Explanation:
Replace every x with -3
Then use the order of operations (PEMDAS) to simplify
y = -2x^2 + x - 5
y = -2(-3)^2 + (-3) - 5 ... x replaced with -3
y = -2(9) - 3 - 5
y = -18 - 3 - 5
y = -21 - 5
y = -26
Answer:
-26
Step-by-step explanation:
1. plug in -3 for all x's
-2(-3)^2 + (-3) -5
2. combine like terms
-2(-3)^2 - 8
3. pEmdas. deal with exponent first (remember: only affect the 3, since it's in parentheses! also when you square a negative number, it becomes positive!)
-2(9) - 8
4. peMdas. multiply -2 and 9 next.
-18 - 8
5. pemdaS. subtract 8 from -18.
-18 - 8 = -26

3n - 7m for n = 5 amd m = 4
Answer:
-13
Step-by-step explanation:
first you will subsitute 5 for n in the equation to get 3(5)-7m
next you will subsitute 4 for m in the equation to get 3(5)-7(4)
then solve: 3x5= 15
7x4= 28
15-28= -13

Solve the equations 7(2x+6)=1
Answer:
Step-by-step explanation:
B
Answer:
x = - [tex]\frac{41}{14}[/tex]
Step-by-step explanation:
Given
7(2x + 6) = 1 ← distribute parenthesis on left side
14x + 42 = 1 ( subtract 42 from both sides )
14x = - 41 ( divide both sides by 14 )
x = - [tex]\frac{41}{14}[/tex]

Answer:
She was probably lagging
Step-by-step explanation:
but this happens to me all the time so I feel your pain
Answer:
GCF is Greatest Common Factor.
Explaination:
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.

What is linear pair?Linear pairs of angles are created when two lines cross at a single point. Angles are said to as linear if they are contiguous to one another following the junction of two lines. If two angles are adjacent and their measurements add up to 180°, they are supplementary. As a result, a pair of linear angles always sums to 180°.
In a linear pair, the total of the two angles is always 180 degrees.Angles that are next to one another are called linear pairs, however not all adjacent angles are linear pairs.A common vertex and common arm are shared by a pair of linear angles.Given:
<1 = 5x-15
<2 = 90
<3 = 2x
Now, using Linear pair
5x - 15 + 90 + 2x= 180
7x + 75 = 180
7x = 180-75
7x= 105
x= 105/7
x= 15
Hence, the value of x is 15.

graph a line with a slope of -5 that contains the point (-3, -4)
Answer:
y = -5x-19
Step-by-step explanation:
Use the point-slope formula to plug in the x1 and y1 and the slope -5 to get the equation y = -5x-19.
Formula: y-y1 = m(x-x1)
m = slope
x1 = x-value
y1 = y-value
Answer:
y=-5x-15
Step-by-step explanation:
starts off in point-slope form:
y+4=-5(x+3)
distribute the 5:
y+4=-5x-15
subtract 4 from each side:
y=-5x-20
^that answer is in slope intercept form.
