[/tex]
so the equation of line will be:
[tex]y=mx+b[/tex]
[tex]y=\frac{2}{3}x+3[/tex]
Also, the graph of the line [tex]y=\frac{2}{3}x+3[/tex] that contains the point (-3,1) with a slope of 2/3 is attached below.

Tyler’s brother earns a commission. He makes 2.5% of the amount he sells. Last week, he sold $900 worth of shoes. How much was his commission?
Answer:
$22.5
Step-by-step explanation:
multiply 900 by .025 to get 22.5.
When you multiply by a percentage to find an ammount, move the decimal place over to the left by 2 places and then multiply by the number (in this case 900). Whatever number you recieve is the answer.
The total commission Tyler's brother was earn is $22.5 and this can be determined by using the unitary method.
Given :
Tyler’s brother earns a commission. He makes 2.5% of the amount he sells.Last week, he sold $900 worth of shoes.The following steps can be used in order to determine the total commission Tyler's brother was earn:
Step 1 - The unitary method can be used in order to determine the total commission Tyler's brother was earn.
Step 2 - According to the given data, he sold $900 worth of shoes which is 100% value.
Step 3 - If 100% is $900 then the value of 2.5% is:
[tex]=\dfrac{2.5}{100}\times 900[/tex]
Step 4 - Simplify the above expression.
= $22.5

it will take 1 hour to catch up to train a but if the question means from as soon as train a leaves, it is 3 hours.
The time taken by train B to cover the distance of 56 km when the train at the station is in 1 hour.
What is kinematics?It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
Train A leaves a station traveling at 28 km/hr.
Two hours later train B leaves the same station traveling in the same direction at 84 km/hr.
The distance traveled by the train A in two hours will be
[tex]\rm D_A=28 \times 2 = 56 km[/tex]
Then the distance between the trains when train B is at the station is 56 km.
Then the relative speed of the train will be
[tex]\rm V_{BA} =84 - 28 = 56 \ km/hr[/tex]
Then the time taken by train B to cover the distance of 56 km is in 1 hour.

. A sample of 250 cans of peas showed an average weight of 14 ounces with a standard deviation of 0.7 ounces. If the distribution is relatively normal, how many cans will weigh over 14.7 ounces?
Answer:
40 cans weigh over 14.7 ounces
Step-by-step explanation:
Given
Mean = 14 ounces
SD = 0.7
We have to find the z-score for 14.7 first
[tex]z = \frac{14.7-14}{0.7}\\z = \frac{0.7}{0.7} = 1[/tex]
As we have to find the number of cans greater than 14.7, forst we will find the area to the left of obtained z-score and then subtract from 1.
So,
P(z<1) = 0.8413
Now,
P(z>1) = 1 - P(z<1) = 1-0.8413 = 0.1587
As the total number of cans is 250,
The cans which weigh over 14.7 are:
= 0.1587 * 250
= 39.675
Rounding off to nearest whole number
40 cans
Hence,
40 cans weigh over 14.7 ounces
Answer:
40 cans

Q: The graph shows the cost C in dollars of w pounds of blueberries, a proportional relationship. Select ALL the true statements.
A. 1 lb (pound) of blueberries cost $2.75
B. 2.75 lbs (pounds) of blueberries cost $1
C. 5 lbs (pounds) of blueberries cost $15.50
D. 12 lbs (pounds) of blueberries cost $33
E. The point (3,9) is on the graph of the proportional relationship.
A, D
Step-by-step explanation:
Cost ($) = C
lbs (Blueberries) = W
One pound of blueberries costs $2.75 because to find how much 1 lb is you need to divide by 6.
6 is the number of pounds at that point in the graph, so you divide both the pounds and cost by 6 to find how much 1 lb is.
To find how much 5 lbs costs, multiply both the cost and number of pounds ($2.75 to 1 lb) by 5.
2.75 * 5 is 13.75 (This means C is wrong)
Do the same but with 12 for D
2.75 * 12 is 33, so D is correct
You could do the same method as above for E, but the easier way to do this is to see that the relationship of 3:9 is equal to a 1:3 ratio, which is the same as what the pounds to cost ratio is (which is 1:2.75)
Hope this helps! ^_^
