Coordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = x
y = -x + 4
Step 2: Solve for x
Substitution
Substitute in y: x = -x + 4[Addition Property of Equality] Add x on both sides: 2x = 4[Division Property of Equality] Divide 2 on both sides: x = 2Step 3: Solve for y
Define original equation: y = xSubstitute in x: y = 2Use distributive property to remove the parentheses -5(-2v+3y-1)
Answer:
10v+-15y+5
Step-by-step explanation:
With distributive property, you multiply the number outside the parentheses to the numbers inside the parentheses separately then add them together and combine like terms.
Solve the equation by factoring. Tasha is planning an expansion of a square flower garden in a city park. If each side of the original garden is increased by 7 m, the new total area of the garden will be 144 m^2m 2. Find the length of each side of the original garden.
Answer:
Step-by-step explanation:
Area of enlarged garden will be 144 sq meters. Each side will be √144 = 12 meters.
Side of original garden = 12-7 = 5 meters l.

Terms/CoefficientsCoordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
4x - 3y = -20
-x - 8y = 5
Step 2: Rewrite Systems
-x - 8y = 5
[Addition Property of Equality] Add 8y on both sides: -x = 8y + 5[Division Property of Equality] Divide -1 on both sides: x = -8y - 5Step 3: Redefine Systems
4x - 3y = -20
x = -8y - 5
Step 4: Solve for y
Substitution
Substitute in x: 4(-8y - 5) - 3y = -20[Distributive Property] Distribute 4: -32y - 20 - 3y = -20Combine like terms: -35y - 20 = -20[Addition Property of Equality] Add 20 on both sides: -35y = 0[Division Property of Equality] Divide -35 on both sides: y = 0Step 5: Solve for x
Define original equation: -x - 8y = 5Substitute in y: -x - 8(0) = 5Multiply: -x = 5[Division Property of Equality] Divide -1 on both sides: x = -5Answer:
x = -5
y = 0
Step-by-step explanation:
4x-3y=-20
-x-8y=5 then x = 8y-5
substitute for x
4(8y-5)-3y = -20
32y-20-3y = -20
29y = 0
y = 0
4x-0 = -20
x = -5

Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. Does there appear to be a difference?
Male: 96 75 53 94 79 55 62 65 61 91 64 81 60 63 83
Female: 71 73 92 86 90 67 89 76 89 86 69 88 68 83 72
Answer:
Male: Median: 64.5 and the mean is 70.6
Female: median: 83 and mean is: 79.93
Step-by-step explanation:
For median, you place all of the numbers from lowest to highest, and then find the number in the middle.
For Mean, add up all the numbers, then divide by the amount of numbers there.
For example.

Answer:
(3,12)
Step-by-step explanation:
y = 3x + 3
y = 6x -6
x = 3
y = 12
= (3,12)
Answer:
All you have to do, is find an x that if used in both equations, both equal the same y.
3 x 3 + 3 = 12
6 x 3 - 6 = 12
So, the only thing here is (3, 12)

bob wants to sub 3x + y = 13 into 4x +3y = 6 he needs to do what to get this
Answer:
x = 6.6, y = -6.8
Step-by-step explanation:
Subtract 3 x from both sides of the equation.
y = 13 - 3x
4x + 3y = 6
Replace all occurrences of y with 13 − 3 x in each equation.
-5x + 39 = 6
y = 13 - 3x
Solve for x in the first equation.
x = [tex]\frac{33}{5}[/tex] or 6.6
Replace all occurrences of x with 6.6 in each equation.
y = [tex]-\frac{34}{5}[/tex] or - 6.8
hope this helps, good luck :)

Answer:
215cm
Step-by-step explanation the length labeled 10cm and 15cm is a rectangle ;it will be length ×width
10cm×15cm=150cm
triangle= half ×base ×height
0.5×10cm×9cm=45cm
[0.5×5×3]2 we multiply by 2 because there are two of the same kind =15cm
then we find the area of the rectangle which is at the center of the triangles
5cm×10=50cm
150±50±15=215

FIND THE VERTEX AND GRAPH THE PARABOLA OF

════════ ∘◦❁◦∘ ════════
Answer : (-2,11)════════════════════
Known thaty = -2x² - 8x + 3
════════════════════
Way to do + explanation#First, find the x coordinate first by using the formula of -b/2a
x = -b/2a = -(-8)/2(-2) = 8/-4 = -2
#After getting the x, find the y
y = -2(-2)² - 8(-2) + 3
y = -2×4 +16 + 3
y = -8 + 16 + 3
y = 11
So the vertex is
(-2,11)
════════════════════
Answer:
the vertex is (-2, 11)
Step-by-step explanation:
F(x) = -2X^2 - 8X + 3 can be rewritten as -2(x^2 + 4x) + 3.
We complete the square of x^2 + 4x, obtaining x^2 + 4x + 4 - 4 = (x + 2)^2 - 4
and then we substitute this last result into F(x) = -2(x^2 + 4x) + 3:
F(x) = -2[ (x + 2)^2 - 4 ] + 3, which simplifies to:
F(x) = -2(x + 2)^2 + 8 + 3, or F(x) = -2(x + 2)^2 + 11
Comparing this to the vertex equation (x + h)^2 + k, we see that h must be -2 and k must be 11.
Thus, the vertex is (-2, 11).
