Answer:
3675
Step-by-step explanation:
Use the order of operations. Just go from left to right. So, 7 times 7 equals 49. Then, 49 times 7 equals 343. Then, divided by 7 equals 49. 49 times 75 equals 3675. I hope this helps.
Which graph represents the solution to the linear system
Sy=-3x-5
-5?
y= 3x +1
Answer:
Step-by-step explanation: both graphed is D
The graph D represents the solution of the system of the equation.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given, the system of equation;
y = -3x - 5 {equation 1}
y = 3x + 1 {equation 2}
Add both of the equation:
2y = -4
y = -2
And x = 1
And the solution set is (1 , -2).
And only D have the solution set (1 , -2)
Therefore, the graph D represents the solution of the system of the equation.

Given:
The figure of a triangle DEF.
To find:
The coordinate of image of given triangle after reflection over y-axis.
Solution:
The vertices of given triangle are D(1,4), E(4,3), F(2,0).
If a figure is reflected over the y-axis, then the rule of reflection is
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]D(1,4)\to D'(-1,4)[/tex]
[tex]E(4,3)\to E'(-4,3)[/tex]
[tex]F(2,0)\to F'(-2,0)[/tex]
Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).

Answer:
0.98
Step-by-step explanation:
0.98 would be the most logical answer. If there is a 0.2 percent chance, it has a 20% chance of happening, which isn't likely. If there is a 0.5 percent chance, it is split so it can't really be likely or unlikely. Whereas having a 0.98 percent chance means there's a 98% of it happening.

Answer:
x = 9 (it is seriously not drawn to scale)
Step-by-step explanation:
BC = DC^2 + BD^2 (Pythagorean theorem)
BC = 4^2 + 6^2
BC = 16 + 36
BC = 52^2
BC = 2sqrt13
BC/AB = DC/BD
(2sqrt13)/AB = 4/6
6(2sqrt13) = 4(AB)
12sqrt13 = 4AB
3sqrt13 = AB
AC^2 = AB^2 + BC^2 (Pythagorean Theorem)
AC^2 = (3sqrt13)^2 + (2sqrt13)^2
AC^2 = 117 + 52
AC^2 = 169
AC = 13
AD + DC = AC
AD + 4= 13
AD = 9

You have 23 questions and each questions takes 2 minutes and two weeks to complete what is the longest time you have to finish it
Answer:
46 minutes
Step-by-step explanation:
Number of questions = 23
Time taken per question = 2 minutes
The longest time available to finish all questions :
Longest time will be ; if one spends all two minutes on each question ;
Then ;
Longest time = number of question * maximum time per question
Longest time = 23 * 2 = 46 minutes

What is the value of X
Answer:
112*
Step-by-step explanation:
The easy way to figure this out is to take the two numbers we do have and add them together. 50 + 62 = 112
We now now the complete angle if that line was not there in the middle. and sice that angle is the same at angle X it is automatically the same, 112. If you don't understand please comment and let me know.
Find the angle measure of angle E in Triangle DEF if angle D is 34 degrees & angle E is 117 degrees.
Answer:
m∠E = 29°Step-by-step explanation:
The sum of the measure of the interior angles in a triangle is 180°
m∠D + m∠E + m∠F = 180°
34° + m∠E + 117° = 180°
m∠E = 29°

8-2x = -8x + 14
O x=-1
O x= -3/5

x = 1
Ashley is saving for a computer that costs $500. She has saved up $120
so far. Which inequality represents the amount of money, m, Ashley still
needs to save? *
O m > $120
O m<$120
O m< $380
O m > $380
Answer:
m > $380
Step-by-step explanation:
First, the math:
$500-$120= $380.
She still needs $380.
Her $380 still needed is less than m, which gives us the last answer the most logical.

Answer:
x=1
Step-by-step explanation:
given
21=14+7x
our objective is to get the variable (x) by itself
To do so we use inverse operations
so to get rid of the 14 we subtract 14 but whatever you do to one side you have to do to the other so we subtract each side by 14
14-14 cancels out
21-14=7
now we have
7x=7
now we want to get rid of the 7
to do so we divide by 7 but remember whatever we do to one side we have to do to the other side so we divide each side by 7
7/7 cancels out
7/7=1
we're left with x=1
hope this helps!
